Ready to Get Serious About Energy Efficiency?
Once upon a time, it was hard to get plastics processors to give more than lip service to the idea of conserving energy in their plants.

Sequential 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.

Read MoreMaking History in Aachen
Aachen, Germany, is a very old city. The Romans enjoyed its hot springs, and Charlemagne made it the capital of his new Holy Roman Empire in 800 A.D. The cathedral, or Dom, once Charlemagne鈥檚 private chapel, dates from that era. Since 1950, Aachen has been making history in plastics processing, as well.
Read More'Jet-less' High-Pressure Mixhead Reduces Cost and Complexity
A radically new design for high-pressure polyurethane mixing heads is said to apply a more efficient mixing concept that requires lower pressures and thereby simplifies system design. It eliminates the usual internal jets, thereby reducing the level of operator skill needed for flow adjustments and permitting a wider range of flow rates.
