A plastic repair welder (also called hot stapler, bumper welder, or metal insert welder ) is a power tool designed to repair thermoplastic plastic parts by inserting heated metal staples. [1] It is widely used in body shops, plastics manufacturing and repair industries, as well as in domestic applications to restore damaged components, replacing hot air welding or adhesives or even ultrasonic welding.

Operating principle

The device works by heating metal staples (usually made of stainless steel or corrosion-resistant alloys) until they reach a controlled temperature (between 200°C and 500°C, depending on the model). These staples are inserted perpendicular to the fractured area of the plastic. a bumper or fender, partially melting the surrounding material. When cooled, the staple becomes embedded in the plastic, creating internal structural reinforcement. The surface can then be polished and treated with putties or paints to restore its original appearance. [3]

History and development

The technique emerged in the 1990s as an alternative to traditional hot air welding or adhesive methods. Its popularity increased with the massive use of plastics in the automotive industry, where bumpers ceased to be metal. Brands such as Uretech or Steinel were pioneers in marketing professional tools. [4]
