Stamping Process
We use presses with capacities that handle a wide range of sheet thicknesses, from thin precision parts to heavier structural plates. The stamping process includes blanking, punching, forming, embossing and bending. Our tooling is maintained regularly to ensure consistent output. Dimensional checks are performed with calipers, micrometers and coordinate measuring equipment to verify that every batch matches the technical drawing.
Welding and Assembly
Welding is performed by certified operators who select the appropriate method based on material type and service condition. The assembly stage brings together stamped components, fasteners, weld nuts, inserts and any required hardware. After assembly, each unit is inspected for weld appearance, dimensional correctness, surface finish and overall functionality.
Quality Control
We operate under ISO9001 and ISO16949 management systems, which ensure traceable procedures from material receiving to final packing. Incoming raw materials are verified with mill test reports. In-process inspections cover workpiece dimensions and weld quality. Final inspection includes fit-up, surface condition, and packaging reliability. This multi-level QC approach helps prevent defective products from leaving the factory.
