CAPABILITIES

Where the parts are actually made

Foundry, forging, machining, inspection and packing — the five stages every J&W order passes through, on shop floors we work with week after week.

  1. 01Design & Engineering

    Drawing review, material and process selection against your specification.

  2. 02CNC Programming

    Machine-specific programmes and tooling set before the first cut.

  3. 03Precision Machining

    Turning, milling, boring and grinding to drawing, checked in process.

  4. 04Quality Inspection

    Dimensional, chemical, hardness and surface checks with a report per lot.

  5. 05Packaging & Delivery

    VCI and anti-static protection, steel-reinforced crates, documents with the container.

Lost foam casting line

Foundry

Five casting routes under one network — resin sand, V-method, lost foam, ceramic shell and heat treatment. We pick the route that suits the wall thickness, the tolerance and the volume, not whichever line happens to be free.

V-method moulding line Resin sand moulding

Castings up to 500 kg · flasks 650×750×200 and 508×610×400 mm · grey iron, ductile iron, cast steel, high chrome iron and ceramic.

Ring and sleeve forgings

Forging

The forging route runs alongside the foundry: closed-die and upset forgings in carbon and alloy steel, normalised or quenched and tempered, then machined on the same CNC line and inspected to the same standard.

Heat treatment before machining Machining of forged blanks

Ring, sleeve and shaft forgings · carbon steel, alloy steel and stainless steel.

CNC horizontal boring and milling machines

Machining

More than 100 machine tools across the partner shops, most of them CNC: vertical and horizontal machining centres, large vertical lathes, boring mills, cylindrical and surface grinders. Big work stays on big machines.

Machining hall with vertical machining centres Vertical machining centre

Shafts to 6 m · bores to 1.6 m · turning, milling, boring, drilling and grinding in one route.

Coordinate measuring machine

Inspection

Every order is checked where it is made: incoming material at the manufacturer, in-process checks at the machine, then a final dimensional and visual inspection before packing.

Hardness testing Finished parts before dispatch

Reports and material certificates travel with the shipment.

Export packing yard

Packing & export

Parts are packed for the sea freight they will actually travel on — VCI film and anti-static wrapping where the material needs it, steel-reinforced export crates, marking to your requirement, and a complete document set with the container.

Export crate Finished castings awaiting dispatch

We book the container and follow the shipment through to the port of discharge.
