Here are three advantages of pipe casting aluminum castings. The pipes are made of stainless steel, which has good corrosion resistance and allows for complex shapes. By casting while maintaining high adhesion between aluminum castings and SUS pipes, the cooling effect is enhanced. We also have manufacturing examples where cooling pipes are cast across the entire surface of 2000mm wide aluminum castings. Please feel free to consult us when needed. 【Three Advantages】 ■ Complex shapes are possible ■ Improved cooling efficiency ■ Pipes made of stainless steel have good corrosion resistance *For more details, please refer to the PDF document or feel free to contact us.
