If you are trying to cure odly shaped parts you might run into trouble using a curing lamp. IR waves move in a straight line, this may leave curved or angled parts uncured or undercured. You might have to keep moving the lamp at different angles to properly cure a part. If you have any doubt at all, get behind it and aim it like a gun. Curing lamps work great "line of sight" but you might need to do things like make some brackets to aim it properly. Correct me if I'm wrong, but most powders allow for up to 100% overcure, so if you move it slowly chances are that you won't hurt the coating. Also trying some reflective materials like aluminum sheet (polished) in different shapes might help. You can pick it up at any Lowes or Home Depot, and it's easy to cut and bend to different shapes. There is no be all end all method for IR curing odly shaped parts...experimentation and evaluation is the key. Good luck to all who use IR to cure. If you come up with a successful method please share it with the rest of us.
