Mechanical Tiger Paw

The Mechanical Tiger Paw is a new testing machine designed by GMM R&D scientists in an effort to standardize the Hand Held Tiger Paw device, and eliminate any testing subjectivity.

The machine consists of the standard Tiger Paw stylus, which rotates in 2 directions uniformly over the surface of the cookware.

The pan is heated to 400° Fahrenheit (205° Celsius) with a hotplate, and is filled with a thin layer of cooking oil. To gauge coating performance, GMM measures the time (in minutes) that it takes for the Tiger Paw to penetrate the coating film to bare metal. Please watch the video to see the Mechanical Tiger Paw in action.
