A laser welded structure is formed by laser welding together a resin molded body formed from a thermoplastic polymer alloy containing a crystalline resin and an amorphous resin and a metal body made of a metal. A glass transition temperature of the amorphous resin is lower than a melting start temperature of the crystalline resin.

The present invention relates to a motor vehicle luminous device including at least one first portion that is transparent to at least one laser beam, the portion having at least one first polymer material, and at least one second portion that absorbs the laser beam and is transparent to at least some of the visible spectrum, including at least one second polymer material, the second portion being laser welded to the first portion.

A method of manufacturing a transport refrigeration unit is provided. The method includes providing an enclosure including an outer layer and a supporter. Providing the enclosure includes supplying one of a first material and a second material to a mold. This also includes supplying the other of the first material and the second material on the one of the first material and the second material that is supplied to the mold. Also, this includes curing the first material and the second material integrally that are supplied to the mold. The first material forms into the outer layer and the second material forms into the supporter. The second material includes a plurality of reinforcing fibers.

The present disclosure relates to a surface-modifiable injection-molded body comprising a thermoplastic polymer matrix and second polymer material at least in parts, in which the polymer matrix and the second polymer material have different weight average molecular weights and polarities, and the second polymer material is an adhesive. The present disclosure also relates to a method for its production.

A first object is anchored in a second object. The first object has a material with thermoplastic properties, and the second material has a material that is solid and is penetrable by the first material when in a liquefied state. The second object has an insertion face with an opening having a mouth in the insertion face, and the first object has an insert portion that for anchoring is placed in the opening or about the mouth thereof. For anchoring, energy suitable for liquefaction of the first material impinges in an amount and for a time sufficient for at least partial liquefaction of the first material and interpenetration of the first and second materials. The second object, around the opening, has an anisotropic strength with respect to forces perpendicular to the opening axis.

A joining element has an anchoring portion for in-depth anchoring in the object and a head portion arranged proximally of the anchoring portion with respect to an insertion axis. The head portion has a lateral outer surface that has a structure that is well-defined, especially within tight tolerances. The joining element is positioned relative to an object of a non-liquefiable material such that the anchoring portion reaches into an opening of the object or is placed adjacent a mouth thereof. Then, the joining element is pressed towards a distal direction, to press the anchoring portion into the opening, while mechanical vibration energy is coupled into the joining element by a tool, in an amount and for a time sufficient for liquefaction of a portion of the thermoplastic material to cause interpenetration of the thermoplastic material into structures of the object.
