<P>PROBLEM TO BE SOLVED: To provide a micro through-hole forming device capable of easily and efficiently forming many micro through-holes in a pre-form of synthetic resin in a simple manner and in a short time, and manufacturing a micro through-hole formed product containing a flat plate having many micro through-holes and a peripheral edge flange provided at the outer periphery of the flat plate. <P>SOLUTION: A micro through-hole forming device 10 includes a supporting base 11, a back sheet 12 which is held on the supporting base 11 and has heat resistance, and an ultrasonic form block 30 which is disposed above the back sheet 12 and has many projections 31 at a lower part. The back sheet 12 supports a pre-form 20 of synthetic resin that contains a flat plate 21 and a peripheral edge flange 22 which is provided at the outer periphery of the flat plate 21 and has a wall thickness larger than that of the flat plate 21. An ultrasonic form block 30 is vertically movable and ultrasonic-vibrated in the vertical direction so that the flat plate 21 of the pre-form 20 is heated by vibration, thereby melting the flat plate 21 to form many micro through-holes 41. <P>COPYRIGHT: (C)2013,JPO&INPIT |
