Latest Patents

Lallement's latest patents showcase his innovative approach to casting processes. One of his notable inventions is a method of preheating a set of shell molds for lost-wax casting. This method involves individually charging shell molds into unit electric furnaces that have been preheated to an initial loading temperature. The process includes starting a predefined preheating cycle for each shell mold, which raises the temperature of the furnace in compliance with a predefined ramp up to a predetermined setpoint temperature. At the end of each preheating cycle, the shell mold is unloaded, and the process is repeated for another non-preheated shell mold.

Another significant patent is a process for manufacturing single-crystal seeds simultaneously with the casting of single-crystal parts. This process involves producing a wax pattern that includes a pattern for the nozzle, a pattern for the starter seed, and a pattern for a crude seed. The method includes forming a ceramic shell mold from the wax pattern, incorporating a starter seed into the mold, pouring metal into the mold, and directionally solidifying the metal from the starter seed. The resulting seeds have the same crystallographic structure as the nozzle, which is crucial for high-pressure turbine applications.
