With the rapid development of my country's economy, the application of injection molds in various industries has become more and more mature. Many plastic parts of products need to use injection molds, and the quality and service life of injection molds affect the production cost of enterprises. Therefore, it is very important to improve the quality and maintenance of injection molds to improve the service life of injection molds. So what factors will affect the quality of injection molds and how to maintain injection molds?
Injection molds will affect the final injection mold quality in terms of raw materials, design, processing technology, etc. The specific manifestations are as follows: 1. Mould steel Steel is the decisive factor of mold quality, and choosing a reasonable steel is the top priority. The criteria for selecting steel are: ①Requirements for injection molding materialsDifferent plastics should use different steels, such as high polishing requirements, corrosion resistance requirements, etc.; ②PriceThe steel can be used as long as it is more expensive; considering the cost factor of the mold, the mold steel should be selected corresponding to the mold life to prevent unnecessary waste; the life of the general P20 material is about 300,000; 2738 There is no problem if the data is 500,000, H13/2344 is usually more than 800,000-1 million, which can be selected according to the situation; ③Appearance treatmentThe appearance of the mold is also very important. Nitriding can enhance the surface hardness of the steel and effectively extend the life of the mold; electroplating can usefully modify the mold steel. For some plastic parts that require high brightness and corrosion resistance, electroplating can be used to enhance and improve the function of the steel.
