Mold-Masters has extended the capabilities of its E-Multi auxiliary injection platform, introducing the new larger capacity EM5 model.

Made for a well-known American industrial tool brand, the plastic bumper component is a decorative and functional all-plastic part assembled onto a large, rolling, automotive mechanic toolbox cart. Featuring high finish and surface quality requirements, the bumper is roughly three feet in length, and incorporates two colors and clean shutoffs for a crisp, sharp imprint of the company brand, including the trademark icon. The design calls for red nylon 6/6 substrate to be overmolded with soft TPU in a 2+2 mold, with the black rubber framing the red logo.

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

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.

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.

Like Core, the customer is based in the Southeast — a region wanting when it comes to molders with 2-shot capabilities in the medium tonnage range (which is one reason Core got into multimaterial molding back in 2019). Core has a lot of exposure and expertise in automotive but serves a variety of markets beyond that, including medical, packaging and outdoor power equipment, among others.

In addition to efficiency, Core said lead time and total cost helped make the case for the EM5. When quoting a dedicated 2K injection molding machine with a rotary table, Core was given lead times of 50 to 52 weeks, compared to 14-16 weeks for the EM5, which was slightly less than the quoted mold-build time for the job, creating a scenario where the EM5 could be installed and ready for the new tool to start production on day 1.

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.

One of the first to utilize Mold-Masters’ newest, largest auxiliary injection units —the E-Multi 5 (EM5) — Core Technology Molding Corp., Greensboro, North Carolina, was able to produce a 2-shot “bumper” component for a rolling toolbox cart four times faster and at half the cost compared to the prior production setup. “The previous process couldn’t make sellable parts in the same day,” explains Brandon Frederick, Core’s engineering manager. “Prior production had two different processes, two different tools and two operators. We’re half the cost — we didn’t need two machines.”

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

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.

“The logo aspect,” Frederick says, “that’s everything to the customer, and it’s really precision molding at that point. This is not a shoot-and-ship part, that’s an A surface, and we have to make sure our process is robust.”

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.

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?

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.

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.

The EM5 was used to inject the red nylon 6/6 substrate while the black overmolded rubber was injected by the machine’s primary injection unit. In the design, the EM5 injected 864 g for the nylon 6/6 substrate, while the machine’s primary injection unit delivered the 800-g TPU overmold with a total cycle time of 70 seconds for the 2+2 mold. Normally, Frederick notes that the auxiliary unit would handle the rubber overmolding, but because the nylon 6/6 could degrade if the residence time was too long, Core utilized the EM5’s smaller barrel and shot size for the nylon. Shot sizes for the EM5 range from 550 to 1,200 g, says Dave Silva, Mold-Masters’ director of product development.

Wittmann Battenfeld will introduce the new EcoPower B8X injection molding machine line and show direct current as an energy source for a concept machine that will power its own robot.

The biggest advantage for Core in shifting this production to two-shot versus insertion and overmolding was staffing. “The biggest piece is the labor aspect,” Frederick says. “You go from taking molded substrates and placing them in the tool, dedicating half an operator for just putting parts into boxes, to now where machines do all the work in one press with one mold.”

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.

The EM5 is attached to the molding machine in an L-shaped configuration on the non-operator side of the press with an injection point on the hot half, stationary half of the tool. E-Multi’s can be installed vertically, horizontally or at any custom angle to accommodate the cell. Freise says that due to the EM5’s size, Mold-Masters expect most of its installs will be horizontal.

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.
