At JBRplas, we recognize that mold maintenance is the backbone of stable production.A meticulously maintained mold not only ensures consistent part quality but also minimizes unexpected downtime and maximizes tooling longevity. Based on years of industry experience, we've systematized our maintenance approach—a standard we rigorously follow and are pleased to share.
🎯 Purpose of Maintenance Standards
This protocol is designed to:
- Ensure stable mold operation
- Prevent production failures and quality defects
- Extend the service life of injection molds
- Optimize the cost-to-value ratio of tooling investment
⚙️ Scope
These standards apply to mass-production molds for machines ranging from 55T to 470T. Exclusions include trial molds and prototype tooling.
🔧 Classification of Maintenance Operations
🛠️ Daily Maintenance
Frequency: Every 12 hours (per shift shift)
Responsible Personnel: Process Technician
Critical Tasks:
- Clean parting lines, cavity surfaces, and ejector systems to remove contaminants
- Inspect springs, pins, and sliders for signs of scoring or malfunction
- Verify hydraulic systems and mold heater functionality
- Check cooling channels for blockages and ensure optimal temperature control
- Apply lubrication to guide pins, sliders, and all moving assemblies
- 🗓️ Periodic Maintenance (Based on Shot Count)
- Machine Tonnage/ Maintenance Interval
- 55T – 150T/Every 100,000 shots
- 150T – 470T/Every 50,000 shots |
Key Actions:
- Execute all daily maintenance procedures
- Disassemble key components (ejector pins, sliders) for wear assessment
- Clean and restore venting systems to prevent gas traps
- Repair damaged surfaces through welding or polishing
- All activities must be documented in maintenance logs for traceability
✨ Appearance Maintenance
- Pre-Production: Full cleaning of cavity surfaces and ejector paths
- Post-Production:complete daily maintenance protocols，apply anti-rust oil - Proper storage in fully closed position with visible labeling.
⚠️ Critical Maintenance Precautions
- Never Allow Dry Running: Lubricate all moving components promptly.
- Zero-Tolerance for Contaminants: Halt production if parts stick or surface debris is detected.
- Immediate Response Protocol: Sounds indicating abnormal ejection or movement require instant shutdown and inspection.
💼 Why This Matters—and How JBRplas Adds Value
Our disciplined adherence to these standards has enabled clients to achieve:
- Tool Life Improvements by 20-40% due to preventive care
- Production Efficiency Increases from reduced unplanned downtime
Consistent Part Design for Manufacturability (DFM) consultation to high-volume production support, we embed this precision philosophy into every project phase. Our dedication transforms maintenance from a "cost center" into a strategic enabler of reliability.
