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 cast 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.

Up to 50 mm 254 mm
Up to 75 mm 381 mm
Up to 100 mm 508 mm
Up to 125 mm 635 mm
Up to 150 mm 762 mm

Flatness :

Flatness refers to single plane surface and is usually a function of volumetric shrinkage.
