Description of the invention (1 0) '~~~-The heated mixture enters a substantially homogeneous composite material. The composite ingredients are cooled to a temperature below the softening point of the thermoplastic adhesive, and • extruded from the mold. A key challenge is the technology for making extruded agglomerates, which includes semi-solid mixture particles and thermoplastic binders, flowing along an extruder and passing through a model. According to the method of the present invention, vibration energy is applied to the extruder and / or mold during manufacturing, increasing the flow of the particulate binder mixture through the extruder and mold. This vibration energy may be applied to an extruder and / or a piezoelectric dielectric device modeled according to techniques well known in the art. Increasing the optimum frequency and amplitude of the mixture flow must vary depending on each device design, manufacturing speed, particle size, binder selection, and manufacturing conditions (such as temperature and pressure). In addition, the most appropriate frequency and amplitude may change over time. Next, a computer-controlled producer was proposed to use the function built in which the feedback L οp was continuously optimized to set the frequency and amplitude model to time. These models change continuously along the length of the extruder and / or different locations of the model, and the frequency range includes subsonic, sonic, and / or ultrasonic vibrations. In this simplest form, the co-extruded agglomerate component pack of the present invention contains a porous first agglomerate and a second agglomerate, a specific example of which is illustrated in Figure 1.
