Non-Stick & Hard Anodized

Aluminum Cookware Inspection

From pressure cookers to frying pans. We verify coating adhesion, bottom flatness, and handle safety to prevent returns and lawsuits.

The Non-Stick (PTFE) Audit

The biggest failure point in aluminum cookware is the coating. If the factory doesn't sandblast the surface correctly before spraying, the coating will peel off after a few washes.

Critical Field Tests We Perform:

Cross-Hatch Adhesion Test We cut a grid pattern into the coating and apply 3M tape. When ripped off, 0% of the coating should detach.

MEK Rub Test Rubbing the surface with Methyl Ethyl Ketone to ensure the coating is properly cured and baked.

DFT Measurement Using digital gauges to measure Dry Film Thickness. Too thin = short life. Too thick = chipping.

Structural Integrity Checks

Concavity Check

Aluminum expands when heated. The bottom must be slightly concave (inwards) so it flattens when hot. If it's convex (outwards), it will spin on the stove ("Spinner" defect).

Tool: Feeler Gauge

Handle Torque Test

Handles on pans loosen over time. We apply specific torque force to screws and pull-force to rivets to ensure they don't rattle or break.

Tool: Torque Wrench

Pressure Cooker Safety

For pressure vessels, we verify the Vent Weight operation and the Safety Valve release pressure. Critical for preventing explosions.

Tool: Pressure Bench
