Leak Testing Fixtures

Scope and process

Engineering workflow for leak testing 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

Sealing faces and a seal set chosen for the test medium, with quick clamping for cycle time. 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 and seals against machined faces or port bores with replaceable elastomer seals.

Choosing the right option

When requesting a proposal for leak testing 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 fixture-side leak rate on a known-good master before the part result is trusted. Dimensions are verified on CMM against the fixture drawing before despatch.

Commissioning and handover

Handed over with a master-part run so the fixture’s own leak or signal baseline is established before production parts are judged.

Export packing and lead time

Ships with the seal set fitted and a spare set, plus the connection schedule. 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

Seals are the wear item and drift slowly; re-baseline against the master part on a fixed schedule.
