Mass Precision Hardware Manufacturing
CHX Metal (Shenzhen Changhexin Precision Hardware) operates 220+ CNC machines - including imported 5-axis machining centers and mill-turn complexes - for mass production of precision hardware in aluminum, stainless steel, copper and steel. Accuracy to ±0.005mm, ISO 9001:2015 certified, serving EV, 3C electronics, robotics and medical customers from prototype to million-piece volumes.
Mass Production Scale
Monthly output exceeds one million pieces across mixed-material programs. Dedicated production cells are assigned to long-running part numbers, with standardized fixturing and tooling strategies frozen after first article approval. Capacity planning is reviewed monthly so seasonal peaks in consumer electronics and EV programs do not break delivery schedules.
Consistency Controls
Batch consistency rests on three controls: equipment stability from imported 5-axis and mill-turn machines, frozen process documentation (fixturing, tool paths, cutting parameters), and closed-loop inspection where a coordinate measuring machine (CMM) verify full dimensions on first article, batch start, and final release. CpK is tracked on critical features for volume programs, and SPC data is shared with customers on request.
Materials & Tolerances
Aluminum 6061/7075, stainless 304/316, copper and brass, carbon and alloy steels, plus engineering plastics. Typical accuracy ±0.005mm with CpK-monitored critical dimensions. Material certificates (EN 10204 3.1) ship with every lot.
Industries Served
- New energy vehicles: battery brackets, busbar mounts, cooling components
- 3C electronics: housings, structural frames, heat sinks
- Robotics: RV reducer parts, joint housings, end effectors
- Medical: instrument handles, diagnostic device parts
Quality System
ISO 9001:2015 certified with full material traceability. First article inspection is mandatory on every new part number, and FAIR/PPAP documentation is available for automotive programs. Inspection reports accompany every shipment.
Lead Time & Logistics
Prototypes in 3-7 days, mass production 7-15 days, surface treatment adds 5-10 days. Quotations with DFM feedback within 24 hours. Export packing with anti-scratch and corrosion protection, worldwide express and freight shipping from Shenzhen.
