Micropunched microholes potential for bioapplications

Abstract

Punching is the process of forcing a punch through the material and into a die to create a hole in the work piece, and the most popular method for fabricating holes for mass production. It is often an economic way of creating shaped holes in mass production. It also offers some attractive characteristics that are superior to those of other processes, for example, machining and chemical etching, considering such features as high production-rates, better material integrity, less waste, lower manufacturing costs, etc. Therefore, micropunching is a
