Engel is showcasing a new process called “Exjection” that combines injection molding and extrusion. The process allows engineers to design long thin-walled plastic profiles that integrate a variety of elements that now require expensive secondary operations. Metals parts can be inserted in the mold cavity. Films can also be applied in the tool. The new process was described at Molding 2008 by Joachim Kragl, manager of processing technology for Engel of Canada, Guelph, Ontario. During the injection cycle, the mold cavity is moved to the machine axis. At the same time, plastic is injected into the cavity.
Applications proposed for the process include:
A water drain channel out of PP with a length of 3 meters
A cable binder made of PEEK, length 1500 mm
A furniture profile with textile decoration or aluminum decor
An entrance ledge with metallic effect pigmentation
HP's industry-changing 3D printing announcement for commercial-scale end-production wasn't the only news of note at RAPID 2016 this week. Here are six more game-changing software and hardware news items, plus some videos explaining HP's technology.
HP has launched its long-heralded Multi Jet Fusion 3D printing technology for commercial-scale end-production, plus an ecosystem to go with it. The package could change the entire industrial market for making end-products with additive manufacturing. At the very least, it will be game-changing.
Nearly all the products in this latest crop of new adhesives target electronic and other components for consumer electronics and automotive assemblies. Some are alternatives to liquid adhesives, others are liquids that cure faster, and several stick well to multiple substrate materials.
