Abstract:
A process for producing molded products having portions formed with two separate materials is provided. The process involves forming a first component over a structural core in a first step, and forming a second component that is secured to the first component and the core in a second step. The second component can be formed directly over the first component or can be secured thereto after formation. The first and second components can additionally be formed with indicia thereon, or with recesses within which inserts containing the desired indicia can be positioned. Additionally, the first component can be formed with a ridge disposed on a projection formed on the first component that effectively seals off a portion of the first component when the second component is formed around the core and the first component to ensure the portion of the first component surrounded by the ridge remains visible after formation of the second component.
Abstract:
A lead connector for an implantable medical device includes a cylindrical connector body having a proximal end and a distal end. A distal frame forms the distal end and a remainder of the connecter body is a mold material. A plurality of shafts extending through the distal frame from a rear face to a front face, the rear face abutting the mold material forming the remainder of the connector body. A plurality of ring contacts are in the connector body. A plurality of wires are coupled to a ring contact and extend through the mold material and through a corresponding one of the shafts. The mold material forming the remainder of the connector body extends partially into each shaft and about the corresponding conductive wire to form a plug.
Abstract:
A lumbar support device comprises a carrier, a pair of arching elements molded to the carrier, and a support basket supported by the pair of arching elements. To produce the lumbar support device, the pair of arching elements may be molded to the carrier in a molding tool and the support basket may be formed in the same molding tool.
Abstract:
A method joins wire assemblies to define a wire harness by providing a mold assembly having a plurality of surface features therein to define an overmold structure. A portion of at least two individual and unconnected wire assemblies is placed into the mold assembly. The mold assembly is closed. During a molding process, uncured material is injected into the mold. The material is permitted to cure to define the overmold structure fixed to and joining the at least two wire assemblies. The portions of the wire assemblies are removed from the mold with the overmold structure thereon to define a wire harness, with opposing ends of the wire assemblies being free from covering by the overmold structure.
Abstract:
A system and process for making an eyeglass temple co-injection molded with a wire core are disclosed. An eyeglass temple is produced by injecting a first shot of temple substrate material into a mold followed by the shot injection of a portion of wire core into the substrate material while it is still molten or semi-molten followed by a second shot injection of additional molten or semi-molten material to completely fill the mold. The first shot of template substrate is provided in a viscosity and amount sufficient to support the wire core without contact by the mold or external support, and the second shot is provided in an amount sufficient to completely fill and pack the mold and lessen shrinkage problems during substrate cooling and hardening. This produces an eyeglass temple in a desired configuration having an entirely encased wire core. Optionally, a second material can then be overmolded onto portions of the temple. The first material and reinforcing core allow greater adjustability and increased comfort for the wearer, while the second material can either be softer to provide a more comfortable fit and feel or can be similar to the first material to improve the temple's aesthetics.
Abstract:
A strain relief for a coaxial cable and coaxial connector interconnection is provided as an injection moldable polymer material surrounding the interconnection. The injection moldable material fills a solder pre-form cavity between an outer conductor of the coaxial cable and an inner diameter of a bore of the connector body. Where the outer conductor is corrugated, the polymer material may be provided covering an exposed portion of the corrugations and/or filling portions of a corrugation trough between an outer jacket and the outer diameter of the outer conductor.
Abstract:
The connector terminal includes a press-fit terminal and a shaft portion, the connector terminal being fabricated of a single metal sheet, the shaft portion having a lateral cross-section having a size entirely covering therewith a lateral cross-section of the press-fit terminal when viewed in an axial direction of the connector terminal, the shaft portion having surfaces extending in the axial direction at an entire circumference thereof, the lateral cross-section of the shaft portion being identical in shape with a lateral cross-section of a terminal space of a die used for fabricating a housing for the press-fit terminal, the press-fit terminal being fit into the terminal space when the housing is molded with resin.
Abstract:
A mine support includes an elongate metal member and a coating comprising post-consumer recycled thermoplastic disposed on the member. The thermoplastic may include post-consumer recycled poly(ethylene terephthalate), and the coating may be an injection molded coating. A first layer of the coating may be provided with a thickness at least about 0.1 mm and a crystallinity between about 16% and about 30%, and a second layer of the coating may be provided with a thickness at least about 0.1 mm and a crystallinity between about 6% and about 14%. Either the first layer or second layer may contact the elongate metal member.
Abstract:
A method of manufacturing a bonded metal assembly having a form and a powdered metal-filled plastic member with a cylindrical surface generally surrounding the form includes providing a mold having a cylindrical interior surface corresponding to the cylindrical surface of the resulting powdered metal-filled plastic member and providing a gate to the mold. The gate extends at least partially along a radius of the cylindrical interior surface of the mold. With the form positioned in the mold, a powdered metal-filled plastic material is injected through the gate to the mold and flowed around the form. A resulting bonded metal assembly includes a form and a powdered metal-filled plastic member having a cylindrical surface generally surrounding the form. The powdered metal-filled plastic member includes an injection-molding gate line extending at least partially along a radius of the cylindrical surface.
Abstract:
A syringe is provided with a needle that includes a needle tube having a needle tip that can puncture a living body, a needle holding member, and an outer tube that is filled with a drug. The needle holding member is formed integrally and coaxially with the needle tube by insert molding. The needle holding member has a distal end and a proximal end, and can hold the needle tube in a state where the needle tip of the needle tube is protruded from the distal end. The outer tube is fixed to the needle holding member by welding. The needle holding member and the outer tube are formed from essentially the same material.
