For 20 years, we has been specialising in the design and manufacture of cold welding equipment and dies for wire and cable industry. The cold pressure welding machine is a fast, easy and cost-effective method of bonding non-ferrous wire and strip to provide a bond stronger than the parent material, without heat, fillers or fluxes, which can join copper wires from 0.07mm to 8.00mm, aluminum wires from 0.07mm to 14.00mm. Certainly the unit pirce of our cold pressure welder are better than pwm similar products.
