Flexible, reinforced polymeric molds for Corning simulated stone veneers is provided. The molds are formed of a single solitary unit containing a plurality of contoured wells. A flange forms an outer portion of the mold and provides a means for grasping the mold so that the mold can be folded and flipped for the extraction of the artificial stones. One or both hinge portions located transversely across the central portion of the mold may be reinforced with an embedded nylon mesh scrim. The scrim increases the tear and tensile strength of the hinge portion. Additionally, the incorporation of the nylon mesh scrim at the hinge portions increases the life of the mold and reduces the occurrence of scrap molds. The polymeric mold advantageously retains its shape after the mold has been removed from the simulated stones, which permits the mold to be used in subsequent stone-molding operations.
A mold for manufacturing stone products comprising:
The mold of claim 73 wherein one of said orthogonally extending said hinge portions is reinforced by said scrim member.
In a mold for manufacturing simulated stone products, said mold having a flexible layer defining a plurality of mold cavities, a flange portion forming a periphery of said flexible layer;
A method of manufacturing a mold for creating simulated stones, said mold having a flexible layer including a plurality of mold cavities, a flange portion forming a periphery of said flexible layer, and at least one hinge portion located between said mold cavities to permit folding of said mold between said mold cavities, comprising:
