Injection molding, also known as injection molding, is a method of molding by injection and molding. Stirring the completely molten plastic material by a screw at a certain temperature, injecting the plastic material into a mold cavity of a mold at a high pressure, and cooling and solidifying the plastic material to obtain a molded product.

How to shorten the molding cycle of injection molding and further improve the production efficiency is a subject of research by people in the injection molding industry. Since the heating and cooling ratio of the mold is the largest in the whole molding cycle, how to cool and heat the mold quickly becomes the most effective method for shortening the molding cycle.

If the mold core of the mold is directly heated, the temperature of the mold core is higher than that of the mold frame based on the principle of expansion with heat and contraction with cold.
