Difference between powder metallurgy process and casting process

Difference between powder metallurgy process and casting process

What is the difference between powder metallurgy process and casting process? It is a new knowledge brought to you today. Powder metallurgy process and casting process are two completely different processes. Now let's look at the difference between them.

1. Material difference: the casting material is usually aluminum and zinc, and the powder metallurgy material is usually stainless steel

2. Size difference: casting parts can have a large size range, and powder metallurgy parts will be much smaller

3. Difference in precision: sintering after powder metallurgy injection molding, large size deformation

4. Different surface treatment: different requirements for surface treatment of casting and powder metallurgy

5. Different molding methods: powder metallurgy is formed by fusing low melting point materials between solid particles with adhesive. Only part of the materials melt, and the final product composition remains unchanged, but the powder is consolidated together; Casting is to use the phase transformation of materials from liquid to solid to form, the metal completely melts, and the structure of the final product changes.

To sum up, the difference between powder metallurgy process and casting process has been told to you. If you need to know about powder metallurgy, you can come to Zhongwei Precision Consulting to find out. We have professional staff to answer for you.
