Employees of Freudenberg Medical in the silicone tubing production area.
This is where the new Helix iMC sensor technology from Freudenberg comes into play. Freudenberg specialists in Kaiserslautern spent a year and a half developing the technology and have been using it on one of two production lines since April 2019. The unique innovation reduces waste and its environmental impact by more than 25 percent. It will now be rolled out step-by-step at all Freudenberg sites that produce tubing. In Kaiserslautern, it has already decreased non-recyclable cured silicone waste by around two tons. This equals over 1.5 tons of CO2. If the technology is adapted to other production lines and Freudenberg Medical sites, savings can be made around the globe.
Helix iMC uses a tomographic system with an emitter and four sensors. They record and document the tube’s shape during extrusion. An algorithm calculates a cross-section view using these measurements that an employee can monitor on a screen. In addition to visual monitoring, the system automatically reports any deviations that it detects, making a precise and continuous measurement of the inner diameter and wall thickness during the production process possible.
