Our Casting Capabilities
Casting Manufacturer: Pressure Testing and Non-Destructive Testing
We ensure that our castings undergo pressure testing. We also perform non-destructive testing (NDT) to verify the integrity of the products. We guarantee that all products we manufacture are leak-free. Additionally, our silica sol casting process ensures excellent surface finish and dimensional accuracy. This allows us to meet the drawing requirements through casting alone, eliminating the need for additional machining. This provides our customers with unparalleled surface treatment and ensures top-notch quality.
