New Lehmann Group premises

After the symbolic groundbreaking ceremony in mid-December 2016, construction work for the new Lehmann Group premises in Minden-Dützen/Germany is well underway. The single-floor, 6,000 m² production hall is being built first. This first construction phase will be completed in July 2017 as planned. The tool manufacturing facility and Goldin Druckguss GmbH & Co.KG will then be the first to move from their previous sites into the new complex.

A 2,000 m² central administration building will be built as part of the second construction phase. The full potential for an environmentally sound and resource-efficient production facility will be fully exploited throughout the entire construction project.

Heat engineering

Along with the installation of a photovoltaic system, a combined heat and power unit (CHP) with exhaust gas heat exchanger will round off the resource-saving energy concept of the lock specialists from Minden, Germany. For further heat utilization, heat exchangers will be installed in order to be able to utilize the remaining residual heat from the exhaust gas flow. The residual heat produced by machinery will be diverted into the ground via probes, and stored there in order that it can be reused in winter for heating the halls via the probes. Thus, residual heat generated in production will not be wasted, rather it will be used for heating the production hall via thermal concrete core activation. As a convenient side effect, this system will also make it possible to cool the halls in the summer months. The installed buffer storage units will also supply the electroplating facility. Furthermore, they will supply hot water for the works canteen or for heating offices.

Electrical installations

All planning in terms of increasing efficiency and saving energy in the production processes is designed to achieve a significant reduction in consumption. Thanks to a regulated compressed air system with speed-controlled fans, only the amount of compressed air necessary will be generated. This will increase production safety, improve energy efficiency and save costs. The installation of a modern LED lighting system, coupled with energy-saving machinery, will reduce energy consumption. The electricity generated by the installed photovoltaic system will be used 100% in-house.


A further cornerstone for protecting the environment and climate at the new company premises will be the sequential integration of electric vehicles into the existing fleet of vehicles. This includes the installation of an electric charging point that will be available for use for customers, employees and for company-owned vehicles.

Expanding markets

Defining sustainability as an integral part of the company creates new opportunities for the marketing of engineering services, which are often followed by production orders, say corporate management. Tool-making, foundry, injection moulding and electroplating services have already been offered on the market by the company in the past. These areas will be grown further through the resolute implementation of resource-saving technologies, the infrastructural integration of the corporate divisions, realignment of logistical processes and, finally, through the pooling of key corporate areas of expertise.

At the same time, the company will be even more strongly perceived to be a reliable, future-oriented partner than previously, which not only benefits regular customers, but also turns the focus on peripheral markets around the subject of locks, say the managing partners Renate and Sönke Schlüter. The investment in the new premises underlines the long-term strategy of the company and is also seen as an investment in the training and further education of employees. The long-term relationship with customers, suppliers and employees is to be strengthened even further.

The entire construction project is planned to be completed at the end of 2019. Once the integration of the three Minden sites – Goldin Druckguss GmbH & Co. KG in Porta Westfalica, Germany, Martin Lehmann GmbH & Co. KG in Minden-Bölhorst/Germany and Lehmann Vertriebsgesellschaft mbH & Co. KG – is complete, approximately 200 employees will be based at the new premises.
