1. High Strength Alloy Cast Iron Body

The whole frame adopts alloy cast iron with outstanding tensile strength, passed official national inspection. It features excellent shock absorption capacity, stable operation during high-speed stamping and feeding, low vibration to keep long-term machining precision.

2. Integrated One-Piece Main Slide Block

Extended integral casting slide block processed by imported five-axis machining center, one-step forming processing ensures long-term stable precision and wear resistance for continuous mass production.

3. Patented Modular Clamp Transfer System

Our self-developed patented modular clamping unit realizes high-speed and high-precision workpiece transfer. Easy operation and maintenance, greatly shorten the debugging learning time for new operators. This multi-station transfer design supports manufacturing various fastener products, including inner hex screws, outer hex bolts and other custom special-shaped small connectors within the processing range.

4. Precision Dual Wire Feeding Assembly

Double feeding structure with adjustable air pressure and high-precision transmission gears. The stroke of each station can be adjusted independently, realizing stable blank conveying, ejection and trimming functions.

5. Cam Driven Front & Rear Ejection Device

Built-in cam module controls front and rear ejection length, eject finished workpieces smoothly without deformation.

Full Servo Intelligent Control System

This high-speed precision multi-station cold heading machine is equipped with servo driving motor and PLC intelligent operation detection system (operating voltage above 280V):

• Built-in voltage protection module to stabilize factory power grid, reduce power consumption by more than 30%
• Fast forward and backward inching response, molds can complete displacement adjustment within seconds
• Consistent torque output at low and high speed, linear control improves machining accuracy
• Stepless speed regulation to match different production requirements of various fastener styles

Complete production workflow for standard and special fasteners: Pickling & Phosphating Coil → Cold Heading Machine → Tooth Rolling Machine → Semi-Finished Fastener → Mesh Belt Heat Treatment Furnace → Rolling Galvanizing Equipment → Finished Fastener Products.
