About Stainless steel casting
Stainless steel casting, or stainless steel investment casting, is the lost wax investment casting process by pouring melton stainless steel into moulds for solidification, thus to achieve a solid stainless steel component in desired shape.

The features of the Stainless steel casting
The precision casting can be ensure that the product accuracy reach CT4-6 level, and the surface roughness is 0.4~3.2μM, so the precision casting products is processed-free finished products or semi-finished products.
And the casting can make any complex products and difficult products that hard to produce.
The size can be smaller to 1mm,the thicness can be 0.5mm, the holes can be 1.0mm.
Also the casting technology can make big orders or small orders.
Our professional casting process technology makes the products have no internal defects such as pores, slag inclusions, shrinkage porosity, etc., and the organization is uniform and compact.
All products can meet or exceed the national implementation standards, ministerial standards, military standards and special technical conditions. Internal X-ray inspection It can reach the standard of navigation mark I and class I.

Advantage Of The Stainless Steel
In addition to being corrosion and rust resistant, stainless steel is extremely durable. It retains strength at both remarkably high and exceptionally low temperatures, won't buckle under weight, and can endure weather extremes. Lastly, stainless steel is environmentally friendly. It's 100% recyclable, and many stainless steel products contain previously recycled material.
