Due to the large variety and specifications, complex shape, and low surface roughness value, the manufacturing of molds is difficult. The deformation generated after mold heat treatment will seriously affect the quality and service life of the mold. Once it cracks during heat treatment, it will cause the mold to be scrapped. Therefore, reducing and preventing mold heat treatment deformation and avoiding its cracking is an important research topic for mold heat treatment workers. This article bri

The basic program for polishing plastic molds requires high-quality polishing tools and accessories such as oilstones, sandpaper, and diamond grinding paste to achieve high-quality polishing results.

The various tools and products we use in our daily production and daily life, ranging from the base of machine tools and the outer shell of the machine body to a small screw, button, and the outer shell of various household appliances, are all closely related to molds. The shape of the mold determines the appearance of these products, and the processing quality and accuracy of the mold also determine the quality of these products.

The working conditions of plastic molds are different from those of cold stamping molds, which generally require working at 150 ° C-200 ° C. In addition to being subjected to certain pressure, they also have to withstand the influence of temperature. Based on the different usage conditions and processing methods of plastic forming molds, the basic performance requirements of steel for plastic molds are roughly summarized as follows:

Due to the development of the plastic and plastic molding industry, the quality requirements for plastic molds are becoming increasingly high. Therefore, the issue of plastic mold failure and its influencing factors has become an important research topic.
