High Precision Automobile Casting Components Surface Roughness Ra 3.2 ~ Ra 6.3

We can customize various car casting products for customers. The process of the car gradually cast the melting metal into the mold and solidified, thereby generating the required shape. Due to its strength, durability and complex geometric shapes, casting components are widely used in the automotive industry.
