Armor Cases Built on Energy Management, Not Bulk

Adding thickness is not protection. A case protects by deforming on impact and spreading the energy away from the phone body. That is why our armor ranges use two materials with different jobs rather than one thick shell.

How the energy is handled

LayerJobMaterial behaviour
Outer shellKeeps shape, holds the phone rigidPC — resists bending, but cracks rather than absorbs if used alone
Inner sleeveAbsorbs impactTPU — deforms and rebounds, spreading energy
Corner cushionsTakes the first contactAir pockets compress on corner drops, where most damage happens
Camera and screen lipsKeeps glass off flat surfaces1.5 mm above the lens, 0.8–1.0 mm above the screen

Why corners matter more than the back

Drop a phone and it almost never lands flat on its back — it lands on a corner, and the corner is where the glass and the frame meet. Corner reinforcement is worth more than back-panel thickness, which is why every armor range here carries extra material at the corners and keeps it off the closing face.

The foldable constraint

On a foldable you cannot reinforce freely: added material on the closing face stops the phone folding flat. All reinforcement is therefore placed on the outer faces and the spine side.

Frequently asked

Is PC or TPU better for drop protection?

TPU absorbs more energy and protects better in a single drop; PC keeps its shape over time. That is why hybrids exist.

What drop height are the armor ranges tested to?

We test to roughly 1.2 m onto a hard flat surface, corner-first. Ask any supplier for the height and the surface — a number without those two details means nothing.

Does armor thickness stop a foldable closing?

Not on our construction. Reinforcement is kept off the closing face, which is the main design constraint.

Can you print a logo on a rugged case?

Yes — UV print or silk screen on the back panel, laser engraving on metal accents.
