Everything that decides the life of a casting

From the method to the machined part, in our own plants.

One supplier. One manufacturing chain. One responsibility.

From your problem to the finished part, every step that decides the life of a casting is ours to control and ours to answer for.

*Casting simulation for critical parts is run with a specialist partner; method design is in-house.

01

Engineering and method

Every new part starts with a method: gating, risering and feeding designed in-house, with casting simulation through a specialist partner for critical parts. Worn parts and samples are reverse-engineered when no drawing exists.

  • Methoding and casting design
  • CAD and profile design
  • Reverse engineering from samples
  • Simulation with a specialist partner
02

Pattern shop

Patterns are made in-house in wood, polystyrene and aluminium, cut on a CNC router. More than 10,000 patterns are already on file, so repeat orders go straight to moulding.

  • 10,000+ patterns on file
  • Wood, polystyrene and aluminium
  • CNC router pattern making
03

Melting

Induction melting in crucibles from 500 kg to 6 tonnes. A dual-track power supply brings up to 10 tonnes of liquid metal to a single pour, so heavy pieces are cast in one go.

  • Crucibles of 500, 1,500, 3,000 and 6,000 kg
  • Up to 10 tonnes of liquid metal per pour
  • Spectrometer analysis on every heat
04

Moulding

Alphaset no-bake moulding gives strong, dimensionally stable moulds for pieces from 3 kg to 7 tonnes. Sand is mechanically reclaimed and reused.

  • Alphaset mixers of 8 and 20 tonnes an hour
  • Mould pre-heater and shell core shooter
  • Sand reclamation of 6 and 12 tonnes an hour
05

Heat treatment

Gas-fired box furnaces with water quench and bogie-hearth furnaces with air and oil quench. Manganese steel goes from furnace to water in about 45 seconds.

  • Two 10-tonne box furnaces, water quench
  • Two 12-tonne bogie-hearth furnaces, air and oil quench
  • Solution treatment, hardening and tempering
06

Fettling and machining

Castings are fettled, proof-machined and finished to drawing on CNC and conventional vertical lathes, machining centres and a 6,500 mm special-purpose machine.

  • Two CNC vertical lathes and a 1,350 mm VTL
  • Machining centres to 1,600 × 800 mm
  • Plano miller, lathes and radial drills
