ElectromagneticInduction heater, and other heating elements, e.g. ceramic heater, cast aluminum heater, mica heater, etc. 1. Saving production cost It can save 30% to 80% energy compared with traditional resistance heaters. Plus, it can save the energy used to cool down work environment. 2. Improving plastic product quality It can better control the temperature. The heating on barrel surface is more even. The cooling is faster if with air coolers. Thus, the quality of melted plastic granules is improved. 3. Increasing plastic product quantity It has faster heat response. The pre-heating time is shortened by 1/3. Thus the production rate is increased. 4. Improving work environmentIt produces less heat dissipation, and thus leads to a lower temperature on the heater sheath. So the heater cover is touchable, unlike traditional heaters. In addition, it discharges less noise pollution and no dust at all. 5. Lengthening usage life As the heaters are running under only 100°C, the frequency of changing heaters is lower. In addition, the usage lives of barrels and screws are also longer. 6. Higher safety The failure rate is lower due to highly automated module control. Heater covers are touchable. And there is no currency leakage. 7. Easy installation and operation The V-type structure of the heater helps simplify and quicken the installation of induction heaters. The automated module control allows easy operation of the heaters. 8. Easy maintenance It uses multiple control units. So in case of malfunctioning, the plastic machines can keep running by only changing the problematic control board 1.
