PVC EVA Coated Fabric Welder HF Sealer Suspended Type High Frequency Welding Equipment
01: Application
PVC EVA Coated Fabric Welder HF Sealer Suspended Type High Frequency Welding Equipment has most common application in factories, it is used in the fabric industries to seal polyurethane and PVC coated fabrics, the process is also commonly used in different kinds of industries where polymer films need sealing, some of the common products that are sealed using HF/RF sealing include inflatable products, seat cushions, inflatable rafts, bladders of footballs, dust filters, sun visor/tops/doors,banners/signs, billboards, protective packages, truck covers, insects screen, stretch ceiling, awning, clear span outhouse/building, tents, tarps,tarpaulin, canvas, PVC,PU,TPU,EVA film, swimming pool, pool liners, containment booms, agriculture curtains, pergolas, pool covers, sheet protector and any other line seam sealed polymer products with membrane structure in construction
02: Advantages
PVC EVA Coated Fabric Welder HF Sealer Suspended Type High Frequency Welding Equipment is convenient in alignment during seam sealing, especially for large scale construction, the welding head is suspended, the user can align the welding position in any direction, the welding bar also can engrave decorative pattern in, text, logo or company name, embossed advertising or identifying codes print into the welded items are possible, by incorporating a cutting edge adjacent to the welding surface, the process can simultaneously weld and cut fabric, this is often called "tear-seal weld" because the cutting edge compresses the hot plastic sufficient to alloy the excess scrap fabric to be torn off, PVC EVA Coated Fabric Welder HF Sealer Suspended Type High Frequency Welding Equipment only focuses the heat at the welding target so that the surrounding fabric does not have to be super-heated and risk burning in order to achieve target temperature at the joint, with high frequency, heat is generated only when the field is energized, this allows for precision control over the amount of energy that the fabric sees over the entire cycle, when the fabric can remain under pressure without introducing more heat, it is possible to both instantly heat, weld and cool the fabric under compression, thus increasing the bonding strength, the welding force even is stronger that material itself, HF/RF-generated heat does not radiate off the electrode/bar like other heated surface used in welding, this prevents heat-degradation of the fabric abutting the weld, suspended high frequency welding equipment also can save foot-space because its welding head mounted at the top of working table

04: Salient Features
Hanging type: The handing type/suspended of welding head can process infinite long fabric in large sale production, which also convenient to align the welding position at any direction
Arc protective suppressor: when the spark occurring, the high sensitiveness anti-spark electric system will cut off the high frequency power immediately to protect the mould and fabric
Easy tuning and special protection circuit: the select-able output power can ensure the stable quality of the product while the welding process, it could largely reduce the heating time, the HF power at higher and lower point can preset in precision auto protective tuning
No high radiation: this suspended high frequency welding machine has good shielding device, all the parameters has passed the inspection of international safe standard
05: Notice
PVC EVA Coated Fabric Welder HF Sealer Suspended Type High Frequency Welding Equipment must focus on extremely important notice to avoid occurring spark during welding process, 1st factor is that to keep the fabric clean, and remove the dirty, contamination if any contained on the surface of welding area, because, the foreign particles, debris always come with fluctuation of electric resistance when HF energized under the electrode compressed onto the welding seam joints, 2nd factor of applying buffer, the reason for presence of a buffer is to facilitate usage of more HF/RF energy for sealing, when the sealing process is in progress, the fabric/polymer is melted for decreasing the thickness, the HF/RF energy continue to excite the molecules and like any other electrical field, it looks for the easiest way to complete the circuit easily, the closest ground being the bottom of the electrode/welding die, in the absence of buffer, once the fabric becomes thin enough, the HF/RF energy is likely to create a hole in the fabric/polymer, when a buffer is used, it provides electrical resistance to the HF/RF energy, thus diffusing it all through the surface of the electrode/bar/die, the 3rd factor is HF/RF output, select-able scale to limit highest and lower HF/RF energy in auto tuning, the users necessitate presetting limited range
PVC EVA Coated Fabric Welder HF Sealer Suspended Type High Frequency Welding Equipment 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
PVC EVA Coated Fabric Welder HF Sealer Suspended Type High Frequency Welding Equipment 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
PVC EVA Coated Fabric Welder HF Sealer Suspended Type High Frequency Welding Equipment is acceptable in construction of size, function, color, shielding. controlling system and auxiliary, we intend to provide a reliable and affordable seam joint bonding solution basing on robust structure, consistent and strong bonding strength, convenient operation, and precision control, if you cannot find your concerns, just share your proposals with our technical teams or sales representatives, our experts are always ready to work with together, submit their experienced suggestion for your approval after comparison prior to execution
