High Speed Flat Die Thread Rolling Machine for Bolt Screw Fastener Production
Flat die thread rolling machine is the core cold forming equipment for external thread making in fastener factories. It works with two flat rolling dies to squeeze the blank and form threads by plastic deformation, instead of cutting off metal material. This keeps the metal fiber continuous, greatly improving thread tensile strength and fatigue resistance.
This machine is widely used for standard bolts, machine screws, self-tapping screws, studs and anchor bolts. It can process metric, inch and special thread profiles. Equipped with automatic feeding mechanism, centralized lubrication system and safety protection device, it supports long-time continuous mass production.
Our thread rolling machine features rigid cast iron frame, stable transmission and low failure rate. The rolling speed can reach 80–320 pcs per minute according to different workpiece sizes. It can be connected after cold heading machine, forming a complete automatic fastener production line.
We support customized die holder, feeding track and control system for different product ranges. Our engineers have rich experience in fastener plant layout. If you need reliable thread rolling equipment for your fastener workshop, send your workpiece size and capacity requirement for quotation.
