Product Details

Welcome to visit our company! Bolts making machine.

The composition of the production line is cold heading machine head forming machine( edge-trimming machine) and thread rolling machine. Our company is professional to manufacture cold heading machine head forming machine( edge-trimming machine) and thread rolling machine. The technology of our machine is mature. The stability of our machine is good and the quality of our products is high. The type of our machine is complete. Our machine can product bolt nut rivet pin and so on.

Our machine can manufacture all kinds of heads products and the diameter of bars is 4-30mm.

Advantage

High automation	2 machines are operated by 1 person only.
High utilization	The entire brass rod(Φ15- Φ30) can be put into the machine.
High productivity	The production rate is 30-100 pcs/min.(depend on the product's size). It is 5 times higher than the normal machines.
High passing rate	>98%(the traditional one has 90% only)
Safety	High safety performance, no work injuries.
Low production cost	(1)Gas and electric motor are used as fire heating. (2)Medium frequency furnace(60-100) and electric motor are used as intermediate frequency heating. (3)30% of the electric power can be saved.
Customization	Customization is available.
Trimming	Products are without trimming (no unwanted material on the product).

Application Field

For the production parts: copper core, flare nut, valves, plumbing fittings, brass nuts, screw nuts, valve element, connector, single connector, internal thread and so on.

The picture of the product line
1.The production line ( the cold heading machine is 2 station): cold heading machine + head forming machine(edge-trimming machine)+thread rolling machine.

Feeding → preliminary forming → head forming → the last forming → feeding → rolling thread

→

2.The production line(The cold heading machine is Multi-station cold heading machine) : cold heading machine + thread rolling machine

Feeding →forming(semifinished product) →feeding (thread rolling machine)→rolling thread →finished product.
