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.
Our quality management
Since 1997 datec has been certified in accordance with ISO 9001 by Norske Veritas. The following definition was given to an element of quality management: “A guarantee for this solid work is early planning and comprehensive 100% final verification of the systems being supplied. The significance of this approach can be determined in that it is not possible to supply “off-the-peg” goods, specifically for compact control systems. They must be adapted to customer-specific circumstances. Early agreement and constant contact with customers ensures that the systems’ quality is satisfactory and avoids misunderstandings and costly modification work”.
The unique character comes from the differences between the various sand treatment processes in the world of foundries.
Simulation as a powerful quality management tool
When programming control systems, things can quickly become awkward as a result of programming without a safety net, as the system to be controlled is not readily available fully constructed on the doorstep. On-site programming is expensive and more protracted than in the software office. A comprehensive software simulation will help alleviate this awkwardness. A separate programme simulates inflows and outflows by representing the dynamic behaviour. It not only represents the time lag of the final position signal of a weighing door, but also the corresponding weighing signal. In this way, all signals, up to manual operation, are represented. This allows control programmes to be completed on a very timely basis with a low on-site programming requirement. In this way, systems can be commissioned quickly, particularly for PLC upgrades such as from S5 to S7.
