Xi'an GX Mechano-Electronic Co.,Ltd is a leading China metal molding green sand casting manufacturer and supplier,Website:://.xagx-casting.com, and also a professional metal molding green sand casting foundry, factory and company, please feel free to contact us at any time.After preparing the sand mould, and the metal has reached a molten state in the crucible, it is then ready to pour. When the crucible full of molten metal is carefully removed from the furnace with a pair of special lifting tongs and placed into a well designed pouring shank, wearing the proper safety gear you take hold of the pouring shank which cradles the crucible, then quickly pour the molten metal into the sprue of the sand mould. After the metal cools down, the mould boxes can be pulled apart to reveal the bright new metal art casting - vintage car or motorcycle part, or perhaps a reproduction part for an old machine of some kind, the things that you can make with metal casting is endless.1materialCopper  alloy, aluminium alloy, stainless steel, ordinary carbon steel, heat resistant steel, high chromium alloy, high nickel alloy, hartz alloy, etc.2processsand   casting, precision casting, investment casting, lost wax casting, die  casting, forging, stamping, machining etc3machinelathe, CNC, drilling machine, milling machine, boring machine, planting machine, machining center etc.4tolerancecasting:0.5mm,  machining:0.05mm, finish machining:0.005mm5capacitymax diameter:1M, max weight:200KG6surface treatmentpowder  coating, painting, spraying, galvanization7standardJIS, ANSI, DIN, BS, GB   Casting   materialThicknessLengthLength/width(ratio)Woodcasting’s  thickness  contraction rate10mm-3m≤100Aluminium3.0mmSteel2.5mmCopper2.5mm  Parts typeThe extent of thequartz sand（mm）The compressed air pressure (mpa)≥3   mm thick large iron and steel parts2.5~3.50.3~0.51 ~ 3 mm   thick medium steel parts1.0~2.00.2~0.4Small thin   brass casting0.5~1.00.15~0.25≤ 1   mm thick steel sheet metal parts, aluminum alloy parts≤0.5 0.1~0.15Our production ability :Our factory has 5 large sand casting production line ,30 small sand casting foundry work platform, 2 sand casting workshop, the biggest can complete 100 kg/pc casting; A casting workshop equipped with 6 sets of gravity casting equipment.
