Cold Rollforming Technology

Post Punching Mould

XHH LGS Machine all with post punching and post cutting, which make more high precision performance on position & dimension

Seamless end cut connection

Seamless end-cut connection is a patent design of XHH LGS FORMER. The two ends of the vertical frame can seamlessly connect to the web of the bottom and top horizontal frames. So the weight of the house can be directly loaded and passed by the vertical frame, which makes the house safer.

Continuous web notch punching without extruding material

The strength of raw material will be greatly reduced when continuous web & lip notches are made, thus material in the pre-punching machine may be easily extruded and then cause machine jam during roll forming process. XHH LGS Machine with post punching system, which we can do more continuous web notch even in 0.55mm thin thickness without extruding material.

Lower material wasting

Short distance between punching & cutting die able to limit the start-up material waste length at 0.02m, and end material waste length within 1 meter.

Save Cost

XHH Machine steel strip width is: 170-174mm width, 10mm less than the most other machines in the market. For a 200sm house, the total frame is around 7000m，can save 439.6-659.4kg material

The length of each start-up waste of the XHH post-punching & cutting machine is about 1M; most machines on the market are pre-punching & post-cutting (other supplier), their waste material is about 8m on each start-up
