50 ton Chemical barrel low pressure moulding machine wholesale

Barrel Temperature - an overview | ScienceDirect Topics

The possible barrel temperature combinations available for operating the extruder are almost limitless. However, only a few temperature profiles will produce an acceptable product while providing optimum process conditions. When one knows where the polymer melts or softens, the mixing required after melting, and any downstream feeding and venting, then one can select temperature set points
