Charge heating method and systems for induction molding
Abstract:
A method and system for heating a material includes an induction coil, a susceptor providing a receptacle, where the receptacle is configured to receive the material, and at least one nozzle for ejecting a heated gas onto and/or into the material. During the method, the susceptor is heated by the induction coil, and thermal energy from the susceptor can be transferred to the material. In addition to being heated by heat from the susceptor, the material is also heated by the heated gas, thereby increasing a heating rate of the material to rapidly heat the material to a processing temperature. The system can include other components such as a gas source, at least one conduit that channels gas from the gas source to the at least one nozzle, and a heat source that heats the gas prior to ejecting the gas from the at least one nozzle.
