Abstract

Embodiments of the present invention combine an open-face molding process and an injection molding process to embed decorative articles within a shaped unitary body. Two half-molds are formed, each serving both as an open-face mold alone and as components of a two-part mold in combination. An open-face molding process is performed in iterations using each half-mold, wherein during each iteration a layer of a fluid thermoset is poured into each half-mold and allowed to harden into a solid body; pits are bored into each solid body and decorative objects deposited therein; and each pit is plugged with additional quantities of fluid thermoset. Subsequent iterations may be performed over already-formed layers within each half mold. Finally, the half-molds are closed together and joined by an injection molding process, forming a unitary body having a plurality of decorative objects embedded therein.

A process comprising:

forming, under application of a curing pressure, a first half-mold having a first shaped cavity, wherein the first shaped cavity has a first brim;
performing the following steps (i)-(vi) at least once:
(i) pouring a quantity of a thermoset in fluid form into the first shaped cavity such that an unfilled remainder remains within the first shaped cavity;
(ii) curing the quantity of the thermoset in fluid form within the first shaped cavity under application of the curing pressure, such that the quantity of the thermoset in fluid form within the first shaped cavity forms a solid body within the first shaped cavity having an exposed surface not reaching the first brim of the first shaped cavity;
(iii) boring a plurality of pits, each having a bottom, into the solid body within the first shaped cavity through the exposed surface of the solid body within the first shaped cavity, without forming a substantially planar surface at the bottom of any of the pits of the plurality of pits of the solid body within the first shaped cavity;
(iv) placing an object into each pit of the plurality of pits of the solid body within the first shaped cavity;
(v) filling each pit of the plurality of pits of the solid body within the first shaped cavity with a plugging quantity of the thermoset in fluid form, such that each object within each pit of the plurality of pits of the solid body within the first shaped cavity is submerged within each plugging quantity of the thermoset in fluid form;
and
(vi) curing each plugging quantity of the thermoset in fluid form in the body within the first shaped cavity under application of the curing pressure;
forming, under application of the curing pressure, a second half-mold having a second shaped cavity, wherein the second shaped cavity has a second brim;
performing the following steps (vii)-(xii) at least once:
(vii) pouring a quantity of a thermoset in fluid form into the second shaped cavity such that an unfilled remainder remains within the second shaped cavity;
(viii) curing the quantity of the thermoset in fluid form within the second shaped cavity under application of the curing pressure, such that the quantity of the thermoset in fluid form within the second shaped cavity forms a solid body within the second shaped cavity having an exposed surface not reaching the second brim of the second shaped cavity;
(ix) boring a plurality of pits, each having a bottom, into the solid body within the second shaped cavity through the exposed surface of the solid body within the second shaped cavity, without forming a substantially planar surface at the bottom of any of the pits of the plurality of pits of the solid body within the second shaped cavity;
(x) placing an object into each pit of the plurality of pits of the solid body within the second shaped cavity;
(xi) filling each pit of the plurality of pits of the solid body within the second shaped cavity with a second plugging quantity of the thermoset in fluid form, such that each object within each pit of the plurality of pits of the solid body within the second shaped cavity is submerged within each second plugging quantity of the thermoset in fluid form;
and
(xii) curing each plugging quantity of the thermoset in fluid form in the body within the second shaped cavity under application of the curing pressure;
closing the first half-mold and the second half-mold together such that the first shaped cavity and the second shaped cavity are united to form a common cavity enclosed by the first half-mold and the second half-mold, and the unfilled remainder of the first shaped cavity and the unfilled remainder of the second shaped cavity are united to form a joint void within the common cavity;
filling the entirety of the joint void with a sealing quantity of the thermoset in fluid form;
and
curing the sealing quantity of the thermoset in fluid form within the common cavity while the first half-mold and the second half-mold are closed together under application of a curing pressure, such that the sum total of cured thermoset in fluid form within the first half-mold and within the second half-mold forms a unitary body.
