Abstract:
A structural reinforcement for an article including a carrier that includes: (i) a mass of polymeric material having an outer surface; and (is) at least one consolidated fibrous insert having an outer surface and including at least one elongated fiber arrangement having a plurality of ordered fibers arranged in a predetermined manner. The fibrous insert is envisioned to adjoin the mass of the polymeric material in a predetermined location for carrying a predetermined load that is subjected upon the predetermined location (thereby effectively providing localized reinforcement to that predetermined location). The fibrous insert and the mass of polymeric material are of compatible materials, structures or both, for allowing the fibrous insert to be at least partially joined to the mass of the polymeric material. Disposed upon at least a portion of the carrier will be a mass of activatable material.
Abstract:
Systems and processes that limit distortion of inserts (e.g., previously formed parts) in insert molding and overmolding processes. Initially, a mold may be closed (e.g., clamped) about an insert with the mold at a first temperature. After closing the mold about the insert, the mold is heated up to a second temperature (e.g., a temperature suitable for injection of the molding material) and filled with the molding material to contact (e.g., encapsulate) the insert. After the mold has been cooled, the mold may be opened and the finished part (including the insert and the solidified molding material) removed (e.g., ejected). The process may be repeated for additional finished parts. Closing the mold about the insert before heating the mold to the injection temperature advantageously limits distortion of the insert that would otherwise occur by placing the insert into the mold with the mold already at the injection temperature.
Abstract:
A composite of metal and resin includes a metal piece and a resin piece. The metal piece includes a surface. Micropores are formed on the surface. The micropores have inlet diameters smaller than bottom diameters thereof. The resin piece is partially inserted into the micropores to combine with the metal piece.

Abstract:
A hammer or other hand tool has a head to which is attached a handle. The handle has a plurality of spring steel rods extending substantially the length of the handle and extending into the head where the rods are affixed by a plate. Spacer plates with holes are positioned at spaced locations along the rods. The rods and spacer plates are encased in a rubber material that forms the outer surface of the handle. The rods and spacer plates at the end of the handle form a reinforced lanyard hole. A collar is formed on the handle adjacent the head. The head of the hammer has angled deflecting pads adjacent the striking faces. A raised rim on the head opposite the handle forms a stand surface to enable the barrel shaped head to stand with the handle projecting upwardly.
Abstract:
An insert molded article is comprised of a thermoplastic resin molded article and a thermoplastic resin film-like body molded integrally with the molded article by insert molding. The film-like body is heated, during insert molding, to a temperature in which a secondary shrinkage factor thereof becomes equal to or larger than a shrinkage factor of the thermoplastic resin of the molded article. A manufacturing method of the insert molded article includes providing the thermoplastic resin film-like body to a concave portion of a female mold, forming a cavity of a shape capable of shaping the molded article on one surface of the film-like body, and injection molding the thermoplastic resin so that the film-like body is heated, inside the cavity, to a temperature in which the secondary shrinkage ration thereof becomes equal to or larger than the shrinkage ratio of the thermoplastic resin forming the molded article.
Abstract:
A mold structure (100) includes a press board (20), a lower mold (10) and at least one locking mechanism (40) configured for locking the press board to the lower mold. The at least one locking mechanism includes a locking element (41), a slidable block (46) and a driven apparatus (42). The locking element engages with the press board and the lower mold along a first direction. The locking element defines a locking hole (4124). The slidable block engages in the locking hole along a second direction. The driven apparatus drives the slidable block to move along the second direction for pressing the press board to the lower mold along the first direction.
Abstract:
A method of forming a polymeric component (41, 50, 51, 55) on a body (100, 200, 400) provides an open mould (501, 502) having an inner surface (503, 504). The mould is placed onto a surface (401) of the body (400 so that a closed cavity (505) is formed by the inner mould surface and the body surface. A fluid polymeric material is introduced into the closed cavity which is caused to harden to form the polymeric component as a casting on the body.
Abstract:
The device includes: a runner block arranged at a position close to the injection port for resin material for secondary forming; and a slide core moved relatively with the runner block. In the runner block, a guide passage is formed which is communicated with a passage formed when pipe-shaped passages of the primary moldings are butted against each other. A heating medium passage or a resin material passage formed in the slide core are moved so that either the heating medium passage or the resin material passage can be selectively communicated with the guide passage formed in the runner block.
Abstract:
A decoration sheet is fed on a mold and then is heated to a temperature above a heat distortion temperature thereof, is conformed to the surface of a cavity of the mold by vacuum drawing. Then the molds are clamped, and a resin is injected to adhere the decoration sheet to the resin. The decoration sheet is preheated to a temperature below the heat distortion temperature by sheet preheating means before fed onto the mold. The decoration sheet preheated by the sheet preheating means is fed to the mold by sheet feeding means.
