Forming Plastic with Hot Air
Versatile and Durable
Plastics such as PE, PP, and PVC, but also products manufactured using renewable materials, such as linoleum, are easy to form using hot air.
- Pipe forming: When processing plastic pipes, during plumber's metalwork, for example, the pipes are formed using hot air. The pipe is first heated and then shaped into the required form. Once it has cooled down, the pipe has its new shape. When two pipes are being connected, the larger opening (sleeve) is heated so that it can stretch and the other pipe section is then pushed in. Once the materials have cooled down, this produces a permanent, leaktight connection.
- When preparing for installation of thermoplastic membranes on roofs or in civil engineering applications, the plastic is formed at awkward points such that it becomes easier to process later on.
- During the installation of resilient flooring, hot air can be used to shape the material into the required form; raising material into corners or onto stairs, for example.
- Deep drawing/deburring: Hot air is used for forming in the packaging industry, the food and beverage industry, and injection molding. We recommend solutions from the industrial Process Heat product line for these application areas.
