• Excellent weldability compared to conventional martensitic grades

• Aerospace, oil/gas, and high-stress component applications

Our precision casting process utilizes advanced lost wax technology to produce high-quality stainless steel components with exceptional dimensional accuracy and surface finish.

Process Overview:

1. Pattern Creation: Wax patterns are formed and assembled into clusters

2. Shell Building: Multiple refractory coatings are applied to create ceramic molds

3. Wax Removal: Molten wax is eliminated from the hardened shell

4. High-Temperature Casting: Molds are fired and filled with molten stainless steel

Material Advantages:

• Superior corrosion resistance

• Excellent mechanical properties

• Wide material selection (carbon steel, alloy steel, stainless steel)

• Ideal for applications requiring both strength and durability

Our Quality Process:

• Computerized pouring simulation

• Precision mold development

• Strict raw material inspection

• Automated shell preparation

• Controlled heat treatment

• Comprehensive final inspection

As an experienced investment casting manufacturer, we ensure:
✔ Consistent quality control at every stage
✔ Reliable production timelines

Cast Stainless Steel Mold Development

Our stainless steel foundry technical department develops the mold, and the quality department uses the three coordinates to carry out the dimensional inspection.

Stainless Steel Foundry Wax Pattern

Our workshop uses automatic waxing machines to set the waxing pressure, holding time, etc., and to

produce high quality was patterns.

Stainless Steel Foundry Shell Preparation

Our workshop has 6 automatic production lines, able to produce 2600 sets of shells every day. We

use a hygrothermograph, aerometer, and PH to monitor humidity, temperature, and concentration

of liquor aluminum chloride.

Casting Stainless Steel Metal Pouring

8 sets of 600KG furnaces are in production, and 4 sets of 500KG spare furnaces are ready when

capacity increases.The operators conduct rigorous tests to fulfill material requirements.

Cast Stainless Steel Clean And Heat Treat

Our workshop is fully equipped with 12 heat treatment furnaces, 6 quenching furnaces, 4 central

shot blasting machine and 16 large shot blasting machines.
