For injection molding of
New Car, the runner part accounts for 90% of the total volume of the object, which is generally used for large quantities of simple products with high production efficiency. However, 3D printing uses layer-by-layer printing to construct objects, which is difficult to process and has low molding efficiency. It is generally used for the production of fine products.
During the injection molding process of New Car, some abnormal phenomena are prone to occur, such as: cracks, ripples on the surface of the product, decreased brittle strength of the product, difficulty in demolding, unstable product size, unstable product size, peeling and stratification of the product, weld marks, and unsatisfied injection, etc. These phenomena will affect the specific use effect of the molding mold, so we need to find out the relevant factors and solutions.
Injection molding of New Car refers to a method of stirring completely molten plastic materials through a screw at a certain temperature, injecting them into the mold cavity with high pressure, and obtaining a molded product after cooling and solidification. This method is suitable for mass production of parts with complex shapes and is one of the important processing methods. There are mainly 6 stages: mold closing, injection, pressure holding, cooling, mold opening, and product removal.
Mechanical processing of plastics processing uses plastic processing methods such as metal and wood to manufacture plastic products with very accurate dimensions or in small quantities. It can also be used as an auxiliary process for molding, such as sawing of extruded profiles. In current production, the injection pressure of almost all injection machines is based on the pressure applied by the plunger or the top of the screw to the plastic (converted from the oil circuit pressure). The role of injection pressure in
Fuel Car injection molding is to overcome the flow resistance of plastic from the barrel to the cavity, give the melt filling rate and compact the melt.
