Lacon Management

For more than 30 years, the Lacon Group has stood for the fulfilment of the special needs of the capital goods industry. With nearly 600 employees based at two sites, we develop, optimise, manufacture and repair electronic and electromechanical parts and modules. And in low and medium-sized quantities.

Since May 2019 HANNOVER Finanz Group has taken a 70% holding in the Lacon Group. Both companies developed a tailor-made participation model for growth and succession. The Lacon management intends to use the equity capital to drive further organic and inorganic growth.

As a medium-sized business, we are dependent on our seasoned and well-established team. We can offer the right combination of experience, professionalism and entrepreneurial enthusiasm.

Slaheddine Laroui, COO

A modern production system in a production unit run on the principles of a manufactory is a major challenge that we face each and every day. Highly diverse parts and products plus ultra-low production volumes require processes to be both flexible and stable. By defining standards, we create a goal-oriented organisational model that manifests itself in our factories in the form of uniform material flows, visualisations and processes. Quality, productivity, speed, flexibility and the reduction of any and all wastage constitute the strategic focus areas of our production system, with the goal of ensuring product and quality of supply at the level of world-class production.
