Exploiting tiebarless machines for award-winning molding projects


Electric tool housings, espresso machine coffee capsules, and fuel filler door module components: work on those eclectic applications that exploit Engel's tiebarless injection molding machine series were honored by the Austrian machine manufacturer on June 13 as part of its Technology Symposium in Linz. The Engel HL Awards 2012, presented on June 13, were extended to automotive OEM Volkswagen (Wolfsburg, Germany); Italian molder/moldmaker O.C.S.A. (Creazzo); and Hungarian injection molder Anton (Zalaegerszeg).

Engel says its tiebarless technology, which it introduced to its victory series of machines more than 20 years ago, supports efficient production concepts, but also "inspires more and more users to develop totally new process ideas." To wit, in 2012 the company had to consider 25 projects from 15 countries for its HL Awards.

From those, Volkswagen won the gold for fuel filler door modules for the Golf, Golf Estate and Golf Plus models. Engel noted that the project's large tools utilize the entire platen surface and actually protrude beyond at the sides. Grippers on the handling robot can reach into the mold space, and both of these factors ensure that the production cell has a minimal footprint. Free access for the robots also reduces cycle time. A victory 750/400 molds the 30%-glass-filled polypropylene filler doors, with a Kuka multiaxis robot transferring that part to a victory 1050/400 tech for overmolding of an EPDM seal.
