Factory introduction


Baoding Jindi Machinery Co., Ltd is a professional manufacturer of steel mechanical splicing & processed products such as rebar coupler, rebar thread rolling machine, rebar cutting machine, rebar bending machine, etc for concrete reinforcement structure. So far, our products have been selling to global market like Vietnam, India, Russia, Ukraine, South Korea, Singapore, Indonesia, Brunei, Thailand, Malaysia, UAE, Saudi Arabia, Iran, Mexico, America, Brazil, Ghana, etc with the certificates of CE, GOST, ISO9001:2008, SGS, JGJ107-2010.


Machine Function 


It is mainly applied to peel rebar rib first, then roll parallel thread on rebar end, after that, two threaded rebar sectors could be connected by coupler. It is a necessary machine for rebar joint.


In addition, it is also applied to roll threads on round steel bar, anchor rod, or other equivalent materials.




Machine Advantages


1. Both right-handed threads & left-handed threads could be processed with one machine head.


2. Simple operation, reducing workers' labor intensity. 


3. Shortening construction period.High processing speed and production efficiency.

 Brife introduction


JBG-40K is designed for processing parallel threads for rebar mechanical connection in construction. It can process HRB335,HRB400, HR500hot rolled ribbed reinforced bar with diameter 14-40mm. It uses larger machine rac which makes machinemore stable. It adopes famous brander reducer, the machine performance is more superior. It also adopes patented design which aliminates the problem that the rebar thread often becomes bigger, and that the stripping head automatically open.


JBG-40KI , as updated type of JBG-40K, is our new product developed in 2013. It adds the screw pitch angle mechanism. It is easier t operate, the thread precision is more highr, the conical degree is more smaller, and the thread surface is more smooth.
