Trust thanks to quality and reliable service – this is the heart of window manufacturer dtH Tiemann’s corporate philosophy. The company’s PVC and aluminum windows and doors have satisfied the highest demands for design, comfort, and security for decades. But that’s not enough: we use a continuous EDP system in production, and also for installation and our trade partners.
The company produces nearly 700 windows units daily on state-of-the-art EDP-controlled production systems. 400 of these are produced in Hille, and 300 in Herzberg, Brandenburg. In addition, there are PVC and aluminum doors, liftand- tip doors, and insect screens. All products are delivered exclusively to selected dealers.
Top quality for its partners is both a demand and a requirement for dtH Tiemann: this also applies for the suppliers, system providers, and technology partners with whom the company maintains a trusting relationship.
And here, dtH Tiemann is convinced that it works with the best in the industry. Production according to the guidelines of the ift Rosenheim and systematic internal quality management underscore the high demands posed of the end product.
Growth thanks to quality
Customers honor the concept: in five years, sales have grown constantly, forming the basis for investments in state-of-the-art production technology and innovative products.
Looking back to the year 1990, the company could no longer fulfill market demand with its capacities in Hille, so it had to increase its production capacities significantly. A second plant, 2,700 m2, was established in Herzberg. At the same time, Dirk Tiemann assumed responsibility for the company as the second-generation Managing Director.
Increasing competition drove dtH Tiemann to differentiate itself more on the market. Cost leadership was and is not the goal of the east Westphalian family-owned company.
The greatest delivery reliability, constant expansion of services, and consistent maintenance of its dealer network proved to be a better recipe. In 2005, the decision was made to introduce A+W Cantor corporate software, which maps all corporate processes, from entry of the element at dtH Tiemann trading partners to installation at the end customer.
Gerhard Vauth, Director of Purchasing and IT, “A+W Cantor is the only industry solution that meets all of our requirements, e. g. for materials management, delivery planning, and last but not least a continuous CIM* solution.” The continuity is demonstrated by the fact that we have more than 40 monitors in our operations with this CIM Solution.
Intelligent process control
The window and door products are made on state-of-the-art production systems – this is evident along all of the window production lines. This is where the current technology of leading window machine manufacturers combines the greatest reliability and production quality with the fastest throughput times.
This starts with software-controlled transport lines and buffer systems in the various production areas. Only in a networked system like this can the production technology of processing centers in both locations be used with the greatest efficiency on through to packing and dispatch.
The A+W Cantor production control ensures that each element is directed purposefully to the correct buffer position – even if, for example, sashes and blind frames are welded alternately on the same line or remakes with the highest priority “overtake” the pre-planned production batches.
Such flows show how IT-controlled processes result in concrete service advantages for customers. Gerhard Vauth, “Our production is very well-organized. With its integrated concept, A+W Cantor helps us make our high demands for customer service, reliability, and delivery reliability a reality.”
Computer Integrated Manufacture – Integrated computer application for production control
Each action creates value
Monitors and scanners have replaced stacks of paper and files. At manual workstations, the dtH Tiemann employees obtain true to scale sketches and production drawings on the A+W Cantor CIM screen with a click of the mouse.
Elements are identified, registered, and reported ready with bar code readings: here the label is the most important bearer of information.
“Paperless production describes just one aspect of our intelligent production,” says Vauth. “The most important thing for us is that every employee action should create value – unproductive activities such as searching and tracing no longer exist.”
The CIM network is seamlessly connected to the A+W Cantor ERP system, the commercial-administrative part of this comprehensive solution. Information such as control instructions for the production machines and status reports for order processing are exchanged in real time – the user never notices what kind of database-based solution this lightning-fast exchange of information this allows.
The software decides the production location
The integrated software solution also controls logistics between the two plants. Orders are entered completely, both commercially and technically, in either Hille or Herzberg. The capacities of each production location for the elements are checked. Production data and dates are forwarded automatically to the production location and to the CIM system.
In the door inserts sector, dtH Tiemann works closely with Rodenberg. Its online configurator, which is integrated into A+W Cantor order entry, offers many design possibilities and dtH Tiemann does not have to create its own master data. The trade partners can work comfortably within the usual order entry.
Another advantage: all door configurations entered at this dtH Tiemann partner have – as do windows – been subjected to a complete restriction check, so they are technically and statically feasible. Technical changes to the order and inefficient consultations are no longer required.
the A+W Cantor dealer program
One of the most important services that dtH Tiemann provides its trade and installation partners is the dealer program, which essentially corresponds to the commercial part of the A+W Cantor ERP system. Here, the dealer is always working with current data.
The sales partner’s calculation is transparent and traceable for the end customer. The so-called transfer file is released by the dealer, the order transmitted to dtH Tiemann via e-mail, and then it is put back into the ERP software.
The order is then confirmed immediately with the actual delivery date and released to production: we have a continuous EDP system that works across company boundaries.
Now the east Westphalians want to add another gear: currently, the IT team makes the complete online connection for all trade partners.
In an additional step, dtH Tiemann will also make the A+W iQuote Webshop available to dealers. “We believe that intuitive operation directly in a browser will appeal precisely to smaller, less EDP-capable dealers for whom the dealer program appears too complicated,” says Vauth about the company’s insight into the production procedure.
