Dong Loi Equipment & Services Corporation, established in 2002 in Ho Chi Minh City with branches in Dong Nai and Ha Noi, is a leading provider of technical services, industrial, construction and mining equipment.
Transparent PVC plastic film (PVC Crystal, also known as PVC Clear) is made from flexible PVC bioplastics, is waterproof, windproof, prevents cold and retains heat well, and can be seen through without fading. obstructed by sight, keeping heat and air conditioning in production factory areas.
Transparent PVC transparent material (PVC Crystal, also known as PVC Clear) is often used to produce the following products due to its special properties:
Tent windows, quick roll-up windows
Transparent curtains to protect against wind and cold and as a connection between indoor and outdoor areas
Industrial door, Waterproof dry bag
Pergolas, Canopies
Booth
Stretch canvas and inflatable structures (inflatable tents, inflatable houses)
Bottom Line: Thanks to its weather resistance and transparency, PVC Crystal Clear is versatile, highly regarded and widely used. But there's a catch. Anyone wanting to weld the material faces different challenges due to its special properties: Because Crystal Clear PVC is not fiber-reinforced plastic, and tends to warp when boil. Therefore, it requires special attention when welding. Because it tends to form folds, wrinkles or ripples, warping when welding with PVC Tarpaulin Film (PVC Tarpaulin is a membrane with woven fibers reinforced with Fiber-reinforced plastic).
Advantages and disadvantages of welding with HF high-wave welding machine
- HF welding machine is especially suitable for straight seams and is easy to operate, easy to operate
However, the price is high, it is less suitable for curved fish, and also suffers from sagging due to overheating
Industrial welding machine SEAMTEK W-900 AT, SEAMTEK 900 AT - Effective solution for welding PVC, TPU, Polyester
Leister's SEAMTEK welder is the ideal solution for anyone who regularly welds transparent PVC curtains. Stationary welding machine, designed to weld even large and complex thermoplastic materials in an efficient, safe and visually appealing manner.
Leister sells SEAMTEK welding machines in two versions: SEAMTEK 900 AT with hot air and SEAMTEK W-900 AT with hot blade technology. The latter is the ideal tool for welding Transparent PVC Film (PVC Crystal)
Silent and fast welding, the SEAMTEK W-900 AT gives users a lot of freedom when working and is ideal for welding large, even three-dimensional objects. Ergonomic and safe, it allows welding without generating fumes or unpleasant odors. Thanks to PLC control, welding parameters can be easily and immediately adapted to individual requirements. Controlling the heating wedge is quick and easy, as is changing the rollers. This increases efficiency during use.
Another important point to enhance competitiveness is lower energy consumption. With the SEAMTEK W-900 AT, this is certainly low thanks to the split-second regulation of the heating wedge. Thanks to its higher efficiency and energy consumption, investing in this welding machine is worthwhile as the purchase cost is quickly amortized, depending on the frequency of use. Last but not least, Leister's SEAMTEK W-900 AT has a PLC interface, allowing it to be connected to corporate IT systems and adapted to the requirements of Industry 4.0.
UNIPLAN 500 and VARIANT T1 - solutions for irregular applications
PVC Crystal Clear is commonly used in manufacturing environments where mainly straight seams are required and the objects to be welded are not too large, for example to weld windows for pergolas and patios or industrial doors. Sometimes this work is not part of the company's day-to-day operations, but is offered as an addition to the product range. In such cases, the investment in an HF welder may be too high. The purchase of SEAMTEK may also raise concerns about the amortization period of the costs incurred.
In this case, Leister's wide range offers more cost-effective alternatives: The two automatic welding machines UNIPLAN 500 and VARIANT T1 are perfect for processing canvases and technical fabrics. And they weld Crystal Clear PVC with perfect results, both aesthetically and functionally.
UNIPLAN 500 automatic welding machine
The Leister UNIPLAN 500 automatic welding machine is ideal for welding truck tarpaulins, sun protection, booths, tension structures and banners. The robustness and reliability of the UNIPLAN 500 ensures high and continuous performance.
The automatic welding machine has a modern electronic control system that allows quick setting of welding parameters. When welding a specialty material such as Crystal Clear PVC, it is important so that the user can make the necessary adjustments to achieve the desired result.
Variant T1 automatic welding machine
VARIANT T1 is the top model among Leister's automatic welding machines. Designed for overlap welding, it allows fast welding with maximum productivity and very precise results

How to Check whether HDPE Membrane Welds are Passable or Not? with Dual welding, automatic welding machine?
For a quality HDPE membrane weld, three factors are needed: Temperature, Speed, and Pressure. So after welding, how can we check whether the weld quality is satisfactory or not?
With the Examo 100 Leister hand tool, it is easy to check the peel resistance of HDPE, TPO, and PVC films quickly and profitably.
- If the weld does not peel off after driving, the weld is the opposite, you need to check the welding parameters of the machine.
In addition, it is necessary to check whether the quality of the materials is satisfactory, the site pressure, temperature, and ambient wind.
Overcoming the strictest standards of technical quality, the sales, technical and marketing team from the world`s leading technology company - LEISTER - Switzerland, from January 1, 2020, Dong Loi Company officially became become a GOLD PARTNER of LEISTER GROUP. Dong Loi is also the FIRST COMPANY TO ACHIEVE GOLDEN PARTNER LEVEL & ONLY in the field of providing solutions for plastic welding equipment & industrial heating equipment throughout Vietnam.
