Plastic instead of steel – What are the difficulties and opportunities?

The design flexibility, reduced noise, ability to operate without lubrication and corrosion-resistance are only some of the economic advantages of plastic gears. Nevertheless it is important to be familiar with the limitations of plastic gears relative to metal gears. Design and User Experience are key issues in the Industry, which faces many challenges, producing plastic gears with features required customer, ensuring that the performance stays as good as using metal gears. Listen during our international conference to topics such as:

  • Endurance, Strength and Calculation
  • Limit and Chances of Shape and Form
  • Tribology and Efficiency
  • Typical and Future Materials
  • NVH and Dynamics
