Four metals, three moulding methods, one site
We pour iron, aluminium and copper alloys, in green sand, resin-bonded sand or gravity dies, then machine, heat treat, blast and paint the castings without them leaving the works.
The alloy is a decision we make with you
Gray cast iron
Absorbs heat and vibration, wears evenly and machines easily.
Typical
Brake drums, pump housings, covers, machine bases
SG (ductile) iron
Spheroidal graphite gives strength and toughness under load and shock.
Typical
Axle tubes, wheel hubs, crankshafts, clutch plates
Aluminium alloys
Light and pressure-tight, poured in sand or in gravity dies. LM-6 is our most common grade; tell us if your drawing calls for another.
Typical
Steering housings, covers, thin-walled housings
Brass & bronze
Copper alloys where you need bearing properties or corrosion resistance.
Typical
Bushes, bearing shells, valve and pump components
Sand or die, chosen by what your job needs
Green sand moulding
Our everyday process for iron and aluminium: economical, quick to change over and well suited to repeat production.
Resin / no-bake moulding
Chemically bonded sand for a harder mould and a cleaner surface, used where the part is large, detailed or awkward to feed.
Gravity die casting
Permanent metal moulds, mainly for aluminium. Better surface finish, closer repeatability and less machining stock than sand, once the tooling is made.
What we arrange outside
We would rather name the boundary than let you discover it later.
- Casting processes we do not run ourselves, such as investment or pressure die casting, through foundries we work with
- Hardness testing and chemical analysis, at an independent laboratory
- Specialist coatings and plating
From pattern to painted, inspected part
Green Sand Casting
Our everyday moulding for iron and aluminium, including cored castings for housings and thin-walled parts.
Resin / No-Bake Moulding
Chemically bonded sand for a harder mould and a cleaner cast surface.
Gravity Die Casting
Permanent metal moulds for aluminium: finer finish, closer repeatability, less machining stock.
Gray Iron Castings
Damping-rich gray iron for drums, covers, housings and wear parts.
SG (Ductile) Iron Castings
Tougher spheroidal-graphite iron for load-bearing parts such as axle tubes, hubs and crankshafts.
Aluminium Castings
LM-6 and other aluminium alloys to your specification, cast in sand or gravity dies.
Brass & Bronze Castings
Copper-alloy castings such as bushes, bearing shells and valve components.
Turning
Shafts, bores, flanges and spigots turned to drawing.
Milling
Faces, pads and slots machined on the casting.
Drilling & Tapping
Hole patterns, threaded ports and spot-faced holes.
Heat Treatment
Annealing, normalising and stress relieving where the part or the drawing calls for it.
Shot Blasting & Fettling
Castings cleaned, gates removed and surfaces dressed before machining.
Painting & Primer
Primer or finish paint applied in-house, with machined faces left bare.
Pattern Development
Patterns and core boxes made in our own pattern shop from a drawing or a sample.
Reverse Engineering
Obsolete or imported parts measured and reproduced from a single physical sample.
Design Support
CAD and CAM in-house: the part is modelled and the toolpaths programmed before tooling is cut, so the casting and machining are agreed with you first.
Checked before it leaves the works
We check dimensions and casting soundness ourselves on every part. Hardness and chemical analysis are sent to an outside laboratory when a drawing calls for them: we do not run our own testing laboratory, and we would rather say so.
Dimensional Inspection
Calipers, micrometers and height gauges on the features that decide whether the part fits.
Visual & Soundness Checks
Surface and casting inspection for porosity, cracks and inclusions before a part is released.
Fit Against Your Sample
Where a part is reproduced from a sample, the finished part is compared back against it.
Laboratory Testing
Hardness and chemical analysis are arranged with an outside laboratory when your drawing calls for it. We do not operate an in-house testing laboratory.
Parts for everything that moves
Castings and machined components for automotive, tractor and motorcycle manufacturers, OEMs and the aftermarket.
