Shengzao now mainly has two products ranges in cold pressure welding machine and dies. Our cold welding machine which we also called strip welding uses resistance welding process. The heat is generated by the passage of electrical current through the joint of the workpiece and the welding sheet. The heat is intelligently controlled to be large enough to fuse the material locally and form a nugget at the interface, and small enough not to anneal or quench the workpiece. This welding technique is better than conventional repair methods in many aspects.We now own metal defect mending machine,utrasonic mold polisher,intelligent repairing cold welding machine,screw extractor,hole-puncher..etc.We’ve been dedicated to providing the best solution for manufacturing enterprises to reduce cost and improve efficiency. 100% self design and production made “Lower cost&Lower price”of our products and machine processing.Well equipped,we guarantee good quality
