Tooling and Simulation
Patterns are designed in CAD and the filling and solidification are simulated in AutoCAST before any metal is cut.
What Customers Tell Us After a Plant Visit
One Stop
Solution
Most foundries pour the metal and send the casting out again to be heat treated, machined and coated. Every one of those steps happens here at Arasur. That means one purchase order, one quality system and one company answerable for the finished part, instead of a chain of suppliers where lead time and accountability get lost.
Casting
Five moulding routes — high pressure, ARPA 450, ARPA 1300, shell and Alpha-set No Bake — covering 1 kg to 1,500 kg in a single piece.
Heat Treatment
Stress relieving, normalising, annealing, hardening and tempering, and induction hardening, all on site, so parts are treated without leaving the plant.
Machining
Twenty vertical machining centres, four horizontal centres, thirteen turning centres, five VTLs and a vertical turn mill to 1,750 mm.
Fabrication and Assembly
TIG, MIG and arc welding, sheet perforation and forming, and sub-assembly with bought-in steel, brass, PTFE and rubber components.
Testing and Finishing
Spectrometer, CMM, ultrasonic and magnetic particle inspection, pressure and load testing, and primer paint applied in house.
How We Work
From Drawing
to Delivery
Every casting takes the same route through the plant, with a defined check at each stage.
Tooling and Simulation
Patterns are designed in CAD and the filling and solidification are simulated in AutoCAST before any metal is cut.
Core Making
Cold box, shell and CO2 cores are shot to size in a core shop running shooters from 5 kg to 30 kg.
Moulding
The part is routed to high pressure, ARPA 450, ARPA 1300, shell or Alpha-set No Bake, according to its size and volume.
Melting and Pouring
Four 1 tonne dual-track induction furnaces melt around 60 tonnes a day, with chemistry set on an ARL spectrometer before each pour.
Fettling and Finishing
Castings are knocked out, fettled and ground to size, then stress relieved, normalised or hardened in our own heat treatment shop where the grade calls for it.
Machining and Inspection
Parts are machined on the VMC, HMC, turning and VTL lines, measured on Brown & Sharpe CMMs and tested against the drawing.
Painting and Packing
Primer paint is applied in house, with CED, powder, zinc and galvanize finishes through approved partners, then parts are packed to the agreed standard for road or sea freight.
Equipment and Capacity
The Plant Behind
the Promise
One stop only works if every station is properly equipped. Installed capacity is 1,500 tonnes a month, and more than forty machine tools sit on the same site as the furnaces.
Melting and Capacity
Four 1 tonne dual-track medium frequency induction furnaces melting around 60 tonnes a day, plus a dedicated bay of two 1.5 tonne furnaces feeding the No Bake line.

Five Moulding Lines
A DISA MATCH 130 high pressure line at 100 to 120 moulds an hour, ARPA 450 to 100 kg, ARPA 1300 to 550 kg, a shell line, and Alpha-set No Bake for the largest work.

Low, Mid and High Volumes
A single prototype and a ten-thousand-piece programme
run in the same plant.
We match the moulding route to your quantity.
Flexible to Fit Your Order
Which Line Suits
Your Quantity
Five moulding routes exist for one reason: a part you order once a year and a part you order every week should not be made the same way. Tell us the annual volume and we will put it on the right line.
| Volume Band | Route We Use | What It Suits |
|---|---|---|
| High volume | DISA MATCH 130 high pressure line, box 510 x 610 x 400 mm, 100 to 120 moulds an hour | Repeat automotive and powertrain parts up to 50 kg, where piece price and repeatability decide the order |
| High volume, fine finish | Shell moulding line, resin-coated sand | Smaller parts that need a better as-cast surface and tighter dimensional consistency |
| Mid volume | ARPA 450 (box 650 x 700 x 400 mm) and ARPA 1300 (box 1,200 x 1,000 x 700 mm) | Steady but not continuous demand, single pieces to 100 kg and 550 kg |
| Low volume and one-offs | Alpha-set No Bake — fast loop line 1,600 x 1,200 x 700 mm, floor moulding 2,000 x 2,000 x 700 mm | Large, infrequent or trial castings up to 1,500 kg, including prototypes and spares |
| Assembly | Sub-assembly and load testing bay | Low and mid batch volumes, built up with bought-in steel, brass, PTFE and rubber parts |
Materials
Three Metal Families
Around 60 per cent of our output is ductile iron, 30 per cent grey iron and 10 per cent steel.
Grey Cast Iron
EN-GJL-250 to EN-GJL-300
Chosen for damping and machinability. Poured to EN 1561 and cross-referenced to GG30 and GG35, FGL 250 and 300, ASTM A48 and JIS FC grades. Around 30 per cent of output.
Ductile (SG) Iron
EN-GJS-400-18 to EN-GJS-900-2
The largest share of our output at roughly 60 per cent. Chosen where a part must carry load without cracking, with nodularity confirmed by ultrasonic velocity inspection.
Steel Castings
Carbon, alloy and stainless grades
About 10 per cent of output, including WCB carbon steel, alloy steels such as 20MnCr5 and E350, and stainless grades such as CF3M for corrosive service.
