Upset forging straight screw thread connection technology (also named as upset forging parallel thread connection technology):
¡¡¡¡Reinforcing steel bar straight screw thread connection technology as the latest trend of reinforcing steel bar mechanical joint, which has become the base product of architecture structure in international market for it¡¯s ascendant impersonality condition, direct economy profit and handy operation method. We had stride a significant step of domestic existing reinforcing steel bar connection technology. The product became nowdays advanced technology of reinforcing steel bar which posses high strength of distortion reinforcing steel bar cool extrusion and that posses light, artful, quick, handy and also had beyond economy and society benefit connection technology.
¡¡¡¡We produce the reinforcing steel bar upset forging straight screw thread connection machines and coupler:
