An article is molded from first and second thermosetting elastomer compositions each comprising free-radically curable elastomer and free radical initiator but different from one another. The first thermosetting elastomer composition is molded to fill a first area of a mold cavity at a first temperature at which the first free radical initiator has a half-lifeabout 10 minutes or at which the first thermosetting elastomer composition has an increase in torque less than 10% of a total increase in torque at full cure. The second thermosetting elastomer composition is then inserted into the mold cavity, and the mold is heated to fully cure the article, for example a temperature at which each free radical initiator has a half-lifeabout 1 minute, with the second composition filling a second area of the mold cavity before or during heating and curing.

A bite-proof spout is disclosed which contains multiple durometer material, such that the higher durometer material is in closer contact to the mouth of a user to be able to withstand biting without undue deterioration than the lower durometer material which is positioned further away from the mouth.

An implantable medical device is disclosed comprising a thermoplastic composite body having anterior, first lateral, second lateral, posterior, superior, and inferior surfaces, and at least one dense portion and at least one porous portion which are integrally formed. The at least one dense portion is formed of a first thermoplastic polymer matrix that is essentially non-porous, and which is continuous through a thickness dimension from the superior surface to the inferior surface. The at least one porous portion is formed of a porous thermoplastic polymer scaffold having a second thermoplastic polymer matrix which is continuous through the thickness dimension. A method for forming the thermoplastic composite body is disclosed comprising disposing a first powder mixture in a first portion of a mold, disposing a second powder mixture in a second portion of the mold, simultaneously molding the first powder mixture and the second powder mixture, and leaching porogen.

The present invention relates to a method and device for manufacturing artificial marble. According to the present invention, artificial marble having a stripe pattern similar to that of natural stone, such as striato, may be provided.

A method for patterning a foam pad includes transversely cutting the foam pad so that the foam pad has a cut surface; covering the cut surface with a dye paper on which a predetermined pattern is formed using a dye, performing a first hot press process on the dye paper so that the dye on the dye paper is vaporized and transferred to the cut surface, and removing the dye paper; applying a transparent PU resin onto the cut surface that has been dyed, and curing the PU resin; and performing a second hot press process on the PU resin on the cut surface, so that the cut surface is increased in density and the PU resin encloses the dye, thereby making the dye firmly attached to the cut surface.

A chew toy product is made of multiple layers of silicone. Liquid silicone layers are vulcanized to a solid silicone layer to form a unitary solid silicone chew toy. Each of the layers can include a silicone colorant, so the chew toy can have multiple colors.

The present invention is an ergonomic silicone wedding ring comprising of 3 bands which are designed not to separate easily and are thinner, more ergonomic and comfortable than prior silicone tri-band rings.

A method of manufacturing a silicone ring consisting of two outer-band halves formed by compression silicone-molding in a first mold and an inner-band formed by placing half of the outer-bands of the ring in a second mold, placing a spacer-insert mold over the second mold, inserting a silicone rubber in the cavities of a spacer-insert mold, inserting the remaining outer-band halves into a fourth mold, inserting the three molds into a compression chamber to vulcanize the outer-band halves and the inner-band together, wherein the first and second outer-bands form a complete ring, and a symmetrical inner-band is formed in between the first and second outer-band halves.

The present invention relates to a method and device for manufacturing artificial marble. According to the present invention, artificial marble having a stripe pattern similar to that of natural stone, such as striato, may be provided.

A panel includes a thermoset material, and an image comprising sublimation ink. The sublimation ink is absorbed in the thermoset material. The rigid component may be a rigid structure formed by the thermoset material. The panel may be for a bath or shower enclosure.
