Lost Wax Casting Process
Xi'an GX Mechano-Electronic Co.,Ltd is a leading China lost wax casting process manufacturer and supplier,Website:, and also a professional lost wax casting process foundry, factory and company, please feel free to contact us at any time.Lost wax investment casting is a process that uses molds to form liquid metals. During this process, liquid metals are shaped into high quality products that are made of many different types of metals. Because lost wax casting often results in rough finishes, additional procedures may be needed to remove burrs from the end products. The process is generally used for small castings, but has produced complete aircraft door frames, steel castings of up to 300 kg and aluminium castings of up to 30 kg. It is generally more expensive per unit than die casting or sand casting but with lower equipment cost. It can produce complicated shapes that would be difficult or impossible with die casting, yet like that process, it requires little surface finishing and only minor machining.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 etc4Tolerancecasting: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 0.1~0.15Lost wax investment casting process : mould design -open mold- injection wax (die) - finishing wax models (welding) -wax models - wax tree (weighing) - making shell mold- mold shell roasting - pouring - pouringshell – cleaningIntroduction: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.
