As well as a good moulding machine, the quality of the sand is crucial in determining the quality of the cast pieces.

Sand preparation includes the following:

  • preparing the necessary amount of sand
  • screening out lumps and metallic impurities
  • homogenizing the spent sand
  • freshening up the sand in response to the stress from the casting process
  • ensuring precision in the addition of new sand, bentonite, coal dust and filter dust, as well as adding water for cooling and moistening

We create an individualized layout according to the client’s wishes and the process requirements. The proposal is discussed with the client, and is adapted to their wishes. The result is an optimized tailored plant design.

We manufacture all key components of sand preparation ourselves, such as return sand coolers, moulding sand mixers, and polygonal screens. This way, we ensure that all the knowledge both from our manufacturing process and from our clients`operating experience feeds into the continuing further development of our products.
