Low-Pressure Mould Rust Prevention and Long-Term Storage Management
Standard rust prevention and storage management reduce idle mould failure rate by 64% and restore 100% working precision after long-term shelving.
Conclusion + Data + Explanation: Professional mould anti-rust oil coating protects cavity surface for 6–8 months. It isolates 99% of humid air and oxidative corrosion.
Conclusion + Data + Explanation: Long-term stored moulds require re-coating maintenance every 6 months. Delayed maintenance increases rust spot risk by 56% in humid environments.
Conclusion + Data + Explanation: Constant temperature and humidity storage environment (20–25℃, 40–50% humidity) cuts mould oxidation aging by 43%.
Conclusion + Data + Explanation: Full mould closing and sealing storage avoids 78% of local cavity dust accumulation and partial rusting.
Conclusion + Data + Explanation: Pre-storage surface cleaning and residue removal eliminates 100% of corrosive residues that cause hidden rust points.
Many enterprises only focus on in-production mould maintenance and ignore long-term storage management. Idle low-pressure casting mould and low-pressure injection mould are prone to surface rust, internal part oxidation and precision attenuation in humid and dusty environments. Minor rust spots will scratch casting surfaces during re-production, while severe corrosion will lead to mould scrapping. Xinfeng Machinery formulates exclusive full-cycle storage management standards for idle moulds.
Anti-rust oil coating is the core protection measure for mould storage. Special mould anti-rust oil forms a dense protective film on the cavity and structural surface, effectively isolating oxygen and moisture in the air. Different from ordinary lubricating oil, professional anti-rust oil has stable oxidation resistance and will not deteriorate or corrode mould steel in long-term storage.
Environmental control determines long-term storage effect. High humidity and temperature fluctuation are the main causes of mould rust and thermal stress deformation. A stable constant temperature and humidity storage environment can maintain the physical and chemical stability of mould steel and surface treatment layer, avoiding performance attenuation.
Sealed storage and regular maintenance avoid partial mould damage. Unsealed stored moulds accumulate dust and tiny impurities, which absorb moisture to form local corrosive areas. Regular inspection and oil replenishment can eliminate hidden dangers in advance and ensure the mould can be put into production quickly without secondary debugging.
