ODM ANSI 150 ASTM B367 Titanium Alloy Casting

Titanium & Titanium Alloy Casting ANSI 150 ASTM B367

Cast of titanium material is a process of smelting and pouring titanium into castings under the condition of vacuum or protective gas. Titanium castings, mainly used in aerospace industry.The important parts are: engine compressor casing, intermediate casing, blade, hollow guide, inner ring, turbocharger impeller, bearing housing and support, aircraft support, silo, ear piece, short beam, flap slide, brake housing;Missile control module, tail fin, rocket rear head, common bottom, etc.;Satellite support, scanner frame, mirror barrel, etc.In civil industry is widely used in the manufacture of corrosion resistant pump body, valve, impeller;Screw propeller for ships;Precision machinery shell, bracket, cylinder body;Medical artificial joints, prosthetic limb components;Sports equipment for golf ball heads, harness, bicycle parts, etc. Including graphite mold casting and investment precision casting.Graphite moulding is the main moulding technology for producing civil titanium castings.And the processing of graphite type and graphite ramming type.Processing graphite mold is made of high quality artificial graphite block by hand or mechanical processing, according to the complexity of the casting mold, can use multiple live block combination, this casting mold can be used for many times.Graphite ramming type is made of artificial graphite sand and carbon organic binder rolled into the mixture, in the wood mold or metal mold sand box, with manual or mechanical modeling.The finished graphite sand mold is baked and dried at low temperature, and then roasted at high temperature under the cover of dry graphite powder or under the protection of non-oxidizing atmosphere.After making the mold combination, it can be loaded into the furnace for casting.Vacuum degassing treatment is required before casting for the aeronautical castings with strict quality requirements.Investment precision casting is the main process for producing titanium alloy castings with high precision, complex shape, smooth surface and compact interior.The investment casting method of titanium is basically the same as that of steel casting, except that there are some differences in shell making materials and some processes.
