2018-10-09Main factors affecting precision injection molding
Precision injection molding is determined on the basis of the accuracy of the injection products, namely, product size tolerance, shape and position tolerance and surface roughness. Precision injection molding must have many related conditions, and the most essential is the plastic material, injecti....
2018-10-09Composition of injection mold
Although the structure of the mold may vary greatly due to the variety and performance of plastics, the shape and structure of plastic products and the type of injection machine, the basic structure is the same. The mold is mainly made up of gating system, tempering system, molding parts and structu....
2018-10-09Basic classification of injection moulds
Injection mold can be divided into thermosetting plastic mold and thermoplastic plastic plastic mold according to molding characteristics; injection mold can be divided into transfer mold, blow mold, casting mold, thermoforming mold, hot-pressing mold (compression mold), injection mold and so on acc....
2018-10-08Relationship between injection moulds
1.Heat is transferred to the atmosphere and mould frame through thermal radiation. The heat absorbed by the heat conducting fluid is taken away by the mold temperature machine. The thermal balance of the die can be described as: P=Pm-Ps. The P is the heat that is taken away from the mold, Pm is the ....
