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 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

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.

“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.

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.

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

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.

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.”

Innotech’s goal was to automate the cell as much as possible, with one operator loading metal inserts into a nest for the robot. That same operator inspects and packs good parts within the cycle time with ample time for all three tasks.

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.

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.

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.

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

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.

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

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.

technotrans says climate protection, energy efficiency and customization will be key discussion topics at PTXPO as it displays its protemp flow 6 ultrasonic eco and the teco cs 90t 9.1 TCUs.

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.”

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