The working part of the injection mold is the mixing of raw materials.In China，many companies cannot buy real products.Improper material selection，poor material performance，and no wear resistance; the material of the injection mold is the life of the mold，and the quality of the mold is reduced due to problems with the mold material.Second，The heat treatment of the mold is also an important part of the quality of the mold.Because the mold material is unqualified or the heat treatment fails，the quality of the mold is also the main factor.Again，the mold steel is not refined，there are a large number of melting defects，the punch and concave mold，the forging process is not perfect，There is a hidden danger of heat treatment.
The forming process is not perfect，mainly manifested in the poor internal quality of the punch and die forgings，there are problems with the heat treatment process and process，the quenching of the punch die，the soft spots and the hardness are uneven.Sometimes cracks，even cracks，grinding and polishing are not In place，the surface roughness value is too large.The market requires finer external molds and beautiful design.It is the work that needs to be done in the design process.Finally，on the one hand，the cost of the lower cover plate mold The designed mold production equipment and the working production cost of the mold are the practical significance of the development of the mold industry.Implementing a proactive fiscal policy and a stable monetary policy，vigorously strengthening the growth mode of independent innovation and industrial transformation，and optimizing the industrial structure，the need for high The level of mold machinery and equipment provides a broad development space for the development of the mold industry.
