Abstract

See full text

Improvements in composite shingle manufacturing are realized through the use of an acid etching solution along with machining to generate a molding surface particularly well suited for the molding of shingles having the look of 'natural' materials, such as slate. Upon the selection of a specific pattern that will define the primary shape for molded composite shingles, machine tools are used to cut the pattern into the base mold to form a molding surface. Finer details are then added to the molding surface through the use of an acid etch solution. The base mold with the sculpted molding surface may then be used in traditional molding techniques to produce composite shingles having an exposed surface that closely replicates the appearance of naturally occurring materials.
