According to one implementation, a preform shaping method for producing a preform having a web, a flange, and a chamfered portion includes: pressing a first portion of a laminated body of fiber sheets by sandwiching the first portion between a first mold and a second mold; and pressing a second portion of the laminated body of the fiber sheets after pressing the first portion. The first portion corresponds to the web. The second portion corresponds to the flange. The first mold fits a surface in one side of the web, an inner surface of the chamfered portion and a surface in one side of the flange. The second mold fits a surface in the other side of the web. The second portion is pressed by sandwiching the second portion between the first mold and a third mold.

A reusable countertop mold in accordance with the present invention includes at least one mold sheet, but generally a plurality of mold sheets are required to extend about a predetermined portion of a periphery of a floor mounted cabinet. The mold sheet is dimensioned and configured to ultimately form a countertop having a predetermined configuration with predetermined dimensions. The mold sheet includes a relatively thin base portion and a wall portion perpendicular to the base portion. The reusable countertop mold further includes a plurality of fastener recesses in an inner side portion of the base portion, the recesses ultimately allowing fasteners to pass through a countertop substrate and into the floor mounted cabinet, after the base portion has been inserted between the countertop substrate and the cabinet. After a countertop forming material has hardened upon the countertop substrate and the mold sheet, the base portion of the mold sheet is slidably removed from between the countertop substrate and the cabinet, thereby allowing the reusable countertop mold to be reused for another countertop forming project.

An apparatus for molding a composite material comprising a plurality of mold pieces that cooperate to form a mold having a mold cavity for molding a composite part, the plurality of mold pieces split along a plurality of part lines configured to reduce voiding, the plurality of part lines comprising part lines running from a plurality of voiding areas of the mold cavity to an outer surface of the mold and adapted to provide bleed lines for the plurality of voiding areas.

A functional polymeric cutting edge structure and methods for manufacturing cutting edge structures using polymeric materials are provided. A razor blade for use in a razor cartridge or a blade box for assembly in a razor cartridge frame may be formed using the present invention.

A molding method and a molding system for improving a molding speed of a resin molded member. In the method, firstly a thermoplastic resin composite material is filled in a metal mold (i.e., at time T0), and subsequently a mold-clamping process gets started. As the mold-clamping process progresses, a first decompression circuit starts to decompress an inside of a cavity when the cavity is closed by a sealing member provided on the metal mold. Then, as the mold-clamping process further progresses, the thermoplastic resin composite material thus filled in the metal mold contacts an upper mold of the metal mold (i.e., at time T2). After that, a second decompression circuit starts to decompress the inside of the cavity, thereby to complete the mold-clamping process (i.e., at time T3).

A mold design having a non-symmetric tread ring parting line is described that forms a tread pattern that extends onto the off-shoulder area of a tire on one side. The mold has a single tread segment that forms the entire tread pattern on the tire. The tread segment of the mold is non-symmetric in that one end, a first end, extends farther downward than the opposite end, a second end. The first end of the tread segment contains a tread pattern design capable of imparting a tread design on the off-shoulder or sidewall of one side of the tire to form a non-symmetric tread pattern.

A mold for manufacturing a wind turbine blade, including: a lower mold component, and an upper mold component, wherein the lower mold component and the upper mold component form a mold cavity in the shape of a wind turbine blade, and the upper mold component includes at least two upper mold parts is provided. The required floor-to-ceiling height of a production hall is decreased and the required lifting capacity of a crane is lowered.

A tire vulcanization mold disclosed herein includes sectors 13 divided in a tire circumferential direction and molding a tread portion 1 of a tire, and a pair of upper and lower side plates 11 and 12 molding a sidewall portion 2 of the tire. Mold parting lines 16a and 17a formed by the sectors 13 and a pair of the upper and lower side plates 11 and 12 are located in the tread portion 1 and set to pass a bend point 8c of a surface design in the tread portion 1.

A tyre mold for curing and molding a tyre includes a plurality of tread segments for molding a tread rubber of the tyre. The plurality of tread segments, upon being connected with one another in a mold circumferential direction, forms a tread molding-surface that is substantially continuous in the mold circumferential direction through parting lines that appear between adjacent tread segments. The parting lines include one or more inclined parting lines inclined with respect to a mold axial direction, and the inclined parting lines extend straightly between ends in the mold axial direction of the tread molding-surface.

A device for machining a plate-shaped workpiece for a motor vehicle comprises a lower tool with a holding region for the workpiece, and a folding element which has a holding region for the workpiece and which is movable relative to the lower tool. The folding element (40) can change from a first state into a second state and can thereby form a first cavity between the holding region of the folding element and the workpiece.
