Dry ice blasting in mechanical engineering: cleaning machines without downtime
Industrial machine cleaning by dry ice blasting, without dismantling and without production downtime. Up to 95% less downtime than conventional methods.
Mechanical engineering: dry ice blasting
In mechanical engineering, every hour of downtime costs hard cash. Conventional cleaning methods often require the equipment to be fully dismantled, cool-down periods lasting several days and the use of aggressive solvents, with the resulting production losses and disposal costs.
Dry ice blasting eliminates this downtime almost entirely. The process cleans machines, tools and production equipment in situ. No dismantling, no cool-down, no solvents. The CO₂ sublimates on impact, so no moisture reaches sensitive bearings, seals or electronic control systems.
For production managers, this means cleaning can be carried out during planned maintenance windows, at weekends or even during operation. Documented results show a 50 to 95% reduction in cleaning time compared with manual methods, with better results at the same time.
Typical applications:
Mechanical engineering
Dry ice blasting solves industry-specific cleaning tasks where conventional methods reach their limits.
Injection moulds & tools
Release agent residue, deposits and outgassing residue are removed directly in the machine, with no cool-down and no mould wear. Cleaning takes under 15 minutes per mould.
CNC machines & machining centres
Coolant residue, swarf and oil mist deposits are removed precisely without damaging sensitive guideways or measuring systems.
Welding robots & paint lines
Weld spatter, paint mist and adhesive residue are removed from robots and conveyor systems, even in hard-to-reach areas.
Hydraulic systems & gearboxes
Oil and grease deposits on hydraulic blocks, gearboxes and drive units are removed without damaging seals or surfaces.
Conveyor belts & packaging lines
Product residue, adhesives and label remnants are removed from conveyor belts and packaging machines, which is also possible during operation.
Control cabinets & control systems
Dust, oil mist and early signs of corrosion are removed from control cabinets. Dry ice is electrically non-conductive, so there is no need to remove the electronics.
Mechanical engineering: why dry ice?
Mechanical engineering: these industry-specific benefits make dry ice blasting the most efficient cleaning solution.
Cleaning in situ
Machines do not have to be dismantled. Injection moulds stay in the machine, robots in their cell, conveyor belts in the line. This saves assembly time and eliminates the risk of damage during removal and refitting.
Up to 95% less downtime
Documented results from the automotive supply industry: the cleaning time for an injection mould was reduced from 8 hours (manual) to 25 minutes (dry ice). The machine keeps producing instead of standing idle.
No solvents, no waste water
Unlike chemical cleaners, there are no disposal costs for solvents or contaminated waste water. The CO₂ sublimates without residue, leaving only the loosened dirt behind.
Non-abrasive: gentle on precision surfaces
With a Mohs hardness of 2, dry ice is softer than any metal. Polished tool surfaces, sealing surfaces and fits remain undamaged: no micro-scratches, no material removal.
Electrically non-conductive
Control systems, sensors, cable harnesses and electric drives can be cleaned directly. No risk of short circuits, unlike high-pressure cleaning or wet cleaning methods.

| Surface protection | Non-abrasive (Mohs 2) | Risk of scratching | Chemical reaction possible |
| Disposal costs | None (sublimates) | Cloths/cleaning agents | Hazardous waste disposal |
| Suitable for electronics | Yes, non-conductive | Limited | No |
Mechanical engineering: FAQ on dry ice cleaning
Mechanical engineering: answers to the most frequently asked questions about dry ice cleaning.
Can’t find your question?0800 0010982 · Mon to Fri, 7:00 to 18:00Yes. Dry ice has a Mohs hardness of 2, which makes it softer than copper, aluminium or steel. Polished tool surfaces, sealing surfaces and precision parts remain undamaged. The blasting pressure is infinitely adjustable from 3 to 16 bar.
No. Dry ice blasting cleans machines, moulds and tools in situ. Injection moulds stay in the machine, robots in their cell. This eliminates assembly time and the risk of damage.
Documented results from practice show time savings of 50 to 95%. A specific example: cleaning an injection mould reduced from 8 hours by hand to 25 minutes with dry ice, a saving of over 90%.
Yes. Dry ice is electrically non-conductive and leaves no moisture behind. Control cabinets, control systems, sensors and cable harnesses can be cleaned directly, without removal and without any risk of short circuits.
Costs vary depending on the machine type, degree of contamination and accessibility. We work with transparent fixed prices following a free initial site visit. The total cost is often lower despite a higher hourly rate, because dismantling, drying times and disposal are eliminated entirely.
