High Frequency Welding Machine
Welding is a sculptural process that joins materials, generally metals or thermoplastics, by fusing, it is different from lower temperature metal-joining techniques, for example, brazing and patching, which don't liquefy the base metal. Radio Frequency (RF) or High Frequency welding machine is used for fusing of materials by providing high frequency energy as an electromagnetic field (27.12 MHz) and weight to the material surfaces to be joined. A generator delivers the power. The device used to supply the energy is called an anode. The electricity causes the atoms inside the material to move, which creates heat energy that makes the material relax and subsequently intertwine. No heat from the outside is applied. It is rather created inside the material. The material mostly used for high frequency welding is PVC (polyvinyl chloride), also known as vinyl and PU (Polyurethane). The material can be thin or thick, reinforced or covered. It can likewise be plain, hued or designed. Four vital factors that influence the final result are weight, welding impact, cooling time and welding time. These parameters can be balanced and joined in various approaches to accomplish the ideal welding result for a particular material. The three major parts involved in the High Frequency Welding Machine are high frequency generator, welding machine, and electrode. The lower electrode is generally made of aluminum or iron and the upper electrode which is also known as high frequency mold is made according to the length, shape or range of the embossing designs.
High Frequency Welding Machine is usually simple to handle, produces a constrained debasement of the polymer even on thick layers, does not makes exhaust, requires moderate power and produces air, water and micro organisms proof welds. Welding parameters are time weight and Welding Power, (cooling and heating), while temperature is usually not directly controlled. Auxiliary items can likewise be utilized to tackle some welding issues. This kind of welding is utilized to combine polymer films used in different enterprises where a solid predictable watertight seal is required. In the fabric business, High Frequency welding machine is frequently used to weld polyurethane (PU) and PVC covered textures. Other materials which are generally welded utilizing this innovation are PEVA, EVA, Nylon, PET, and a few ABS plastics.
Tarpaulin Welding Machine
Tarpaulin Welding Machines are known for their extremely durable and reliable performance. This robust machine is used for center sealing process of a fabric as long as 12 feet and having 70 to 450 GSM. Tarpaulin Welding Machines are well innovated these days and equipped with LD sheet of above 500 gauges, also PVC coated. The machine has an opening at the top from which the fabric enters inside, fabric is sealed by the machine and eventually it falls at the bottom so that is easily folded and packed. The best thing about this machine is its centre cantilever which is made up of heavy steel structure to stand the electrical controls and other pressures such as from air blower. Tarpaulin Welding Machine has an excellent heating system as heated air is forced through the well formed nozzles situated at the nips. There are two different UN-winders provided into this machine, these UN-winders are located opposite to each other and are also equipped with a brake attachment shaft. Tarpaulin welding machine is supported by a DC motor and good quality gearbox and pulley.
