What is high frequency ? High frequency wave refers to the electromagnetic wave with frequency greater than 100Khz.
The commonly used high frequency is 27.12MHZ, but there is also a larger frequency 40.68MKZ,
We need to choose different frequencies according to product characteristics.
The principle of high frequency welding machine:
The principle of high frequency welding machine is to produce high frequency electromagnetic field by the electron tube oscillator. The welded sample is placed between the upper and lower electrodes with high frequency electromagnetic field, and the internal molecules are excited and move at high speed to rub against each other and melt, thus achieving the purpose of fusion or embossing under the pressure of the mold.
The driven mode of high frequency welding machine:
According to the driving mode of work can be divided into oil pressure type and pneumatic drive type;
Hydraulic high cycle machine, do not need air compressor,
Pneumatic drive high frequency machine, need to be equipped with air compressor.
Application of high frequency welding machine
Usually double head high frequency welding machine is suitable for soft PU or PVC, or cloth welding, indentation.
Things like shoe indentation logos, clothing logos. Also raincoat, rain sail, umbrella, leather bag, hand bag, stationery, name brand, blow toy, water bed, car seat cushion, sun visor, car door bolt, clocks, electronics, toys, blowing toys, locks, hardware, tools, trademarks and other special hard shell vacuum packaging.
The characteristics of high frequency welding machine;
The machine adopts high cycle loop optimization design and digital anti – interference circuit.
Toshiba oscillating tube made in Japan, which is stable and has reliable performance, long life.
The machine has high sensitivity spark protection system, effectively prevent this damage mold. Specially designed strong nose, maximum pressure is up to 400kgs, the welding trip can be adjusted, the product accuracy is up to 98%.
The upper part of the machine has a two cylinder system to make the pedal switch more portable. The operation of the staff is more relaxed and simple. The panels of the machine can be customized according to the size of the product to be welded. It is particularly necessary to remind that when the machine is working, hands should not be placed on the part of the mold, because when the machine is working, it will generate a lot of heat and easily burn hands. We can add safety grating if you need, but if you need to change the mold frequently, you can consider whether to add safety grating.
The great advantage of high frequency welding machine;
The spark protection system can be added to prevent ignition/discharge when the machine is working. Anyone who know the high-frequency machine principle knows that the tube oscillator generates a high-frequency electromagnetic field that causes the molecules inside the welded product to rub against each other to generate heat.So when high frequency wave is working, it is easy to produce discharge. And we can add this spark protection system to our machine. The discharge process is greatly reduced and can improve work efficiency and cost saving.
The machine operation is simple and easy, of course, if you buy the machine from us, we will adjust all the parameters before shipment and we will provide the operation video of the machine; If you are interested in it, please feel free to leave a message to us.
