Abstract
A new technique for efficiently manufacturing jewelry includes the use of a universal frame in combination with a low cost flexible mold. Various inserts can also be used to customize jewelry pieces made using the mold and frame. The material cured in the mold can be cured with ultraviolet light, which penetrates the mold, the mold frame and an arbor, which transmit ultraviolet light to better cure the item being molded.
Claims8
For use in the molding of an item, an apparatus including:
- a master frame, made of a material capable of transmitting ultra violet light, including an injection port and two halves, each half having an inner face and a mold area so when the two halves are joined together with their inner faces in face-to-face registration a mold cavity is formed by the mold areas of the two halves, and
- a silicone mold, made of a material capable of transmitting ultra violet light, insertable into the mold cavity of the master frame and supported by the master frame so that material injected through the injection port can flow into said silicone mold to form an item shaped by the silicone mold,
- and an arbor, wherein said master frame also includes an arbor cavity for receiving said arbor and said silicone mold includes an opening so that the silicone mold can be slipped over said arbor, such that ultraviolet light can penetrate the master frame and the silicone mold to cure the item being molded from the outside of the item being molded.
A method for molding an item, said method including the following steps:
- providing a master frame, made of a material capable of transmitting ultraviolet light, separable into at least two parts, said master frame including an injection port, a mold cavity, and an arbor cavity;
- providing a silicone mold insert, made of a material capable of transmitting ultraviolet light;
- providing an arbor;
- enclosing said silicone mold and said arbor within the mold cavity of said master frame;
- injecting through said injector port and into said mold a material that sets up when exposed to ultraviolet light;
- and
- exposing said material to ultraviolet light via said master frame and silicon mold.
