Molding sand preparation with air cooling

Molding sand for the efficient production of castings

State-of-the-art compacting technology for sand molds can make a significant contribution to casting efficiency provided that the molding sand consistently meets stringent quality criteria.
The most important quality criteria for molding sand are:

  • Exact compliance with compactibility specifications
  • Excellent flowability
  • Uniform strength values
  • Optimal gas permeability

The EIRICH mixing system is ideally suited to meet this requirements profile:

  • Perfect homogenization of return sand, new sand and additives
  • Fast, complete distribution of the water which is added to the mix
  • Sufficient duration of the wet mixing phases
  • The bentonite is completely dispersed and forms a uniform coating on the grains of sand

The EIRICH mixing system with its unique advantages produces top quality sand with excellent reproducibility.


Molding sand preparation under vacuum – the EVACTHERM® process

EVACTHERM® – for the highest demands on efficiency and quality

What requires three process steps with the air cooling method – cooling, mixing and bentonite activation – now takes place in just a single step in the EVACTHERM® molding sand mixer. Cooling and bentonite activation are integrated in the mixing process.
Originally developed as a cost-effective cooling solution, the EVACTHERM® process has been specifically adapted for molding sand preparation applications. Today, it is the solution of choice wherever there is a need for outstanding efficiency and quality.
