Import 20kw Hf Generator For Plywood Curving — Buy in wholesale FOB from Supplier in China

The 20kW HF Generator from Shijiazhuang Chancs Trade Co. Ltd. is an industrial high-frequency heating device designed for woodworking applications including plywood bending, glue curing, and timber drying. This generator operates by generating electromagnetic fields between electrodes using three-phase alternating current, with the HF frequency causing water and glue molecules in the material to polarize, rotate, and heat through friction-based dielectric heating. The unit offers selectable frequencies of 6.78MHz, 13.56MHz, and 27.12MHz, allowing operators to match the frequency to specific material characteristics and processing requirements. The model designation hf20-6-ii-ch indicates a 20kW output rating with the 6 indicating 6.78MHz primary frequency configuration.

The generator features a FU834FA or FU924FA radio tube as the core RF amplification component, with three-phase full-wave silicon rectification providing stable DC power to the RF stage. Input power requirement is 30kVA from a 380V 50Hz three-phase four-wire supply, with forced air cooling maintaining operational temperatures during continuous operation. The tuning mechanism uses variable capacitance for precise impedance matching between the generator and the applicator electrodes. Protection systems include overload protection, wind pressure protection (for cooling verification), door switch protection (interlocking for operator safety), and filament warm-up protection to extend tube life. The unit offers single or dual output configurations, allowing connection to one or two processing stations.

This HF generator serves plywood manufacturing facilities, furniture production lines, and wood processing workshops requiring rapid and uniform heating for bending and glue activation. The dielectric heating method provides advantages over conventional conductive heating by generating heat directly within the material rather than through surface conduction, resulting in faster processing times and more uniform heating throughout the workpiece. Trade considerations include verifying frequency selection matches the specific application, confirming applicator electrode compatibility, and arranging appropriate shipping for this 700kg industrial equipment. Importers should request complete specifications including output power stability, frequency tolerance, and application guidance for their specific plywood processing requirements.
