High-Efficiency Production of Copper Turned Components

C36000 Brass Bars + Modified Automatic Lathes + ISO9001 Certified

We specialize in the mass production of hex copper nuts and precision plated copper turned parts, using high-quality C36000 free-cutting brass bars combined with professionally modified automatic lathes.

Our upgraded machines deliver 25%–35% higher efficiency, helping customers reduce costs while maintaining stable precision and consistent quality.

Why Choose Us

1. Premium Material – C36000 Brass

We offer a wide range of raw material forms:

• Hex bars

• Square bars

• Round bars

• Straight knurled bars

• Diamond knurled bars

• Custom-shaped profiles

We also provide lead-free copper turned parts and hex nuts that comply with EU standards, with RoHS reports available.

C36000 brass (per ASTM standards) offers:

• Excellent machinability

• Smooth surface finish

• Ideal performance for high-speed machining

2. Modified Automatic Lathes – High Efficiency & Stability

By upgrading traditional lathes with automation, we achieve:

• Multi-station continuous machining

• Higher output per unit time

• Improved dimensional consistency

Compared to standard CNC machines, our modified lathes are especially efficient for high-volume production of hex copper nuts.

3. 100% Thread Inspection

All threads are inspected using Go/No-Go gauges, ensuring full compliance with international standards and guaranteeing thread accuracy for every batch.

4. ISO9001 Certified Quality System

Our factory is certified under ISO9001, with full-process quality control:

• Raw material inspection

• In-process monitoring

• Final inspection before shipment

All production is standardized, traceable, and delivery is reliable.
