Dry Film Lubricant Solves New National Standard Issues for Charging Pile Contacts

The 2026 new national standard GB/T 46519-2025 for charging piles has been fully implemented, with stricter CQC and 3C certification audits. Clean contact surfaces and multi-material compatibility are mandatory requirements for market access. China now has over 21.48 million charging facilities. Under frequent high-voltage fast charging plugging and extreme outdoor temperatures, contact failures and certification rejections have become common headaches for manufacturers. A compliant specialized lubricant is the ideal solution.

Three Major Drawbacks of Conventional Greases

1. Sticky assembly and high defective rate The tiny 0.1mm gaps between PC shells, silver-plated contacts and silicone seals lead to severe friction with ordinary greases. They scratch plating and deform plastic parts, pushing production defect rates up to 8% for some manufacturers and incurring high rework costs.

2. Material incompatibility and safety risks Traditional greases corrode silver plating and swell silicone seals over time, raising contact resistance and causing seal failure that lets dust and water in. This fails the multi-material compatibility rules of the new national standard.

3. Oil residue leads to certification failure Slow-evaporating regular greases trap dust on contacts, triggering overheating and short circuits. Surface oil contamination is a clear deduction item in CQC testing, blocking product launch.

Baoxing BX Dry Film Lubricant Compliant Lubrication for Charging Pile Contacts

With 20 years of specialty lubrication experience, Baoxing developed BX-120/A(F-107)-WY dry film lubricant fully aligned with the new national standard:

1. Fast-drying zero-residue for smooth certification Solvent evaporates rapidly after application, forming an ultra-thin dry film that repels dust and eliminates fire hazards from short circuits, meeting CQC surface cleanliness standards.

2. Low friction for smoother assembly and higher yield Custom friction-reducing formula cuts plugging resistance by 40% without damaging silver plating or plastic housings, lowering production waste.

3. Universal material compatibility with no corrosion or swelling Tested compatible with PC plastic, silver-plated copper and silicone O-rings. It causes no plating corrosion or rubber swelling, and performs steadily from -40℃ to 250℃ for outdoor high-voltage charging scenarios.

4. Long-lasting wear-resistant coating with minimal maintenance High-adhesion dry film withstands over 10,000 plugging cycles per third-party testing, matching daily 50 plugging cycles of ultra-fast chargers and slashing after-sales maintenance costs.
