Car Door Lock & Hinge Stamping Components

High-Strength Steel (HSS / AHSS): Engineered for hinge arms and load-bearing reinforcement plates that demand high impact resistance and weight optimization.
Carbon Steel (Cold-Rolled / Hot-Rolled): A cost-effective solution for structural mounting brackets and internal door hardware requiring high rigidity.
Stainless Steel: Selected for latch mechanisms and exposed components requiring superior corrosion resistance in severe environments. 

Engineering & DFM Review: Collaborative analysis of 2D/3D CAD files (STEP, IGES, DWG) to optimize manufacturability, material utilization, and tolerances.
Custom Tooling Development: In-house progressive and multi-stage stamping dies built for high tool life and repeatable high-speed forming.
Prototype & Sample Validation: Early-stage sample validation to verify door fitment, mechanical strength, and assembly alignment before mass tooling commitment.
Controlled Mass Production: Progressive stamping under real-time process monitoring to guarantee lot-to-lot consistency.
Secondary Operations & Assembly: Deburring, automated robotic welding, surface finishing, and hardware insertion (riveting/clinching). 

Inspection Hardware: Coordinate Measuring Machines (CMM), Optical Projectors, Salt Spray Testing Cabinets (corrosion resistance), and Tensile/Hardness Testers.
Process Assurance: First Article Inspection (FAI), in-line Statistical Process Control (SPC), and 100% critical feature verification.
Traceability: Full material mill certification and batch tracking for total supply chain transparency.
