High-Performance Automatic Open Die Cold Header for Complex Fasteners
Whether you are manufacturing ultra-long bolts or complex components, our Automatic open die cold header solutions provide the precision and power needed for modern fastener production. Integrating advanced High-speed Fastener die clamping machine technology, our equipment is engineered to handle the most demanding geometries with ease. From standard long-stroke bolts to tailor-made open die cold forming machine configurations, we bridge the gap between China’s manufacturing efficiency and Taiwan’s precision engineering.
What is an Open Die Cold Heading Machine?
An open die cold heading machine is a specialized piece of equipment used in the fastener industry to shape metal wire at room temperature. Unlike standard closed-die headers, this machine features a fastener opening and closing die mechanism. This allows the dies to open after the heading stroke, enabling the production of parts with multiple shoulders, extremely long shanks, or large diameter heads that would otherwise be trapped in a conventional solid die.
By utilizing a customized fastener mold clamping machine system, the wire is securely gripped during the forging process. This ensures that even for double-headed parts or asymmetrical shapes, the metal flows precisely into the die cavities. Our custom open die cold heading machine models are essential for manufacturers in the automotive and aerospace sectors who require high-strength, near-net-shape components without the material waste of machining.
Versatile Applications for Multi-Shoulder and Special Shape Parts
The primary advantage of a tailor-made open die cold forming machine is its versatility. Our equipment is specifically designed to produce:
- Multi-shoulder bolts and tiered shafts.
- Double-head fasteners used in heavy construction.
- Extra-long solid parts with shank diameters ranging from Φ1.5mm to Φ20mm.
Equipped with stepless variable speed controls and optional load monitors, our automatic open die cold header ensures consistent quality at high speeds. For environments requiring noise reduction, integrated sound enclosures are available, making our machines the ideal choice for modern, high-efficiency factories.
