1. Talwan heavy-duty design, whole machine weight more than 20tons, gearbox transmission  (high transmission efficiency and accurate transmission ratio) , machine service life more than twice that of other Indian and Chinese cheap machines.

2. One machine for multi-profiles: any C purlin within web range 40-160mm, saving investment and space .

3. Allows you to offer clients 24-hour customized C purlin service an various gauges of material, this includes different widths and flange height combinations..

4. Servo motorized automatic changeover for different C purlinswithin 1-5 minutes, saving time and improving work efficiency.

5.Eight-cylinder punching system can meet various punching holes requirements of the solar industry.

6. European cast steel forging structure with anti deformation and high load bearing capacity, ensures the machine forming accuracy.

7. Servo Controlled Precision Flying Post Cut Off System (for high working efficiency). 

8. The latest PLC control system is adopted to ommbine two sets of length counting methods ( infrated counting-hole length counting and encoder-counting-wheel length counting) into one PLC control system.The length counting method can be switched to solve the problem of incompatibility due to the special length of individual orders.

9. Equipped with water cooling system to cool the roller and profile, extend the service life of roller and ensure the quality of finished profiles.
