Uses of dry ice cleaning machines

Applications of Dry-Ice Cleaning: Industrial Molds Tire molds, rubber molds, polyurethane molds, polyethylene molds, PET molds, foam molds, injection molds, alloy die-casting molds, hot core boxes and cold core boxes used in casting—can remove residual resin, failed release coatings, carbonized films, oil stains, and clear blocked vent holes. After cleaning, molds appear bright and like new. Online cleaning eliminates the need to cool down or disassemble molds, thus avoiding the corrosion and damage caused by chemical cleaning methods, mechanical damage and scratches from mechanical cleaning methods, and precision degradation resulting from repeated assembly and disassembly. Most importantly, it removes the two most time-consuming steps—mold disassembly and waiting for the mold to cool down—thereby reducing downtime by approximately 80% to 95%. Petrochemical Industry Cleaning of main blowers, air compressors, smoke extractors, steam turbines, fans, and various types of heating furnaces and reactors to remove coke and carbon deposits. Cleaning polyvinyl chloride resin from heat exchangers; removing oil stains, rust, hydrocarbons, and surface contaminants from compressors, storage tanks, boilers, and other pressure vessels; cleaning reaction kettles and condensers; decontaminating complex machinery; and descaling furnace tubes. Food and Pharmaceutical Industries Successfully removes baked residues, gel-like substances, oil stains, and mixtures of raw materials before baking from ovens. Effectively cleans ovens, mixing and stirring equipment, conveyor belts, molded products, packaging equipment, oven racks, oven trays, containers, rollers, inner walls of freezers, biscuit oven bars, and more. Benefits of dry-ice cleaning: eliminates the use of harmful chemicals, avoids contact between production equipment and hazardous substances, and prevents secondary waste generation; inhibits or removes bacteria such as Salmonella and Listeria, providing more thorough disinfection and cleanliness; avoids damage to electronic equipment that can occur with water-jet cleaning; minimizes equipment disassembly; reduces downtime. Printing Industry Removing ink is often difficult, and accumulated ink on gears and guide rails can lead to poor print quality. Dry-ice cleaning effectively removes all kinds of oil-based and water-based inks and varnishes, cleaning oil stains, ink buildup, and dyes from gears, guide rails, and nozzles, while avoiding the discharge of hazardous waste and solutions and preventing personnel injuries caused by dangerous solvents. Power Industry: Can clean power boilers, condensers, and various heat exchangers; can directly clean live transformers (below 37KV), insulators, switchgear cabinets, wires, and cables under load; cleans generators, motors, rotors, stators, and other components without damaging them; removes rust, hydrocarbons, and sticky powders from turbine blades and impellers without having to disassemble the blades, saving time and effort required for re-balancing. Automotive Industry Cleaning door panels, roofs, interiors, underbodies, and other areas without leaving water marks or causing water pollution; cleaning carburetors and removing paint from car surfaces; removing engine carbon deposits. Chemical treatments for carbon deposits typically take at least 48 hours and involve toxic substances. Dry-ice cleaning can completely solve carbon-deposit problems within 10 minutes, saving time and reducing costs, with a 100% removal rate. Electronics Industry Cleaning internal grease and dirt from robots and automated equipment; removing solder paste, contaminated coatings, resins, solvent-based coatings, protective layers, and photoresist from printed circuit boards. Aerospace Industry Pre-treatment processes for missile and aircraft painting and final assembly; removing paint from composite molds and special aircraft components; cleaning engine carbon deposits; maintenance cleaning (especially landing gear and wheel well areas); removing paint from aircraft exteriors; cleaning jet engine conversion systems. Can be performed directly on the aircraft structure, saving time. Shipbuilding Industry Cleaning ship hulls, seawater intake valves, seawater condensers and heat exchangers, engine rooms, mechanical and electrical equipment—cleaner than conventional high-pressure water jet cleaning. Nuclear Industry If traditional cleaning methods such as water, sandblasting, or chemical agents are used to clean nuclear equipment, these media themselves become contaminated with radioactive elements. Handling these secondarily contaminated media requires both time and financial resources. In contrast, dry-ice cleaning uses dry-ice particles that are directly sprayed onto the object being cleaned, sublimating instantly, thus eliminating the risk of secondary contamination. The only waste requiring disposal is the nuclear-contaminated debris removed during cleaning. General Manufacturing Industry Cleaning oil stains, paints, inks, adhesives, carbon deposits, asphalt, surface rust, industrial fans, welding slag, electroplating coatings, and more.
