We are a leading shear stud connectors manufacturers in China.We have exported 600X20″GP shear studs to oversea market in last year.
Cold heading machine mainly on the pier is dedicated to the mass production of shear connectors,bolts, fasteners, such as special equipment.
Apply to the bearing, nail and after carburizing and quenching tempering treatment of mechanical parts.
Automatic multi-stage cold fromer
The multi station automatic cold heading machine automatically upgrades various high strength bolts by means of cold heading.
Rolling machine is a multi-functional cold extrusion forming machine. Rolling machine can roll threads, straight lines and twill lines of workpieces in the cold state within the range of rolling pressure. High Strength ASTM A325 Hex Bolt
Straight strip cutting of large size, high strength material.refers to the need for deformation after heating, generally equal to larger bolts.
Corner of the workshop
The company has more advanced production equipments, more than 100 skilled workers.8 production lines.
Red beat machine
The company has more red beat machines,refers to the need for deformation after heating, generally equal to larger bolts.
