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

According to Daniel, injection molding machines are not limited to always using the Shuttle Mold system on machines equipped with it. If, for example, a company needs to run other molds on the machine and does not wish to use the shuttle function, it is perfectly capable of operating as a standard single-mold machine. “It does not hold your machine captive,” he says.

Instead of letting cooling time be wasted time, the Shuttle Mold System from Canon Virginia enables molders to inject a second mold while the part in the first mold cools.

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.

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.

When cooling times are around 30 seconds, the Shuttle Mold can start showing productivity improvements over a single-mold process. Under the right conditions, Canon Virginia can effectively double the production rate, as this chart shows.

Prolonging tooling service life is of paramount importance for any moulding project since downtime for repairs jeopardises profit margins. According to estimates, around EUR 10 billion are spent each year for maintenance operations worldwide. During the moulding process, the friction forces developed between the closing surface and those contacting the injected plastic largely account for the damage caused to the surfaces. Ultimately, the mould needs to be scrapped. Put together, these significantly affect the mould’s service life. The EU-funded cleanMOULD project demonstrated novel coatings based on a multilayer diamond-like carbon formulation that prolong the life of injection moulding tools, offering corrosion protection, reduced wear and resistance to friction. “Importantly, our novel coating solutions increase mould performance and extend its operation before the need to take it out of service for preventive maintenance,” reports project coordinator Michael Hvam.

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.

Canon Virginia is actively involved in supporting its customers, working with them to develop processes and providing support. “We developed this system to improve the cost and efficiency of producing inkjet printer parts in-house,” Daniel says. “It started out with an end-user focus because we are end users.”

The Shuttle Mold system enables users to inject parts in two molds with a single injector, turning cooling time for one part into productive time for another.

Gifted with extraordinary technical know how and an authoritative yet plain English writing style, in this collection of articles Fattori offers his insights on a variety of molding-related topics that are bound to make your days on the production floor go a little bit better.

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.

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

According to Canon Virginia Director of Business Development Wayne Daniel, this process came about after Canon started changing how they thought of cooling time. While common practice treats any time spent cooling as time wasted, the company recognized that there were diminishing returns with that approach. “It’s a known fact that molded parts have to have cooling time, whether it’s short or long,” he says. “Instead of reducing it, we asked ourselves how we can utilize it.”

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.

Depending on the process, the Shuttle Mold can improve efficiency as much as 200%. “It’s not a fit for every process,” Daniel says, “as it relies on a cooling time long enough to accommodate an additional injection.” Smaller injection molding machines and parts with short cooling times simply do not see as much benefit as parts more suited to the process. “Once you get to 30-second cycle times, the Shuttle Mold can start showing productivity improvements over a single-mold process,” says Daniel. “Once we can effectively double the production over a single mold, we can hit 200% efficiency.”

A new low-friction, high-hardness coating is poised to expand the range of surface treatments to help tooling stand up to tough moulding challenges. The new diamond-like coating can increase the mould service life by up to 10 times compared to the state of the art.

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

While the concept is simple, the engineering that went into making the Shuttle Mold is advanced. “It requires integration with the machine maker, including both the physical shuttle and the software,” Daniel says. “However, it can work with any molding machine that can be easily upgraded.”

Telephones, PC parts, toys, electrical plugs, and other everyday products like shoes and pens are made with plastics using a process called injection moulding. The technology can produce identical parts at high volumes at a low cost per part. However, its start-up cost is relatively high, mainly because custom tooling is needed. An injection mould can cost anywhere between EUR 100 000 and EUR 300 000, depending on its complexity, material and accuracy.

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.

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.

While the tooling is quite like a standard injection mold, the mold base needs to meet certain conditions to work with the rollers that shuttle the molds into position. “This is not a problem for new molds,” Daniel says, “as this can be incorporated in the tool design. It does mean reworking existing molds, however.” Other modifications are relatively minor such as relocating existing water and electrical connections.

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

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 Shuttle Mold System from Canon Virginia relies on a simple premise: Rather than waiting for the part to cool before beginning a new cycle, the system runs two separate molds in a single press simultaneously. The process begins with the system injecting plastic into the first mold, which the system then unclamps and moves the mold out of position as it shuttles the second mold into place. As the part in the first mold cools outside the machine, the system clamps the second mold into place and injects the plastic into it. Finally, the system unclamps and moves the second mold out of position, bringing the first mold back into place where it can eject its part and restart the cycle.

The Shuttle Mold System from Canon Virginia allows a molder to turn cooling time into productive time. The system enables the injector to make parts in a second mold while the part in the first mold cools.

A key attribute of the diamond-like carbon coatings is the ability to resist wear by lowering the friction between sliding surfaces. This largely eliminates the need for surface lubrication and post-finishing, which are deemed primary sources of pollutant releases to the atmosphere for certain industries such as pharmaceutical and food. The coatings are applied using a physical vapour deposition process called magnetron sputtering at temperatures as low as 180 °C. Due to this advanced deposition process, the diamond-like carbon coatings can maintain a very thin, uniform finish (1-5 μm) over the entire mould independently of its geometry. “cleanMOULD’s novel coatings optimise both surface hardness and lubricity to minimise the impact of fretting,” notes Hvam. The high hardness of the newly demonstrated diamond-like carbon coatings, which are 8 times harder compared to other coatings, allows the surfaces to become more resistant to scratches that occur during operation. It goes without saying that the absence of oil lubricants makes mould cleaning much easier: it only requires applying ethanol to a cloth for less than 10 minutes. cleanMOULD’s ‘mould breaking’ has the potential to become a key enabling technology for the entire plastics industry. Overall, the return on investment for cleanMOULD users is expected to be over 20 times the expected coating costs, thus providing a compelling value proposition. Pilot-test results demonstrated a sixfold decrease in the maintenance interval compared to state-of-the-art coatings. No fretting corrosion has been observed on any coated moulds. What’s more, “cleanMOULD’s coating demonstrated a decrease in the moulding cycle time of screw lids from 40 to 36 seconds, which is equivalent to an 11 % increase in productivity,” concludes Hvam.

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

Additionally, the cost savings the Shuttle Mold System provides are exceptional. Compared to the cost of buying two separate machines, including dryers and other auxiliary equipment, purchasing a single machine with the capacity of two provides excellent savings. “You can double your production speed for one part,” Daniel says, “or you can produce two different parts with a single machine. Both options save you a lot of money in the long run.”

Since the first public demonstration at the 2018 National Plastics Expo, Canon Virginia has seen interest in its system grow. “At first, we sometimes see resistance to the idea, as it runs counter to the philosophy most molders work by,” Daniel says. “But shaving a few seconds off of cooling, or even cutting cooling time in half just isn’t as efficient as working straight through the cooling cycle.”

Every injection molding machine knows cooling time is lost productivity. They spend hours of engineering time and thousands of dollars just to shave a few seconds off a cycle. Unfortunately, improvements to cooling time necessarily bottom out. There is simply no way around the fact that plastic must cool down before it can come out of the mold, and you can only reduce cooling time so much before you run into issues affecting part dimensions and physical properties.

Faced with this reality, one company decided that instead of making cooling time shorter, it would turn this lost time into production time. To do this, Canon Virginia uses a shuttle system to switch between two molds using a single injection molding machine. Because they can simultaneously mold two parts at the same time, total part cycle time can be dramatically reduced which the available capacity of the molding machine goes up significantly. Here’s how they do it.
