What plastic materials need to be dried for injection molding products?.. How much is the temperature?
This is closely related to the temperature and the drying time, can also lower, then bake it for a long time, high temperature, can reduce the drying time, as long as the product does not appear to be silver, you should also work out rules according to the plastic particle type, saving energy, in line with the actual situation, and formulate a in order to control the process indexes.
Plastic particles should be drying, remove moisture, in order to achieve this goal, generally should be drying temperature control at more than 100 degrees, but should be less than plastic (plastic varieties related) softening temperature.
Plastic particles, such as water, are evaporated in the pre heating process of the injection molding machine and then condensed in the cooling molding process, which acts as (Yin Si) in the product and affects the quality of the product.
