Maintenance chemicals in plastic injection molding machines are used to ensure that machines and molds operate cleanly, efficiently, and with a long lifespan. These products are preferred for cleaning, lubrication, corrosion prevention, and protective maintenance.
Maintenance Chemicals Used in Plastic Injection Molding Machines
1. Mold Cleaners
- Removes resin, oil, and carbon residues
- Prepares the mold surface for production
- Helps keep vent channels clean
2. Mold Release Agents
- Ensures easy demolding of parts
- Reduces sticking and surface deformation
- Available in silicone and non-silicone types
3. Rust Inhibitors / Protective Oils
- Creates a protective film on the mold surface
- Provides protection against moisture and oxidation
- Used for long-term storage
4. Purge (Screw Cleaning) Compounds
- Cleans old raw materials remaining in the screw and barrel
- Used during color and material changes
- Reduces carbonized plastic residues
5. Oil and Grease Cleaners
- Dissolves hydraulic oil and machine dirt
- Ensures equipment cleaning during maintenance
6. Silicone Sprays and Maintenance Sprays
- Protects moving parts
- Used for maintenance of rubber and plastic parts
- Provides light lubrication and water repellency
7. Cooling System Cleaners
- Removes scale and sediment buildup
- Ensures efficient operation of water channels
Points to Consider
- Chemical selection should be compatible with mold material
- Abrasive solvents should be avoided
- PPE must be used for operator safety
- Should be applied according to a regular maintenance plan
