High Frequency Movable Plastic Canvas Welding Machine which has PLC human interface is suitable for large canvas sunshade or tents.
What is High Frequency Welding?
High Frequency Plastic Welding is to apply high-frequency electromagnetic fields in the form of energy to applications and as the same time, provide pressure to bond materials surface to weld them. Each machine requires a high frequency generator to provide a high frequency current, so-called Oscillation tank. The tool used to transfer high frequency to the material is called electrodes, that is, high frequency mold.
High frequency welding is using a high-frequency current to generate heat, liquidate (melt) the plastic material together with the pressure to weld the materials completely without external heating. In the average pressure after a period of time to cool so that the products cure, high frequency welding process is complete. The strength of the material is stronger than the original after high frequency welding.
There are four important elements may affect the result of High Frequency Welding, which is press, high frequency currency, processing time, cooling time. For the ideal welding result on special materials, these parameters can be adjusted or combined in different condition.
The most common thermoplastic High Frequency welding material is PVC and PU, both thickness or thin. High frequency welding can also apply these processing on materials with PVC and PU coating. However, the materials need to be test by High Frequency Machine to see if the processing meet desires.
