Improved dosing and control at Handtmann
Modernise to economise: StrikoWestofen combines “PneuCo” with flanged riser tube
The globally-positioned Handtmann Group operates 44 Westomat dosing furnaces at its headquarters in Biberach, Germany. Its extensive experience with light alloy dosing technology enabled the casting manufacturer to carry out a successful modernisation programme with the help of the StrikoWestofen specialist team. Together, the two partners modernised the tried and tested PneuCo system with a flanged riser tube. This modernisation project led to great improvements in dosing system availability and process stability.
Handtmann Group (Biberach) believes the three key factors to success are: pioneering technology, innovation and commitment to quality. The light metal casting expert was able to observe all three of these principles during the recent modernisation project. Over a 24 month period, StrikoWestofen carried out a comprehensive upgrade of 44 Westomat dosing furnaces. The switch to flanged riser tubes with pneumatic measurement of the liquid metal level - PneuCo system, and the installation of the ProDos3 control systems means the furnaces are now well equipped for the challenges ahead.
Small feature, astonishing result: the PneuCo system
Complete control with the ProDos 3 system
In addition to the PneuCo upgrade, Handtmann also decided to improve furnace control with the ProDos3 high precision control system for high pressure die casting. Holger Stephan, who manages the Service and Spare Parts division at StrikoWestofen, explains: "Our ProDos3 with integrated biscuit correction increases the dosing accuracy of the Westomat. In addition, pressure fluctuations can be compensated, and reproducibility improved using a number of different correction factors": The optional web server is another new feature that allows the integration of the ProDos3 control into the local company network. This means that all relevant information, e.g. the furnace pressure and performance data, can be accessed conveniently from your office.
The modernisation programme also included joint testing of new refractory replacement parts for Westomat. A clear reduction in downtime during refractory repairs to the furnace with similar quality results supports Handtmann's three principles. As a result, the product will be used in the future when repairs are carried out on the lining of dosing furnaces. Finally, a new StrikoWestofen heating station increases the level of occupational safety when handling hot ceramic components, and a special assembly bench has simplified the fitting of flanged riser tubes with PneuCo.
Stephan added: "We are extremely happy with the successful modernisation programme and are proud that we were able to meet the specific requirements of our customer in such a flexible and cooperative way".
