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
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
As we saw on the show floor this week at the Pacific Design & Manufacturing and co-located events in Anaheim, Calif., 3D printing is contributing to distributed manufacturing and being reinvented by engineers for their own needs. Meanwhile, new fasteners are appearing for wearable consumer and medical devices and Baxter Robot has another software upgrade.
