Solvent selection for mold cleaning is made to effectively dissolve resin, oil, carbon, and dirt residues without damaging the mold surface. Incorrect solvent selection can degrade the surface coating, accelerate corrosion, or damage mold dimensions.
Solvent selection for mold cleaning
1. Solvent selection based on dirt type
-
Plastic and resin residues:
- Ketone-based solvents (e.g., acetone derivatives)
- Special mold cleaners
-
Oil and grease residues:
- Hydrocarbon-based degreasers
-
Carbonized burn residues:
- Strong industrial carbon removers
2. Selection based on mold surface
-
Polished surfaces:
- Low-aggressive, surface-friendly solvents
-
Coated molds (nitride, chrome, etc.):
- Neutral pH and non-abrasive products
-
Aluminum molds:
- Low corrosion risk solvents
3. Evaporation rate
-
Fast-evaporating solvents:
- Fast cleaning and return to production
-
Slow-evaporating solvents:
- Longer action time for tough dirt
4. Safety and compatibility
- Low VOC (volatile organic compound) preferred
- Good ventilation required for flammable solvents
- Operator safety (gloves, goggles) is mandatory
5. What to avoid
- Corrosive acids (damage surface coating)
- Cheap, uncontrolled industrial solvents
- Strong alkaline solutions that corrode the mold while dissolving plastic residues
