Industry Background
Automotive powertrain, transmission and chassis components are exposed to high humidity and high salinity environments during global procurement and transoceanic shipping. Meanwhile, vehicle manufacturers have imposed increasingly strict requirements for parts to be used directly on production lines. Traditional anti-rust oil is widely criticized for heavy cleaning workloads and severe environmental issues.
Industry Challenges
1.Frequent rusting during export shipping
High salt spray and humidity inside ocean containers cause visible rust spots on metal parts within weeks of transportation, leading to port rejection, return shipments and compensation claims.
2.Burdens brought by residual anti-rust oil
Traditional oil-based rust preventatives require degreasing and cleaning before assembly, which increases investment in cleaning lines and labor costs. Oil contaminants tend to absorb workshop dust and degrade the quality of subsequent welding and gluing processes.
3.Corrosion caused by container condensation
The diurnal temperature difference aboard ocean-going vessels can exceed 20°C. Condensed water dripping from container inner walls triggers localized electrochemical corrosion on parts, especially in thread holes, gaps and other blind areas.
4.Environmental compliance risks
Anti-rust oils containing nitrites and heavy metals fail to comply with export environmental standards such as RoHS and REACH, resulting in risks of full-container returns and failed supply chain audits.
VCI Solution Value Proposition
We provide an oil-free full-process anti-rust solution covering delivery to assembly lines. It eliminates degreasing procedures, speeds up production flow and fully meets global environmental compliance requirements.
