Principle of cold stamping system:

 
Using the machine to press connection point to link the two rebar

The machine including two set of machine:

 1) YJ650: process rebar whose diameter is  from 16mm to 32mm.

 2) YJ800: Process rebar whose diameter is from 36mm to 40mm.

 3) YJ650 machine and Pressure equipment of YJ800 can process diameter 16-40mm.

 Advantages:

 1) Because of the good resistence of the joint,it is widely used in bridge constructions.

 2) not affected by rainy or cold weather,easy to operate.
