High frequency preheater: Roller-electrode type
Renovation in preheating technique was materialized into these two models which use rotating roller electrodes attaining uniform heating with drastic time reduction and sufficient interference suppression.
Features
Uniform heating turns on the roller electrodes can be preheated uniformly by receiving concentrated high-frequency energy uniformly. Rapid high-temperature preheating. The roller-electrode preheaters, which carry out uniform heating within a short time in a concentrated highfrequency electric field, can minmize pre-curing of the material. Therefore, when compared with the conventional preheaters, they can preheat the material to a considerably higher temperatures allowing a drastic reduction of molding time.
