Cold heading machines

Cold forming machines shape metal at room temperature through high-pressure plastic deformation, preserving grain flow and enhancing mechanical properties. This chipless process reduces material waste and eliminates scale—critical for high-strength fasteners. Modern units like YUHAI TBF, TFD, TFW, TNF, and PROLU Z-G feature multi-station dies and automatic wire feeding, enabling up to 5 operations in one stroke: cutoff, head forming, shaping, sizing, and flash trimming.

These machines are essential in automotive, construction, energy, and appliance manufacturing, where consistency and throughput are paramount. Double- and triple-blow models (e.g., TFD6-150, YH10-3S) handle complex geometries—such as multi-step bolts, flanged nuts, and bearing balls—with precision and repeatability.

KNAVI GROUP supplies cold forming equipment directly from top Chinese manufacturers. All machines include full English documentation, pre-commissioning checks, and up to 2 years of warranty. Tooling for DIN, ISO, or custom fastener designs is available upon request.

Direct factory supply ensures fast delivery worldwide. Operator training and on-site commissioning are included.
