The H. F. Preheating process is widely applied for Thermo-set plastic molding such as for electric components, mechanical parts, melamine tablewares, and packaging of IC, transistors and other micro-electronic components, In the FRP pultruction and SMC/BMC molding process, H. F. Pre-heaters are also developingly used.

(1) Roller Electrode typeThis type uses special rotating electrode, achieving highly efficient heating. The roller pitch adjustment enables optimum and external temperature distribution in the preformed resin.

(2) Flat Electrode typeA variety of electrode is available for rectangle preform and powder resin.
