一、High frequency waves are also called high frequency machines 

High-frequency and ultrasonic waves are two different concepts, and high-frequency waves are electromagnetic waves that are greater than 100KHZ, and ultrasonic waves are frequencies over 20 kilohertz. High frequency welding principle, the principle and ultrasonic welding is also different, high frequency is the use of high frequency electromagnetic field internal fierce collision with each other between the molecules of material high temperature to achieve the purpose of welding and welding, which is generated by using the principle of friction heating to produce large amounts of heat to achieve the purpose of welding and welding. High frequency application field widely, so there are high frequency plastic welding machine, high frequency skin plastic blowing machine, high frequency synchronization fusing machine, high weeks twist boxes indentation machine, high frequency metal casting machine, high frequency heating machine, etc. 

二、The composition of high cycle equipment 

By the high frequency oscillator and electric heating mechanism of two main parts, the high frequency oscillator using resonant cavity oscillation circuit, oscillation frequency comply with international and is superior to the national standard, generally using 27.12 MHZ and 40.16 MHZ and 13.56 MHZ. 

三、High-frequency waves are classified according to different USES and heating purposes: 

1、High week wave plastic welding machine 

It is suitable for plastic and paper plastic welding, such as double-sided plastic packaging, plastic paper card packaging, soft rubber molding and processing. 

2、High week wave preheater 

Suitable for pre-preheating and softening process of thermosetting moulding plastics, such as melamine tableware, semiconductor electronic component packaging industry. 

3、High week wave metal planting machine 

Suitable for preheating or induction welding of metal parts and plastic parts. 

Application: home appliance audio industry (metal trumpet and plastic welding), large or irregular plastic welding. 

4、High cycle induction heating machine for quenching, heating, annealing, welding ideal equipment. 

The welding area: diamond saw blade, lathe tool, saw blade welding. Eyeglasses and other heating and welding sites, can be heated various metal components, metal composite elements. Change induction coil according to the shape of the workpiece. 

5、High week boqu wood heating molding equipment 

Suitable for wood heating and drying, insect killing and glue forming. The furniture industry, musical instrument industry, such as wood splicing, laminated wood and solid wood bending and forming. 

6、High cycle dryer 

The industry is widely used in textile dyeing and printing, drying, drying, drying, sterilization, swelling and thawing. The application of high cycle drying technology in textile industry is the most advantageous and extensive .
