Equipped for Molding High Performance Polymers
Arburg and Welltec injection molding machines, with Bosch hydraulic valves, Intermot high torque motors, nitrate hardened alloy screws and barrels, and ceramic heater bands, develop pressures and speeds 40% higher than others in their class. Xaloy screw/barrel assemblies are used for specialized applications.
Wittmann oil mold temperature controllers maximize cycle effectiveness. Matsui desiccant resin dryers (shown at left) prepare resins to tight drying tolerances, which are measured with a Sartorius-Omnimark moisture analyzer down to 500 ppm.
