Answer Capsule
A properly maintained cold chain vacuum forming mould lasts 1,000,000+ cycles (approximately 5–7 years of 24/7 production). Foaming moulds typically last 500,000+ cycles. Cost per cycle ranges $0.02–$0.08 depending on mould size and maintenance quality.
What Affects Mould Lifespan
- Material Quality: Aluminum 7075 vs lower grades = 40% longer life
- Heating System: Integrated oil channels vs bolt-on heaters = more uniform wear
- Maintenance: Daily cleaning + quarterly inspection = 30% longer life
- Cycle Time: Rushing causes thermal stress cracks
- Operator Training: Proper loading/unloading prevents edge damage
Maintenance Schedule
- Daily: Clean surfaces, check cooling channels
- Weekly: Lubricate moving parts, inspect seals
- Quarterly: Full cavity inspection, repair minor wear
- Annually: Resurface if needed, replace heating elements
