What is the effect of temperature on foshan puzzle toys
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 products, but also can improve the quality of products and so on.
The influence of the temperature on the mould quality there are a few points?
Summarizes the following four points: foshan puzzle toy manufacturers, can reduce the deformation of foshan jigsaw stable mold temperature, cooling speed reduces the deformation of the product.
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.
Second, can improve the surface quality of the products mold temperature can improve surface quality of the foshan jigsaw puzzle, low mold temperature can make the products outline is not clear and produce obvious fusion lines, and lead to product surface roughness increased.
Three, reducing stress cracking of mould 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.
Four, improve the stability of the foshan jigsaw puzzle size accuracy use mold temperature of constant temperature control system and can reduce the foshan puzzle toy molding shrinkage rate fluctuation, improve the stability of the foshan jigsaw puzzle size accuracy.
Where possible, use a lower mold temperature can reduce foshan molding shrinkage ratio of jigsaw puzzle.
For example, for plastic crystal form, and because the mold temperature is low, low, the crystallinity of foshan puzzle toys, lower crystallinity can reduce shrinkage.
But low crystallization is not conducive to the stability of the products size, from the stability of size, and need to raise the mold temperature, uniform foshan jigsaw crystallization.
