Press forming is a very important step in the cemented carbide manufacturing process and has a direct impact on the manufacturing of cemented carbide. The following are the effects of press forming on carbide manufacturing:
- Shape and size: The main purpose of press molding is to press raw powder into a dense body with specific shape and size. The compression molding process needs to be carried out under high temperature and high pressure conditions, which can make the raw material powders more tightly bonded to achieve the required shape and size.
- Density and strength: During the compression molding process, the density and strength of the raw material powder are important factors that affect the performance of the final product. Products with higher density and greater strength have better properties such as hardness and wear resistance.
- Pressure: During the press molding process, the size of the press pressure is also an important factor affecting product performance. Appropriate pressing pressure can ensure the density and strength of the product, while excessive pressing pressure can cause product deformation or cracking.
- Sintering quality: The pressed cemented carbide needs to be sintering to further promote the bonding and densification between powders. Factors such as temperature, time and atmosphere during the sintering process also have an important impact on the performance and quality of the final product.
In short, press forming is one of the key links in the cemented carbide manufacturing process. It has an important impact on the manufacturing of cemented carbide and is one of the important steps to ensure the quality of the final product.
