About Jiyuan High Frequency 2018-07-30T14:55:42+00:00

Shijiazhuang Development Zone Jiyuan Electric Co., Ltd. was founded in 1993, which is a private technology enterprise affiliated to Shijiazhuang Hi-Tech Industrial Development Zone in Hebei. In 1995, Jiyuan Electric was rated as “high-tech enterprise” by the Science and Technology Commission of Hebei Province, which has been re-approved in 2008. In 2002, the company passed the ISO9000 Quality System certification; in 2005, the company was elected as a director unit of the National Forestry Machinery Association of China. In 2009 we built a 33,000 m2 factory named Hebei Huas Jiyuan High Frequency Equipment Co., Ltd with capital 10 million RMB.

Jiyuan company is mainly engaged in the research, development and production of mechatronics high-frequency electric heating woodworking equipment. So far, they have developed more than 10 product series, and dozens of models and specifications, with more than a dozen of patents. The main products are high-frequency vacuum dryer, high frequency edge gluer, high frequency curved plywood press, high frequency frame assembly machine, high-frequency short cycle lamination press, high frequency cabinet door assembler, high-frequency generator, high frequency wood welder, etc. Thousands of furniture, wood, musical instruments manufacturing companies across the country are using Jiyuan products.
The company carries out cooperation with China Academy of Forestry, Nanjing Forestry University, Northeast Forestry University, Beijing Forestry University and other universities in all aspects, and maintains exchanges and cooperation with foreign technical experts in HF. After nearly 24 years of development, the company has established their leading position in the domestic industry.

RF/HF Heating Features

High Speed, Energy Saving

When RF (HF) starts, the molecules (such as molecules of water, glue or PVC) in the dielectric (insulator) material will be polarized in very short time and heated. RF (HF) power only heat polar molecules. It will not heat dielectric materials such as wood, rubber, glasses, etc. RF (HF) heating is 3 to 5 times faster than hot steam. It can save power and improve efficiency.

Uniform Heating

RF heating is dielectric heating. It forms electric field with positive and negative poles. RF power can penetrate materials deeply. The water or glue molecules in the material will be heated themselves by friction among molecules. In this way, material be heated from the core. That is more uniformly.

Wide Applications

RF heating can heat kinds of materials of different thicknesses, such as 2-3 mm veneer surface lamination, 1000mm thick engineered wood gluing. Different frequencies can meet different material requirements. 13.56 MHz is suitable for PVC heating and gluing. 27.12 MHz is good for fast dynamic water heating. 2 to 6.78 MHz is perfect solution for woodworking process, e.g. wood glue cure and wood drying.

Strong Controllability

RF heating is easy control and suitable for automatic production. Take RF board press gluing machine for example, RF can be equiped well with hydraulic system, electrical system. And all of them together can finish the whole procedures: feeding, pressing, heating, pressure holding, pressure releasing and material out. RF can also cooperate well with last procedures (e.g. wood finger joining) and next procedures (e.g. board sanding).

Insects Killing

By RF dryer, the machine can also kill insects, bacteria and worms when drying. You do not need chemical treatments for wood, grain, fruits, textile, biscuits, etc.

Environmental Friendly

RF heating does not need boilers. There is no dust, fog when drying. Jiyuan RF machines can also meet radiation standards of home and aboard. Also no harm to human beings.
