Address: 1506 Ring Road, Kunshan (339 provincial highway and Huanqing Road intersection 200 meters north)
▲ GMT-explosion-proof base wire welding> 0.5 ~ 2.4mm HB ~ 300 high-hardness steel joints, hard surface production of the base, crack welding. High-strength welding, high nickel-chromium alloy composition for the anti-cracking bottom welding, filling primer, strong pull, and repair of steel welding rebuild the crack.
▲ GMT-718> 0.5 ~ 3.2mm HRC 28 ~ 30 large appliances, toys, telecommunications, electronics, sports equipment and other plastic products die steel. Plastic injection mold, heat-resistant mold, corrosion-resistant mold, machinability, erosion good, excellent surface gloss after grinding, long service life. Preheat temperature of 250 ~ 300 ℃ after the hot temperature of 400 ~ 500 ℃, for multi-layer welding repair, the use of back-welding method, less prone to poor fusion and other defects.
▲ GMT-738> 0.5 ~ 3.2mm HRC 32 ~ 35 Semitransparent and need to have the surface of the plastic mold steel products, large molds, complex shapes and high precision plastic mold steel. Plastic injection mold, heat-resistant mold, corrosion-resistant mold, etching good, with excellent processing performance, easy cutting and polishing, and electrical erosion, toughness and wear resistance. Preheating 250 ~ 300 ℃ after the hot temperature of 400 ~ 500 ℃, for multi-layer welding, the use of back-welding method, less prone to poor fusion and other defects.
▲ GMT-P20Ni> 0.5 ~ 3.2mm HRC 30 ~ 34 plastic injection mold, heat-resistant mold (copper mold). Welding alloy with a low sensitivity to cracking design, nickel content of about 1%, suitable for PA, POM, PS, PE, PP, ABS plastic, with good polishing, no pores after welding, cracks, Kunshan hot work die steel After grinding there is a good finish, the vacuum degassing, forging, pre-hardened to HRC 33 degrees, section hardness uniform distribution, mold life of 300,000 or more. Preheat temperature of 250 ~ 300 ℃ after the hot temperature of 400 ~ 500 ℃, multi-layer welding repair, the use of back-welding method to repair, less prone to poor fusion and other defects.
▲ GMT-NAK80> 0.5 ~ 3.2mm HRC 38 ~ 42 plastic injection mold, mirror steel. High hardness, good mirror effect, good discharge processability, excellent welding performance, after grinding, smooth as a mirror, the world's most advanced, the best plastic mold steel, adding easy to cut elements, cutting easy, with high strength and toughness and resistance No deformation characteristics of the mill, suitable for a variety of transparent plastic mold steel products. Preheating temperature 300 ~ 400 ℃ after the heat temperature 450 ~ 550 ℃, for multi-layer welding, the use of back-welding method, less likely to produce poor fusion and other defects.
▲ GMT-S136> 0.5 ~ 1.6mm HB ~ 400 plastic injection mold, corrosion resistance, good permeability. High purity, high specularity, good polishing, excellent anti-rust and anti-acid ability, less heat treatment deformation, suitable for PVC, PP, EP, PC, PMMA plastic, corrosion-resistant and easy-processing modules and fixtures, Precision molds, such as rubber molds, camera parts, lenses, cases and more.
