The oil-type mold temperature control machine series includes standard type, high-temperature type and dual-temperature type, mainly used to control mold temperature and keep the mold temperature at a constant state. Using oil as heat transfer medium, it achieves heat exchange through indirect cooling. The mold return oil is indirectly cooled through the cooler, then pressurized by the pump and heated by the electric heating tube before being sent to the mold, meeting the requirements of heating and temperature control. It has advantages of wide temperature control range and good thermal stability.
