Service
ATA Stainless steel Spinning Service
Stainless steel Spinning is a precision metal forming process that uses a spinning machine to rotate stainless steel blanks while applying pressure with a roller, forming them into hollow, rotational symmetric shapes (such as cylinders, cones and hemispheres) without damaging the material’s inherent properties.
The process is completed by adjusting the rotational speed, roller pressure and feeding speed according to the material type, thickness and forming requirements, and conducting single or multi-pass spinning operations to ensure consistent forming quality.
ATA provides one-stop Stainless steel Spinning services, covering blank selection, process design, precision spinning, post-processing and quality inspection, to meet the customized rotational forming needs of different industries and customers.
