Magnet thermometer application in mould manufacturing industry

Thermometer application in mould manufacturing industry is particularly significant, we often use the magnet thermometer to measure thermometer on the surface of the mold. The effects of temperature on the mold is mainly manifested in the following four aspects. 1, the deformation. Stable mold temperature, cooling speed balance can reduce deformation. 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, dimensional accuracy. Use of mold temperature constant temperature control system and can reduce the products molding shrinkage rate fluctuation, improve the stability of the product dimensional accuracy. Where possible, use a lower mold temperature can reduce products molding shrinkage rate. For example, for plastic crystal form, because of lower mould temperature, the crystallinity of products is low, 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 crystal products. 3, mechanical properties. For plastic crystal shape, high crystallinity yu, the greater the stress cracking opportunities of products, so the perspective of reduce stress cracking, reduce the temperature control is good. 4, surface quality improving mold temperature can improve the surface quality of the products, low mold temperature can make the product outline is not clear and produce obvious fusion lines, and lead to product surface roughness increased.
