Key Maintenance Practices
Mold Inspection & Analysis
Before each production cycle, inspect mold cavities, surfaces, and cores for wear or contamination. Monitor ejector pins, cooling channels, and part quality for potential issues.
Cleaning & Debris Removal
After production, clean mold surfaces using solvents, brushes, or dry ice. Remove all plastic residues, dust, and moisture from cavities and cooling channels to prevent corrosion and defects.
Lubrication of Moving Parts
Lubricate ejector pins, slides, and other moving components to ensure smooth operation and prevent sticking. Use mold-safe lubricants that do not affect plastic parts.
Fasteners and Hardware Check
Verify all bolts, screws, and connectors are secure. Inspect cooling hoses and channels for leaks. Ensure alignment and torque specifications are maintained to prevent mold damage.
Surface Protection
After cleaning and drying, apply anti-rust coating to all mold surfaces. Proper protection prevents corrosion, maintains surface quality, and extends mold lifespan.
Record & Plan Maintenance
Document all maintenance actions, repairs, and anomalies. Use records to plan preventive maintenance schedules and track mold performance over time.
