Introduction
A high-quality plastic injection mould is a significant investment for any manufacturer. One poorly maintained tool can lead to costly downtime, defective parts, and repeated repairs—wiping out potential returns. Proper mould maintenance is the most critical factor in protecting this investment and ensuring your tooling delivers reliable performance for years to come.
This guide, Mould Maintenance 101, outlines practical steps, checklists, and best practices to help you extend your mould’s life, maintain part quality, and prevent costly disruptions in production.
Daily and Weekly Maintenance Checklist
Regular upkeep ensures your mould stays in top condition. Here’s a practical daily and weekly maintenance routine:
1. Routine Cleaning
Remove plastic residue, burnt material, or gases after each production run.
Use suitable cleaning solvents that do not corrode steel surfaces.
Pay special attention to cavities, vents, and runner systems to prevent material buildup.
2. Lubrication
Apply high-temperature grease to guide pins, ejector pins, slides, and other moving components.
Proper lubrication reduces friction, wear, and the risk of component seizure.
Check lubrication frequency according to production hours and mould complexity.
3. Visual Inspection
Look for early signs of wear, flash, or corrosion.
Inspect cavity surfaces, parting lines, and ejector pins.
Catching minor issues early prevents major repairs and production delays.
Preventative and Long-Term Care
Beyond daily checks, certain tasks protect your mould over the long term:
1. Mould Storage
When a mould is not in use, store it in a clean, sealed environment.
Apply rust-preventative oil or protective coatings to prevent corrosion.
Proper storage maintains the mould’s surface finish and mechanical integrity.
2. Ejector System Check
Inspect and calibrate the ejector system periodically.
Ensure smooth part ejection to avoid damage to both the mould and produced parts.
3. Water Line Cleaning
Clean cooling water lines to prevent scale buildup, which can reduce heat transfer efficiency.
Efficient cooling maintains cycle times and consistent part quality.
The Value of Professional Service
While in-house maintenance keeps your mould running daily, periodic professional servicing is essential for optimal performance.
Our Bhoomi Mould Lifetime Service ensures your mould is fully inspected, refurbished, and restored to peak condition. Expert technicians identify hidden issues, adjust tolerances, and optimize all components—extending your tool’s life and safeguarding your production.
Conclusion and Call-to-Action
Mould maintenance is an investment, not an expense. Regular cleaning, lubrication, inspection, and professional servicing protect your tooling, ensure consistent part quality, and reduce costly downtime.
