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.
