Product Inspection and Certification

Our products are constructed and developed in compliance with national and internationally valid norms and standards. Product norms (e.g., ISO, IEC or EN norms) are included just as much as application related standards and guidelines. 

Trust is good, but monitoring is better!
Every product undergoes a CE conformity assessment in accordance with Machinery Directives, Low Voltage Directives, EMC Directives and RoHS before the CE Declaration of Conformity or the CE Declaration of Incorporation is issued.

Supply Chain Management

Assembly of Tabletop zero series

We strive to provide our customers with high product availability. To achieve this goal, we use the latest IT applications for production planning and materials management.

Assemblies are predominantly procured from Switzerland and its neighboring countries. The quality of purchased parts is ensured thanks to careful selection of suppliers and periodic on-site audits.

The value-added chain at Leister Technologies AG builds upon a high degree of vertical integration whereby key assemblies – which are the basis of the Leister quality standard – are manufactured in-house. System and processing technologies, optical designs and construction and production of customized clamping concepts belong to the core competencies of the Laser Plastic Welding business unit.
