  • The difference between powder metallurgy and casting
  • Editor：Hangzhou Hongcheng Pml Precision Mechanism LtdDate：2017-10-13 13:22 Click：
Nowadays, all kinds of products we use in our life are made by molding technology. We know that there are two kinds of molding technology. They are powder metallurgy and casting. They are all forming technology of a kind of material. There are similarities but also differences. What is the difference between powder metallurgy and casting? < /div>
Now, we use a variety of shapes in the life of the. Hat is the difference between the powder metallurgy with the cast?
1. The difference between materials: casting materials are usually aluminum and zinc, and powder metallurgy materials are usually stainless steel;
1, the difference between the material: casting materials are usually aluminum and and,
2, size difference: casting parts can have a large size range and powder metallurgy will be much smaller;
src=2, the difference between size: casting parts can have a large size size,
3. Accuracy: sintered after powder metallurgy and large deformation,
3, precision: powder metallurgy after injection molding, sintering, size deformation is very large;
4. Different surface treatments: Casting and powder metallurgy surface treatment will also have different requirements;
The 4 is surface treatment is different: the surface treatment of casting and powder and
5, molding different: powder metallurgy is the use of solid particles between the low melting point material and adhesive fusion to form, only part of the material melting, the final product composition is not changed, only the powder consolidation together; casting is the use of material from liquid to solid phase transformation, metal completely melt, the final product of the organization The structure changes.
5, forming different: powder metallurgy is the use of solid particles between the. To the solid phase was formed, the metal melt completely, the, melt,
The above is the difference between powder metallurgy and casting, which is introduced here, whether it is powder metallurgy or casting, each has its own uses and values. But the appearance quality of powder metallurgy surface is better than that of casting. Stainless steel powder is often used for small products or inaccurate large products.
The above is about the difference between powder metallurgy and casting. Small pieces or bulky products.
