Advantages of investment casting products:
· Flexible Size and Weight Range:
The investment casting process can produce casting products exactly according to the drawings and mold made, casting weight is from 0.5kgs to 80kgs,meeting various demand for various industries.
· Versatile and intricate shapes:
With the precision mold made , Investment casting processing provides casting components with consistent and repetitive close tolerances along with intricate passages and contours, while many of these can not be finished by machine tools.And the investment casting processed cast parts can obtain net shape or near net shape components easily.
The technician will consider the work efficiency of the processing during design period, and many metal components are combined into a single casting, in this way, the investment casting components typically reduced part complexity and delivers more dimensional accuracy. It is a kind of good alternative to welding or fabricating.
· Accurate and Smooth Surfaces:
The silica sol shell is used during the investment casting process to build smooth patterns produced by injecting wax into a polished aluminum die to achieve a finer surface quality. If surface required not so high, another investment casting processing sodium silicate shell can help to build components with its favorable cost. Investment castings contain no parting line because only one mold is used. Standards of surfaces blemishes and cosmetics are discussed and agreed upon with the customer based on the function.
· Dimensional Accuracy:
The cost of any part increases in proportion to the preciseness of its dimensional requirements. A close design review will permit modification to tolerances, undercuts, blind holes, etc. to allow higher production yields and lower piece costs. If closer than cast tolerances are necessary, the machining required for investment casting will be less than conventional castings or fabricated components.
· Quality and Integrity:
Casting integrity is an important feature of the investment casting process. Investment casting has a long history of serving demanding industries such as automotive, marine, petroleum, oil & gas, chemical, defense, medical, gas turbine engine, and various industry.
Investment Casting Process:
Wax injection—Wax pattern— Repair wax—Wax inspection—Group tree—Shells make (first paste, sand,re-slurry, drying)—De-waxing—Mold roasting— Chemical analysis—Casting (pouring molten steel)—Vibration shells—pouring of casting and pouring rod—Grinding gate—Initial inspection (hairy inspection)—Shot blasting—CNC Machining—Polishing—Finished inspection—Packing.
