1. Description of upset forging parallel thread system

(1) GD-150 Upset forging machine
Working range: 12mm- 40mm
Motor power: 4.0KW
we use GD-150 to forging the end of rebar.

(2) GZL-45 threading machine
Working range: 12mm- 40mm
Motor power: 3/2.4KW
we use the GZL-45 to threading the end of rebar.
The tensile strength of rebar connector is not less than 627MPA, 
and the tensile strength of super coupler can be reach 800~900MPA

3. Advantages of carbon steel parallel thread mechanical rebar splice coupler

1), Adopts upset forging parallel thread connection technology;
2), Wide working range: Adaptable for 12mm-40mm same diameter, different diameter, bending, new and old, advance covered up rebar of GB 1499, BS 4449, ASTM A615 or ASTM A706 standard.
3), High strength: Stronger than the reinforcement bar and guarantees bar break under tensile stress(tensile strength of connection point =1.1 times of connected bar's specified tensile strength). It can satisfy the requirements stipulated in the Chinese standard JGJ107-2003, JG171-2005.
4), High efficiency: Upset forging and threading one joint only needs no more than one minute, and handy operation and quick link.
5), Environmental protection and economy profit: No envirement pullution, can work all day, not affected by weather, economize energy source and bar material.
