Chemicals used in mold maintenance are selected to clean, protect the mold surface, and remove contamination that occurs during production. The correct chemical selection extends mold life and keeps part quality consistent.
Basic chemicals used in mold maintenance
1. Mold Cleaners
- Dissolves plastic, resin, and carbon residues
- Cleans oil and dirt buildup
- Generally fast-evaporating solvent-based
2. Rust removers / corrosion inhibitors
- Cleans light rust and oxide layers on the surface
- Exposes the metal surface without damage
- Used to prepare the mold for production
3. Rust Preventive Oils
- Forms a thin protective film on the mold surface
- Prevents rusting by blocking contact with moisture and oxygen
- Used for long-term storage
4. Release Agents
- Ensures easy removal of plastic parts from the mold
- Available in silicone-based or silicone-free types
- Reduces adhesion and surface damage
5. Carbon removers
- Cleans burnt plastic residues formed at high temperatures
- Effective especially on tough stains
- Requires controlled use
6. Oil and grease cleaners
- Removes hydraulic oil and machine grease residues
- Ensures the mold surface is clean
Points to consider
- Abrasive and aggressive chemicals can damage the surface coating
- Incorrect solvent usage can affect mold tolerance
- Protective application must be done after cleaning
