Injection Moulding Process The definition of injection moulding process The general injection moulding process is to feed polymer pellets or powder into the injection moulding machine via barrel, After heated, compression, shear, mixing and transmit, it gets homogeneous and melting…
Judging the Quality of Molds: Key Factors in Plastic Mold Design When it comes to assessing the quality of a mold, approximately 85% depends on the design of the plastic mold. The quality of mold design encompasses a wide range…
The successful design and fabrication of good plastic products require a combination of sound judgment and experience. Designing good products requires a knowledge of plastics that includes their advantages and disadvantages as well as some familiarity with processing methods. Until…

Injection molding is a manufacturing process for producing parts by injecting molten material into a mold. Injection molding can be performed with a wide variety of materials, including metals, alloys, glass, elastomers, and most commonly thermoplastic and thermosetting polymers. Material…
The action of the pressure holding is to continue to exert pressure to the melt plastic, in order to increase the density of plastic to compensate for the shrinkage of plastic. In the process of pressure holding, the mold cavity…
Filling stage Filling is the first step in the process of injection molding; the filling time begins from the close of the plastic mold until the 95% filling of mold cavity. In theory, the shorter the filling time is, the…
Design of branch runner Branch runner is a melt flowing way connecting the main runner and the gate, which acts as the role of diversion and turning. The branch runner system of the side gate is on the parting line…
The concept of main runner The main runner is a conical section that connects injection molding machine nozzle to the branch runner, by which the molten plastic run into the mold cavities. And its diameter is closely related to the…
The function of the mold feed system is to make the high temperature melt under high pressure go into the mold cavity to fulfill that. The style and quantity of gate and feed style often determine the specifications of plastic mold…
