Cold Forging Upsetting Machine 

Rebar Threading Machine

Cutting:

1) The end of the reinforcement bars is sawn square.

Cold Forging:

2) With the help of patented cold forging, the sawn end of the reinforcing bar is then enlarged. With this the core diameter of the bar is increased to pre determined diameter.

Threading:

3) An ISO standard metric thread is then cut.
