Mold temperature refers to the mold cavity surface temperature in contact with the product during injection molding. Because it directly affects the cooling rate of the product in the mold cavity, and thus has a great influence on the intrinsic performance and appearance quality of the product. In this paper, five points of influence of mold temperature on quality control of injection parts are discussed. The content of the package material system for excellent products is adopted for friends' reference

the plastic processing industry is quite vigorous, with the continuous progress of material technology, the injection molding process is now more and more mature, many manufacturers have been able to master this technology to produce and process plastics. In the middle of the injection molding process, the demand is often applied to a few molds, and the quality of the mold simply affects the quality of plastic products to some extent, so for the operator, the application of the tube mold is the basic requirement. What events do you need to pay attention to in the middle of the application process of injection molds?

When turning a slender shaft, due to the poor rigidity of the workpiece, several shapes of the turning tool have obvious influence on the vibration of the workpiece. The following points are mainly considered in the reasonable choice of geometric Angle of the CNC turning and milling compound machine tool:

How to control the temperature during injection molding？

Die processing refers to the processing of forming and blanking tools, including die-cutting dies and shearing dies. Usually the mold consists of an upper mold and a lower mold, the material is formed under the action of the press, and the steel plate is placed between the upper mold and the lower mold. When the press is opened, the workpiece determined by the shape of the die is obtained or the corresponding scrap is removed. Workpieces as large as car dashboards and as small as electronic connectors can be molded with molds. A progressive die refers to a set of molds that can automatically move the processed workpiece from one station to another, and obtain molded parts at the latter station. Die processing technology includes: four-slide die, extrusion die, compound die, blanking die, progressive die, stamping die, die-cutting die, etc.

The polyurethane sealing ring should have good sealing performance within the working pressure and a certain temperature range
