Processed slabs, and systems and methods related thereto
This document describes systems and processes for forming synthetic molded slabs, which may be suitable for use in living or working spaces (e.g., along a countertop, table, floor, or the like).
1. A system for forming a processed slab using a combination of different particulate mineral mixes, comprising:
a slab mold defining a mold space that is at least 6 feet long by at least 3 feet wide;
two or more reusable stencils including one or more top walls, the top walls defining complementary patterns of open spaces and occluded spaces, each stencil configured to prevent a particulate mineral mix from entering a respective occluded space when a respective stencil is in the slab mold, the cumulative areas of the open spaces of the stencils substantially corresponding to the mold space; and
two or more mineral aggregate distributors that are each configured to dispense a corresponding particulate mineral mix through the open spaces of a corresponding one of the stencils into the slab mold.
2. The system of claim 1 , wherein the two or more stencils comprise a first stencil defining a first pattern of open spaces and a first pattern of occluded spaces, and a second stencil defining a second pattern of open spaces corresponding to the first pattern of occluded spaces and a second pattern of occluded spaces corresponding to the first pattern of open spaces.
3. The system of claim 2 , wherein the second pattern of open spaces is an inverse of the first pattern of open spaces.
4. The system of claim 2 , wherein the first pattern of open spaces do not overlap the second pattern of open spaces.
5. The system of claim 1 , wherein the two or more mineral aggregate distributors comprise at least a first mineral aggregate distributor configured to dispense a first particulate mineral mix and a second mineral aggregate distributor configured to dispense a second particulate mineral mix, wherein the first particulate mineral mix and the second particulate mineral mix comprise two differently colored mineral mixes that each include a quartz material, one or more pigments, and at least one binder.
6. The system of claim 1 , wherein the two or more stencils provide at least a first predefined pattern of open spaces and occluded spaces and a second predefined pattern of open spaces and occluded spaces.
7. The system of claim 6 , wherein the first predefined pattern defines a first pigmented vein and the second predefined pattern defines a second pigmented vein of a slab.
8. The system of claim 7 , wherein at least a portion of the first pigmented vein at least partially surrounds at least a portion of the second pigmented vein.
9. The system of claim 7 , wherein the first pigmented vein extends through an entire thickness of the slab at a first set of regions where the second pigmented vein is absent, and the second pigmented vein extends through the entire thickness of the slab at a second set of regions where the first pigmented vein is absent.
10. The system of claim 9 , wherein the two or more mineral aggregate distributors further comprise a third mineral aggregate distributor configured to dispense a third particulate mineral mix into the slab mold according to a third predefined pattern.
11. The system of claim 10 , wherein the third predefined pattern defines a third pigmented vein that extends through an entire thickness of the slab at a third set of regions where the first and second pigmented veins are absent.
12. The system of claim 10 , wherein the third predefined pattern overlaps with the first and second predefined patterns such that the third pigmented vein does not extend through an entire thickness of the slab.
13. The system of claim 1 , wherein the two or more stencils and the two or more mineral aggregate distributors are configured to sequentially dispense at least two of the same differently colored particulate mineral mixes into each mold in a series of molds according to a predefined and repeated pattern for each mold in the series of molds so as to define complementary regions of multiple different particulate mixes having generally the same appearance in each mold in the series of molds.
14. A system for forming a processed slab using a combination of different particulate mineral mixes, comprising:
a slab mold defining a mold space that is at least 6 feet long by at least 3 feet wide;
two or more reusable stencils defining complementary patterns of open spaces and occluded spaces, the cumulative areas of the open spaces of the stencils substantially corresponding to the mold space;
a first mineral aggregate distributor configured to dispense a first particulate mineral mix through the open spaces of a first stencil into the slab mold; and
a second mineral aggregate distributor configured to dispense a second particulate mineral mix that is differently colored than the first particulate mineral mix through the open spaces of a second stencil into the slab mold;
wherein the first and second mineral aggregate distributors are configured to dispense the first and second particulate mineral mixes into each mold in a series of molds according to a predefined and repeated pattern for each mold in the series of molds so as to define complementary regions of first and second particulate mineral mixes having generally the same appearance in each mold of the series of molds.
15. The system of claim 14 , comprising first and second stencils that define complementary patterns of open spaces and occluded spaces, the cumulative areas of the open spaces of the stencils substantially corresponding to the mold space, the first mineral aggregate distributor configured to dispense the first particulate mineral mix through the first stencil and the second mineral aggregate distributor configured to dispense the second particulate mineral mix through the second stencil.
16. The system of claim 14 , wherein the first stencil comprises a first predefined pattern of open spaces and occluded spaces, and the second stencil comprises a second predefined pattern of open spaces and occluded spaces.
17. The system of claim 16 , wherein the first and second particulate mineral mixes comprise two differently colored mineral mixes that each comprise quartz, a pigment, and a binder.
18. The system of claim 15 , wherein the first predefined pattern defines a first pigmented vein and the second predefined pattern defines a second pigmented vein.
19. The system of claim 18 , wherein the first pigmented vein extends through an entire thickness of the slab at a first set of regions where the second pigmented vein is absent, and the second pigmented vein extends through the entire thickness of the slab at a second set of regions where the first pigmented vein is absent.
20. The system of claim 14 , further comprising a third mineral aggregate distributor configured to dispense a third particulate mineral mix into the slab mold according to a third predefined pattern.
21. The system of claim 20 , wherein the third predefined pattern overlaps with the first and second predefined patterns such that the third pigmented vein does not extend through an entire thickness of the slab.
