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…
