Cylinder Design Eliminates Need for Water Cooling Actuators

The new HRScool cylinder design from HRSflow eliminates the need for water cooling of the corresponding actuator due to the twice optimized temperature management system. This system includes insulating supporting columns with a minimal contact surface, reducing the input of heat from the hot runner to the cylinder housing. It includes a cover with a large, flat surface made of thermally conductive material. The integrated telescopic design enables maximum heat dissipation from the cylinder to the cold platen.

Since HRScool eliminates the need for elements such as cooling lines, channels and connections, assembly and handling costs are reduced, problems with clogged cooling circuits and hydraulic fluids degradation are decreased, machine availability increases and operating costs are lowered. The system’s compact design takes up less space in the molding tool, resulting in an optimum uniform temperature distribution along the entire hot runner system and achieving higher molding quality. With the bayonet coupling, the valve pin can remain in the hot runner system when cylinders need to be removed.
