Injection molding and blow molding Sep 18, 2019
Plastic molding is a process in which a synthetic resin is used to make a final plastic product. Processing methods include: compression molding (molding), extrusion (extrusion), injection molding (injection molding), and blow molding (hollow molding). Let's distinguish between the molding process of injection molding and blow molding. (1) Injection molding: Injection molding is a method in which ...

What is venting defective of product? Aug 19, 2019
When the injection machine starts to molding，the hot melt plastic flows in the mold cavity and squeezes the air in the mold cavity. If the air cannot be discharged effectively, it will cause venting, and the result will be that the product is short-shot or affects the quality. Under this situation, We need to check the injection speed, the mold temperature, Or add venting groove.

Plastic injection product defects discussion Sep 18, 2019
Today we are going to discuss common defects for plastic injection products. 1. Short shot The plastic part is insufficiently filled (or the injection pressure is not enough, the mold nozzle is too small). 2. Ejector Mark The part is poorly released or the ejector pressure is too high. White marks and bumps appear on the surface of the product: 3. Flow marks: The Part is not slippery, ...

Splay Mark of Plastic Products Sep 17, 2019
Splay mark is a normal problem during manufacture plastic products. There are a few reason cause this problem: 1. The material contains water, drying time is insufficient. 2. Weld back pressure is too small or no back pressure. 3. Venting is not so good. We need keep to drying the material, Increasing back pressure, Improving the mould venting.
