Welcome to Qiujing Group.

Centrifugal casting

Utilizing controlled mold filling under gravity ensures stable metal flow and good dimensional accuracy. This process produces castings with smooth surfaces, clear contours, and a sound internal structure, effectively reducing machining allowances. It is an ideal choice for engine components, structural parts, and a wide range of industrial castings.
