Water channel manifold is used to cool plastic injection machines. It has multiple port designs (2 in 2 out ~ 12 in 12 out) and can be selected according to mold size and cooling requirements. Its functions can be divided into perspective type and simple type. The perspective type is equipped with a float indicating flow meter, which can clearly understand the flow of coolant from the position of the float. In addition, a thermometer can be installed at the outlet (CCSK type) to understand the temperature of the return water.
