Embodiments herein include a system for joining components. The system can include a rotating base platform, a plurality of receptacles mounted to the base platform, and a rotating sonotrode platform. A plurality of sonotrodes are mounted to the sonotrode platform. Each sonotrode can correspond to a receptacle. Each sonotrode can move in a reciprocating motion between a release position distant from a corresponding receptacle and a compressing position proximal to the corresponding receptacle. The compressing position occurs at a first angular position of the sonotrode platform. Each sonotrode is energized at the compressing position.

Various embodiments relate to plastic-metal junctions and methods of making the same via laser-assisted joining. The present invention provides a method of forming a junction between a metal form and a solid plastic. The method can include laser treating a surface of a metal form to generate a feature (e.g., a plurality of at least one of pores and grooves) in the surface of the metal, wherein the laser has an angle of incidence with the surface of the metal of other than 0 degrees. The method can include contacting the metal surface including the feature with a flowable resin composition. The method can include curing the flowable resin composition to form the solid plastic, to provide the junction between the metal form and the solid plastic.

According to an aspect of the invention, a method of mechanically securing a first object (1) comprising a thermoplastic material in a solid state to a second object (2) with a generally flat sheet portion, with a perforation (20) of the sheet portion, and with the sheet portion having an edge (21) 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 comprising 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 resolidified thermoplastic material at least partially embedding the edge anchors the first object in the second object.

The present invention is generally directed to prepreg composites, typically in the form of unidirectional tapes, which contain at least one reinforcing fiber and a thermoplastic polyester matrix. The prepreg composites can be thermally bonded to a wood-containing material in order to improve the structural performance of the material without requiring adhesives. The prepreg composite of the present invention can be applied to a wide range of wood substrates, including various hardwoods, softwoods, and engineered wood composites.

A venting apparatus (100) is disclosed herein. The venting apparatus comprises a substrate (102), such as a metal substrate or a specialty plastic substrate, having an opening (104) therein and a fluoropolymer membrane (106), such as ePTFE, disposed over said opening and thermally bonded using a thermoplastic material (110) to said substrate. This allows the fluoropolymer membrane to be directly bonded to the said substrate without using an adhesive layer.

Method for forming a sealing element from extruded thermoplastic rods (1) comprises the steps of machining one or more extruded thermoplastic rods, each having a first and a second end (5,6), in a desired shape; bending the one or more machined thermoplastic rods into a circular structure at ambient temperature while keeping the stress in the one or more thermoplastic rods below the yield point; joining the first and second end faces (2,3) of the thermoplastic rods to form the sealing element. The invention also relates to a method for replacing and repairing a sealing element of a swivel.
