Hydraulic method
The cooling medium usually uses cooling water, warm water and oil to circulate in the cooling holes to achieve the purpose of controlling the temperature.
Cooling holes should be as large as possible, but should not damage ejector pins, guide pins, mold cavities, cores, and strength.Plastic Manufacturers ， The channels of the media must also determine the order of their circulation according to the objects that exist and different conditions. In terms of flow, a large number of cycles are required to minimize the difference between liquid temperature and mold temperature.
Electric heating control method
When the mold temperature must be kept above 100 °C, electrothermal control is often used. In order to make the heater fit closely with the mold, it is usually made into special forms such as strips or rods, and the matching parts should be rust-proof.
