Foundry Industry
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:
Greater manufacturing efficiency
Quick cleaning without the need for dismantling or cooling-off periods.
Residue-free cleaning
No contamination of the castings or the moulds.
Gentle cleaning
No signs of abrasion, no damage to the moulds or castings.
No secondary waste
No water, no chemical cleaning products, no dirty water.
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.
Safety and CO₂ Management
In foundry production, safety when handling CO₂ is essential. CO₂ safety detectors, storage tanks and optional CO₂ recovery systems from ASCO ensure the safe, efficient and sustainable use of CO₂ in production.
Clean Moulds. Efficient Production. High-Quality Castings.
Whether it’s mould cleaning, deburring, surface preparation or plant cleaning – with dry ice and CO₂ solutions from ASCO, foundries benefit from maximum process reliability, consistently high casting quality and maximum efficiency.
