Powder Coating

Part prep

  • Remove anything off the part that can’t handle 400°F
  • Part must be clean and degreased to prevent contamination of media
  • Sandblasting part first gives more grip for the powder to stick to and last longer
  • If the part has been sandblasted, bake the part in the oven at 180°F until the part reaches temp to degas and discharge part. Then allow to cool.
  • Tape anything off with high temp tape (PET, Kapton, Fiberglass) that you don’t want to be powered coated
  • Once the part is cleaned and discharged do not touch part with your hands

Powder coat gun prep

  • Make sure the gun is completely clean by blowing off any powder off and in the gun with air compressor
  • Completely clean out all powder from the powder bottle if using a different color
  • Only fill bottle 2in, NO MORE. The bottle needs air circulation to work properly.
  • Set gun to high voltage for most things for the first coat and use low voltage for very small parts or second coats
  • Set gun PSI to 3-5 PSI

Powder coating

  • Place part on rack or hang from rack using stainless steel hooks or wire
  • Connect ground wire to rack or wire
  • Check ground by moving powder coat gun close to part (1-2in) and push power button to see if there electricity aches to the part. If not adjust ground until you have a strong arch.
  • Hold button and spray powder 6-8in away in a circular motion around part until the part is evenly coated.
  • Start coating the parts that are deep and have 90deg angles (low voltage may help if it’s not sticking) then coat the rest at high voltage
  • Check evenness with led light
  • If air from the gun is blowing powder off part PSI is too high
  • If the powder is not sticking, the part may have not been cleaned well enough or not discharged enough
  • If you mess up or want to restart you can blow off the powder and restart

Baking part

  • Preheat oven to the temperature specified for the powder
  • Place part in the oven being careful not to knock off any powder from part
  • Measure the temp of the part until its at the specified temp for the powder being used (using IR thermometer)
  • Once the part has reached temp bake the part for the specified time for the powder being used
  • Carefully remove the part from the oven and allow it to cool down before handling
  • To add a second coat, coat part hot at 180°F with good ground and on low voltage and rebake
