Car Tent Making Truck Cover Sealing High Frequency Vinyl Tarps Welding Machine

Car Tent Making Truck Cover Sealing High Frequency Vinyl Tarps Welding Machine is alive seam sealing practice via high frequency welding,also known as radio frequency welding, HF/RF welding or dielectric welding, is the process of fusing fabrics together by applying a rapidly alternating electric field applied between two bar in the joint area, HF welding only works with thermoplastics that have a high dielectric constant, a factor determined by the molecule’s geometry and dipole moment

Detailed Images

Car Tent Making Truck Cover Sealing High Frequency Vinyl Tarps Welding Machine is composed by HF generator, suspended welding head, and working table, HF generator transmit electrical current to high frequency alternating current of 27.12 megahertz, the polymer’s dipole molecules attempt to flip around to realign themselves to the new field orientation, this high-speed, relative movement causes inter-molecular friction, which creates heat, when the polymer reaches its glass transition temperature (melts), the pressure is applied at the joint by the high frequency electrode/bar until the fabric cools, during this process, the molecules from both fabrics intermingle and weld forms, the resulting weld can be as strong as the original fabric, molecules of fabric with low dielectric constant do not flip quickly or at all, consequently, they will not generate the required heat to form a weld, because of suspended/hanging welding head which avoid pneumatic driven standing frame to exert pressure during bonding to save the footprint, also is convenient to align the welding position at any direction 

Machine Uses

Car Tent Making Truck Cover Sealing High Frequency Vinyl Tarps Welding Machine is dielectric bar welder in molecular scaled seam sealing at the localized overload jointing interface, high frequency oscillation energy causes the temperature raised because of polymer resin molecular realignment in molecular movement under controlled pressure, when the High frequency halts, the melted thermal plastic takes quickly bonding after solidification, the welding principle of high fequency tech is definitely different with the conversional heat sealing process, the heat comes from interior to achieve a integrated sealing, the welding area is stronger that the material matrix, particularly, its bonding can bear the tearing and peeling force 

Overall Illustration

Car Tent Making Truck Cover Sealing High Frequency Vinyl Tarps Welding Machine exerts seam bonding process of instantly heating, melting, cooling in membrane structure construction, because of it creates air and liquid leak proof seals, tear and tear resistance with near-invisible seams, no wicking edges, and bonds that are as strong or stronger that the original fabric itself, the weldable material is polymer, which has high scale of dielectric constant, likely PVC, PU, TPU, EVA, ABS resin, PETG and APET
