Latest Patents

One of his latest patents is a method for de-lubricating powder metal compacts. This innovative method involves introducing an oxidant mixed with a carrier gas into the pre-heating zone of a continuous furnace. The process effectively removes lubricant from powder metal compacts prior to sintering at high temperatures. By mixing a controlled amount of a gaseous oxidizing agent, such as moisture, carbon dioxide, or air, with a carrier gas, the method accelerates the removal of lubricant. This is achieved by decomposing lubricant vapors into smaller and more volatile hydrocarbons. The result is sintered components with surfaces that are nearly soot- and residue-free, possessing the desired physical properties. Additionally, this method prolongs the life of furnace components, including muffles and belts, while reducing downtime, maintenance, and operating costs.
