A static mixing method for running a material through an element having at least two irregular passageways. Irregular passageways have an inlet, an outlet and a continuously varying sectional configuration from inlet to outlet. The mixed materials have a fluidity and are fed by pressurization into the apparatus. The mixed materials are compacted and reshaped by the sectional configurations.

Static mixing method

A method of easily consecutively manufacturing a layered structure with the same or different kinds of materials superposed in a plurality of layers, is attained by a simple mechanical method. The layered structure manufacturing method is embodied by use of a shaping apparatus having a unique construction. The shaping apparatus includes a plurality of irregular passageways disposed in a side-by-side relationship in the same direction, wherein sectional configurations of the irregular passageways continuously vary from inlets thereof toward outlets, and the irregular passageways are superposed on each other at the outlets. An apparatus body as a principal portion of the shaping apparatus may be constructed by connecting a plurality of elements in series, which are internally formed with the irregular passageways. Materials to be shaped, which exhibit a fluidity or plasticity, are fed into the inlets of the irregular passageways in the shaping apparatus. The shaped materials thereby flow to the outlets while the sectional configurations thereof are consecutively varied and, during this process, get confluent and diverge while flowing inside the irregular passageways.
