VTHK -350 Vacuum Coating Machine mainly carry out thermal treatment of materials in high vacuum environment. They are very suitable for bright annealing of silicon-steel plates, soft-magnetic materials, electrician malleable cast-iron, copper alloy; for bright annealing of high-speed steel, die steel, tool steel, alloy steel, titanium alloy; removing the residual stress of forge piece, welding piece,? cool punching piece, and workpiece punching, so as to defend the distortion and crazing of the workpiece. Our equipments have high-accuracy, high-stability, high-reliability, and long working time. They are very suitable for scientific research and education and for the large-scale development of new commercial products.
