Development, production and treatment of casts
Cold Box procedure
Development

Development is of primary interest. Our work includes Catia 3D modelling and ProCast simulation.

Melt preparation and treatment

The melt preparation and treatment, as they are of key importance for the quality of casts, are given great attention. We apply:
  • Degassing of foundry alloys with Argon in the impeller and
  • Modification with strontium and titanium-boron.
Casting

We use casting machines for gravity die casting and for low-pressure die casting. We manufacture casts with or without core in weight from 0,5 to 30 kg.
 
Decoring & Deburring

Different procedures are used for cleaning casts:
  • Removal of sand cores,
  • Removal of sprues and burrs in robotized cells,
  • Machine grinding,
  • Manual grinding,
  • Sandblasting.
Thermal treatment

According to the demanded mechanic properties we apply a thermal cast treatment (T3, T4 up to T6).

Mechanic treatment

CNC tooling runs on modern CNC machining centres.
 
By using a sand core that is inserted in the mould before the casting process a cavity is designed in the cast.
Sand cores
The accurate form of the Cold Box core enable accomplishment of hollow castings of most complex shape.
