Many people do not know about the injection molding process, but they are curious and interested in it. Xiaobian is also the same, in the process of some very interested, let HUIWEN Xiaobian for you to unveil the veil of the injection molding process.
HUIWEN unveils the injection molding process for you
The injection molding process of plastic parts mainly includes six stages: closing - filling - (air - assisted, water - assisted) pressure - cooling - mold - stripping.
1. Closing the mold: that is, closing the mold
2. Filling: filling is the first step in the whole injection cycle. The time is calculated from the beginning of the injection of the mold closure to the filling of the mold cavity to about 95%.
3. Pressure retention: The role of the pressure retention stage is to continuously apply pressure, compress the melt, and increase the density of plastic (densification) to compensate for the shrinkage behavior of plastic.
4, cooling: molding plastic products only cooling and curing to more rigid, demolding can avoid plastic products due to external force deformation.
5. Mold opening: open the mold.
6. Demoulding: Improper demoulding method may lead to uneven force during demoulding and deformation of the product when it is ejected. When designing the mold, the appropriate demoulding method should be selected according to the structural characteristics of the product to ensure the quality of the product.
