Advantages
Choice of Alloy selection :
Practically any alloy can be investment cast wide range of ferrous alloys are regularly cast at Maitri Cast Pvt. Ltd.
Design Flexibility :
Almost any shape or complex can be investment cast. Investment casting offers designers freedom of design in wide range of alloys with close dimension tolerances and fine details.
Cost Reduction :
Investment casting offers a near net shape then reducing or eliminating costly machining operations.
Increase manufacturing Capacity :
As almost final shape is available on investment casting, machine tools are released for finish machining operations.
Cut Assembly Operations :
Complex assemblies can be cast as per single unit reducing handling, assembly and inspection cost.
Casting Capability :
Casting weight from 2 gms to 10 kg can be cost at TPPL. Max. casting size 14″ x 16″.
Casting Tolerance :
This tolerances apply as a general rule of thumb. Closer tolerances can be obtained depending on part design or the use of special procedures or secondary operations.
