A compression molding device, which can obtain a high compression molding force without lowering the efficiency of article production, and whose molding means has a long service life, is provided. In the compression molding device, a one-side mold assembly moving means (58) includes a toggle link mechanism including two links (62) and (64), and a toggle link mechanism operating means (60), while an opposite-side mold assembly moving means (108) includes a hydraulic cylinder mechanism. When a one-side mold assembly (16) and an opposite-side mold assembly (18) are to be brought from an open state into a closed state, the one-side mold assembly (16) is first moved to a nearly closed state by the one-side mold assembly moving means (58), and then the opposite-side mold assembly (18) is moved from the nearly closed state to the closed state by the opposite-side mold assembly moving means (108).

A method of imprinting a substrate (180), comprising affixing a flexible stamp (104) carrying an imprinting pattern (106) to a first carrier (102) comprising an array of apertures (112) which, by gas pressure, either pull the flexible stamp towards the first carrier or push it away; pushing it to a second carrier (170) carrying a substrate (180) with a resist layer (182), leaving a gap (190) for creating a controllable contact area between the flexible stamp and the substrate and space (196) between the first carrier and the flexible stamp; progressively pushing areas of the flexible stamp into the resist layer to imprint it; developing the resist layer; and progressively releasing the flexible stamp by applying suction through successive apertures whilst controlling the inward flow of gas to the space (196) through the apertures that are not yet under suction in order to maintain the space (196) there above ambient but below a predetermined maximum pressure.

What is presented is a mold support structure in a single dual injection molding machine for plastic part formation having at least two injection units. The mold support structure comprises at least one pair of platens located on opposite sides. Each pair of platens is separated by a plurality of reinforcement structures that provide support in the direction in which clamp and injection pressure is applied to the pair of platens during plastic part formation.
