Nitrogen On Tap - Not from the Bottle

Physical Foaming Makes Plastic Parts Lighter and More Stable
Automotive supplier Pollmann uses an injection molding process to physically foam glassfiber-reinforced thermoplastics used in the production of electromechanical components that are installed in motor vehicles. The use of nitrogen as blowing agent makes the process more efficient and confers special properties on the components. An Inmatec generator in the Pollmann plant supplies nitrogen on demand and in the required amount.

Pollmann International GmbH, headquartered in Karlstein, Austria, is a globally active subcontractor that combines metal, plastic and electronics to create complex mechatronic components for the automotive industry. This family-owned company has proven expertise in the field of injection molding and is ahead of the curve when it comes to the production of housings for doorlock systems found, for example, in BMWs, Mercedes, and other marques. The production setup also features MuCell technology (supplier: Trexel GmbH): the lower shells of the doorlock housings are made on three 500 kN injection molding machines (manufacturer: Arburg GmbH + Co KG, Lossburg, Germany) from polybutylene terephthalate (PBT) with a 20% glass fiber content.
