What Is A Plastic Over Moulding? The main body consists of two parts, one refers to the plastic inside and the other refers to the rubber outside. The method of overmolding, hard plastic part, is the same as that of conventional plastic mold design. For the soft rubber part, the hard plastic part is molded first, and then manually put into the plastic injection, so there is no need to apply shrink rate for
Injection mold is composed of several steel plates and various parts, basically divided into: A Forming device (female die, male die) B Positioning device (guide post, guide sleeve) C Fixing device (I-shaped plate, code mold pit) D Cooling system (water delivery hole) E Constant temperature system (heating pipe, generator) F Flow passage system (nozzle hole, flow passage groove, flow passage hole) G Ejection system (ejector pin, ejector rod) The molds can be divided into three
Factors Affecting the Quality of Precision Injection Mold in the Manufacturing Process Mold design, mold design will directly affect the quality of plastic products. Because the mold cavity size is obtained from the required size of plastic products plus the shrinkage of the materials used, and the shrinkage is often a value within the range recommended by the plastic manufacturer or engineering plastics manual, it is not only related to the mold gate form, gate
Five Steps in the Production Process of Injection Mold Injection mold manufacturing can be roughly divided into the following steps: 1、 Process analysis of plastic products. Before the mold design, the designer should fully analyze and study whether the plastic products conform to the injection molding processing principle. It is necessary to carefully negotiate with the product designer to reach a consensus. It includes the necessary discussion on the geometric shape, dimensional accuracy
