What infrared lamps to use for powder coating




2007

I want to do some small scale powder coating and would like to use infrared heat lamps for the curing. I actually live and work in Saudi Arabia so many things we take for granted at home can't be purchased out here. Accordingly, the only lamps I've been able to find are 110v 250 or 300w screw in bulbs. Will these be suitable at all for powder coat curing? Is so, how many would I need to achieve up to 400 degrees F?

I hope someone can help,
Best Regards,
Wayne

Believe it or not, they all work on different frequencies and some of the powder reacts differently. How many, that depends on the mass of your part, air currents, wattage of the lamp, distance from the part and insulation of the box.

Hi I have built several infrared powdercoat plants.
I found the best way is too use the linear 500watt garden light.
get two 500-watt lamps and fittings and remove them from lamp case, and wire them in series this will now run the lamp at half its correct voltage and will mostly output IR.
about 300watts per pair off lamps.
the last plant I built ran at 30KW and was running at 8feet per minute.
these lamps must be around some where.

The "500W garden light" sounds like a great low-cost, low-tech method, especially because the ones sold expressly for powder-coating seem very pricey - but by "garden light," do you mean the typical cheap 500W halogen "work light" type fixtures? Sounds like you might mean these common halogen-lamp type (similar lamps in 150W, 300W as well) that are often sold as twin-head units on tripods for construction lighting, or as individual portable single-head units. If this is the type you mean, I assume you strip the fixture/s or rebuild them to eliminate any glass filters...maybe needs some kind of flex-head to allow repositioning for different objects to be coated?
