Mold Storage Guidelines
Injection molds are high-precision, high-investment assets that require careful storage to ensure production stability and cost control. If the storage environment is mismanaged, corrosion, deformation, and even total mold failure may occur. Structuring a proper mold storage system supports fast allocation and scheduled inspections.
In modern manufacturing systems, digital mold management has become a rising trend. By using traceable systems and barcode tracking, the risk of mold loss or confusion can be significantly reduced. This approach also enhances human efficiency and extends mold service life ROI.
How to scientifically manage mold storage conditions?
Mold storage is not simple placement—it requires systematic protection against corrosion, rust, and impact. Improper stacking or lack of positioning design can lead to deformation or stuck slides. A complete storage plan should incorporate humidity control, ground flatness, and unique mold identification.
- Anti-Rust Measures: Apply rust prevention oil and seal the mold in protective bags
- Positioning Design: Racks should include stoppers to prevent mold movement
- Climate-Controlled Storage: Temperature and humidity control systems prevent rust
- Mold Tracking System: Each mold should have a unique ID with corresponding digital records
Proper storage ensures that molds are always ready for production
How should mold maintenance cycles be determined?
Maintenance schedules vary depending on mold usage frequency, material type, and cavity complexity. Over-maintaining or neglecting maintenance leads to additional risks and wasted costs. Companies should implement a usage-based dynamic maintenance plan for precision care.
- Cycle-Based Maintenance: Perform Type A maintenance every 50,000 shots
- Usage Monitoring Feedback: Use injection machine counters or sensors to auto-trigger alerts
- Digital Maintenance Logs: Log all maintenance details using apps or spreadsheets
- Technical Training System: Frontline technicians must be certified and regularly retrained
A scientific maintenance rhythm is key to extending mold life
What are the key indicators for scrapping a mold?
Molds are consumable assets with limited service life; once precision, structure, or materials degrade, disposal is essential. Persisting with worn molds introduces safety hazards and defective output. Metrics like total shots, repair frequency, and defect rates help define when to retire a mold.
- Precision Degradation Threshold: When cavity wear exceeds design tolerances
- Repair Cost Exceeds Value: One repair exceeds 50% of new mold cost
- Frequent Failures: Repeated ejection pin breaks or flash issues in a short time
- Structural Damage: Base deformation or irreversible gate damage
Timely mold retirement protects production consistency and safety

How to maximize mold value across its lifecycle?
Mold management goes beyond storing, maintaining, and scrapping—it determines production agility and efficiency. Companies that digitize and visualize mold status gain strategic advantages in lead time and allocation. Integrating mold tracking with ERP/MES enables real-time and precise decision-making.
1.Smart Tracking System: Use barcodes and IoT for mold location monitoring
2.Lifecycle Budgeting: Plan depreciation and ROI from the design phase
3.Mold Sharing Program: Reallocate molds internally to maximize use
4.Predictive Maintenance: AI analysis predicts wear for early intervention
Conclusion
Mold storage, maintenance, and retirement are not just technical routines—they’re key levers in long-term profitability for injection molding businesses. Executing detailed procedures within a systematic framework is the heart of mold asset management. Treating every mold as a valuable asset turns cost centers into value generators. With digitalized tracking and preventive alerts, companies gain resilience in volatile markets.
