Product Description

Characteristics:
1. NL-5557 anti-spark vacuum tube protection device;
2. With double sides working station, accurate position and flexible action;
3. Easy operation, high working efficiency
4.Foot pedal switch.

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.

Application range:
High frequency welding machine for Shoes upper, trademark, Sticker, raincoat, Umbrella, leather bag, Hand bad, beach bag, Stationery, nameplate, Air-stuffing toy, waterbed, leather products and PVC products.

Remarks:
1. It can according your products to order the big power machine. 
2. This model has 5KW, 8KW, and 3 different dissigns for you to choose.
3. Customize is warmly welcome.
4. We can provide you mold and technical support.

Product details

Advantages:

1. The great advantage of HF welding is the speed of welding: the material is heated from the inside and fuses quickly, within few seconds.

2. In comparison with high frequency, in all other kinds of welding methods (with filaments, hot air or infrared radiation) the heat has to be added from the outside. It means the heat must first penetrate the material in order to make it plastic enough to form a weld. The main risk of this kind of treatment is burning the top layer of welded material.

3. In a high frequency field some materials generate more heat than others, and are therefore more suitable for HF welding. This has to do with the extent to which the molecules of the material allow themselves to vibrate as a result of the HF field.

4. This is known as the loss factor of the material. The greater the loss factor of the material, the easier it is to weld the material using high frequency equipment. Particularly easy to weld are thermoplastics, such as PVC and PU; these materials are specifically welded using high-frequency welding machines. PE and other hard plastics are much more difficult to weld with HF method.
