n the high-volume world of self-drilling screw manufacturing, the efficiency and reliability of the blank production stage are paramount. Our Two-Blow Cold Heading Machine serves as the core of this initial yet critical operation, engineered specifically for the high-speed and consistent output of premium screw blanks. Its two-strike, single-die process is exceptionally adept at rapidly forming the near-net-shape blanks required for self-drillers, achieving production rates that far outpace simpler or less specialized equipment, ensuring a steady and sufficient supply of blanks for subsequent processing lines.
This remarkable efficiency is built upon a foundation of extreme durability. Forming the preliminary and final shapes of a screw blank in two powerful blows places significant stress on the machine's components. Our self drilling screw maker is built to withstand this demand. The widened and thickened crankshaft, manufactured from a special high-wear-resistant alloy, provides the immense strength and toughness needed for continuous, high-impact operation. The integrally formed curve slide plate, devoid of weak insertion pieces, and the shock-absorbing slider base plate work in concert to ensure smooth, high-velocity operation while mitigating the intense forming forces. This robust construction not only enables high speed but also protects the machine's precision over the long term, ensuring that the first blank produced is identical to the one-millionth.
Operational uptime is further maximized through intelligent system design. The rationally laid-out oil circuit ensures that all high-speed moving parts, from the crankshaft to the guides, receive adequate lubrication, reducing friction and heat. The automatic low-oil shutdown function provides a critical safeguard, preventing catastrophic damage and unplanned production halts. Powered by a reliable Taiwanese motor and controlled by a stable Schneider electrical system, the machine offers a dependable power foundation for non-stop blank production. This synergy of speed, durability, and operational intelligence makes our cold header the ideal starting point for a highly efficient and profitable self-drilling screw manufacturing workflow.
