General Hot-Air Applications


The flexibility of hot air in plastic welding is practically limitless. Some of the most important applications include roof coverings, billboards and industrial fabrics, civil engineering, tunneling, landfills, plastic fabrication, resilient flooring, plus shrinking and vehicle repairs. Leister offers a variety of different heat guns and handheld plastic welding tools for each of these application areas. These tools differ in terms of their power, but also in their form: both bar- and pistol-shaped heat guns are available. The bar-shaped tools in turn come in versions operated through the use of an external fan and also those with an integrated blower.

Tools from Leister can be used for all imaginable welding techniques: overlap, pull, and spot welding, stitching, forming, heating, and shrinking to name but a few. A wide range of around 150 different nozzles helps the user in his day-to-day work.

  • Shrinking
    Special plastic hoses―known as shrink-on hoses, sleeves, tubes, capsules, tamper-evident seals, etc.―contract considerably when exposed to heat, thus protecting the products they envelop from mechanical damage or electrically insulating them. The most common way of effecting this process is to use hot air and Leister is the most experienced partner you will find anywhere in the world in this particular field.
  • Color Removal
    It is easier to remove paint or varnish with hot air than with chemicals. Hot air is the faster and more efficient method. This can be achieved with almost all Leister hand welding tools, but the E
  • hot-air hand tool is the ideal choice: on the one hand, it is very powerful, achieving a maximum hot-air temperature of 650°C (1,202°F); on the other hand, various wide slot nozzles and a special scraper nozzle are available for the ELECTRON ST. With this particular nozzle, the scraper is integrated directly into the nozzle
  • Molding
    lastics such as PE, PP, and PVC, but also products manufactured using renewable materials, such as linoleum, are easy to form using hot air.
  • Vehicle Repairs
    More and more vehicle components are being produced from plastic and hot air is perfectly-suited for repairing such parts. Hot air is easy and efficient to use, plus it is usually an inexpensive option when completing a repair, than purchasing and installing a replacement part.
