The cold pressing machine can process rebar diameter from 16mm to 40mm and the coupler can link the rebar from 16mm to 40mm. Principle:

Using the cold pressing machine to press connection point to link the two rebar.

The cold pressing machine including two set of machines:
1) YJ650: Process rebar whose diameter is from 16mm to 32mm.
2) YJ800: Process rebar whose diameter is from 36mm to 40mm.

Features:
1) Because of the good resistence of the joint, it is widely used in bridge constructions.
2) No flammable gases, not affected by rainy or cold weather, easy to operate.
3) Saves 80% connector steel consumption.
4) The system most used when one end of rebar has been fixed and couldn't be revolved.
