Precision Joint-Free 0.20mm Tinplate Strip for Lever Arch File Mechanisms
URL Slug: precision-joint-free-tinplate-strip-lever-arch
Product Summary
This precision narrow tinplate strip is engineered specifically for lever arch file mechanisms. With a thickness of 0.20mm and width options of 6.5mm or 7.0mm, it maintains a precision width tolerance of ±0.03mm. The strip is 100% joint-free, camber-free, and burr-free, ensuring smooth feeding in high-speed stamping processes. The equal tin coating (4.2/4.2 to 5.6/5.6 g/m²) provides consistent corrosion resistance. Post-slitting edge passivation and anti-rust oiling make it ideal for high-heat, high-humidity climates.
Key Features
-
Gauge Consistency ≥99% – Uniform 0.20mm thickness reduces stamping defects and tool wear, improving production yield.
-
±0.03mm Width Tolerance – Ultra-strict control ensures precise fit in die cavities, minimizing jams and misalignment.
-
100% Joint-Free Coil – Eliminates weld joints that cause breakage, enabling uninterrupted high-speed production lines.
-
Burr-Free & Camber-Free Edges – Clean slitting edge prevents scratching of dies and ensures consistent strip alignment.
-
Anti-Rust Edge Treatment – Post-slitting passivation and oiling protect the strip during storage and shipping, even in humid climates.
