PRODUCTION OF MICROMIXER USING UNCONVENTIONAL TECHNOLOGIES

TECHNOLOGIES FOR MICROPRODUCTION ARE BECOMING MORE DIVERSE AND PRECISE. THE NEED FOR SMALL PRODUCTS IS INCREASING AND THERE ARE MANY OPTIONS TO PRODUCE DEVICES WITH ACCEPTABLE PROPERTIES. APPROPRIATE CHOICE OF MATERIA LS AND PROCEDURES CAN BE BENEFICIAL BOTH FROM COST AND SPEED OF PRODUCTION POINT OF VIEW. IN THIS PAPER PROCESS CHAIN FOR PRODUCING MICROMIXER IS PRESENTED. TECHNOLOGIES USED ARE: WATER JET (WJ) AND ABRASIVE WATER JET (AWJ) CUTTING, DIE -SINKING ELECTRICAL DISCHARGE MACHINING (EDM) AND GRAVITY CASTING OF POLYDIMETHYLSILOXANE (PDMS). MAIN SOURCE OF ERROR AND DEVIATION WAS CUTTING WITH WJ, SINCE IT PRODUCED HIGH TAPER. AWJ WAS BETTER, BUT WIDTH OF CUT WAS NOT ACCEPTABLE FOR NARROW CUTS. OTHER TWO PROCESSES PER FORMED ADEQUATE TO MICROPRODUCTION STANDARDS, BUT CAN BE GREATLY IMPROVED AS WELL.
