Rudy Koehler, Innotech president, considered the project at hand as he weighed what technology the company would utilize, including the alternatives of new two-shot molding machine or a standard press with an auxiliary injection unit. “Let’s say we have a two-shot application seven years from now, and the one that we have now goes away,” Koehler says, “and we don’t know if we’ve got the replacement work. We can take the e-Multi off; we can sell it; or we can put it on another machine.”

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

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

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.

In the Innotech molding cell, a six-axis Kuka robot inserts the metal components to be overmolded using electromagnets in the robot tooling—in the mold, pins hold them in place. Before the mold closes, cameras inspect the inserts, ensuring they’re in position and halting the cycle if they’re not.

Designed to form a component that would hold headlights in place, the mold was intended to produce a front-end automobile bracket. Instead of parts however, the tool’s real output was problems.

“Buying a pure two-barrel or two-shot machine, you’re getting into a very specific, very custom piece of equipment that might not have the versatility to run another mold in the future or be able to be reconfigured,” adds Scott Jones, Innotech’s v.p. of engineering.

Inject a substrate, insert it into a different tool and overmold—lather, rinse, repeat. For most of its 25 years, that’s how Innotech Precision Inc. in Toronto handled overmolding, using a transfer method requiring two molds, two machines and a good bit of labor input.

Discover how artifical intelligence is revolutionizing plastics processing. Hear from industry experts on the future impact of AI on your operations and envision a fully interconnected plant.

The new process has led to lower inventory, less labor, lower scrap and greater product quality. “When we do insert transfer molding,” Jones says, “we create work in process, and this totally eliminates that. The quality is a lot better. With transfer, you get into mold-fit issues with first shot into the second shot, and a lot of quality concerns. So there’s a lot of advantages to doing it this way in one machine.”

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.

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

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.

The class A trim component Innotech has been molding since mid-2020 is positioned at the front edge of the truck’s front door. Apart from the molded plastic, it comprises a stamped decorative metal element and a steel reinforcement.

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.

When a class A trim-component program for full-sized GM trucks came up in 2018, the job was not unlike many other multi-material jobs Innotech had fulfilled with transfer molding. This time, however, an advanced tool technology from a Quebec-based moldmaker and the potential to apply an e-Multi auxiliary injection unit from Mold-Masters led the company to a new overmolding strategy.

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

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.

The first shot of talc-filled PP from the main barrel encases the inserted steel reinforcement, which is located in a high-stress area of the assembly. Next, instead of a rotary table spinning the mold for the second shot, the mold has a rotating core built into it. When the platens open, the mold’s core rises out of the base and rotates 180°. The trim parts are right- and left-hand, and in the four cavity mold, the two lower cavities are filled with the first PP shot, and spun into the upper position, where the TPV seal is overmolded using the e-Multi mounted on the stationary platen.

A customer request for multi-material molding presented a market opportunity and potential financial peril: How do you add two-shot without also overextending yourself from an investment perspective?

The bigger investment and lead time on a dedicated two-shot machine would be a different story. “Maybe a pure two-shot machine has some features that we’re giving up on,” Koehler says, “but there’s enough pros to the approach we took that with 20/20 hindsight I’m still pretty comfortable with the decision.”

An articulating mold and versatile auxiliary injection unit helped this molder rethink its tried-and-true approach to insert molding.

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

The approach Innotech took was to purchase an e-Multi and a new 500-ton all-electric Toshiba press (now supplied by Shibaura Machine Co.), pairing them with a specialized multi-material mold that puts a spin on traditional 2K designs that use a rotary table.
