Powder metallurgy: It is the process technology of preparing metal or using metal powder (or a mixture of metal powder and non-metal powder) as raw materials, forming and sintering, manufacturing metal materials, composite materials and various types of products.
advantage:
1. Most refractory metals and their compounds, pseudo-alloys, and porous materials can only be manufactured by powder metallurgy.
2. Save metal and reduce product cost.
3. It will not cause any pollution to the materials, and it is possible to prepare high-purity materials.
4. The powder metallurgy method can ensure the correctness and uniformity of the material composition ratio.
5. Powder metallurgy is suitable for producing products with the same shape and large quantity, which can greatly reduce the production cost.
shortcoming:
1. Consider the size of parts when there is no batch.
2. The cost of mold is relatively higher than that of casting mold.
Production scope:
Powder metallurgy technology can directly produce porous, semi-dense or fully dense materials and products, such as oil-bearing bearings, gears, cams, guide rods, knives, etc.
