Service
ATA Stainless steel Deep drawing Service
Stainless steel Deep drawing is a precision metal forming process that uses a punch and die to draw stainless steel sheets into hollow cylindrical, rectangular or irregular shapes without damaging the material’s inherent mechanical properties.
The process is completed by designing customized dies, adjusting drawing pressure, speed and lubrication parameters, and conducting multi-pass drawing operations to ensure smooth forming and consistent quality.
ATA provides one-stop Stainless steel Deep drawing services, covering die design, material selection, precision drawing, post-processing and quality inspection, to meet the customized hollow forming needs of different industries and customers.

Stainless steel Deep drawing Quality Control
ATA adheres to the whole-process quality management concept in the Stainless steel Deep drawing process, from the incoming inspection of stainless steel materials to the final inspection of finished products, strictly implementing international industry standards to ensure that each batch of products meets customer design requirements; we use professional testing equipment and scientific testing methods to conduct comprehensive inspections on the deep drawing quality, and the specific testing methods are as follows:
- Wall thickness uniformity test: Use a thickness gauge to detect the wall thickness of different parts of the deep-drawn product, ensuring that the thickness difference is within the allowable range and avoiding uneven stress distribution.
- Dimensional accuracy test: Use a coordinate measuring instrument to detect the key dimensions of the product, ensuring that it is completely consistent with the design drawings and meeting the assembly requirements with other components.
- Stainless steel Deep drawing surface inspection: Check the surface of the product for scratches, wrinkles and cracks, and ensure that the surface finish meets the brushed stainless steel finish or customized standards.
- Structural strength test: For key deep-drawn components, conduct pressure and impact tests to verify that the structural strength after drawing meets the service life and safety requirements of the product.
