| Résumé : |
Automotive supplier Pollmann uses an injection molding process to physically foam glass fiber-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. |

- 4000 parts per shift
- Generator plus compressor system and buffer tank
- Payback period of about two years
- Figure : The housing for a doorlock system is manufactured by the MuCell
- Fig. 1 : The injectionmold has four cavities. Corresponding to a set of housings (two front and two rear doors) for each vehicle
- Fig. 2 : Inmatec nitrogen generator. The tank on the platform to the right is the product tank (150 l), into which the generated nitrogen is first introduced unde 6 bar. The second module on this platform is the compressor system. The large tank on the right is the buffer tank (500 l), which contains N2 at 25 bar from here, the pipeline leads to the injection molding machines |
