Service
ATA Stainless steel Piercing Service
Stainless steel Piercing is a precision metal forming process that uses a punch and die to punch precise holes, slots or notches in stainless steel materials, without damaging the material’s inherent mechanical properties or surface finish.
The process is completed by designing customized piercing dies, adjusting punch pressure and speed, and conducting continuous piercing operations to ensure batch consistency and hole precision.
ATA provides one-stop Stainless steel Piercing services, covering die design, material selection, precision piercing, post-processing and quality inspection, to meet the customized hole-forming needs of different industries and customers.

Stainless steel Piercing Quality Control
ATA adheres to the whole-process quality management concept in the Stainless steel Piercing 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 piercing quality, and the specific testing methods are as follows:
- Hole diameter test: Use a precision caliper and gauge to detect the diameter of the pierced holes, ensuring that it is completely consistent with the design drawings and meeting the assembly requirements.
- Position accuracy test: Use a coordinate measuring instrument to detect the position of the holes, ensuring that the position error is within the allowable range and avoiding deviation affecting assembly.
- Stainless steel Piercing surface inspection: Check the hole edge and material surface for burrs, scratches and cracks, and ensure that the surface finish meets the brushed stainless steel finish or customized standards.
- Batch consistency test: Sample inspect products in each batch to ensure that the hole diameter, position and edge quality of all products are consistent, avoiding batch defects.
