Thirty Years of Cold Pressure Welding in Shunde Foshan
Silver Gain Technology Co., Limited specialises in the manufacture of cold pressure welding machines, welding dies, copper conductor and cable welding machines, electric butt welding machines for steel, and related wire and cable machinery. The company has been doing this for 30 years, and its products have a good reputation at home and abroad.
What Cold Pressure Welding Does
Cold pressure welding is an economic and effective way to join non-ferrous metals and their alloys without heat, fillers or fluxes. It creates a weld as strong as the parent material with the same electrical characteristics. SGT builds three machine families for it — portable, desk and hydraulic pressure car style — covering copper wire from Ø0.05 mm to Ø25.00 mm and aluminium wire from Ø0.05 mm to Ø50.00 mm.
The Die Programme
SGT welding dies are the industry standard type and can be customised to the specifications of special wire. They also fit comparable cold pressure welders from other manufacturers, so a plant does not have to change machines to change die supplier.
Export Markets
SGT cold welding machines and conductor and cable welding machines are exported to many countries. Buyers cite quality, competitive price and after-sales service.
What We Commit To
Credit quality is the foundation of success. We are committed to better products that meet the top quality standard of the global market.
