Forming prepainted metal

Numerous techniques can be used for the forming of prepainted metals - in fact most techniques applicable to sheet metal can be used successfully. Because the prepainted product contains the final surface finish, it is important that the tools are in good condition with no scratches or damage on the tooling surfaces. It may be necessary to modify contact pressures to avoid scratching, but usually a good clean and polish of the tooling 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.

Techniques that are used to form prepainted metal include:

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