Industry Background
Components of construction machinery, mining equipment and large cast & forged parts feature large size, heavy weight and complex structures, and are mainly transported by sea. During long ocean voyages lasting weeks or even months, large parts face difficulties in surface treatment and packaging. Rust damage leads to extremely high repair costs or even irreparable losses.
Industry Challenges
1.Rusting of large components during ocean shipping
Oversized parts cannot be packed with standard containers, so traditional anti-rust methods fail to provide full coverage. Salt spray causes rust on machined surfaces, bringing high repair costs after arrival.
2.Long in-process cycle
Large castings and forgings go through multiple processes, workshops and even different factories. The interval period far exceeds the effective protection life of traditional anti-rust oil.
3.Difficult application and removal of anti-rust oil
Manual oil coating for large components and degreasing after arrival are extremely time-consuming and labor-intensive. Large-scale cleaning equipment requires huge investment, and waste liquid output is massive.
4.Failed protection on assembled special-shaped parts
Heavy machinery is assembled with parts of different materials. Moisture easily remains in assembly gaps under humid conditions, becoming hidden rust sources. Traditional oil coating cannot cover inner gaps of assemblies.
VCI Solution Value Proposition
We provide customized large-size VCI packaging solutions for bulky components. Full anti-rust protection is realized without full surface oil coating, greatly simplifying operation procedures.
Recommended Solutions & Product Features
VCI Anti-Rust Film (Large Size / Heat-Shrinkable): Customized oversized film bags according to component dimensions. Heat-shrink packaging forms tight sealing, suitable for large gears, casings and other special-shaped parts.
VCI Anti-Rust Paper / Cloth: Large-size products for covering large flat surfaces and easy layering during stacking.
VCI Anti-Rust Agent: VCI powder or emitters placed in large packaging spaces; vapor molecules diffuse naturally to cover all metal surfaces.
VCI Anti-Rust Liquid (Spray Type): High-flow spray equipment quickly treats surfaces of large components. A dry film forms after drying with no need for subsequent cleaning.
Expected Benefits
Ocean shipping rust rate of large components reduced by over 90%
Large-scale degreasing and cleaning processes eliminated, saving equipment and labor costs
Rust problems inside gaps of assemblies effectively controlled
