I have an idea for something I would like to make and sell. I would like to be able to stamp or cut a fairly simple shape out of flexible plastic sheets, a bit like margarine tub plastic. What machine/device/tool would I need to be able to cut or stamp this shape (and yes, I know scissors would work, but I would like to be able to make quite a few)
A die cutter is one method. You can see simple versions at craft stores, it is like a cookie cutter with a sharpened edge. However, these cost a bit to have custom made, and they get dull. A CNC milling machine or Laser cutter could cut these out. A computer controlled engraving machine with the right bit could do this, too. The drawback is that it isn't incredibly fast, but you can change the shape at any time. CNC stands for Computer Numerical Control, what that means is that, like a Laser cutter you draw it on the computer. Then it uses a small spinning bit to cut out the plastic. Engraving machines are purpose-built CNC milling machines.
