What are the effects of plastic mold temperature on injection molding?

(1) The purpose and function of temperature control on formability
The appearance of the formed product, physical properties of the material, and forming cycle are significantly affected by the temperature of the mold core. In general, the temperature of the mold core is kept low during molding, and plastic mold processing can increase the number of shots. However, the forming cycle related to the shape of the formed product (mold core structure) and the type of finished material also depends on the need to increase the temperature of mold core filling.
(2) To prevent stress, temperature control is applied
This is a material issue with the formed product, and the only requirement for this is ※ cooling speed. The cooling time is short, and even in situations where some parts are hardened and some parts are still soft, it can still avoid stress caused by uneven shrinkage. Proper temperature control can improve the cooling stress properties.
(3) Temperature control for adjusting the degree of crystallization of forming materials
Crystalline materials such as polysulfide (nylon), polyacetate ester, and polypropylene generally require a higher mold core temperature to regulate the degree of crystallization and improve mechanical properties.
