Cemented carbide Lower molded sub-positioning block

Tungsten steel lower mold insert is a key component in mold manufacturing. Combined with its material characteristics and application scenarios, the following is a detailed analysis: **1. Basic concept** - **Tungsten steel (cemented carbide)**: It is made of sintered metal powders such as tungsten (W), cobalt (Co), with high hardness (HRA 85-93), strong wear resistance, but high brittleness, and is suitable for high stress and high wear environments. - **Lower mold**: The part of the mold fixed below the press is completed in combination with the upper mold for punching, forming and other processes. - **Inlet (insert/insert)**: Replaceable parts for embedded mold seats for easy repair and reduce costs. **2. Core features** - **High wear resistance**: Extend mold life, especially suitable for large-scale production. - **High rigidity**: Strong resistance to deformation and ensure molding accuracy. - **High temperature resistance**: Suitable for high-speed stamping or high-temperatur…
