Disposable PVC medical nebulizer breathing mask mold,Medical product molds(Disposable medical nebulizer mask mold).
Plastic mold is a combination mold used for compression molding, extrusion molding, Injection mold processing, blow molding, and low foam molding. The coordinated changes between the convex and concave molds of the mold and the auxiliary forming system can process a series of plastic parts with different shapes and sizes.
For amorphous resins, the mold temperature is high, the solution cools slowly, the molecules have sufficient relaxation time, the crystallization trend is more complete, the crystallinity is high, and shrinkage increases. But for crystalline resins, during the entire process of professional injection molding, high mold temperature can reduce post shrinkage, making the product specifications stable.If the mold temperature is low, the cooling is fast, and the molecular structure of the solution is not relaxed enough due to the tendency of freezin…
