Precision injection mold refers to the high-precision molds used in the plastic injection molding process, which are capable of molding complex, high-precision plastic products. This kind of mold consists of static mold and moving mold, the static mold includes gate sleeve, backing plate, template and so on, while the moving mold has moving template, moving mold backing plate, mold release mechanism and so on. The use of sprue sets facilitates the installation of molds and the replacement of sprues.
The design of precision injection mold needs to consider many factors, such as injection cost, parting surface location, nozzle method, ejector method, cooling or heating method, mold life, processing difficulty and so on. Poor design is prone to defects and should be designed for overflow and venting.
In the choice of injection mold steel, you need to consider the size of the mold, complexity, production requirements and economy and other factors. Commonly used injection mold steel are P20, 718, NAK80, S136 and H13, etc. Different steel has different characteristics and scope of application, such as P20 low hardness, low price; 718 high hardness, corrosion resistance; NAK80 high hardness, wear-resistant; S136 high hardness, wear-resistant; H13 good heat resistance.
The manufacture of precision injection molds requires the use of high-precision processing equipment and technology, such as CNC machine tools, EDM, wire cutting and so on. At the same time, nowadays the molds basically have to be heat-treated to improve the service life of the molds.
The use of precision injection molds requires attention to maintenance and care to ensure their accuracy and service life. Manufacturers need to consider how to use low cost to create high efficiency, and at the same time need to pay attention to the quality and stability of the molds to improve the competitiveness of their products.
Generally speaking, the design and manufacture of precision injection molds require the use of high-precision processing equipment and technology, such as CNC machine tools, EDM, wire cutting, etc., to ensure the accuracy and quality of the molds. At the same time, in order to improve the service life of the molds, the molds nowadays basically need to be heat-treated.
When using precision injection molds, attention needs to be paid to the maintenance and care of the molds to ensure their precision and service life. Manufacturers need to consider how to use low cost to create high efficiency, and at the same time need to pay attention to the quality and stability of the molds to improve the competitiveness of their products.
The use of precision injection molds requires attention to maintenance and care to ensure their accuracy and service life. Manufacturers need to consider how to take advantage of low cost to create high efficiency, and at the same time need to pay attention to the quality and stability of the mold, in order to improve the competitiveness of the product. Mold manufacturers need to start thinking about mold life and maintenance in the early stages of product development to avoid unnecessary cost increases and production time delays later.
