A molding system for forming a composite structure having trapped volumes is presented. The molding system comprises a plurality of removeable inserts, a bottom tool assembly, and a plurality of vents formed at a parting line of the molding system. Each removeable insert of the plurality of removeable inserts comprises a plurality of pieces configured to be disassembled for removal from the composite structure. Each removeable insert is configured to be placed in contact with the bottom tool assembly.

Systems and methods are provided for securing laminates to mandrels. One embodiment is a method for facilitating layup of preforms, the method including selecting a mandrel that includes at least one receptacle, disposing a first vacuum bag atop the mandrel that covers the receptacle, selecting a Ply Location Template (PLT) that includes a securement element, aligning a portion of the securement element with the receptacle, pressing the portion of the securement element downward into the first vacuum bag and driving the portion of the securement element into the receptacle, and abutting a preform against the PLT.

A method of manufacturing a medical component includes molding a first member of the medical component from an elastomeric material. The first member includes a first end defined by a closed base wall, an opposing second end which is an open end, a sidewall extending between the first and second ends, and an internal recess to receive at least one electronic device. The method further includes positioning the electronic device within the recess of the first member to form an assembly, such that the electronic device is received in an inverted open cavity defined by the sidewall. The method further includes applying a protective film on the second end of the first member, such that the protective film covers an exposed surface of the electronic device. In addition, the method includes overmolding the assembly with the elastomeric material to form the medical component having the electronic device embedded therein.

A molding tool includes a top die, a bottom die, and several middle dies. Each middle die has a molding hole. The top die or the bottom die has a core, and the other one has a partial cavity. The partial cavity and each molding hole jointly form a cavity matching the core. The top die is opposite to the bottom die. The top die and/or the bottom die are/is driven to move towards or away from each other. Each middle die is moved to a position between the top die and the bottom die, allowing each middle die to be clamped with the top die and the bottom die. Upon using, a raw material is disposed on each middle die before the middle dies being sequentially moved to the position, making the top die, the bottom die, and the middle die clamp to process the raw material into a product.

The rolling bearing seal includes a core metal and rubber adhered to the core metal by vulcanization. The rubber includes: a seal lip portion having, over the entire circumference in the circumferential direction, a plurality of projections that extend inward in the radial direction from the inner diameter side of the core metal, and slides on a seal sliding surface of an inner ring of a rolling bearing; and an attachment portion that is attached to an outer ring of the rolling bearing. A compression vulcanization molding mold includes a female mold and a male mold. The female mold has a guide portion for positioning the core metal and a rugged shape forming the projections on the seal lip portion. The male mold has an inner-diameter-side burr groove and an outer-diameter-side burr groove and the shape of a radially outermost portion of the inner-diameter-side burr groove is formed in a circle.

A modular highway warning strip system which comprises a modular warning strip segment having first and second ends, a length extending between the first and second ends, two opposing lengthwise sides, a width extending between the opposing lengthwise sides of the segment, top and bottom surfaces, and a thickness. Each of the first and second ends comprise at least one male protrusion and at least one female receptacle, wherein the at least one male protrusion is configured to engage the at least one female receptacle for joining a plurality of the segments together end-to-end. A segmented metallic plate is disposed between upper and lower rubber layers, the segmented plate comprising a plurality of segments separated by slits comprising living hinges.

A manufacturing method is provided. A preform is arranged over a surface of an inner mold line. The preform is folded over sides of the inner mold line. An end of the preform is clamped to a floating plate using a bladder-activated clamp. The floating plate is translated in a first direction to tension the preform into a shaped body. A plurality of compressing bladders are activated to apply compressive forces to the preform.

A device and a method for manufacturing an emblem of thermoplastic synthetic resin with an incorporated IC chip by high frequency dielectric heating without damaging the IC chip, the device including: an upper metal mold having with a fusion cutting blade; a support frame along the perimeter and upper surface of the table; a slide board on top of the table that is slidable in axial directions relative to the table; a metal plate on the upper surface of the slide board; wherein pressing the upper layer material with the mold from above and subjecting the material to high frequency dielectric heating, the IC chip is placed in an upper position of the recessed section, then the slide board is driven to slide below the mold and subsequently the heating operation is executed without any risk of applying pressure onto the IC chip.

Three-dimensional decorative articles are produced from blanks of heat-shrinkable plastic sheet material, using a mold base having an outer surface with a recess over which a blank is placed, and a convex mold insert that moves into the recess by gravity as the blank softens and cooperates with the interior wall of the recess to shape the sheet material into a three-dimensional decorative article. A guide peg extends outward from the bottom of the recess past the outer surface of the mold base and extends through a hole formed in the blank, and through a guide hole in the mold insert to support the mold insert before heating and to guide the mold insert as it moves into the recess of the mold base.
