Method for small scale forming of hardenable materials of organic origin

A method for mixing of at least two different synthetic resinous materials, which comprises the following steps:

• (a) providing a predetermined volume of gas in a first gas reservoir and in a second gas reservoir at predetermined pressures of between about 30 atm. and 100 atm.,
• (b) providing a predetermined quantity of up to about 100 cm.sup.3, or gm, of a first material in a first material reservoir and a second material in a second material reservoir, said first and second material reservoirs each having a material storage inlet and a material storage outlet;
• said first and second storage inlets being in communication with first and second discharge means, said first and second discharge means each comprising a respective first and second discharge line and a respective first and second pressure transducer, the discharge lines each having a sufficiently narrow inner diameter such that each quantity of the first and second materials, when propelled by the gas under pressure, moves in a plug flow;
• (c) introducing into each of the first and second material reservoirs the predetermined volume of the gas at the predetermined gas pressures which are sufficient to propel the quantities of the first and second materials in plug flow and to achieve turbulent flow prior to a shaping means;
• (d) propelling the plugs of the first and second turbulent flowing materials through the discharge lines at a generally directly opposite angle to cause an overlapping contact between the materials in a mixing head;
• (e) measuring the time and duration of the propelled plugs of the first and second turbulent flowing materials in the discharge lines by using the first and second pressure transducers, respectively;
• (f) adjusting the gas pressure in the first and second gas reservoirs such that the materials are capable of being propelled at a velocity effective to cause overlapping contact between the materials;
• and
• (g) repeating steps (a)-(d) after adjusting the gas pressure.
