Blown Core Manufacturing

Blown Core Manufacturing

Core blowers produce sand cores with an innovative inorganic binder system.

Inorganic cores are cured by applying heat through the tooling.

The core manufacturing, storage, and assembly takes place in an air conditioned core room. Controlled temperature and humidity are essential for a robust casting process.

Advantages of Inorganic Core Manufacturing:

  • Minimal emissions during core manufacturing and casting.
  • Elimination of condensation guarantees excellent process control.
  • Reduced core gas generation and increased design flexibility.
  • High initial strength: no deformation of the cores.
  • Minimal tooling maintenance.

During the product development phase and also for different design iterations blown cores may be combined with rapid prototype printed cores.
