I need to form some plastic panels (windows) but don't know how/where to find an oven big enough to heat them in. I was wondering what temperture powder coat ovens run at, as I might be able to find a shop who could put my panels into their oven (I can clamp them to some old glass panels to give them the shape). The plastic should form at about 250-280 degrees.

Thanks - Greg

most pc ovens should be able to go to 450

First, it depends on the specific resin formulation. Most cure around 350 deg.

Second, production powdercoaters rarely use ovens anymore- especially on large items. They use UV arrays. You don't have to saturate the substrate with heat. You just have to melt the powder.

Find a body shop that has either portable UV arrays or an in-booth system. You'll need an IR thermometer to make sure you're not overheating or spot-heating.

Many plastics suppliers can do this for you.

Check with "REED Plastics" Rockville Md, they can form some very cool shapes - Rememeber when forming the plastic will become thinner at the bends - you have to over size to make up in areas that will be pulled thin

Gas or Electric Powder ovens have temp controllers and can be adjusted to any temp easily - Plastics can be very tempermental on temps - just when plastics become pliable they also loose strenght and want to slump or wrinkle - If you build a mold to support the entire part be carefull at you clamping points -

Suggestions - 1. Run a data logger on the oven to verify exact temp
2. Run a mock up sample first
