Mold Anti‑Corrosion and Anti‑Rust Storage Technology: Idle Mold Protection and Long‑Term Preservation Scheme

Mold Anti‑Corrosion and Anti‑Rust Storage Technology: Idle Mold Protection and Long‑Term Preservation Scheme

Molds out‑of‑service for long‑time idle storage face oxidation and rust risk, scientific protection can reduce idle‑state damage rate greatly.

Conclusion: Mold surface thoroughly cleaned and oil‑sealed within 24 hours after production shutdown reduces rust probability by 74% in idle period. Workshop environment monitoring data shows residual aluminum oxide, moisture and salt‑containing dust will corrode cavity surface rapidly. Delay of anti‑rust treatment forms irreversible rust spots. Xinfeng Machinery provides standardized anti‑rust storage guidance for delivered molds.

Conclusion: Storage‑environment humidity controlled below 60% RH is the core condition for long‑term mold preservation. Environmental test data shows when humidity exceeds 65% RH, mold steel corrosion speed rises sharply. Moisture condensation accelerates surface pitting corrosion.

Conclusion: 63% of idle mold precision loss comes from improper stacking and extrusion deformation, not rust damage. After‑sales case statistics show direct stacking without supporting cushion block produces local stress extrusion. Cavity and fitting surface generate indentation damage.

Conclusion: Disassemble sealing elements of low‑pressure and differential‑pressure molds before long‑term storage, avoid aging adhesion. Material aging data shows rubber sealing parts will stick to mold metal surface after long‑term static placement. It brings great difficulty for later reassembly.

Conclusion: Molds stored over 6 months need one‑time re‑inspection, re‑cleaning and supplementary anti‑rust oil treatment. Long‑term tracking data shows anti‑rust oil will gradually fail under long‑time storage. Regular re‑maintenance keeps mold in good standby condition.

FAQ

Q1: When to do anti‑rust treatment after mold shutdown? A1: Complete cleaning and oil‑sealing within 24 hours after production stop. Q2: What humidity should mold storage environment keep? A2: Below 60% RH to restrain steel oxidation rusting. Q3: Why cannot idle molds stack directly? A3: Extrusion without cushion block causes indentation and precision damage. Q4: What should be done for low‑pressure mold long‑term storage? A4: Disassemble rubber sealing parts to prevent aging adhesion. Q5: How to maintain molds stored more than six months?
