Cold heading reshapes metal using high-pressure dies without cutting away material, resulting in an uninterrupted internal grain flow that increases shear and tensile strength by 15-25%. It also generates virtually zero scrap metal and achieves production speeds up to 300 pieces per minute, significantly reducing unit costs compared to slower CNC turning operations.

For mission-critical assemblies, we issue complete PPAP Level 3 packages including Process FMEA, Control Plans, Material Mill Certifications, 100% Dimensional Inspection Reports, Salt Spray Corrosion Test Reports (ASTM B117), and full substance compliance declarations (RoHS, REACH, IMDS, and Proposition 65).

We tailor anti-vibration performance through mechanical SEMS combinations (captive conical, external tooth, or split washers), pre-applied chemical microencapsulated adhesives (3M, Loctite), or resilient 360-degree nylon patches. For environmental protection, we produce specialized fasteners with integrated elastomeric O-rings engineered into under-head retaining grooves.

Upon receiving 2D/3D design files (STEP, DWG, PDF), our engineering review completes within 24 hours. Dedicated prototype tooling is typically prepared within 7 to 10 working days, followed by sample batch submission for mechanical and dimensional sign-off prior to volume rollout.
