II. What is HF welding ?

High frequency welding is the joining of material by supplying HF energy in the form of an electromagnetic field (27.12 MHz) and pressure to the material surfaces to be joined. A generator produces the energy. The tool used to supply the energy is called an electrode. The electrical energy causes the molecules within the material to start moving, which generates heat that causes the material to soften and thereby fuse together. No outside heat is applied. It is instead generated within the material. After cooling the welded surface under maintained pressure, the material is fused and a weld has been created. The weld seam can be at least as strong as the surrounding material – or even stronger.
Four important factors that affect the final weld result are pressure, welding effect, welding time and cooling time. These parameters can be adjusted and combined in different ways to achieve the optimal welding result for a specific material.
The material most commonly used with HF welding is PVC (polyvinyl chloride), sometimes called vinyl and PU (Polyurethane). The material can be thick or thin, reinforced or coated. It can also be plain, colored or patterned.
CONNIE customers manufacture a great variety of end products in these materials, such as truck and boat covers, tarps, tents, structures, pool liners, sunshades, billboards, inflatable products, liquid tanks, film screens, waterbeds, stretch ceilings, valve membranes and oil booms

III. Main Functions
1, Anti-spark protection
When spark occur, the high sensitiveness spark protects electric system to cut high frequency power immediately to protect mould and material.
2, Jamming prevention device
Shower Curtain Welding Machine equipped with frequency stabilizer and high frequency magnetic leakage suppressor, this device provide leakage of electron magnetic radiation to avoid jamming other electrical instruments such as television and radios etc.
3, Safety device
When the current exceeds its limit, the overload relay functions automatically to protect oscillation tubes and rectifier. Frequency deviation caused by misoperation is also prevented.
4, Easy tuning and special protection circuit
Shower Curtain Welding Machine has selectable output power ensured a stable quality of the products for it could reduce the heating time when joining is being carried out.
5, Easily adjustable tuner
Output power can be adjusted at the tuner according to electrode size and material thickness. In addition, other control devices and special electrical circuits have cut down required welding time considerably to raise the machine productivity.
6, Adjustment for the distance on the machine head
Adjust the distance on the Shower Curtain Welding Machine head if practical as the mould's size and height are different. Save working load while processing accuracy can reach to 98%.

IV. Application Range

For welding PVC or PU tarpaulin,also could

do space membrane structure,tent,sunshade film ,banner film ,advertising cloth ,computer printing cloth and curtain etc .with accurate positioning and smooth welding etc.

. Machine Working Principle

HF Welding relies on certain properties of the material being welded to cause the generation of heat in a rapidly alternating electric field, so called dielectric heating of the material to be welded.
This means that only certain materials can be welded using this technique. The dynamic electric field causes the molecules in polar thermoplastics to oscillate.
Depending on their geometry and dipole moment, these molecules may translate some of this oscillatory motion into thermal energy and cause heating of the material. A measure of this interaction is the loss factor, which is temperature and frequency dependent.
