Forming prepainted metal

Numerous techniques can be used for forming of prepainted metals - in fact most techniques applicable to sheet metal can be used successfully.  Because the final surface finish is already applied, it is important for tools to be in good condition with no scratches, and sometimes it may be necessary to modify contact pressures to avoid scratching, but usually a good clean and polish is all that is required.  Since prepainted metal is itself self-lubricating, tools used for forming this material tend to stay clean and last longer.

The techniques used in forming a particular part will depend on the specifics of that part, but they include:

  • shearing
  • blanking
  • press braking
  • bending and folding
  • roll forming
  • deep drawing
  • spinning
