Temperature will affect the quality of the plastic pet dog toys?

by:Zhierde     2020-12-02
Temperature, the word we are familiar with, the proper temperature is one of the best, for example, shower, water was too cold is not good, it's too hot is not good, is the best way to moderate, it is the most comfortable, for the mold temperature to its influence is very big, proper temperature can reduce the deformation of pet toys, pet toys can he also improved the quality of the problem, and so on. The influence of the temperature on the mould quality there are a few points? Shenzhen pet toys manufacturer summarizes the following four points:





a, can reduce the deformation of pet toys


stable mold temperature, cooling speed can reduce the deformation of pet toys. Inconsistent for wall thickness and shape of complex products, often can appear due to uneven shrinkage deformation, so we must use appropriate cooling system, make mold and core basic to keep the temperature of any part of the uniform, so that the plastic melt in the cavity can be solidified at the same time.


2, can improve the surface quality of the pet toys


to improve the quality of mold temperature can improve the dongguan plastic products surface, low mold temperature can make toys outline is not clear and produce obvious fusion lines, and lead to increase of surface roughness of pet toys.


3, reducing stress cracking of pet toys


for plastic crystal shape, high crystallinity yu; Stress cracking of the greater the chance, so reduce the perspective of stress cracking, reduce the temperature control is good.


4, improve the stability of the accuracy of pet toys


using the temperature control system to maintain a constant temperature of pet toys, can reduce the pet toy molding shrinkage rate volatility, the stability of increase dimension accuracy of pet toys. Where possible, use a lower mold temperature can reduce molding shrinkage of pet toys. For example, for plastic crystal form, and, because of lower die temperature is low, the crystallinity of pet toys, lower crystallinity can reduce shrinkage. But low crystallization not conducive to the stability of the size of pet toys, starting from the stability of size, and need to raise the mold temperature, uniform crystallized pet toys.
