It is provided an adjustment assembly for an adjustment drive of a motor vehicle, having a first adjustment part having a first screw thread, and a second adjustment part having a second screw thread, which is in engagement with the first screw thread, wherein at least one of the screw threads has a plastic coating. The plastic coating covers more than 50% of the at least one screw thread.

The present disclosure includes a thread insert for a blow mold assembly configured to form a polymeric container. The thread insert includes: an inner mold surface defining threads, the inner mold surface configured to form a finish of the container; a first bore defined by the thread insert; and a first heating element seated within the first bore and configured to heat the inner mold surface.

The invention relates to a component (1) having a fastening region (2) for a threaded connection, wherein the component has a surface (3) having fiber material (5) embedded and integrated into a matrix (4) in at least one layer, wherein the fiber material has a fiber course substantially parallel to the surface, wherein the surface has a fastening opening (6) having a center axis (7) arranged at an angle to the surface and wherein the fastening opening is provided for an internal thread (8). In the region of the fastening opening, the fiber material lying parallel to the surface is deflected, starting from the surface, in such a way that the fiber course of the fiber material after the deflection is at an angle to the surface that approaches the direction of the center axis. Furthermore, a tube (9) is formed by means of the deflected fiber material. The invention further relates to a molded part and to a fastening part for such components.

A cap for use in covering a portion of a fastener protruding from a surface is provided. The portion includes threads. The cap includes an interior, a base that at least partially delimits the interior, a threaded receptacle on the interior configured to threadably engage the portion of the fastener, and a seal coupled to the base to engage the surface.

A pipe end protector for protecting pipe threads provided on a pipe end of a pipe component for exploration and production of a hydrocarbon well, said pipe end protector comprising a main body and an annular flexible lip seal, wherein the main body is made from a first polymeric material having a first elastic modulus, and the lip seal is made from a second polymeric material having a second elastic modulus which is lower than the first elastic modulus.

A method of mechanically securing a first object including a thermoplastic material in a solid state to a second object with a generally flat sheet portion, with a perforation of the sheet portion, and with the sheet portion having an edge along the perforation is provided, wherein the first object is positioned relative to the second object so that the edge is in contact with the thermoplastic material and wherein mechanical vibration energy is coupled into the assembly including the first and second objects until a flow portion of the thermoplastic material due to friction heat generated between the edge and the thermoplastic material becomes flowable and flows around the edge to at least partially embed the edge in the thermoplastic material. After the mechanical vibration stops, the thermoplastic material is caused to re-solidify, whereby the re-solidified thermoplastic material at least partially embedding the edge anchors the first object in the second object.

Threaded metal inserts for polymer lower receivers and hybrid polymer lower receivers comprising one or more of such inserts, as well as kits and methods therefor are disclosed. A threaded metal insert has a substantially circular aperture configured with screw threads to releasably yet connectively interface with a separate traditionally threaded firearm component such as a buffer tube or a pistol grip screw. Inserts can be any overall shape so long as it can be integrally embedded within a traditionally threaded portion of a polymer lower receiver in a way that does not interfere with normal operation of an assembled firearm and leaves exposed the internal threading of the insert. Inserts can also comprise textural features on the exterior surface configured to permanently interface with and embed the an insert into molded polymer. A hybrid polymer and metal lower receiver is a stripped polymer lower receiver for an AR type firearm, such as the AR-15 or AR-10, having one or more such threaded metal inserts at least partially embedded in a portion thereof.

The invention relates to an injection molding device for manufacturing tubes having an internal thread, having a tool that forms an article cavity, having means for filling the article cavity with a thermoplastic molding compound, having an injection device for injecting a fluid toward a projectile to be driven through the article cavity, wherein the injection device comprises a projectile carrier having at least one injection nozzle and having at least one projectile receptacle for a projectile as a displacement member for the molding compound, wherein the projectile carrier at an end that is remote from the projectile receptacle is provided with a thread-bearing stamping core which is adjustable relative to the projectile carrier between a thread-forming first position and a demolded second position, wherein the stamping core in the thread-forming position plunges into the article cavity and seals the latter.

A cleaning device for LADs, and other such threaded devices, comprising a cap and a cleaning agent. The cap comprises a casing having an opening to an interior cavity. A threaded coupling mechanism is located on the inner surface of the casing proximate the opening. The coupling mechanism has retention features that provide localized pressure points on the threads of the LAD to accommodate thread variance and reduce the chance of premature disengagement.

A method of forming a molded device, such as a stopper, requiring minimal post-molding processing includes providing a four-plate mold assembly (52) having top plate (54), a sprue/vent plate (56) including a core portion (62), a main plate (58) including a recess (66) defining a mold cavity (68) having a contoured surface (70), and a bottom plate (60), closing the mold assembly (52) such that the core portion (62) enters into the recess (66) in the main plate (58) to define a space (72) corresponding to the shape of the stopper (10, 110) to be molded. A polymeric material is introduced into the mold cavity (68) to form the stopper (10, 110). A barrier layer (14, 114) can be inserted between the main plate (58) and bottom plate and adhered to the molded device (10, 110). The plates are opened and the molded device is removed.
