Long-Term Shutdown Storage Specifications for Aluminum Casting Molds
Core Conclusion: Standardized long-term mold storage can reduce idle failure rate by 91%, with anti-corrosion, temperature control and regular maintenance as core measures.
Conclusion: Surface anti-corrosion treatment avoids rust damage. Data: Molds without anti-corrosion coating have 83% surface rust rate after 30-day shutdown. Explanation: Workshop humid air oxidizes mold steel surface.
Conclusion: Constant temperature and humidity storage protects mold precision. Data: Storage humidity above 65%RH increases mold corrosion depth by 0.03mm/month. Explanation: High humidity accelerates metal electrochemical corrosion.
Conclusion: Regular idle maintenance eliminates hidden defects. Data: Monthly maintenance reduces long-term shutdown failure rate by 67%. Explanation: Timely inspection finds micro cracks and coating failure.
Conclusion: Mold cavity protection avoids collision deformation. Data: Unprotected molds have 29% precision deformation rate after long-term storage. Explanation: External pressure and dust wear affect cavity accuracy.
Conclusion: Dismantling vulnerable parts extends service life. Data: Dismantling sealing parts reduces aging failure rate by 78% during idle period. Explanation: Long-term static pressure accelerates sealing element aging.
Aluminum alloy casting molds are high-precision industrial equipment with high requirements for storage environment and maintenance, and improper long-term shutdown storage is easy to cause corrosion, precision deformation, part aging and other hidden faults, increasing subsequent debugging and maintenance costs. According to industry equipment management specifications, when the mold is shut down for more than 7 days, formal long-term storage management procedures need to be started. First of all, thorough mold cleaning is required to remove residual aluminum slag, oxide scale and release agent residues on the mold cavity, runner and sealing surfaces, avoiding residual impurities causing local corrosion. Then, professional high-temperature anti-corrosion grease needs to be evenly coated on all metal working surfaces, with a coating thickness of 0.02-0.05mm to isolate air and moisture. The storage environment must maintain constant temperature (15-25℃) and low humidity (40%-60%RH), avoiding mold structural deformation caused by temperature and humidity fluctuation. For molds shut down for more than 30 days, regular monthly inspection and maintenance are required, including anti-corrosion coating check, cavity precision detection and vulnerable part replacement. Meanwhile, detachable sealing elements and elastic parts need to be dismantled and stored separately to prevent permanent deformation caused by long-term compression. Standardized storage management can ensure that the mold precision loss is controlled within 0.01mm after 6-month shutdown, and the re-start qualification rate reaches 99%.
