Researchers from the Polytechnic University of Cartagena (UPCT) and the University of La Laguna have patented a microwave oven reduced hours or even days to just minutes, time, costs and risks of breakage in the smelting process mold.
The oven and the patented process are initially designed to scale ceramic molds used for creating artworks, but this technology "also has application in the field of micro-jewelry and could be transferred to all industries that perform processes foundry to manufacture parts, replacing autoclave systems, "explains Professor UPCT Juan Monzó Cabrera.
The system developed by these researchers mixing microwave absorbing materials with the mold, making the wax with which it forms part is provided to melt and expand without a short time.
Making it possible to save large amounts of time and energy expenditure required by other systems using electric or fuel furnaces.
"The cost reduction allows descerar works at a time while avoiding breaks in a process instead of lasting several hours is reduced to a few minutes," the researcher at the School of Telecommunications UPCT.
The research, which has been funded by the Ministry of Economy and Finance, has been led by Professor Juan Carlos Albaladejo Gonzalez, Faculty of Fine Arts at the University of La Laguna in cooperation with the Research Group of Electromagnetism and Matter UPCT.
This group Politécnica de Cartagena last year and devised an innovative microwaves, allowing separate compartments in cold food and cutlery and has been commercially exploited by a Dutch company.
Also in 2013 patented a mold for industrial microwave accelerating the polished marble.
