We understand sand


What you should know about us: We, Dosier- und Automationstechnik GmbH (datec), are the only company in Europe that, for the past 25 years, has been supporting the modernisation of electrical equipment for your moulding sand treatment, from the planning as a manufacturer, to the delivery, and right through to the commissioning stage.

The company Dosier- und Automationstechnik GmbH (specialising in dosing and automation technology) was created from the company SMG (Steuerungsmessgeräte - measuring devices for control systems), which since 1948 has been drawing on its experience in manufacturing and use of moisture measurement devices for mineral bulk materials and capacitative fill level sensors. At the time, the predominant areas of application of the devices on offer were for the production of concrete, ceramic, glass and cereals as well as casting. In the 1980s microprocessor technology was implemented in the existing systems. This allowed the scope of tasks to be extended to include representation of moisture measurement, automatic water dosing through to overall control of dosing and mixing stations, including the power supply unit.


From our company headquarters in Braunschweig we have been marketing electrical equipment for sand treatment for foundries globally for around 25 years. As part of this work, we distinguish between instruments to measure for example moisture content, compressive strength or compactibility of the moulding sand, and electronic control systems, which ensure that sand treatment processes can take place in a safe and automated way. To complement our company’s range of services, we also programme visualisations which allow a comprehensive view of all plant components within the foundry.


The recipe for success of our activities is in the constant further development of our knowledge concerning the characteristics and processes involved with bulk material (moulding sand) – particularly in relation to water. The precise understanding of the spatial interplay between the bulk material and water allows us to manage treatment processes in sand treatment in a significantly more meaningful way. With our research projects (e.g. ZIM – Central Innovation Programme for SMEs), we are both ensuring that our knowledge is at the cutting edge and also laying the foundations for progress in sand treatment.


We provide reliable aftersales support to our customers through regular inspections. A team of twelve, predominantly consisting of mechanics, programmers and engineers, currently manages the aforementioned areas of work. Would you like to learn more about us? Contact us using our  contact form!

The basis of our many years of successful work in the foundries industry is our unique expertise in control technology. Only with this know-how can our water dosing and verification systems unlock maximum added value in your plant. To offer you an individual solution tailored to your needs, we begin the optimisation process when preparing the circuit diagram. In this way we ensure uncomplicated installation of supplementary plants and therefore save on structural expenditure.

Our commitment to the BDG (German Federal Association for the Foundry Industry) extends much further than simple membership. Sharing experience and cooperation is an important element of the work done in associations. We therefore take a leading role in various committees, such as the committee of experts for manufacturing technology, the working group for bentonite-bonded moulding materials, the working group for the evaluation of the capacities of testing equipment, the working group for process management, and on the Executive Board of the state association of Lower Saxony.

Our programmers are not only required to write good programmes. They must also put them into operation in practice on site. This may be expensive and involve effort, but it guarantees proximity to the actual application in the production. Experience and process knowledge are very directly imparted and guarantee well-thought-out concepts which are implemented through software. Programmers experience how their programmes run and how the user works with them.
