High Frequency Preheater (Semiconductor Envelopment Equipment) 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 tim
