One-day Seminar

Quality of Elastomer Products – From the Mixture to the Finished Part

About the Seminar

In this seminar, Timo Richter provides a well-founded overview of the complete manufacturing chain of technical elastomer parts. A special focus is placed on component quality and all relevant process steps that have a particularly critical effect on the quality of the final product.

In the course of the seminar, Timo Richter also discusses in detail the reasons for the particular complexity of elastomer processing and how processing companies deal with this. Finally, he highlights the main reasons for the comparatively high quality fluctuations most elastomer products are subject to.
