What we do

Hand us the part. We will think of everything else.

Bring us a drawing, or only an idea, and the whole of the work becomes ours: the method and the metal, the pattern and the pour, the machining, the inspection and the delivery, all under one roof.

Sand casting

The craft we were founded on.

More than 50 years of sand casting behind each of our senior moulders

Some have made our moulds almost since the company began. Dedicated to the craft ever since, they sit down with your engineers over every drawing.

Casting

  1. Sand casting

    The process the company was founded on, and still the one it is known for. Our senior moulders read how a mould will feed, and where a heavy section will draw, before any metal is poured.

    Request a quotation
  2. Gravity die casting

    Metal poured under gravity alone into a permanent steel die: a denser, more consistent part than sand, with a finer surface straight from the mould. The natural choice once a design is settled and orders repeat.

    Request a quotation
  3. Investment casting

    Also known as lost-wax casting. A wax pattern is coated in ceramic and melted out, and the metal takes the precise shape it leaves, so fine features are cast rather than machined.

    Request a quotation

Around the pour

  1. Engineering & design

    Bring a finished drawing or only an idea. We model the part, review it for manufacture and recommend the metal and the method; where a small change would make it sounder, we propose it, and the decision stays yours.

    Request a quotation
  2. Patterns & tooling

    A good casting begins with a good pattern. Ours are made and maintained in our own pattern shop, so the hundredth casting matches the first, and a revision is taken on without waiting on anyone else.

    Request a quotation
  3. CNC machining

    The raw casting leaves our machine shop as a finished component, machined to the tolerances on your drawing and ready to assemble. With casting and machining under one roof, the machining allowance is settled when the mould is designed.

    Request a quotation
  4. Quality inspection

    Quality is built in at every stage rather than inspected in at the end. Parts are checked as they move through the works, what we find is recorded, and our quality management system is certified to ISO 9001.

    Request a quotation
  5. Packing & delivery

    Your parts are packed to arrive exactly as they left us, and delivered to your site, port or warehouse. Export shipping can be arranged on request.

Capabilities

What we can make for you

melting capacity: two furnaces of 750 kg each

Materials we cast

Five decades at the furnace have taught us how each metal fills a mould, feeds and cools. What each one is good for, and some of the parts we cast in it:

Grey iron

It machines cleanly, damps vibration and keeps its shape under load, which makes it the natural choice for machine bases, housings and pump bodies, and the most economical of the cast irons.

Parts we cast in it
  • Pump impellers
  • Pump casings
  • Bearing housings
  • Gears and pulleys
  • Machine bases

Ductile iron

Round (SG) graphite gives it much of the strength and toughness of steel while it still casts like iron, so it takes pressure and shock: valve bodies, pipe fittings and brackets.

Parts we cast in it
  • Gears
  • Couplings and hubs
  • Rolling-mill guides
  • Pump wear plates
  • Valve bodies

Steel

Carbon and low-alloy cast steels carry the heaviest loads, and can be welded and heat-treated, for parts that must not fail under impact.

Parts we cast in it
  • Sprocket wheels
  • Bogie wheels
  • Chain links
  • Bearing housings
  • Guide rollers

Stainless steel

Chromium-nickel grades resist corrosion in water, chemicals and food service, for pump, valve and marine parts that must stay clean and sound.

Parts we cast in it
  • Pump impellers
  • Pump casings
  • Pump body rings
  • Screw conveyor spirals

Aluminium

About a third of the weight of iron, it resists corrosion and machines quickly, and cast in permanent steel dies it holds sharp detail and a repeatable size.

Parts we cast in it
  • Housings and covers
  • Fan blades and hubs
  • Power-line grading rings
  • Brackets and clamps
  • Ship’s portholes

Brass & bronze

Copper alloys resist seawater and wear, and run smoothly against steel, which is why propellers, bushes, bearings and marine fittings are made in them.

Parts we cast in it
  • Pump impellers
  • Bushes
  • Stern tubes
  • Casing rings
  • Marine propellers

Quality

How we ensure quality

We inspect your parts through every stage, not only at the end, and keep a record of what we find. Our quality management system is certified to ISO 9001:2015.

  • Dimensional inspection against your drawing
  • Material and hardness testing
  • In-process checks at every stage
  • Documented quality records

Some of the equipment we work with

  1. Pinnacle LV117 CNC vertical machining centres

    Three Taiwanese-built machining centres on linear guideways, each with a 24-tool automatic changer. They machine your castings to finished size in our own shop, so they leave us ready to fit.

  2. ZEISS SPECTRUM coordinate measuring machine

    A CNC bridge-type coordinate measuring machine. It checks your parts in three dimensions against your drawing or CAD model and records every result, with glass-ceramic scales on all three axes and built-in vibration damping to keep its readings true.

    rated length accuracy, ISO 10360-2
  3. ZEISS VAST XXT scanning probe

    It scans along a surface instead of touching it point by point, so forms and profiles are measured in full rather than sampled. Its ruby-tipped styli on tungsten-carbide shafts reach small features down to a 1.5 mm tip.

    30–150 mm
    stylus lengths
    1.5 mm

  4. ZEISS RDS articulating probe head

    It turns the probe on two axes, ±180° each in 5° steps, so most faces of a part can be reached in a single set-up.

    probe positions
    5°

  5. ZEISS Multi-Sensor Rack

    The machine changes its own styli from the rack during a program, so a part with deep bores, small holes and flat faces is measured in one run.

  6. ZEISS CALYPSO measuring software

    Measuring programs are built straight from your CAD model, and every result is documented in a ZEISS PiWeb inspection report.

And many more machines to ensure the quality of our production.
