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…
