Welcome to visit our company! Nuts 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.
