Ultrasonically driven molten resin bulge for the formation of metal micro-structures in laminated die cavity

Abstract: This paper proposes the use of ultrasonic bulgeforming process to fabricate T2 copper foil micro-structures. This approach involves the ultrasonic plasticization of powder in a laminated die cavity and the subsequent formation of a molten resin bulge. The laminated die is fabricated by microdouble-staged laminated object manufacturing and is then used as a concave micro-cavity. This technique uses ultrasonic melt polymer powder as a soft punch. Then, T2 copper foils are extruded into the concave die cavity. Co… Show more
