Our manufacturing facility is equipped with 50+ production machines spanning the complete fastener manufacturing chain — from multi-station cold headers and precision CNC turning centers to automated optical sorting systems. With ±0.01mm precision, 95% process automation, and 24/7 continuous operation, our equipment fleet delivers consistent quality at production scale.
Core Machinery & Equipment
Our equipment fleet covers every stage of fastener production — from wire rod to finished part
Multi-station Cold Headers
4-station and 5-station cold heading machines producing bolts, screws, and custom fasteners from M2 to M24. Single-pass forming of hex heads, flanged heads, and special profiles with superior material utilization. Capable of 300 pieces/minute at full speed.
CNC Turning Centers
Precision CNC lathes and 3-axis machining centers for complex geometries, custom spacers, turned aluminum components, and small-batch fasteners. Automatic bar feeders enable lights-out continuous operation with ±0.01 mm tolerance and Ra 0.8 surface finish.
Thread Rolling Machines
Flat die and planetary thread rolling machines for work-hardened thread formation. Cold-rolled threads achieve 20–30% higher fatigue strength than cut threads, with superior surface finish and no material waste. M1.6 to M20 range across all standard and fine pitches.
Heat Treatment Furnace
Continuous mesh belt furnace for quenching, tempering, and annealing — all with ±5°C temperature control up to 950°C. Ensures optimal and repeatable mechanical properties across production lots. Carburizing capability available for case-hardened fasteners.
Quality Control & Inspection
Rigorous multi-stage inspection protocol using calibrated gauges, micrometers, thread plug/ring gauges, and profile projectors. AQL sampling per ISO 2859-1 with tightened inspection for critical dimensions. Dimensional reports and certificates provided with every shipment batch.
Surface Treatment Solutions
Comprehensive surface treatment options delivered through a managed network of qualified coating specialists. We source and coordinate the right finish for your requirements — Dacromet, Zn-Ni, zinc electroplate, black oxide, PTFE, TiN, DLC, and passivation — with full quality verification before shipment.

Smart Manufacturing Advantages
Automation, traceability, and intelligent systems that drive quality and efficiency
Automated Production Lines
Integrated automation from raw material to finished product. Cold headers, CNCs, and sorters linked through automated material handling — minimizing human error and ensuring batch-to-batch consistency.
Real-time Quality Monitoring
In-process SPC and vision systems monitor critical dimensions in real time. Deviations trigger immediate alerts — enabling corrective action before a single non-conforming part reaches the next station.
Full Barcode Traceability
Every batch is tagged at raw material receipt and tracked through every production step to final shipment. Heat numbers, machine IDs, operator stamps, and inspection results are linked — providing complete lot-level genealogy.
Global Standard Compliance
Equipment, processes, and documentation comply with ISO 9001:2015 (BV certified), ISO 898-1, ASTM F606, and DIN 267. Test certificates are available in Chinese and English — ready for your import compliance file.
Rapid Tooling Changeover
Quick-change tooling systems and standardized die sets enable fast changeover between product variants. This flexibility supports both high-volume production runs and short-batch custom orders without sacrificing efficiency.
Smart Warehouse Integration
5,000 m² intelligent warehouse with FIFO inventory rotation, automated material handling, and real-time stock visibility. Integrated with production scheduling to ensure raw material availability and finished goods readiness.
