What are the characteristics of plastic mold ABS injection molding process
ABS, commonly known as acrylonitrile butadiene styrene, is made by copolymerizing three monomers of acrylonitrile-butadiene-styrene. Due to the different ratios of the three monomers, they can have different properties and melting temperatures. If ABS with fluidity is blended with other plastics or additives, it can be expanded to ABS with different uses and properties, such as impact resistance and heat resistance. , Flame retardant, transparent, reinforced, electroplating, etc.

What is the difference between mold injection processing and blow molding processing
The process of injection molding and blow molding is different. Blow molding is injection + blowing; injection molding is injection + pressing; blow molding must have the head left by the blowpipe, and injection molding must have Gate section.

How to deal with warpage and deformation of plastic molds during injection molding
Warpage and deformation of plastic injection molded products is a very troublesome problem. It should be dealt with mainly from the aspect of mold planning, while the adjustment effect of molding conditions is very limited. So, how do we deal with the warpage and deformation of plastic injection molded products?

What are the injection molding processes that affect the strength of injection molded parts
Nylon and POM materials are all crystalline plastics. The mold is injected with hot oil by a hot oil machine, which can slow down the cooling rate of the injection molded part and improve the crystallinity of the plastic. At the same time, due to the slowing down of the cooling rate, the residual internal stress of the injection molded part is also reduced. Therefore, the impact resistance and tensile strength of nylon and POM parts injected with hot oil in a hot oil machine will be improved accordingly.
