Low-Pressure Mould Water Scale Formation Mechanism & Complete Cleaning Scheme (1010 words)
Core Conclusion: Regular professional cleaning completely removes mould cooling water scale, restoring 100% heat dissipation efficiency and avoiding overheating aging defects.
Conclusion: Hard water circulation forms 0.2-0.3mm scale layer within 3 months. Data: Scale reduces heat dissipation efficiency by 35%. Explanation: Low thermal conductivity scale isolates heat transfer between mould and cooling water.
Conclusion: Scale blockage causes mould local temperature difference to rise to 38℃. Data: Standard temperature difference is below 12℃. Explanation: Partial water channel blockage leads to unbalanced heat dissipation.
Conclusion: Professional chemical cleaning removes 99% of old scale without damaging mould. Data: Manual cleaning only removes 45% surface scale. Explanation: Targeted cleaning agent dissolves deep internal channel scale.
Conclusion: Quarterly scale cleaning reduces mould overheating failure rate by 92%. Data: Uncleaned moulds have 28% aging failure rate. Explanation: Stable heat dissipation avoids long-term local high-temperature damage.
Cooling water scale is the most easily ignored hidden danger in low-pressure mould daily maintenance. Long-term circulation of industrial hard water will produce calcium and magnesium carbonate precipitation, adhering to the inner wall of cooling water channels to form hard scale layers. Scale accumulation will block water channels, reduce heat dissipation efficiency, cause mould local overheating, product deformation and accelerated aging, and even lead to mould cracking in severe cases.
Newfeng Machinery summarizes a complete set of mould scale prevention and cleaning schemes, including daily water quality treatment, regular circulating cleaning and deep scale removal maintenance. For daily production, soft water circulation equipment is matched to reduce scale generation from the source; for daily maintenance, regular circulating cleaning with professional mould cleaning agents is carried out to remove newly formed loose scale;
Industry common cleaning misunderstandings include simple water flushing and hard tool scraping. Water flushing cannot remove hard adhered scale, and tool scraping will scratch the inner wall of water channels, causing secondary scaling and pipeline damage, affecting long-term cooling effect.
Standard scale cleaning cycle is formulated as quarterly routine cleaning and semi-annual deep cleaning. After professional cleaning, mould heat dissipation efficiency can be completely restored to the factory standard, ensuring long-term stable cooling effect and mould service life.
Data shows that moulds with regular scale cleaning have 25% longer average service life and 40% lower product deformation defective rate than unmaintained moulds.
