Basic operating principles: 
this machine is a high frequency device, whose self-exited oscillator of the electron tube can produce high frequency electromagnetic field. and the plastic to be processed is in the high frequency electromagnetic field between the upper and low electrode. When its interior molecules are polarized and produce heat automatically by mutual movement and friction, it will be welded with the pressure of the die.
Features:
1. Anti-spark electric system
When the spark occurring, the high sensitiveness spark electric system will cut the high frequency power immediately to protect the mould and material.
2. Jamming Prevention Device
Equipped with high frequency stabilizer and magnetic leakage suppressor, this device can prevent the leakage of electromagnetic radiation to avoid other electrical instruments jamming such as televisions and radios, etc.
3. Safety Device
When the current over its limit, the overload relay works automatically to protect the oscillation tubes and rectifier. the frequency deviation caused by mistake is avoided.
4.the Special Mechanical Structure
with a excellent design and structure, the machine can works precisely and intensively.
5.Easy Tuning and Special Protection Circuit
the selectable output power can ensure the stable quality of the product. while the welding process, it could largely reduce the heating time.
6.Pneumatic Pressure Device
It is provided pneumatic pressurizing device, which can adjust the pressure in the practical situation, greatly decrease the operation difficulty and impaction equipments, changing the controlling method may modify the high-frequency process technology.
