DEFINITION

Classification: 264/402

DIRECT APPLICATION OF ELECTRICAL OR WAVE ENERGY TO HEAT THE MOLD (E.G., ELECTROMAGNETIC WAVE, PARTICULATE, MAGNETIC, SONIC, ELECTROSTATIC ENERGY, ETC.):

(under the class definition) Processes wherein electrical, electromagnetic, particulate, magnetic, sonic, induction heat, or electrostatic energy is directly applied to a mold or molding apparatus to cause said mold to be heated.

(1) Note. Some examples of wave energy found in this subclass are electromagnetic, particulate, light, sonic, supersonic, ultrasonic, gamma rays, X-rays, and magnetic energy. Particulate energy includes charged particles and atomic emissions, such as alpha rays, beta rays, and neutrons.

(2) Note. Terms listed in the glossary are denoted by an asterisk.
