    Abstract: Material is supplied to a mold by direct application of gas pressure to a liquid material. A method for the shaping of at least two different synthetic resinous materials by providing a predetermined quantity of up to about 100 cm.sup.3 of a first material in a first material reservoir and a second material in a second material reservoir, the first and second material reservoirs each being in communication with a discharge line having a sufficiently narrow inner diameter such that each reactive quantity may, when propelled by sufficient gas pressure, be propelled in plug flow and each discharge line being in communication with a mold; introducing into each of the first and second gas reservoirs a predetermined volume of a gas at predetermined gas pressures sufficient to propel each quantity of material as turbulently flowing plug into the mold.
