Improved performance: improved low-temperature impact performance, improved processing fluidity, improved impact resistance, enhanced heat stability of ABS
Insert molding refers to the molding method in which the mold is filled with pre-prepared inserts of different materials and then injected with resin, and the molten materials are joined with the inserts and cured to make integrated products.
Read More1. Injection molding machine
A). Excessive heating of plastic in the injection cylinder.
Lower the melt temperature.
The most important process conditions in the injection process are the temperature, pressure, speed, and the corresponding individual action time that affect the plasticizing flow and cooling.
Read MoreFor hygroscopic materials (such as nylon), high resin moisture content can also cause screw slippage. Improper drying can significantly reduce the viscosity of the material and cause the phenomenon of air-packed material in the screw, thus reducing the co

Read MoreI. Plastic moulds are generally divided into (injection moulds).
1. Two-plate mold (i.e. large spout mold)
2. Three plate mold (i.e. small spout mold, fine spout, simplified type fine spout)
Transparent plastics, because of the high light transmission rate, must require strict surface quality of plastic products, there can not be any mottling, porosity, white, haze, black spots, discoloration, poor luster and other defects, and thus the entir
Read MoreThe injection molding process of engineering plastics mainly includes three stages: preparation before molding, injection process, and post-treatment of plastic parts. The injection process generally includes several processes, such as material addition,
Read More1, mold opening, mold locking, ejector, and other actions using high-precision screw nut, transmission accuracy of 0.01mm.
2, linear guide rail, the traditional reciprocating sliding guidance into rolling guidance, improve positioning accuracy, reduce th
Vertical column-free mold locking, horizontal injection, mold open on three sides, more convenient and safer operation.
High injection pressure, torque type hydraulic motor control, high spiral torque, high pre-molding volume, system pressure controlled
Cause
1.Injection pressure or barrel temperature
2.Too much feed material
3.Too long advance time of the pump column
4.Unbalance of the feeding port in multiple writing
5.There is a depressed part in the mold
Injection molding is an engineering process that involves the transformation of plastics into useful and functional products. The important process conditions of injection molding are the temperature, pressure and corresponding work of each action that af
