NPE 2009 Wrap-Up: New Machinery for Injection Molding
New injection machinery at the show ranged from all-electric units for high-speed packaging or bioplastic processing to hybrid presses ready for the cleanroom. Other units highlighted multi-component molding with LSR and thermoplastics or super-compact presses for small parts. Several new machines targeted specific applications such as caps and closures, PET preforms, LSR, or integrated long-glass compounding.

Modular ‘Adaptable Automation’ Makes IML More Economical
Five years ago, in-mold labeling was just gaining traction among North American injection molders as a one-step approach to decorating without secondary operations.
Read MoreSequential Hard/Soft Injection Molding with Water Assist
In 2004, the value of pairing two-material injection with water assist was demonstrated in production of two-layer automotive pipes and ducts (see Learn More). Further potential for this combination of advanced techniques in sequential injection of hollow automotive parts with rigid and flexible sections is being developed at the German Institute of Plastics Processing (known as the IKV). Water injection technology (WIT) was first developed at the IKV in the 1990s.
