CNC Machining Craftsmanship

Each frame is CNC-engraved with micron-level accuracy, ensuring tight tolerance and seamless joint lines.
The process takes 2× longer than ordinary casting, but it delivers 10× the structural precision.

Cold Metal. Warm Confidence.

The brushed finish feels soft yet secure — never slippery, never sticky.
Each edge is hand-polished and anodized to maintain color under 200+ hours of UV exposure testing.

Military-Grade Impact Resistance.

The Star Armor case disperses impact energy across the frame — proven to withstand 1.5 m drop tests on all four corners.

Precision Holes. Zero Interference.

Every port and antenna cutout is CNC-drilled — maintaining full 5G, Wi-Fi, and MagSafe performance.

One Frame, Full Coverage.

A separate metal lens guard locks in seamlessly with the frame, protecting every corner from scratches and impacts — without affecting camera clarity.

Alloy Frame × Shock Foam × Hardware Lens Ring.

Unlike ordinary metal bumpers, Star Armor combines multi-part engineering — alloy shell, independent metal buttons, and internal shock-absorbing foam — all precision assembled.
