Injection molding is a method of manufacturing parts by injecting materials into molds. The main method of processing plastics is injection molding. In this process, the plastic is placed into a hopper, where it is heated and injected through a long chamber with a reciprocating screw. It is then softened into a fluid state. The nozzle is located at the end of the chamber, through which the fluid plastic is forced to cool and the mold is closed. As the plastic cools and solidifies, the semi-finished product is withdrawn from the press.
Material: ABS, it can present different colors by adding different colorants. The outer layer immediately cools to form a low-density solid shell when the molten material contacts the cavity surface during molding. Due to the poor thermal conductivity of plastics, the inner layer of plastic slowly cooling and the formation of a large contraction of the high-density solid layer. Therefore, the wall thickness, slow cooling, high-density layer thickness of the shrinkage. In addition, whether or not embedded pieces and embedded pieces layout, quantity has a direct impact on the material flow direction, density distribution and the size of the shrinkage resistance, so the characteristics of plastic parts on the size of shrinkage, direction.
Injection Molding Process feature:
Resin easy to form, bending and metal rigidity, strength, and a heat resistance of the mutual combination of complementary can be made into a complex sophisticated metal plastic integration products.
Injection Molding temperature:
Low mold temperature can reduce molding shrinkage. Uniform mold temperature, short cooling time and fast injection speed can reduce the warping deformation of plastic parts. For crystalline polymers, increasing mold temperature can stabilize the size of plastic parts and avoid the post-crystallization phenomenon, but will lead to longer molding cycle and brittle plastic parts defects.
In general, the plasticizing pressure will increase the plasticizing efficiency. If the injection pressure is higher, the holding time is longer, and the product dimensional accuracy is higher.
