Solution chosen by a global beverage manufacturer
Effective removal of rust and scale from injection molds
Initial situation
A leading multinational beverage manufacturer encountered challenges with their injection molding machines used for producing molds. The external surfaces of the machines and their internal cooling lines were affected by corrosion and limescale build-up. These issues led to several complications:
- Rust on external surfaces negatively affected cleanliness and posed potential food safety risks.
- Accumulated scale and corrosion compromised mold quality, resulting in production faults and losses.
- The internal cooling systems became clogged and inefficient, requiring labor-intensive mechanical cleaning using abrasive tools.
Initially, hydrochloric acid-based cleaners were employed to address these issues. Although effective under controlled conditions, these substances did not meet NSF food-safety standards, aggressively attacked aluminum components, and required extensive use of personal protective equipment (PPE).
Solution
The company switched to Interflon Clean Special, a highly effective cleaning agent based on phosphoric acid. Unlike previous cleaners, Interflon Clean Special is non-aggressive, NSF A3 certified, and safe for use in food-production environments. It efficiently removes rust and limescale without damaging aluminum surfaces, provided the cleaned areas are rinsed thoroughly after application to remove any acidic residues.
Benefits
- Fast and effective removal of rust and limescale
- Non-aggressive formula, safe for aluminum and other sensitive materials when rinsed properly
- NSF A3 certified, ensuring compliance with food-safety standards
- Reduced need for protective equipment, enhancing operator safety and convenience
- Economical in use
- Compliant with the European Detergent Regulation and readily biodegradable
Conclusion
Interflon Clean Special offered a safer, more effective and food-safe alternative, suitable for use in beverage production environments. The beverage manufacturer significantly improved equipment reliability, mold quality, and compliance with stringent food-safety requirements, ultimately reducing downtime and maintenance costs.
