Cm-w series water mold temperature controller is mainly used for mold heating and constant temperature. In addition, it can also be applied to other fields with the same requirements. This series of mould warming machine is directly cooled by the return water of the mould, then pressurized by the pump, heated by the electric heating tube at high temperature, and then sent to the mould to meet the requirements of heating and constant temperature. The optimized design makes the heating temperature reach ± 120 ℃. P.i.d temperature control is adopted to ensure high-performance stable temperature control, and the temperature difference can be controlled at 1 ℃.
