1. The cavity and core are three-dimensional of Plastic Electrical Mold 

The external and internal shapes of plastic parts are directly formed by the cavity and core. It is difficult to process these complex three-dimensional surfaces, especially for the processing of the blind hole internal molding surface of the cavity. If the traditional processing method is used, it requires not only high technical level of workers, more auxiliary tools and tools, but also long processing cycle.china Plastic Electrical Mold.Customized Precision Mold Parts manufacturer and supplier

2. High Precision Mold Parts  and surface quality are required, and long service life is required.

At present,  plastic electrical mold the dimensional accuracy requirement of general plastic parts is IT6-7, and the surface roughness is Ra0.2-0.1 μ m. The dimensional accuracy of the corresponding injection mold parts is required to reach IT5-6, and the surface roughness is Ra0.1 μ Below m. The roughness of the recording surface of the laser disk should reach 0.02-0.01 of the level of mirror processing μ M This requires the surface roughness of the mold to reach 0.01 μ Below m.

Long-life injection mold is necessary to improve efficiency and reduce costs. At present, the service life of injection mold generally requires more than 1 million times. The precision injection mold should use a rigid mold base, increase the thickness of the template, and add supporting columns or conical positioning elements to prevent the mold from deformation after being pressed. Sometimes the internal pressure can reach 100MPa.Plastic Electrical Mold.presision core parts.

Ejection device is an important factor that affects the deformation and dimensional accuracy of products, so the best ejection point should be selected to ensure uniform demoulding. The structure of high-precision injection mold mostly adopts inlay or full assembly structure, which requires that the processing accuracy and interchangeability of mold parts are greatly improved.presision mold parts.
