Abstract
Apparatus and method for marking plastic panels which then are capable of being laminated at temperatures above 500.degree. F. These panels can be marked before or after being formed. The marking method is accomplished with the use of fluid pressure for directing a mixture of a particulate abrasive material and particulate coloring material under high pressure toward and onto a surface of a plastic panel to be marked. The coloring material particles are of sufficiently small particle size to coat the abrasive particles, so that the coloring material is carried by the abrasive material particles toward and onto the surface to be marked at high speed. When the coated abrasive particles strike the surface to be marked, the colored particles are effectively embedded below the surface of the plastic surface and in position so that they cannot be removed by cleaning detergents and the like. The abrasive particles rebound from the plastic member after depositing the colored coating therefrom, following which the plastic member is permanently marked with the coloring material and with a desired design.
