Mirel has a slow crystallization rate. This allows for a longer injection time and better filling of complex geometries. The slow injection speed does not have a negative impact on the overall molding cycle as this time would normally be taken up with pack and hold, which can be shorter with slow injection.

Ultradent's entry of its Umbrella cheek retractor took home the awards for Technical Sophistication and Achievement in Economics and Efficiency at PTXPO.

As part of the commercialization process for Mirel PHA bioplastics, it became necessary to validate the injection molding process for a high-profile consumer products launch.

The analysis in the accompanying Moldflow screen shot shows an example of a family mold with poor balance between cavities. This was the original proposal from the molder. Making family molds for Mirel is not a good option. The flow imbalance that results from the different cavity sizes causes significant scrap. A mold built with this design would result in almost 50% scrap due to either flash or short shots. This issue was avoided by redesigning the mold to be more geometrically balanced with multiple cavities of the same size. This meant moving the location of the thermal sprue between the cavities. It also meant using more thermal sprues than originally planned.

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

One of the most pressing questions was whether hot runners could be used with Mirel, because of its thermal sensitivity. Newell Rubbermaid’s Paper Mate div. (newellrubbermaid.com) had decided to produce a line of pens and mechanical pencils called Biodegradables from Mirel bioplastics. The product line was designed to have 60% biodegradable content from Mirel P1003 injection molding grade. This meant that the barrel, nosecone, and clip would have to be made from Mirel. Once Paper Mate had designed the components it was time to apply traditional engineering tools to analyze the processing of the individual components and to design commercial tools to make the components.

The Moldflow analysis showed the best locations for gates and where end of fill would be. To reduce the amount of regrind and scrap, hot runners and thermal sprues with small cold runners were used for the different mold designs. The combination of thermal sprues with a small hot runner allows for a sub-gate design. This was necessary due to the size of the parts being molded. Smaller parts make it difficult to use full hot-runner systems due to the amount of space required for the hot runner. Using a full hot runner would make the overall dimensions of the mold too large to fit in the small injection molding machines being used for the project.

The best designed and built molds will not run well if the processing is not right. Some key parameters for injection molding Mirel P1003 include the barrel temperature profile, mold temperature, screw speed, screw backpressure, and injection speed. By balancing these parameters it is possible to injection mold Mirel efficiently and economically.

Mirel must be molded using a reverse temperature profile. This means using a higher temperature in the rear barrel sections under the hopper than at the nozzle. A typical process profile would be 360, 350, 330, and 330 F from rear barrel zone to nozzle. The goal is to achieve a melt temperature of 330 to 340 F. The reason for the reverse profile is to control melting of the polymer and limit the amount of molecular-weight loss.

Mirel PHA is very sensitive to mold-filling imbalances. Moldflow analysis of this proposed family mold for Paper Mate Biodegradables components shows severe imbalance that would cause flash and short shots.

For the same reason, the screw speed and backpressure are limited as well. Screw speed and backpressure can contribute significantly to the amount of energy put into the polymer during melting. Typical screw speed for Mirel is 100 rpm and backpressure is typically 50 to 100 psi. A low-shear, general-purpose screw is recommended. It should have a short L/D and compression ratio of 2.2:1 to 2.6:1.

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

Coppes added that the ability to mold septic tanks of this size "opens up a lot of doors" for the company in this marketplace. He noted that there is more demand for polymer septic tanks as replacements for concrete tanks because of the greater strength of the polymer tanks as well as the ease of installation and the fact that no large equipment is required.

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.

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

In order to design the molds for optimum processing and reduce the tooling development time, it was decided to perform Moldflow analysis of the designs before building the molds. The pen and mechanical pencil components were to be made from Mirel P1003, an improved injection grade introduced last year with enhanced stiffness and melt flow. In order to perform a Moldflow analysis, the material to be molded must have appropriate data in the Moldflow database. In order to simulate the injection molding process, Moldflow needs data on melt viscosity under different conditions of shear and temperature, melt density, melt thermal conductivity and heat capacity, and PVT data. Since Mirel P1003 is a new material, no such data existed yet. We would have to have this material analyzed by Moldflow. Analysis of Mirel P1003 was carried out by the Moldflow Plastics Lab in Ithaca, N.Y. A Moldflow database file for Mirel was created and subsequently used to perform the analysis of the proposed mold designs before the molds were built.

This program required multiple molds with four or eight cavities apiece. For the volume of parts to be molded, it was not economical to use single-cavity tools. The second reason for multicavity molds was to optimize shot size. With Mirel, it is important to maintain a short residence time in the barrel while molding. Too much time at elevated temperatures causes significant loss of molecular weight, which will ultimately lead to loss of mechanical properties. Mirel processes best when the barrel-capacity to shot-size ratio is between 2:1 and 4:1. This was another argument for multicavity molds.

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.

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.

Husky Injection Molding Systems, Ltd. (husky.ca) designed the hot runners and thermal sprues to work with Mirel. After an in-house performance test with Mirel, Husky was able to recommend what style of hot runner and thermal sprue would work best with Mirel. The molders then designed each injection mold using the recommendations from Husky, the results of the Moldflow analysis, and the recommendations from the Mirel technical services team.

Coppes told PlasticsToday that the company's success with its 1000-gallon septic tanks led the market to demand tanks in a 1500-gallon size. Infiltrator is the world's largest septic products company. Molding a tank this large required a 6,000-ton low-pressure injection molding machine. "We brought in a lot of resources to help us redesign and engineer a press to make it suitable for our needs," Coppes explained. Infiltrator molds its own product and parts requirements in-house, and also has a number of regular injection molding presses to mold its other products.

Phillips noted that the biggest challenge was the logistics involved in delivering the mold. After the mold was built, it was disassembled and placed on a fleet of 15 trucks for shipping from Lansing, MI, to Winchester, KY.  A team of moldmakers was then sent to Kentucky to re-assemble the mold on Infiltrator's plant floor.

Bret Marschand, senior development manager for Newell Rubbermaid Office Products conducted a thorough evaluation of various biobased materials for use in the company’s products. he selected Mirel for its unique combination of performance and biodegradability.

The mold is built with aluminum core and cavity, housed in a steel mold base in what is known as a "hybrid mold" and took more than 10,000 man-hours to build.  The cavity work was done using multiple Tarus 5-axis mills with table sizes of 114" x 120." It also contains the largest hot runner manifold system in operation in the world, explained Todd Phillips, VP of Franchino, which specializes the design engineering and manufacturing of very large molds to produce products that challenge the limits of injection molding. "This is the largest mold we've made to date," Phillips told PlasticsToday.

It is important that molds are designed with proper vents and gates. Mirel does not mold well with large vents or very small gates. Due to the viscosity profile of Mirel, large vents cause flash. It is recommended that vents for Mirel be 0.0005 in. deep. Small gates cause too much shear when molding, which tends to lengthen the overall injection molding cycle. In addition, the heat generation from gate shear causes shear thinning of Mirel resin, increasing the potential for flash. Since these molds were being designed and built specifically for Mirel, we were able to make sure that the proper design recommendations were incorporated into the design. (Complete injection mold design recommendations can be found at mirelplastics.com.)

Mirel is a family of bioplastic materials with physical properties comparable to petroleum-based resins. Mirel is both biobased and biodegradable in natural soil and water environments and in home and industrial composting systems. Mirel is a type of PHA (polyhydroxyalkanoate)— specifically, a proprietary blend of PHB (polyhydroxybutyrate) copolymers, additives, and mineral fillers. It is a type of semicrystalline thermoplastic polyester that is derived from microbial fermentation of corn sugar. The rate and extent of Mirel’s biodegradability will depend on the size and shape of the articles made from it. However, like nearly all bioplastics and organic matter, Mirel is not designed to biodegrade in conventional landfills.

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

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.

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.

The other critical process parameter for Mirel is the mold temperature. It should be controlled at 140 F. This is very important for Mirel because its fastest rate of crystallization occurs at 140 F. A small deviation from this will have a significant impact on the cooling time needed to eject parts from the mold. Cooling the mold below 140 F does not speed the crystallization rate and will increase the cooling time. As little as a 20° F deviation will double the cooling time needed.

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.

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

All Mirel bioplastics are thermally sensitive and must be dried to a low moisture content (0.1%). Their thermal sensitivity is a primary factor distinguishing proper molding technique for Mirel from that for other thermoplastics.

Mirel also responds best to a slow injection speed. This is, again, partly in order to minimize gate shear and shear heating. A short, reverse-taper nozzle is recommended.

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.

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.

The molders have been operating the injection molds for the Paper Mate Biodegradable pens and mechanical pencils for several months with minimal issues. Efficiency continues to be improved in the overall molding process, and reduced cycle times have been achieved relative to traditional plastics. The molds are all running with minimal scrap—approximately 4%. We have been able to process several different lots of Mirel P1003 with minimal adjustment to the molding process. This, combined with the lower processing temperatures, results in significantly lower energy consumption to produce the Paper Mate Biodegradable pens and mechanical pencils from Mirel P1003 relative to conventional plastics. Measurements show a 20% reduction in electrical consumption in molding the mechanical pencils as compared with ABS or polycarbonate. Modeling indicates a similar reduction in energy for the pens.

Franchino employs 85 people currently, but that will change as the company's expansion plans evolve. Phillips noted that the company recently purchased another 62,000-sf facility behind a current plant and the two buildings will be connected. "We're going through the building modifications now and moving equipment in, which will include a 50-ton crane to accommodate the larger sizes of the molds we build," he said.

What's happening across the country is that the cost of expanding sewer plants has risen and a lot of the federal grant money for these infrastructure projects has dried up," Coppes explained. "That means more people and communities are looking at septic systems rather than sewer systems."

“Mirel molds very well, processes in conventional injection molding equipment, and is durable in use,” said Marschand. “Add these characteristics to its biodegradability profile, and we have found a remarkable material that fits into our global corporate sustainability goals.”

The world's largest low-pressure injection molding machine, designed and constructed by Infiltrator Systems at the company's Winchester, KY, manufacturing facility, took five months to engineer and nine months to build. However, today the machine is producing the Infiltrator IM 1530 Septic Tank product line being molded in a mold designed and built by Franchino Mold and Engineering of Lansing, MI. The mold installed in the press weighs 420,000 lbs. and molds a 15-foot long, 245-lb. polypropylene tank half, which the company claims is the world's largest molded part.

The Plastics Industry Association (PLASTICS) has released final figures for NPE2024: The Plastics Show (May 6-10; Orlando) that officially make it the largest ever NPE in several key metrics.

Driven by brand owner demands and new worldwide legislation, the entire supply chain is working toward the shift to circularity, with some evidence the circular economy has already begun.

Mirel is supplied by Telles (mirelplastics.com), a joint venture of Metabolix, Inc. and Archer Daniels Midland Co. The first commercial Mirel polymer plant came on stream late last year with a design capacity of 110 million lb/yr. Mirel is available for film and sheet extrusion and thermoforming, as well as injection and blow molding. Certain grades recently received FDA clearance for food-contact applications.

Franchino has many years (16-18) of experience with building aluminum and hybrid aluminum and steel tooling for very large parts. Phillips said that some of those molds the company built have one to two million shots on them, a testament to the longevity of aluminum tooling in many large-part molding applications.

The analysis of the designs proved invaluable in accurately predicting troublespots in the design. These potential issues were identified based on the knowledge of how Mirel behaves in a mold. A principal example is the sensitivity that Mirel has to mold-filling imbalance. As with most plastics, a mold for Mirel must be designed with proper filling balance so that portions of a mold do not fill before others. In the case of Mirel, a small imbalance will lead to significant flash and/or short shots. This greatly increases scrap rates and forces a less than ideal injection molding cycle.

The world's largest low-pressure injection molding machine, designed and constructed by Infiltrator Systems at the company's Winchester, KY, manufacturing facility, took five months to engineer and nine months to build. However, today the machine is producing the Infiltrator IM 1530 Septic Tank product line being molded in a mold designed and built by Franchino Mold and Engineering of Lansing, MI. The mold installed in the press weighs 420,000 lbs. and molds a 15-foot long, 245-lb. polypropylene tank half, which the company claims is the world's largest molded part.

With Mirel it is also necessary to monitor the quality of the regrind being used. Up to 20% Mirel regrind can be used in injection molding. Typically, regrind is comprised of startup scrap and runners. Since the molds for the Paper Mate Biodegradable pens and mechanical pencils were designed with hot runners and thermal sprues, the amount of runner regrind is kept to a minimum. The regrind must still be monitored in order to ensure that it is still good material and has not been degraded. It also must be properly dried to below 0.1% moisture. (That usually takes 2 to 4 hr at 176 F in a dessicant dryer with -40 F dewpoint. Parts that contain bubbles or stick to the mold may indicate excessive moisture in the material.) The amount of regrind should be kept constant as large fluctuation in the amount or quality of regrind will affect the injection molding cycle. (Detailed processing information can be found at mirelplastics.com.)

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.

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

As part of the commercialization process for Mirel PHA bioplastics, it became necessary to validate the injection molding process for a high-profile consumer products launch. Since Mirel is a new polymer with different properties and processing characteristics, it is only natural to question the ability to use conventional tools to develop molded parts from Mirel. By partnering with a major consumer product manufacturer, we were able to explore the limits of what can be done. A new line of consumer products was designed and developed using Mirel PHA as the primary material. The process included using Autodesk Moldflow software to analyze the part filling and design of multi-cavity, hot-runner production tools. Through this process we were able to demonstrate that Mirel bioplastics can be molded similar to petroleum-based plastics.

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.

Over the years many tools have been developed to help understand, model, and optimize both the design and processing of plastics parts. Since Mirel behaves differently from conventional plastics, it is only natural to question the applicability of these tools, developed for other plastics, with Mirel. Software such as Moldflow (moldflow.com) for analyzing part and mold design and the injection molding process can be a very powerful tool to accelerate the design and development process for parts produced from Mirel. Such tools also aid in making a robustly designed part, mold, and process.
