EF Hardware Factory

EF INTERNATIONAL CO. LTD  has a state-of-the-art stamping workshop dedicated to producing lever arch mechanisms and ring binder mechanisms. Our facility uses high-precision stamping machines to cut and shape metal sheets efficiently, ensuring consistent dimensions, smooth edges, and high-quality parts ready for assembly.

Advanced Stamping Equipment

• High-precision stamping machines: produce uniform and accurate metal parts

• Material options:  steel for durability

• Production capacity: thousands of stamped pieces per day

• Quality control: each piece inspected for size, edges, and surface defects

This automated stamping process reduces human error, improves efficiency, and lays the foundation for durable lever arch and ring binder mechanisms.

Integration with Assembly Workshop

• After stamping, parts are transferred to electroplating ,then assembly lines

• Supports OEM & ODM orders, including custom sizes, thickness, and packaging

• Fully aligned with our automated assembly workshop to guarantee stable quality

1. 23+ years of experience in metal stamping and mechanism production

2. Modern workshop with automated lines and strict quality inspections

3. High efficiency and cost-effective production

4. Exported to over 30 countries, trusted by global stationery brands
