Efficient cleaning and process optimisation using dry ice

Clean Moulds, Efficient Processes, High-Quality Castings

In the foundry industry, cleanliness, precision and efficiency play a central role. Residues of sand, release agents, oxides or casting adhesions can reduce the quality of castings, increase tool wear and lead to production downtime. At the same time, moulds, tools and equipment must be cleaned regularly without being damaged or requiring the use of chemical cleaning agents.

ASCOJET dry ice blasting machines provide the foundry industry with an efficient, gentle and residue-free cleaning solution that optimises production processes, extends tool life and ensures the quality of castings.

Mould and Tool Cleaning – Precision Without Downtime

The cleaning of sand moulds, metal moulds or casting tools is crucial for consistently high-quality castings. Deposits of sand, oxides, release agents or casting residues lead to dimensional deviations, surface defects and increased tool wear.

With ASCOJET dry ice blasting machines, moulds can be cleaned directly in the production area – without removal or dismantling, quickly and efficiently. The dry ice sublimates without leaving any residue; there is no secondary waste, no water and no chemical residues, meaning the moulds are ready for use again immediately.

Deburring and Demoulding – Clean Components with the Highest Precision

After casting, castings often need to be deburred or cleaned of sand residues. Conventional methods such as grinding, brushing or chemical cleaning are time-consuming, generate waste and can damage the surface of the castings.

Dry ice blasting removes burrs, oxides and residues precisely and evenly without altering the material structure. This improves the surface quality of the castings, maintains dimensional accuracy and significantly reduces the need for post-processing

Surface Preparation – The Ideal Foundation for Coatings

Before applying protective coatings, paints or thermal insulation materials, cast surfaces must be free of deposits, oil or release agent residues. Dry ice blasting thoroughly prepares the surface without damaging it and guarantees ideal adhesion for subsequent coatings.

Plant and Conveyor Belt Cleaning

In addition to moulds, foundry equipment, conveyor belts, casting stations and melting furnaces must also be cleaned regularly. Dry ice can be used to remove burnt-on residues, metal oxides, grease or castings quickly and without leaving any residue – even in hard-to-reach places.

Cleaning is carried out dry and without water, meaning production equipment can be put back into operation immediately. This minimises downtime and increases overall production efficiency.

Advantages of Dry Ice Blasting in the Foundry Industry

The use of dry ice in foundries offers numerous advantages:

Icon for fast and efficient operations in CO₂ plants, dry ice production or cleaning technologies that enable short process times, optimised resource use and high productivity.

Greater manufacturing efficiency

Quick cleaning without the need for dismantling or cooling-off periods.

Sparkling icon or surface representing cleanliness and cleaning

Residue-free cleaning

No contamination of the castings or the moulds.

Icon for material-friendly processes such as dry ice blasting or CO₂-based cleaning, in which surfaces are cleaned effectively without damaging their structure or coating

Gentle cleaning

No signs of abrasion, no damage to the moulds or castings.

Icon for industrial cleaning processes such as dry ice blasting or CO₂-based cleaning, in which dirt, residues and contamination are removed from surfaces efficiently and gently.

No secondary waste

No water, no chemical cleaning products, no dirty water.

Shield with a check mark as an icon for safety and protection in industrial processes

Improved casting quality

Clean moulds and surfaces ensure consistent dimensional accuracy and surface finish.

Versatile

Cleaning carried out on site, even in hard-to-reach areas.

In-House Dry Ice Production – Flexible and Cost-Effective

For foundries that regularly require dry ice for cleaning processes, having their own on-site dry ice production is worthwhile. With ASCO dry ice machines, the required medium can be produced at any time to meet specific needs – in the right form, quantity and quality.

The Carefree rental option allows you to respond flexibly to production peaks or fluctuating cleaning volumes without high investment costs. This saves on logistics costs and guarantees a constant supply of fresh, high-quality dry ice.
