Precision Where It Matters Most
There’s a moment in precision manufacturing when a component either fits perfectly or brings an entire production line to a halt. We’ve seen it countless times – that’s why we obsess over tight-tolerance slitting for our stainless steel narrow coils. Unlike standard coils that get the job done, ours are engineered for applications where 0.1mm can make or break a project.
Take automotive sensor brackets for example. One of our European clients switched to our 316-grade narrow coils (0.3mm × 45mm) after facing 12% rejection rates with their previous supplier. The difference? Our ±0.05mm width tolerance and edge condition that eliminates post-slitting burr removal.
Beyond the Spec Sheet
- Material selection isn’t just about grades – we work with 301 for elasticity in spring contacts, 430 for cost-effective decorative trims, and custom 304L for medical components requiring superior weldability
- Our slitting lines maintain surface integrity even at 600m/min speeds, critical for electronics manufacturers who can’t afford microscopic edge defects
- Thickness consistency is ±1.5% of nominal – a detail that matters when you’re stamping 0.08mm-thin shims for smartphone components
- Hardness options go beyond standard 1/4H-3/4H; we’ve developed custom tempers for clients needing specific spring-back characteristics
The real test comes in applications like deep-drawn medical trays. One customer reported a 40% reduction in die wear after switching to our annealed 304 coils with optimized grain structure. That’s the kind of feedback that validates our approach to precision.
Why We Stand Out
Being based in China’s steel hub gives us direct access to premium raw materials and proprietary annealing processes. But what really differentiates us is our willingness to customize – not just dimensions, but properties. Need 316L with controlled magnetic permeability for MRI components? Or 430 with enhanced ductility for architectural trims? We’ve done both.
Our quality system follows ASTM A480 for dimensional tolerances and EN 10088 for metallurgical requirements, with full traceability from melt to slit. Each coil comes with actual test data, not just certificate of compliance.
When you contact us, you’ll talk to engineers, not sales reps. We ask about your forming processes, tooling conditions, and end-use environments – because the best solution depends on understanding your full production context. Let’s discuss how we can optimize your material supply, whether you need 500kg or 50 tons.
