Okay, controlled porosity. I love that. It's another one of these design possibilities you can get from 3D printing, way, way, way back. When 3D printing was first entering production like that was one of the raps on it. Sometimes there was porosity. We're long past that. We get fully dense parts and we've controlled it to such an extent that there are some kinds of parts where you want to build in the porosity for the the useful effect you get out of it. Did an episode of The Cool Parts Show about these air filters that were made with controlled porosity. That was an idea, a prototype, but now here, it seems like these Innovent pins, real production components made with controlled porosity built in. Did you learn more about that? Like, like, how did they get exactly the porosity they want? How did they achieve that?

Core Technology Molding turned to Mold-Masters E-Multi auxiliary injection unit to help it win a job and dramatically change its process.

Cross-section of IMC nozzle tip shows tapered internal heat-sink fins, which start at the “transition plane,” which is where the solidified material separates from semi-solidified melt on part ejection. Also shown is the novel profile of the tip, which reduces thermal mass for improved temperature control.

So you said you saw a lot of tooling for plastics and even saw a lot of injection molded tooling. So like, let's keep going. What's another example?

Hey, Pete. So I just got back from PTXPO. That's why we did our little Graduate intro. PTXPO is a trade show that's put on by our parent company, Gardner Business Media, and it's a plastics processing show. So it's not an additive-focused show, but there is an additive presence. So we're going to talk about plastics today.

Next Chapter Manufacturing 3D printed these porous metal parts using DMLS. The company uses this technology to produce porous ejector pins that can vent out gases during the molding process.

Strings originate at the molten center of the melt channel in a machine nozzle tip, which often does not solidify within a desirable cycle time.

The IMC nozzle tips cost more than other tips, because they cost more to make. “But the ROI on any mold that has an extended cycle time to overcome or reduce a stringing problem is typically just a few days,” Fattori asserts. “And the money saved from not having to repair just one mold due to string damage can probably pay for a year’s supply of IMC nozzle tips.”

Mold maintenance is critical, and with this collection of content we’ve bundled some of the very best advice we’ve published on repairing, maintaining, evaluating and even hanging molds on injection molding machines.

Core Technology Molding turned to Mold-Masters E-Multi auxiliary injection unit to help it win a job and dramatically change its process.

Okay, so um, you saw a lot of tooling at PTXPO molds, molded components, end-of-arm tooling. Like I think that is just about all the tooling that goes into injection molding, pretty comprehensive.

In this collection of articles, two of the industry’s foremost authorities on screw design — Jim Frankand and Mark Spalding — offer their sage advice on screw design...what works, what doesn’t, and what to look for when things start going wrong.

According to Fattori, most nozzle tips are made of H-13 steel with a Rockwell hardness of 46 to 48 Rc. IMC tips are made of 420 stainless steel with a vacuum bright hardness of 48 to 52 Rc for greater durability.

Take a deep dive into all of the various aspects of part quoting to ensure you’ve got all the bases—as in costs—covered before preparing your customer’s quote for services.

•  Lowering the nozzle-tip temperature, which can increase the risk of cold slugs and nozzle freeze-off, leading to cosmetic flaws in parts and/or to costly downtime;

Nozzle tips with large orifices are more prone to stringing because they take considerably longer to become semi-solid—usually longer than the best possible cycle time. Molders have tried various methods to reduce string formation, each of which has its own drawbacks:

This month’s resin pricing report includes PT’s quarterly check-in on select engineering resins, including nylon 6 and 66.

In this three-part collection, veteran molder and moldmaker Jim Fattori brings to bear his 40+ years of on-the-job experience and provides molders his “from the trenches” perspective on on the why, where and how of venting injection molds. Take the trial-and-error out of the molding venting process.

New system automatically cleans mold-cooling lines—including conformal channels—removing rust and calcium, among other deposits, while simultaneously testing for leaks, measuring flow rate and applying rust inhibitor.

Yeah, so I have pictures and videos of I think everything that I talked about on Twitter and Instagram, we can post links to them in the show notes as well.

Multiple speakers at Molding 2023 will address the ways simulation can impact material substitution decisions, process profitability and simplification of mold design.

Across all process types, sustainability was a big theme at NPE2024. But there was plenty to see in automation and artificial intelligence as well.

This Knowledge Center provides an overview of the considerations needed to understand the purchase, operation, and maintenance of a process cooling system.

Yeah, so the first big example this is sort of the bulk of what I saw was 3D printed injection molded tooling. And I have several sub-examples of this. The first one is Mantle. We've covered them before, but they make a system that's specifically designed for 3D printed mold tooling that uses a flowable metal paste, and a hybrid machine tool. They were at the show presenting a case study with another exhibitor Westminster Tool, which is a mold shop in Connecticut. And they were talking about a project they worked on together, making a mold for a pair of medical tweezers, and Westminster was designing the mold for this part. And it needed to be made out of this 65% glass filled polyamide which is tough to work with. It's abrasive it doesn't flow well and it has narrow molding parameters. So they designed a mold with a conformal cooling channel that would help them mold this material. They designed the mold and mantle printed it, sent over the inserts to Westminster where they did a little bit of postprocessing and then they were able to run thousands of these parts. It was more of a prototyping-type application. And they were able to go from design to part in like three weeks.

According to Fattori, “A nozzle tip undergoes both a constant and cyclical thermal battle. It is heated in the back half by the machine’s nozzle body. It is cooled in the front half by contact with the sprue-bushing seat and by convection into the atmosphere.” These opposing thermal forces are fairly constant and come into equilibrium over time. But, he notes, that equilibrium is upset by the substantial heat generated during each injection cycle from frictional shear of the material.

Exhibitors and presenters at the plastics show emphasized 3D printing as a complement and aid to more traditional production processes.

Plastics processors are finding applications for 3D printing around the plant and across the supply chain. Here are 8 examples to look for at NPE2024.

In this collection, which is part one of a series representing some of John’s finest work, we present you with five articles that we think you will refer to time and again as you look to solve problems, cut cycle times and improve the quality of the parts you mold.

Additive technology creates air pockets in film during orientation, cutting down on the amount of resin needed while boosting opacity, mechanical properties and recyclability.

After four years in development, an injection machine nozzle tip has been commercialized that is said to eliminate problems of stringing and all the compromises that molders make to avoid it. Jim Fattori, inventor of the IMC nozzle tip, has 40 years’ experience as a plastics tooling engineer and consultant. He heads up his own firm, Injection Mold Consulting LLC, in the Philadelphia area, and writes frequently for this magazine (see his monthly Tooling Know-How columns). His newly patented invention is now available from Progressive Components.

While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.

And you told me a little bit about it. And it's a part where like, they showed it to you, but you couldn't photograph it because there's still some confidentiality around their customer. But like, like, what, what industry did it have to do with?

Resin drying is a crucial, but often-misunderstood area. This collection includes details on why and what you need to dry, how to specify a dryer, and best practices.

So that's great. I want to hear about PTXPO, Plastics Technology Expo. New show that our employer has begun Gardner Business Media. Plastics has been on my mind to there are some pretty fundamental advances happening in plastics 3D printed I've gotten interested in I want to talk about. So PTXPO, what was it like?

The ‘DryerGenie’ marries drying technology and input moisture measurement with a goal to putting an end to drying based on time.

As Fattori explains, stringing results when the center of the slug of plastic inside the machine nozzle-tip orifice has not sufficiently solidified when the mold opens. When the part is ejected, it drags thin strings of still-molten plastic after it. Those strings tend to be static charged and therefore stick to the mold. If they hang over the parting line, those thin strings of plastic will hob the mold—even a heat-treated steel tool—eventually leading to flashing. Fattori says that can’t be fixed properly by simply grinding the parting line—it requires an extensive mold rebuild, “all because of a $20 nozzle tip.” He adds, “I know of one molder that spends thousands of dollars a year on mold repairs due to stringing.”

Despite price increase nominations going into second quarter, it appeared there was potential for generally flat pricing with the exception of a major downward correction for PP.

Yeah, so I also talked to Xact Metal, and they have a DMLS system. And one of the really interesting applications that they talked about was their VP of commercial operations, Dave Jankowski, gave a Tech Talk. And he mentioned a case where a customer used the metal 3D printer to repair a mold. So they cut off the damaged part, fixed it in the machine and added new material directly onto the cut surface. And I just thought that was a really interesting application that I hadn't heard of before.

Second quarter started with price hikes in PE and the four volume engineering resins, but relatively stable pricing was largely expected by the quarter’s end.

Exactly. And I have one more tooling example to talk about from the show. Alright, 3D printed end-of-arm tooling for automating injection molding, I talked to Savage Automation. And all they do is 3D printed end-of-arm tooling. They showed me an example of what this typical end-of-arm tooling looks like. And it's usually made out of metal, and it has all these tubes coming out for the vacuum gripping mechanism. So this company designs end-of-arm tooling that has internal channels for the airlines instead of needing the hoses and tubes. And they can make it faster than traditional end-of-arm tooling. And it's also lighter than metal, which means that the robot can move faster and there's less wear on it.

Fattori concedes that the thin fins inside the IMC nozzle will tend to wear, especially with filled materials and/or high injection speeds. Wear will gradually reduce the fins’ effectiveness at heat transfer. “Some tips have been running for over a year now with minimal wear,” Fattori comments. “But let’s say you’re running 33% long-glass filled nylon and you have to replace the tip once a month—that’s still a lot cheaper than having to literally rebuild the mold.”

Yeah. So I think that's a good place to wrap up this part of the conversation. And when we come back from the break, we will talk some more about polymer additive manufacturing.

When, how, what and why to automate — leading robotics suppliers and forward-thinking moldmakers will share their insights on automating manufacturing at collocated event.

Sustainability continues to dominate new additives technology, but upping performance is also evident. Most of the new additives have been targeted to commodity resins and particularly polyolefins.

3.  The overall length of the nozzle tips varies in order to vary the land lengths: The larger the orifice, the longer the land to increase thermal conductivity. If the land lengths were all the same, tips with small orifices would be more susceptible to generating cold slugs, and tips with large orifices could string under almost any condition.

After successfully introducing a combined conference for moldmakers and injection molders in 2022, Plastics Technology and MoldMaking Technology are once again joining forces for a tooling/molding two-for-one.

Despite price increase nominations going into second quarter, it appeared there was potential for generally flat pricing with the exception of a major downward correction for PP.

Yeah. So it's just like, control of the positioning of the laser as it's hard to get hardening the material to leave some microscopic channels through the part, I guess, here's what this reminds me of kind of ejector pins, you have written about additive manufacturing, making cutting tools for machining, like cutting tools, basic fundamental component of CNC machining, so ejector pin basic fundamental component of molding, so here's, like, additive serving conventional processes.

Westminster Tool designed this mold with a conformal cooling channel for a pair of medical tweezers, and Mantle 3D printed it using its TrueShape process.

Yeah, so it depends on a lot of factors, like you know, the how detailed the design of the mold is, and how tough the material that they're molding is, but they said it can be anywhere from 25 to a 1,000 shots with 25 to 200 as sort of being their sweet spot.

Successfully starting or restarting an injection molding machine is less about ticking boxes on a rote checklist and more about individually assessing each processing scenario and its unique variables.

And it's a case of plastics, replacing metal. And we talk about that from time to time. Sometimes things are made of metal, not because you need the metal, but just because machining something out of aluminum is the quickest way to get it. And yeah, now 3D printing in some cases is an even quicker way.

Introduced by Zeiger and Spark Industries at the PTXPO, the nozzle is designed for maximum heat transfer and uniformity with a continuous taper for self cleaning.

So Xact Metal, we like them. Laser powder bed fusion machine, and they make these really little machines that are pretty cost effective, in part because the size is so small, but a lot of the metal parts you want to 3D print precise components, they fit within a smaller build envelope and but laser powder bed fusion, like we always think about starting with a build plate, starting with a flat surface, you're describing starting with an existing tool and building on top of that, I guess, like the most basic question that comes to my mind is, do the metal properties come out the same as the the mold tool you're starting with?

Say “manufacturing automation” and thoughts immediately go to the shop floor and specialized production equipment, robotics and material handling systems. But there is another realm of possible automation — the front office.

Fattori also notes that as plastic cools inside the nozzle tip, it shrinks away from the inner bore surface, which reduces the rate of heat transfer. But the fins are always in contact with the melt and are in close proximity to the center of the melt stream, increasing the effective cooling rate.

While the major correction in PP prices was finally underway, generally stable pricing was anticipated for the other four commodity resins.

So a composite mold tool. That's interesting. We've been talking about 3D printed metal tooling. You see also in some of the more temperature-resistant polymers, sometimes there's short run bridge mold tooling that are 3D printed that way, this kind of sounds like something in between. So the ceramic reinforcement, ceramic, we tend to think of that as heat resistant material toughness to stand up to the pressures of the molding process. Like where does this land in terms of the quantities? Did they give you any sense of the shots you can get out of out of a composite mold tool before it wears out?

One more innovation is very simple, but nonetheless valuable to molders. Fattori explains, “For some reason, you have to physically measure the orifice of most nozzle tips with some kind of tool in order to know their size.” He solves that by engraving the orifice size of each IMC nozzle tip on a wrench flat.

Real-world testing (here with ABS) confirms that the IMC nozzle tip (top) eliminates stringing, regardless of the orifice size or material type.

Successfully starting or restarting an injection molding machine is less about ticking boxes on a rote checklist and more about individually assessing each processing scenario and its unique variables.

This Knowledge Center provides an overview of the considerations needed to understand the purchase, operation, and maintenance of a process cooling system.

So yeah, the Mantle process we've written about that before. We'll put a link in the in the show description to our coverage of this but it's like a 3D printing with this like mud-type material that partially solidifies, can then be machined right in the same process as 3D printed, and then it's baked to a harder state later and becomes production ready mold tooling. It's a) a type of 3D printing process that is different from everything else out there and b) this alternative to get full scale, full production quantity, mold tooling. And now here, Westminster, they’re a mold shop, their business is machining molds, and they're, they're evaluating this other way of making mold tooling, has some new freedoms, like you say, the ease of putting conformal cooling in there. I wonder in your conversation with them any like little nuances that have come out either positive or challenges about like what they're discovering about this process?

Mixed in among thought leaders from leading suppliers to injection molders and mold makers at the 2023 Molding and MoldMaking conferences will be molders and toolmakers themselves.

1.  The thick mass in the front was replaced with a contoured outer shape that corresponds to the internal geometry, with the smallest diameter at the transition plane.

The new tips have eliminated stringing in tests with PS, HDPE, LDPE, PP, PVC, ABS, ASA, acrylic, nylon, acetal, PC and PPS (filled and unfilled). However, Fattori cautions that “these new IMC nozzle tips are only to be used on molds with a stringing problem, or molds for which you cannot reduce the cycle time without having a stringing problem. The new nozzle tips are so efficient at removing heat that they can cause a freeze-off condition, particularly on the smaller orifice sizes.”

Yeah, he said it was it's like a physical thing. It's not a chemical thing. And they said it was sort of a combination of design and manipulation of process parameters.

But yeah, they're made out of steel using DMLS. And they kind of have what they described as a porous structure on the inside that can let gases out without letting any of the material out. And they had this cool demo at their booth with some 3D printed parts that they were submerged in a tank of water and then they had air going up through the parts and you can see the air bubbles coming up through the water to show the porosity.

Across the show, sustainability ruled in new materials technology, from polyolefins and engineering resins to biobased materials.

Your very costly mold in that very expensive press is relying on the performance of a $20 nozzle tip that no one ever checks, and has a high probability of not doing its job. Stop learning from your mistakes and start learning how not to make them.

IMC nozzle tips are made of 420 stainless steel, which is harder than the typical H-13 steel. A simple but helpful added feature is the orifice diameter engraved on the wrench flat, unlike most nozzle tips, so no measuring tool is required.

While the melting process does not provide perfect mixing, this study shows that mixing is indeed initiated during melting.

Fattori realized that the solution to the problem was to get more cooling into the center of the flow channel in the nozzle tip. He came up with the idea of adding inwardly protruding, heat-conducting metal fins inside the bore of the nozzle tip. These fins are angled, with their maximum height 70% into the melt stream, with their peak at a location Fattori calls the “transition plane” inside the nozzle tip, which is where the molten material will separate on part ejection from the semi-solidified plastic. From this plane, the fins taper down to blend with the front orifice diameter. This taper concentrates the cooling at the transition plane, which flow simulation shows is the area where the greatest concentration of thermal gradients occurs inside the nozzle. The temperature differential between the sprue-bushing nozzle seat and the transition plane was found to be as high as 135° F in the simulations. Using fins to concentrate the cooling at the transition plane ensures the separation point is consistently in the same location, which results in repeatable shot sizes, Fattori adds.

Say “manufacturing automation” and thoughts immediately go to the shop floor and specialized production equipment, robotics and material handling systems. But there is another realm of possible automation — the front office.

Even as polymer 3D printing is increasingly being used for production, tooling remains a major application for 3D printing in the plastics industry. Exhibitors at the 2022 Plastics Technology Expo (PTXPO) were showcasing several examples of 3D printed tooling for injection molding. For mold inserts, 3D printing can aid in rapid prototyping, production molds with conformal cooling channels and mold repair. 3D printing can also be used to produce mold components, such as ejector pins with a porous structure that enables gas to escape a mold while containing the material inside. And 3D printed end of arm tooling can be lighter than traditionally produced versions with faster turnaround times.

When compared to the traditional end of arm tooling on the left, the 3D printed EOAT section from Savage Automation on the right is lighter and faster to produce.

The new IMC nozzle tip incorporates four features to greatly increase the rate of heat transfer to compensate for momentary temperature rises:

Peter Zelinski and I talked about all this on the latest episode of the AM Radio podcast. For more details on how 3D printing complements injection molding, listen to the episode above or read on for the transcript.

Exhibitors and presenters at the plastics show emphasized 3D printing as a complement and aid to more traditional production processes.

•  Using a smaller nozzle orifice diameter, which increases the pressure drop through the nozzle tip. That increases shear and often requires a slower injection rate to avoid shear burns—adding to cycle time. What’s more, slow injection through a restrictive bore requires higher injection pressure—risking trouble if the machine is close to being pressure-limited;

Processors with sustainability goals or mandates have a number of ways to reach their goals. Biopolymers are among them.

Yeah, so we've covered this before, but they have done some testing on the material itself. And they're finding that they can integrate the, you know, Mantle material into their already existing mold, machining processes really easily.

So yeah, another example of 3D printed tooling that I saw that wasn't injection molded tooling is 3D printed molded components. So Next Chapter Manufacturing was at the show, and they were showcasing these 3D printed ejector pins. They also do 3D printed injection molded tooling, but they started making these ejector pins that can vent gases out of a mold, and they call them Innovent pins. Get it?

Mike Sepe has authored more than 25 ANTEC papers and more than 250 articles illustrating the importance of this interdisciplanary approach. In this collection, we present some of his best work during the years he has been contributing for Plastics Technology Magazine.

Resin drying is a crucial, but often-misunderstood area. This collection includes details on why and what you need to dry, how to specify a dryer, and best practices.

One more thing: Fattori says, “In case you were wondering, the internal heat-sinking fins have also proven to work well in hot sprue bushings and in hot-runner systems.”

The aim of this presentation is to guide you through the factors and the numbers that will help you determine if a robot is a smart investment for your application. Agenda:  Why are you considering automation? What problems are you trying to solve? How and why automation can help Crunch the numbers and determine the ROI

Yeah, so like you said, this is the first time the show has ever been held. So I don't have a direct comparison. But compared to other events that we've been to since the pandemic started, this one felt the most like a pre-COVID event, it felt a little more normal. I was there at the end of the first day, and most of the second day and foot traffic seemed really good, especially on day two, all of the Tech Talks I went to, the theaters were full, and just the general atmosphere felt really positive.

While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.

Introduced by Zeiger and Spark Industries at the PTXPO, the nozzle is designed for maximum heat transfer and uniformity with a continuous taper for self cleaning.

Okay, so they're prototyping them on a Markforged, they send them out. So what 3D printing process makes the final production tooling?

In this three-part collection, veteran molder and moldmaker Jim Fattori brings to bear his 40+ years of on-the-job experience and provides molders his “from the trenches” perspective on on the why, where and how of venting injection molds. Take the trial-and-error out of the molding venting process.

In this collection, which is part one of a series representing some of John’s finest work, we present you with five articles that we think you will refer to time and again as you look to solve problems, cut cycle times and improve the quality of the parts you mold.

Yeah, that's all they do. They don't even do the printing for the production parts in house. They have a Markforged machine that they use for prototyping, but they ultimately send their work out to a service bureau for printing. And so they can just focus on the design of the part.

3D printed tooling for injection molding, including mold inserts, components and end of arm tooling, were on display at the Plastics Technology Expo.

4.  Diameter of the nozzle-tip face is reduced to decrease the amount of contact area between the face of the tip and the sprue-bushing seat. Other nozzle tips, with their large contact area, are greatly affected by how well, or how poorly, the sprue bushing is cooled. Since every mold is different, these nozzle tips can behave inconsistently from one mold to another. Fattori points out that the reduced contact area also results in greater sealing pressure for the same nozzle touch force, preventing carriage blowback and nozzle leakage.

•  Using sprue break, which adds to cycle time (a little or a lot, depending on how far the barrel is retracted) and can lead to nozzle drool, leakage between the nozzle and sprue bushing (when drooled material obstructs close contact), and deformation of the nozzle tip and/or sprue bushing from repeated banging together—leading to even more material leakage.

I have one more example for you. This one was at the Fortify booth. And they have a DLP system and a resin that's reinforced with ceramic fibers for added toughness. It's really good for making rapid prototype molds. Because you can have a mold that's ready to use it in three days, and you can get a couple hundred shots out of it.

Mixed in among thought leaders from leading suppliers to injection molders and mold makers at the 2023 Molding and MoldMaking conferences will be molders and toolmakers themselves.

Okay, 3D printed end-of-arm tooling. So Savage Automation like is that their whole gig people come to them for 3D printed solutions and end-of-arm tooling?

After successfully introducing a combined conference for moldmakers and injection molders in 2022, Plastics Technology and MoldMaking Technology are once again joining forces for a tooling/molding two-for-one.

Across the show, sustainability ruled in new materials technology, from polyolefins and engineering resins to biobased materials.

The IMC nozzle tips are available with a ½-in. spherical radius, in eight different orifice sizes of 5/32 in. through 3/8 in. in 1/32-in. increments. Fattori says the bore diameters of the IMC nozzle tips are slightly smaller than their nominal size. But even with the internal fins, the resulting flow area is comparable to most “full-flow” style nozzle tips. He also says that his tips’ large internal transition radius “virtually eliminates ‘dead spots’ where material can stagnate.”

As a result, Fattori states, “A nozzle tip must be able to react quickly to temperature changes, so as to prevent formation of strings within the best cycle time.” That requires efficient heat conduction to remove excess heat from the nozzle tip. But rate of heat conduction is affected by the mass of the object: Greater mass slows heat transfer. In Fattori’s view, “Every standard nozzle tip today has a very large mass. It begins at the back side of the wrench flats and extends all the way to the front face of the tip.”

IMC’s novel injection nozzle tip (available from Progressive Components) has internal heat-sink fins to cool the center of the melt channel and prevent strings. Sand-blasted finish reportedly ensures a better seal against the sprue bushing.

Yeah, so for plastics production, I visited the RE3DTECH booth. They're a 3D printing service provider. And they use a whole bunch of different processes, including HP Multi Jet Fusion, and they're starting to see production applications for plastic AM using MJF. And they showed me this like perfect part, that was the perfect example of AM moving into production with plastics, it was a part that was formerly machined from aluminum. And they're now making it from PA12. And they're doing more of a manufacturing on demand type model, and ultimately saving the customer a bunch of money. And it was just sort of the perfect example of that.
