Iberia, Ohio — Yizumi-HPM Corp., the U.S. unit of Chinese injection press maker Guangdong Yizumi Precision Machinery Co. Ltd., showed three new injection molding machines at an open house Oct. 30, including the Iberia operation's first packaging machine.
The parent company has been offering machines targeting thin-wall packaging for about five years, but the new PAC-K press is the North American version of Yizumi's packaging press, said Bill Duff, general manager of sales and marketing for Yizumi-HPM.
"It's a new market segment for packaging," Duff said. "We're not going after the Netstal business or the Husky business in PET. But it's a machine that could be used in a lot of applications for certain types of thin-wall containers — food containers, yogurt cups, butter dishes, cutlery. And it's very economically priced."
The servo-hydraulic PAC-K presses are available in three clamping-forces, of 275, 385 and 500 tons. At the open house, a 385-ton press molded yogurt cups on an eight-cavity mold. The cycle time was just under three seconds, Duff said.
Available shot sizes run from 7 ounces to 24 ounces.
The high-speed clamping unit uses a negative-angle toggle design, which Duff said is a faster toggle designed for thin-wall packaging. A standard toggle opens up squarely, fixing the crosshead at 90 degrees to form a "T," he said. In the negative-angle toggle arrangement, the angle is back a little bit.
"It's a little bit quicker, smoother operation and it has better mold protect," Duff said at the open house. The PAC-K also has linear bearing guides and no tie-bar bushings. Ultra-rigid platens have minimal defection.
The standard PAC-K has fast injection, good for cycles in the five-second range, but Duff said the machine can reach injection very fast speeds up to 585 millimeters a second by equipping the press with accumulators. "It all depends on the application," he said.
Yizumi-HPM opened its headquarters in Iberia, a tiny rural town in Morrow County, Ohio, in 2017, six years after Guangdong Yizumi Precision Machinery bought the intellectual property of HPM during an auction at the shuttered machinery factory in nearby Mount Gilead, Ohio. Yizumi initially leased the former HPM Remanufacturing building in Marion, Ohio, then opened the Iberia operation.
Last year the company announced it would expand the 22,000-square-foot technical center by building an addition.
Yizumi-HPM also rolled out a new two-platen multimaterial injection molding machine, the DP-N Multi-Pro, and a hybrid hydraulic and electric machine called the FF-N.
