A torque converter includes an impeller, a turbine, a stator, a one-way clutch, and an insert molded thrust washer formed onto a retention mount that is integrally formed on one of the impeller, the turbine, the stator, and the one-way clutch. The retention mount defines an undercut. At least a portion of the insert molded thrust washer is disposed within the undercut. Interference between the retention mount and the insert molded thrust washer mounts the insert molded thrust washer to the retention mount.

Provided are a speaker module and a manufacturing method therefor. The speaker module comprises a housing and a speaker unit comprising a vibrating diaphragm component and a magnetic circuit component. A front acoustic cavity and a rear acoustic cavity are formed between the speaker unit and the housing. An elastic element is provided on the housing and coupled to the end surface of an open end of the front or rear acoustic cavity. Use of the speaker module can reduce a step of manual fitting of the elastic element, ensure precision and stability, so that the elastic element is not prone to fall off, and tightness between sound outlet hole of the speaker module and sound hole of mobile phone can be ensured. The manufacturing method for the speaker module also can be extended to manufacturing of other structures requiring injection of a soft or rigid material into another material.

A method for producing a metal-plastic composite part having a plastic component and a metal component. A microstructure is produced in a contact face of the metal component, wherein the microstructure has undercuts in relation to the contact face. The metal component is arranged in an injection mold such that the plastic material of the plastic component can be injection molded over the contact face of the metal component. The plastic component is injection molded, wherein some of the liquid plastic material penetrates into the undercuts of the microstructure or encloses the same. The plastic material of the plastic component is cooled to form an interlocking and/or friction connection between the plastic component and the metal component.

A shock-absorbing or vibration-absorbing assembly includes a metal base and an elastic shock-absorbing or vibration-absorbing material secured to the metal base. A top surface of the metal base has at least one orifice extending from the top surface to at least one hollow chamber beneath the top surface. The hollow chamber occupies a planar area of the metal base parallel to the top surface that is larger than a planar area of the metal base that is occupied by the orifice at the top surface. The elastic material is secured to the metal base by the elastic material filling the orifice and the hollow chamber of the metal base and the elastic material filling a region above the top surface of the metal base that has a cross-sectional area parallel to the top surface of the metal base that is larger than the planar area of the metal base that is occupied by the orifice at the top surface of the metal base. The elastic material is secured to the metal base by placing the metal base against a mold having a hollow space to be filled with the elastic material. The elastic material is injected into the hollow chamber and orifice of the metal base and into the hollow space of the mold. The mold is removed from the metal base, so that the elastic material is secured to the metal base by the elastic material filling the orifice and the hollow chamber of the metal base and the elastic material filling a region above the top surface of the metal base that corresponds to the hollow space of the mold.

A golf flagstick device comprising a rigid support member combined with a plurality of jacks. The components are encapsulated by a material, such as a thermoplastic or thermosetting polymer, using an injection molding process. The jacks have one or more arms extending outward from a center portion. The arms are adapted to contact the inner wall of the mold's cavity to help hold the rigid support member in one place and away from the inner wall during the molding process. The flagstick includes a ferrule attached to a lower end which is adapted for placement into a putting cup and a tip fitting attached to an upper end which is adapted to be combined with a flag. The ferrule and/or tip fitting may be combined with the rigid support member before the injection molding process resulting in the ferrule and/or tip fitting being at least partially filled with and/or encapsulated by the material to help hold the components together without requiring a secondary attachment operation.

A method for joining sides of a speaker enclosure includes affixing a speaker grill element to a substructure element, where the speaker grill element has a depth that is shorter than its length and width, includes a first surface and a second surface parallel to each other, and includes hole openings, where the substructure element has a depth that is shorter than its length and width, includes protrusions above its front surface, and includes openings larger than the openings in the speaker grill element, and where the speaker grill element is aligned lengthwise to a first plane, inserting the joined speaker grill element and substructure element into a mould, where in combination with portions of the speaker grill element and the substructure element, a surface of the mould forms a mould cavity, and injecting molten plastic into the mould cavity to form an injection moulded side element.

A process is disclosed to encapsulate the exterior surface of a metal drinking cup or other similar heat resistant container with plastic material such as polybutylene terephthalate in an injection molding process. A fixture holds a metal container in place and is inserted within a mold. Plastic material is then injected into the mold and surrounds the exterior surface of the container and allowed to cool. The container includes various physical features on its exterior to prevent the slipping of the plastic material off of the cup after cooling. Using an injection molding process to surround and encapsulate the exterior surface of a metal container with plastic results in a thicker surface over the container, and creates an ideal platform for receiving high resolution images and designs for impregnation using a further dye sublimation process.

A wheel assembly, a wheeled device and a method of manufacturing a wheel assembly. The wheel assembly includes a core and an outer portion coupled to the core. The core includes a body and one or more projections extending from the body. Material of the outer portion may be positioned radially between the body and a portion of the projection to limit radial movement of the outer portion relative to the core. The projection may define a bore and/or an undercut. Material of the outer portion may encompass the projection and fill the bore and/or the undercut. Engagement of the material of the outer portion and the projection(s) may limit relative movement between the core and the outer portion radially, axially, circumferentially, etc.
