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). |
