— Stage-Gated Foundry Workflow

Every stage documented. Every casting traceable.

From pattern approval to dispatch, each step carries a defined check. Nothing moves forward until the previous gate is cleared and recorded.

/ How We Run It

Five stages, zero skipped steps

01 — Pattern & Tooling

02 — Moulding

03 — Melting & Pouring

Drawing review before any tool is cut

Sand preparation and mould assembly

Alloy composition verified at the furnace

Each drawing is reviewed for castability and tolerance feasibility. Dimensions are confirmed against the pattern before moulding begins.

Charge composition is logged per heat. Pouring temperature is recorded against the alloy spec for every mould in the batch.

Sand mix ratios are tested per batch. Mould hardness and cavity dimensions are checked before the mould is closed.

04 — Fettling & Finishing

Gates removed, surfaces dressed to drawing

Risers and gates are cut, parting lines are dressed, and critical dimensions are re-checked against the drawing before the part proceeds.

05 — Inspection & Dispatch

Dimensional and visual check before every shipment

Each batch is inspected against the drawing. Reject counts are recorded. Only cleared castings are packed and dispatched with a batch record.

The full stage-gated workflow: what happens at each step, what is checked, and what records are kept before the part moves forward.

Alloy grades sourced and certified per batch. Spec sheets, composition ranges, and traceability records for every material we pour.

Equipment list, plant layout, and production capacity at the Lothada site — enough detail to assess capability before arranging a visit.
