As a high value-added and technology-intensive product, the level of its technology has become one of the important signs of a country’s manufacturing level.

  Selection of plastic cap mould materials When selecting mold materials, it is necessary to comprehensively consider the use conditions and processing technology of the mold. Generally, such materials for hot molds are often selected from materials such as 5CrMnMO and 5CrNiMO.

  However, due to the low alloy content of the material, when the size of the workpiece plastic cap mold is 300 iTIrn, its hardenability is poor, and the heart will not be hardenable, so this type of material is generally suitable for small-size molds. If the plastic cap mold size is larger, and the shape is more complex generally use 5Cr2NiMoVs and 3Cr2MoVNi and other materials.
