The information is reviewed and updated continuously.

Processing stages PRESSURE PROFILE Compact Molding Structured Foam Molding Cycle Time Pr es su re The main reason for the use of Hydrocerol Chemical Foaming Agents is to achieve weight reduction of plastic parts, which in turn saves material costs and supports a more sustainable profile to the molded part. This is especially evident in molding systems, which utilize gas counterpressure systems on the mold, to keep maximum pressure on the melt front during the filling stage. PHASE 2: FILLING AND EXPANDING In this stage, either a rapid injection is used to keep pressure on the melt, or a slower injection (to minimize turbulence) if a gas counterpressure system is utilized.

We will review our long-term growth drivers and the mega trends that support them.
