A three-dimensional cell growth containment article is described, which includes a molded body channelized by removal of sacrificial channelizing element(s) therefrom, so that the molded body contains one or more channel(s) therein, with a matrix material in at least one of such channel(s) that is supportive of three-dimensional cell growth in the matrix material. A method for making such articles is also described, in which a molded body is formed with one or more sacrificial channelizing element(s) therein, following which the sacrificial channelizing element(s) are removed. The three-dimensional cell growth containment articles of the present disclosure may be utilized in any applications in which there exists a need to reproducibly generate three-dimensional cellular structures, e.g., islet transplantation for diabetes treatment, transplantation of hormone secreting cells, cellular scaffolds for wound healing, and generation of tissue engineering structures to regain structural usefulness for orthopedic applications.

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.

A thermoplastic welding assembly and method for joining a plurality of thermoplastic support components to a thermoplastic component is provided. The thermoplastic welding assembly includes a frame, a plurality of heat sinks, and a plurality of individually actuatable pressurizers. The frame includes a plurality of welding slots.
