Annual external audits by SGS-TÜV Saar GmbH confirm the high level of our systematic quality management. We are currently certified according to the ISO 9001:2015 standard.
Curiosity is the basis of all innovations
In the economic world, stagnation means regression. Research and development helps counteract this – at SCHLEICH, it is one of our core pillars. And because innovations are only truly innovative when they offer practical benefits, collaboration with customers is paramount.
What transforms a mere idea into a true innovation in the economic sense is its practical and economic benefit, coupled with the constant question of where further improvements are possible.
SCHLEICH constantly embraces the challenge of developing new technologies. Our engineers and developers approach their work with curiosity, creativity, and enthusiasm. Research and development are conducted in collaboration with our customers. Ultimately, it is their specifications and goals that need to be implemented. And only through collaboration on an equal footing do technically sophisticated improvements and innovations emerge.
Innovation thrives with expertise. Over 70 years of experience, combined with the theoretical and practical competence of our employees, form the foundation for us being a valued development partner for our customers.

SCHLEICH is one of the most innovative companies in Germany
Since 2012, SCHLEICH has already been awarded the "TOP 100 Innovator" seal of approval five times for its innovation management.
The TOP 100 innovation competition is based on an independent, scientifically sound process and is not supported by companies with external interests or sponsors. Those who wish to become a TOP 100 innovator undergo a thorough selection process, which meticulously examines the development status of their innovation management. The analysis focuses on both the present and the future viability of a company. The evaluation is not based on individual innovations, but on innovation management as a whole.
To ensure all companies have equal opportunities, the award is granted in three size categories: up to 50 employees, 51 to 200 employees, and more than 200 employees.
In 2022, we once again prevailed in the "51 to 200 employees" category of the TOP 100 competition, which is unique throughout Germany. Through a rigorous scientific pre-selection process, we advanced to the expert jury round and received the coveted award for our company's innovation achievements.
With this, SCHLEICH has once again proven its position among the most innovative medium-sized companies in Germany.
