Harbin Rainbow Technology Co.,Ltd is one of the biggest fastener equipment dealer and manufacturer in China.
We have more than 30 years experiences in supplying all kinds of fastener equipment, such as Bolt Maker, Nut Maker, Cold Heading Machine, Thread Rolling Machine, Wire Drawing Machine, Heat Treatment Furnace and Zinc Plating line, etc. to customers all over the world.

Our mesh belt heat treatment furnace is a continuous automatic production equipment specially developed for fastener hardware industry, widely applied for quenching, tempering, carburizing and carbonitriding of carbon steel, alloy steel fasteners including grade 8.8, 10.9, 12.9 high-strength bolts, nuts, studs and rivets.

Adopting thick reinforced furnace shell and multi-layer ultra-low heat loss refractory insulation structure, the equipment greatly reduces power consumption and long-term operation cost. Equipped with independent multi-zone PID temperature control system, it realizes ultra-uniform heating to ensure consistent hardness, toughness and mechanical performance of every batch fasteners, effectively avoiding defective products caused by temperature deviation.

The 310S high temperature resistant stainless steel mesh belt carries workpieces stably, matched with vector frequency conversion transmission to adjust feeding speed flexibly for different process requirements. We configure complete protective atmosphere system to keep fastener surface bright without oxidation and decarburization, eliminating post-processing polishing cost.

Whole set can be customized as single quenching furnace, single tempering furnace, or integrated quenching-tempering linkage production line according to your factory output and workshop layout. We provide one-stop service including scheme design, production, installation debugging, worker operation training and global after-sales engineer support. The machine runs stably for 24-hour mass production, which is the standard heat treatment equipment for medium and large fastener manufacturing factories worldwide.

Our automatic nut tapping machine is specialized equipment for internal thread tapping of all kinds of nuts, widely matched with cold heading machines in fastener production lines.

Main Product Advantages

1. High tapping precision, stable thread tolerance, low defective rate
2. Full-automatic feeding & tapping, greatly cut manual operation cost
3. Easy mold switching to produce different size nuts flexibly
4. Compact body structure, low failure rate and long service life

This tapping equipment is an essential matching machine for standard parts factories and hardware fastener manufacturers.

Our 3 Die 6 Blow cold heading machine is multi-station automatic cold forging equipment designed for mass production of screws, bolts and rivets. Adopting integrated die set and stable mechanical structure, it completes cutting, pre-forming and heading in one single procedure.

Features:

• High finished product precision, low material waste
• Stable running, long service life of moulds
• Suitable for various fastener raw materials
• Widely used in hardware & fastener manufacturing factory
