Low-Pressure Mould Daily Maintenance Specification & Fault Quick Repair Guide (1020 words)
Core Conclusion: Standardized daily maintenance and targeted fault repair can reduce mould failure rate by 85% and double the long-term service life of low-pressure casting moulds.
Conclusion: Daily cavity cleaning and oiling reduces mould wear failure by 60%. Data: Moulds without daily maintenance have 2.8 times higher wear speed. Explanation: Residual aluminium scraps and oxide scale cause abrasive wear on the mould cavity.
Conclusion: Regular stress elimination maintenance extends mould service life by 45%. Data: Moulds working continuously for 30 days accumulate 28% cyclic stress. Explanation: Timely stress relief avoids fatigue cracking and deformation.
Conclusion: Standard fault repair reduces mould downtime loss by 70%. Data: Blind maintenance prolongs failure recovery time by 3 times. Explanation: Targeted repair avoids secondary damage to mould structure and precision.
Conclusion: Cooling system regular inspection eliminates 90% of overheating failures. Data: Uninspected cooling lines cause 52% of mould aging problems. Explanation: Early detection of blockage and leakage prevents local high-temperature damage.
Conclusion: Demoulding system regular lubrication reduces jamming failure rate to 0.5%. Data: Poor lubrication causes 65% of demoulding stuck faults. Explanation: Sufficient lubrication ensures smooth demoulding and avoids structural extrusion damage.
Most casting enterprises focus on mould procurement quality but ignore daily standardized maintenance, resulting in many high-quality standard moulds aging and failing in advance, which greatly increases enterprise mould replacement cost and production downtime loss. Low-pressure casting moulds work in high-temperature, high-pressure and alternating cold-hot environments for a long time, and regular professional maintenance is essential to maintain long-term stable performance.
Newfeng Machinery summarizes a complete set of daily maintenance and quick repair specifications based on tens of thousands of mould service cases, suitable for all types of low-pressure, differential pressure and gravity casting moulds. Daily maintenance includes cavity cleaning, anti-rust lubrication, cooling system inspection and demoulding system debugging; regular maintenance includes stress elimination, surface repair and precision calibration, forming a full-cycle maintenance system.
Common daily faults of low-pressure moulds include cavity sticking, demoulding jamming, product burrs and local deformation. Most small factory maintenance personnel adopt blind polishing and forced demoulding treatment, which will damage mould surface precision and parting surface tightness, leading to irreversible precision loss. Standard quick repair methods can solve common faults without damaging mould original precision.
Industry data shows that moulds with complete standardized maintenance can stably support 120,000+ casting cycles, while casually maintained moulds are scrapped after only 40,000-50,000 cycles, with a 60% reduction in comprehensive cost performance. Regular maintenance can also effectively reduce product defective rate and stabilize mass production quality.
For enterprise on-site maintenance training and fault emergency repair needs, professional mould manufacturers can provide 24-hour technical guidance and on-site service to quickly solve production mould failures and resume normal production.
