Casting Fixtures

Scope and process

Engineering workflow for casting fixtures at Dahegam, Gandhinagar, Gujarat, India: 3D CAD modeling of part workholding envelope → FEA clamping force and deflection analysis → CNC machining of hardened baseplates and locator nests → grinding of locating dowels and wear pads → laser CMM verification of critical datum points.

Materials we work with

Adjustable supports and equalisers, with clamping placed to avoid springing a thin cast wall. Body material is chosen for the duty — tool steel where wear or heat is the issue, aluminium where the fixture must be lifted by hand.

Tooling support

Locates on cast datums with adjustable or self-levelling pads that absorb casting variation.

Choosing the right option

When requesting a proposal for casting fixtures, please provide component 3D CAD models (STEP/IGES), 2D part drawings indicating critical datums, machine table specifications (T-slot pitch, pallet size), and target cycle time. Quotes with 3D concept layouts are issued within 24 hours.

Quality checks and inspection

On a fixture the check that matters is machining allowance remaining on the worst-case casting, checked on first-off. Dimensions are verified on CMM against the fixture drawing before despatch.

Commissioning and handover

Handed over after a first-off on a worst-case rough part, so remaining machining allowance is proven.

Export packing and lead time

Ships with adjustable supports set and their positions recorded. HEMSUN is a DGFT IEC registered exporter (Government of India); commercial invoice, packing list and certificate of origin accompany international despatch.

Maintenance and spare parts

Adjustable supports drift under repeated clamping; re-verify their settings at a planned interval.
