Machine Description

Tents Making PVC Welding Radio Frequency Seam Sealing Machine

01:Application and advantages

Tents Making PVC Welding Radio Frequency Seam Sealing Machine is process of dielectric sealing, suitable for welding, sealing or making PVC, PU, TPU Tarpaulin, canvas products, such as portable water tank, gas tank, oil containment boom, stretch ceiling, tents, truck covers, advertising banners, film screen, awning, canopy, curtain,tensile membrane structure, sunshade, inflatable dome, tailgate, pool liners,banners, advertising billboard,signs and many other flexible plastic products

Tents Making PVC Welding Radio Frequency Seam Sealing Machine also in a very safe, reliable technology that has been widely used for over decades, it is the process of fusing material together by applying radio frequency energy in the form of an electromagnetic field to the area to joined, a generator produces the energy, the tool used to supply the energy is called an electrode (or bar), the electrical energy causes the molecules within the polymer to cause molecular friction, which generators heat from interior, and soften and thereby fuse together under adjustable pressure within rated activating time and dwell time in final solidification

Tents Making PVC Welding Radio Frequency Seam Sealing Machine carries a sturdy bonding results, no outside head is applied because the heat is generated within the material, merely localized in the joining area, there are not adhesive or by-products involved in R.F welder, R.F welder uses a precise combination of time, pressure and R.F energy to form a stronger more uniform weld across the seal, this makes the weld seam as strong or stronger that the surrounding material, the resulting weld is also air/gas-tight, and water/liquid-proof

03: Maintenance proposal

In order to preserve the longevity of your Tents Making PVC Welding Radio Frequency Seam Sealing Machine, maintenance is key, when a R.F welder goes down, there can be serious ramifications such as halts in production leading to a loss in profit, this is why keepleader has created a checklist that outlines the preventative measures you can take on a daily to a yearly basis to ensure that your R.F welder is running smoothly, as a disclaimer,before any maintenance is carried out ensure that is in a safe condition, and that services are switched off and isolated, always short capacitors and components to earth before touching, never use wet or oil rags when cleaning H.F welder, especially for electronic components, instead use denatured alcohol, below you will find a tried and true outline for maintenance of Tents Making PVC Welding Radio Frequency Seam Sealing Machine

031: Daily Maintenance

0311: Wide the table down every morning

0312: keep the area around the H.F Welder clean from debris

0313: Inspect the tooling for damage, repair according to procedure

0314: Inspect buffer for damage, repair/replace buffer and table if damaged

0315: Inspect ground shield

0316: Drain the water cap if accumulated full

032: Monthly Maintenance

0321: Replace air filter

0322: Inspect the cooling system in the barrel of oscillation tube,repair if abnormal

0323: Inspect air pressure regulator for leaks

0324: Inspect water cup for cracks or damaged seals

0325: Check inside air control system for air leaks

033: Periodic Maintenance

0331: Level tool holder

0332: Parallel tool holder and platen

0333: Ensure all ground shields are in good shape

0334: Check for cracks or discoloration

034: Yearly Maintenance

0341: Remove all panels and clean inside of the H.F welder

0342: Inspect the ground shields and replace if damaged

0343: Inspect bar or platen air pressure regulator for leaks

0344: Inspect water cup for cracks or damaged seals

0345: Clean interior of generator cabinet

0346: Remove and clean oscillator valve

04: Minding Notice for getting a reliable and consistent sealing effect

041: Arc or spark only occurs due to an irregularity, such as the presence of foreign matter, material imperfections, over current and pressure applied, or improperly located material

042: R.F sealing can be made more efficient by controlling heat loss, the heat is generated in the plastic, therefore, the tooling actually sucks heat out of the material since the tooling temperature is below the melt temperature of the plastic (115~160 Celsius degree), heat losses can be minimized by warming the tooling to approximately (49~66 Celsius degree), or by insulating the tooling surface from the product witch a buffer, bother methods reduce the heat-sink effect of the tooling, while allowing for efficient cooling after the R.F is turned off

043: Tooling that is run at temperature higher than ambient needs to be leveled on the press at the temperature at which it will be run, the natural tendency of metal plates to expand when heated tends to warp platens at higher temperature, leveling adjustments are built into most R.F welder platens to address the expansion and avoid warping

044:R.F output can also be enhanced by increasing press pressure so that the material will bond before interface reaches the temperature needed for a full melt, but this parameter has the smallest effect when compared with exerted energy and melting time

05: Salient features
