1) Cutting:
The end of the reinforcement bars is sawn square.
2) Cold Forging:
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.
3) Threading:
An ISO standard metric thread is then cut

Reinforcement by Coupler's System,
Steel bar Thread Cutting Machine
Steel bar Thread Cutting Machine
This machine is used to cut the thread for rebar end after cold forging.
Upset parallel threaded couplers are suited to projects which require high volumes of couplers. They produce a full strength joint in the rebar connection. The ends of the bars to be joined are cut square and enlarged by cold forging to increase their core diameter and so ensure that the joint is stronger than the bar. The couplers are usually supplied attached to the reinforcing bar.
