Engel demonstrates competence for multi-component technology at NPE
At NPE in Chicago, Engel, the Austrian manufacturer of injection moulding machinery part-handling automation systems, presented among other exhibits a 60 tonne tiebarless all-electric e-motion combi machine as part of an integrated system that produced a multi-component cell phone holder. The part was moulded with PP and TPE.
The traditional “in-line” injection unit injects a first shot of PP, while the secondary unit, mounting in the “L” position (vertical), injects a second shot of TPE. A fully integrated six-axis Kuka KR5 articulating robot is used for part transfer (first shot to second shot) and part removal.
The advantages of combimelt technology to the moulder are substantial, says the company:
- New part design possibilities
- Improved economics within the manufacturing process as secondary operations are eliminated
- Improved part quality (less contamination possibilities) due to a “one step” process
- In addition to design and manufacturing advantages are the specific benefits of the e-motion machine:
- Servo motor drive technology offers extraordinary precision with low energy consumption
- All-electric design provides the highest possible part repeatability
- Tiebarless design offers freely accessible mould space for minimum re-tooling times (even for bulky moulds) and easy automation
“Engel is the industry leader in multi-component injection moulding, having delivered in excess of 5,000 machines to date,” said Steve Braig, president and CEO of Engel North America.
