Key Points for New Mold Test About new mold test 1. Test steps A. Before testing the mold, check whether the mold is assembled and whether the raw materials are dried. B. Before changing the mold, spray the mold with anti-rust agent. Then, replace the mold and return to its position. Finally, fill in the record form. … Read more
About the shortcomings of injection molded parts 1. Description of shortcomings It refers to the injection molded parts that cannot meet the quality requirements of the original design and use during the injection molding process. A possible cause may be included when describing the shortcomings. For example, insufficient injection molding, that is, incomplete injection molding. It may be … Read more
The Main Plastic Properties Related to Injection Molding Processing The Main Plastic Properties 1. Liquidity The ability of the plastic in the molten state after being heated to fill the entire cavity under pressure is called fluidity. And it is generally tested with a professional fluidity test mold. The fluidity of plastics of the different … Read more
Light Line in the Gate Area of the Injection Molded Product In the point gate design of the vertical part direction, a radiation system appears on the surface of the part during injection molding. It’s composed of different color depths and glosses and it centers on the gate. And we call it the light line. … Read more
Application and Process of Gas-assisted Injection Molding 1. The principle of gas-assisted injection molding High-pressure inert gas (nitrogen) is injected into the molten plastic to form a vacuum section and push the molten material forward. And that finally realizes the processes of injection, pressure holding and cooling. Due to the efficient pressure transmission of the gas, the pressure in … Read more
5 Effects of Mold Temperature on Quality Control of Injection Molded Parts Mold temperature refers to the surface temperature of the mold cavity in contact with the product during the injection molding process. Because it directly affects the cooling rate of the product in the mold cavity. And that has a great impact on the … Read more
The Processing Principle of Gas-assisted Injection Molding System The gas-assisted injection molding system directly injects nitrogen into the plasticized plastic in the mold cavity through a segmented pressure control system. Then, the inside of the plastic part expands and becomes hollow. But it still keeps the shape of the product surface intact. Advantages of applying … Read more
About the Design of Gas-assisted Injection Products Gas-assisted injection molding technology is an emerging plastic injection molding technology. Its principle is to use high-pressure gas to produce a hollow section inside the plastic part. And use gas pressure to replace plastic injection pressure to eliminate product sink marks and complete the injection molding process. The gas-assisted … Read more
