CZECH FOOTPRINTS
UNITHERM, s.r.o. UNITHERM, s.r.o. has been in foreign markets since 1991, when it became an important Czech company in the field of heating. In 1999 the company made a strategic decision to expand its business activities to include the construction of a foundry and an aluminium casting machining shop. UNITHERM, s.r.o. is predominantly an export company with customers in Germany, Switzerland, Italy, Sweden, Norway, the USA and Slovakia, and a supplier for important Czech firms. Its products include gearboxes, engines and pumps, insulator flanges, pistons, parts of wind power plants and covers and lids. The foundry uses two technologies – sand casting and casting into metal moulds. The mode
are used in grey cast-iron and steel foundries and in construction. Using them in the aluminium foundry made it necessary to considerably change the forming mixture regeneration technology. This foundry is an ecological variant of the widely used toxic, highly inflammable and carcinogenic furan mixtures, which this foundry, situated in a protected landscape area, is not allowed to use. This unique foundry, built on the basis of its own research and development, can form more complicated shapes while making it possible to produce larger sections with the minimum occurrence of casting flaws, because additional water is no longer part of the sand mixture. The complete line comprises continuous mixers, a compaction table, slewing cranes with endless rotation, a portal crane, smelting furnaces, a hammering grate and forming mixture regeneration. We are persuaded that aluminium, now already widely used, is a
of casting depends on the client´s requirements, the quantity required, complexity of the casting and, last but not least, quality requirements. The Engineering Department designs the castings and the casting equipment using the SOLIDWORKS 3D program, with the support of the MAGMASOFT(R) program, which verifies the correctness of the construction of the casting and the casting technology and, at the same time, predicts the occurrence of potential defects in the casting. The foundry has nearly 1 350 different types of castings in its portfolio. It has its own machining shop with CNC machining centres and lathes and offers clients the possibility of machining the castings. In 2014 the company built a completely new foundry on its premises, where the technology of mould and core production utilises the self-hardening binder system based on geopolymers. Mixtures based on these binders
metal that will play an increasingly greater role in the composition of components and will become indispensable in industrial production and technology. That is why we use the most up-to-date technologies in the manufacture of components, which are at the same time environmentally friendly, and why we invest in the development of the company for it to be able to provide all-round services, from drawing documentation to surface finishing and control, which are needed for the correct functioning of the product.
