This industrial fastener hardening and quenching furnace is purpose-built for the heat treatment of standard and custom fasteners — including bolts, screws, nuts, and rivets. Its continuous feed design enables uninterrupted high-volume production, delivering significant gains in throughput and reduced labor costs for fastener manufacturing operations.

It features a multi-zone heating architecture paired with high-precision PID temperature control, delivering exceptional temperature uniformity across the entire work chamber. This ensures consistent hardness, tensile strength, and mechanical properties across every batch of fasteners. The furnace lining is constructed from premium refractory fiber insulation, minimizing heat loss and cutting energy consumption by over 20% relative to conventional quenching furnaces.

The system supports both water-quench and oil-quench configurations to accommodate process requirements for carbon steel, alloy steel, and stainless steel fasteners. A fully integrated PLC control system with touchscreen HMI provides real-time temperature monitoring, fault diagnostics, and production data logging. Easy to operate and maintain, this furnace delivers a stable, reliable, and cost-effective heat treatment solution for fastener production

Our automatic high speed nail making machine is professional equipment for manufacturing all kinds of steel wire nails. It integrates wire straightening, feeding, cutting, head punching and nail discharging into one fully automatic continuous process. Compared with traditional processing, it features higher production efficiency, lower material waste and more stable nail quality. It is ideal for hardware factories, building material manufacturers and nail production plants.

Our automatic cold heading machine adopts one-die two-blow cold forming technology to produce various screw and bolt heads through cold extrusion of metal wire. It integrates automatic wire feeding, cutting, heading and discharging to realize fully continuous mass production. Compared with traditional machining, the cold heading process generates no material waste, delivers higher production efficiency, and produces formed heads with better mechanical strength. It is ideal equipment for fastener manufacturing plants, hardware factories and automotive fastener suppliers.
