The injection molding machine screw works for a long time under high temperature, high pressure, high mechanical torque and high friction environment. The first few factors are required by the process conditions, and the loss caused by friction is inevitable. Generally, the injection molding machine screw is subjected to surface nitriding treatment to improve the […]
What is Plastic Molding? In short, plastic molding is the manufacturing process of various plastic parts. Through different plastic molding techniques, plastics can be made into plastic products with various shapes, sizes, and functions, such as: common plastic chairs, plastic cups, plastic trash cans and other daily necessities in life, so that they can be

If the plastic part shrinks unevenly, it often causes uneven distribution of internal stress. If this stress exceeds the rigidity of the plastic part, it will cause warping and deformation of the plastic part, affecting the dimensional stability of the plastic part. 1, What is warping for injection mold parts? When internal stress (due to

Start mold closing clamping 1.Starting mold clamping pressure: The initial setting value is 25. When the pressure is too low and the speed is too slow, you can try to increase the speed. If the pressure is too low and the speed cannot be increased to the required level, try adding +5 each time. Note

The screw and barrel of the injection molding machine works for a long time under high temperature, high pressure, high mechanical torque and high friction environment. The first few factors are required by the process conditions, while the loss caused by friction is inevitable. Generally, the screw and barrel is subjected to surface nitriding treatment
The plastic skin formed on the mold wall reduces the cross-sectional area of the plastic flow, resulting in a pressure drop. There is a maximum limit to the pressure that can be obtained on the injection molding machine to push the screw at the set injection speed. The pressure required to push the screw forward
