Parts-Service & Consulting


Welcome to

TROUVAIN Parts-Service & Consulting

With more than 25 years of professional experience, I have acquired established expertise and very good knowledge of the industry. I am familiar with the daily challenges of working with suppliers.

"Anyone can do standard... – we can do much more:
complex precision spare parts and systems!
... and we are personally available for you!"


We offer:

  • Precision spare parts for the plastics and recycling industry
  • Personal availability with high reliability
  • Uncomplicated, fast and unbureaucratic action
  • Responding to customer needs and developing, manufacturing, and delivering according to customer specifications
  • Statements such as "We do not have", "Is not standard", "Only minimum order quantities" or "Product is too old" are foreign to us.
