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
This slideshow includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. Potential game-changers down the line include three microscale processes.
UL is partnering with metals additive manufacturing (AM) supplier EOS to provide AM training to EOS's customers. It's designed to promote correct usage of AM technologies by OEMs and others in manufacturing.
To commemorate Earth Day, we take a look at the state of ocean plastic. If things don't change, by 2050 the oceans will contain more plastic than fish by weight. Here are the problems, as well as some solutions.
