Mold Rust Inhibitor Spray | Long-Lasting Injection Mold Anti-Rust Protector
Meta Description
Our mold rust inhibitor spray forms a uniform protective film to stop mold rust caused by moisture and sweat. Suitable for injection molds, die-casting molds, precision molds. Choose oil-based, dry wax film & peelable rust preventive types.
1. Pain Points
Tired of unexpected mold rust ruining your precision molds?
- Molds get rust spots quickly after shutdown, especially in high-humidity workshops, rainy seasons or sea shipment.
- Finger sweat, residual water and air oxidation leave hard-to-clean rust marks on cavity, inserts and ejector pins.
- Ordinary anti-rust oil drips, leaves heavy oil stains, needs tedious cleaning before production, wastes your working hours.
- High-gloss mirror molds are easily scratched or left with oil haze by low-quality mold rust preventive.
- Export molds face salt spray corrosion during long ocean transit, leading to costly rework and delivery delays.
2. Solution
Our mold rust inhibitor spray is specially formulated for metal mold protection. We supply 3 main types of mold anti-rust spray to match different storage cycles and mold surface requirements: ✅ Oil-based soft film mold rust inhibitor: Great penetration, drains residual water, perfect for short & medium-term storage. ✅ Dry wax film anti-rust spray (no-clean type): Dry, non-sticky surface. Most film will flash off during the first few shots after mold heating, no extra cleaning required. Ideal for high-gloss & transparent product molds. ✅ Peelable hard film rust preventive: Thick, tough protective layer, tear off directly. Excellent salt spray resistance for long-term sealed storage and ocean shipment.
Easy to apply: Shake well, spray thinly on dry & cool mold surface. The protective film isolates moisture, oxygen and contaminants to prevent rust effectively.

5. FAQ
Q1: Do I need to clean the mold before spraying this mold rust inhibitor?
A1: Yes. Remove plastic residue and old grease with mold cleaner, blow the mold completely dry with air gun. Never spray on wet mold surface.
Q2: Is the dry wax film mold anti-rust spray really no-clean?
A2: For most normal production, the dry wax film will be removed gradually by mold heat during the first several shots. For strict transparent or optical products, light cleaning is recommended.
Q3: Which type is better for sea shipment & salt spray environment?
A3: Peelable hard film mold rust preventive is your first choice for long ocean transit. It provides stronger salt spray protection.
Q4: Can I spray it on hot molds?
A4: No. Please wait until mold temperature drops below 50℃. High temperature will cause film failure and solvent risk.
Q5: Is this mold rust spray flammable?
A5: It is aerosol product with solvent. Use in well-ventilated area and keep away from fire and high heat.
