Riha Plastic Firmengebäude-Ansicht

Tradition and technology

Our family-run business is at home here in Biederach, on the edge of the Black Forest Elztal valley. Our close relationship with the region and its traditions is reflected in our SME company to just the same extent as dynamic progress in technology and management.

Our company stands out with personal, professional and flexible product support, development and production, with a team of around 40 experienced, committed and motivated employees. Here at Riha Plastic, they work together as a well established team which is geared to finding the solutions to your problems.

Since being founded as a one-man company in 1967, Riha Plastic GmbH has enjoyed on-going further growth and developed into a company which succeeded time and again in satisfying the very latest demands made of plastics moulding and plastics processing in injection moulding. This is safeguarded by keeping pace with state-of-the-art technologies and through the future- and growth-oriented alignment of the company.
