Characteristics of Gas Assisted Injection Molding and Injection Molding

Characteristics of Gas Assisted Injection Molding and Injection Molding

The characteristics of gas assisted injection molding and injection molding are that the general injection molding method requires the wall thickness of the plastic part to be as uniform as possible, otherwise defects such as shrinkage holes and depressions may occur at the wall thickness. For thick wall crabs, Dongguan Machike Injection Molding Plant needs to strengthen the pressure maintaining and feeding time in order to prevent depression. However, if the thick wall is far away from the gate, even if the pressure is excessively maintained, it is often difficult to work. At the same time, due to excessive pressure retention near the gate, residual stress increases, which can easily cause warping, deformation, or cracking of the crab parts. Foreign countries have adopted a new process of gas assisted injection molding, which effectively solves the injection molding problems of plastic parts with uneven wall thickness and hollow shells. In addition, gas assisted injection molding has other characteristics. At present, the new process of gas assisted injection molding and injection molding is gradually being promoted and applied.

UV treatment for surface treatment of plastic injection molded parts

UV treatment for surface treatment of plastic injection molded parts

UV treatment is a surface treatment process for plastic injection molded parts. Generally, after UV treatment, the surface of plastic injection molded parts can have a brighter surface effect and are not easily scratched. The main process is to spray a layer of transparent oil on the surface, which needs to be dried by ultraviolet light. Below, we will explain what to pay attention to when UV treatment is applied to plastic injection molded parts:

Discussion on uneven gloss of plastic mold products

Discussion on uneven gloss of plastic mold products

Due to poor distribution of pigments or fillers, the color of plastic or pigment discoloration on the surface of plastic parts is uneven. The reasons for uneven color vary depending on the phenomenon presented. The uneven distribution of pigments near the feeding port is mainly caused by poor thermal stability of the plastic when the color of the entire plastic part is uneven, and the uneven color of the fusion joint is related to the properties of the pigments.

Nine major development trends presented by the domestic and foreign automotive mold industry

Nine major development trends presented by the domestic and foreign automotive mold industry

The three-dimensional design of molds is an important aspect of digital mold technology and the foundation for achieving the integration of mold design, manufacturing, and inspection. Japanese companies such as Toyota and General Motors have achieved 3D design of molds and achieved good application results. Some practices adopted in 3D mold design abroad are worth learning from. In addition to facilitating integrated manufacturing, the three-dimensional design of molds also has the advantage of facilitating interference inspection, allowing for motion interference analysis, and solving a difficult problem in two-dimensional design.
