原创 The use of plastic molds

The use of thermosetting plastic molds to be heated when used. The most commonly used method of heating is electric heating will be electric heating element mounted on the board, or made into different shapes the electric coil assembly in the plastic moulds surface. plastic molds heating should be uniform and should be insulation to prevent heat conduction and radiation losses. The processing of different varieties of plastic molds temperature (that is, the processing temperature) are also different.
Thermoplastic plastic molds to be cooled. Especially in the injection molding process, mold cooling directly affects the plastic molding and product type, which have a direct impact on the quality of injection molding cycle and products. Commonly used thermoplastic processing temperature and mold cooling temperature see. The use of mold cooling water pipe cooling, that is, in the plastic molds or template brass pass drilling and embedded with cold water. For slender core cooling, cooling under thermal conductivity may also have recourse to law, that is, in the core in the drilling, and  plastic molds thermal conductivity of metal rod embedded in the heat derived. Uniform distribution of cooling water should be. Cooling water should be softened to prevent loss of water wall cooling effect of scale.
