Abstract: An injection mold for producing a sprinkler head part and related injection molding methods are described. The sprinkler head part includes a first, second, third and fourth mold portions. The first and second mold portions include first and second shaping elements structured to cooperatively form a body including a substantially cylindrical portion and a substantially planar portion, and two frame arms extending from the substantially planar portion of the body. The third mold portion includes a shaping element structured to form an orifice in the body of the sprinkler head. The fourth mold portion includes a shaping element structured to form a cross member connecting the two frame arms. The injection methods include injecting a composite material in molten form into the mold to form the molded sprinkler head part. The composite material includes thermoplastic polymeric resin and a plurality of reinforcing fibers dispersed in the resin.

Abstract: A method of forming at least one channel within a substrate includes coupling a fitting to a mold, and securing together the fitting and an insert via threads. A system includes a mold configured to form the substrate. The method also includes inserting a component into an opening of the fitting. Part of the component is disposed outside of the opening of the fitting, and the component is utilized to define the at least one channel within the substrate. The method further includes molding at least one material to the component and the insert to form the substrate. Furthermore, the method includes removing the fitting from the insert while the insert remains molded to the substrate.

Abstract: A method of bonding a second object to a first object includes: providing the first object having a thermoplastic liquefiable material in a solid state; providing the second object having a surface portion that has a coupling structure with an undercut, so that the second object is capable of making a positive-fit connection with the first object; pressing the second object against the first object with a tool that is in physical contact with a coupling-in structure of the second object while mechanical vibrations are coupled into the tool; continuing to press and couple vibrations into the tool until a flow portion of the thermoplastic material of the first object is liquefied and flows into the coupling structures of the second object; and letting the thermoplastic material re-solidify to yield a positive-fit connection between the first and second objects by the re-solidified flow portion interpenetrating the coupling structures.

Abstract: A metal casting method and a plastic injection molding method in which an insert is molded in molten material such that no molten material enters the interior of the insert. The usage of a wire thread insert as insert has the advantage that for example in an aluminum cast part thread holes can be produced already as part of the casting process. For this purpose, the casting mold, the insert, as well as the casting method are described.

Abstract: Composite fasteners have a high fraction of discontinuous, randomly oriented reinforcing fibers. A charge of thermoplastic fiber flakes are heated to melting temperature within a reservoir, flowed into multiple mold cavities and compression molded. The molded fasteners have high strength, exhibit quasi-isotropic properties and may be produced in high volume.
