We are a family business manufacturing products made in the USA. Our products heat metal primarily for the automotive repair process. If an automotive part is bonded to metal, we can use flameless and contactless heat on the metal which melts the adhesive allowing the part to easily be removed without damage. We also heat frozen/rusted nuts and bolts. Instead of pulling out a torch, where collateral damage can occure, use the Mini-Ductor II to turn a 3/4" nut cherry red hot in 15 seconds. Our products are used in other industries including; aerospace, train, truck, ammunition, medical, farrier, blacksmith, oil, and manufacturing, just to name a few. Anywhere, where heat is required on a ferrous metal, our products heat.
