High Performance Plastic Gears | VDI Conference

During our 3rd international Conference on High Performance Plastic Gears experts will talk about the potentials of plastic gears and in which cases they are a better choice than metal gears to transfer power and torque. Experts and professionals provide answers regarding their current state of the art, application and experiences with high performance plastic gears and give an outlook on what the future holds in store for us. In addition, two exclusive evening events invite to network and exchange knowledge. The conference is an accompanying event to the “International Conference on Gears 2019”.

Advances in polymers have created plastic gear solutions

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 by the customer, ensuring that the performance stays as good as using metal gears. 

Listen during our international conference to topics such as:

  • Potentials for NVH improvements using plastic gears
  • Novel tooth geometry and applications in various industries
  • High-performance polymers for gears
  • Analysis of thermo-elastohydrodynamic (TEHL) contacts of thermoplastic gears
  • Methods for simulation and calculation of plastic gears

One ticket, three conferences, three days excellent knowledge transfer

Our International Conference on High Performance Plastic Gears, the International Conference on Gears and the International Conference on Gear Production take place simultaneously. With your ticket of the International Conference on High Performance Plastic Gears you can listen to all presentations of all three conferences with a total of five tracks.

Network with your peers at two social evening event

All participants visit two exclusive evening events together. The evening receptions offer a good opportunity to meet and greet old and new business partners from the industry and science. Join us and experience unforgettable evenings in Munich.
