  • 1. WELCOME TO UNITHERM s.r.o. Germany Poland Jablonec nad Nisou Unitherm Prague Slovakia Austria1 U N I T H E R M
  • 2. The Company’s History and Development 1991, March 6th The Construction Department started the construction UNITHERM, s. r. o. was registered in Section C, of products based on the SOLID Works program. Insert 245 of the Commercial Register held at the The expansion of the aluminium alloy portfolio to Regional Court in Ústí nad Labem, include Al-Mg alloys. 1995 2009–2010 The company was awarded a diploma by the The cast blasting workplace was expanded to include Association of Danish Enterprises and the Medal of new machining equipment. His Majesty Henrik, the Prince of Denmark, for An investment was made in the renovation of the excellent services in promoting commercial relations Wenzel 3D coordinate measuring machine. between Denmark and the Czech Republic. A device was also purchased for ascertaining the 1999 hydrogen content in the molten metal – the DICHTE The company reached a strategic decision to expand Index. its business activities with an aluminium foundry. The Foundry – Machine Shop Division received a Initially the foundry was leased, but Unitherm, s.r.o. certificate according to the amended CSN EN ISO subsequently purchased it the following year. 9001:2009 standard and defended its previous CSN Unitherm, s.r.o. split into two divisions: the Energy EN ISO 14001:2005 certification. It also obtained the Division based in Arbesova Street, Jablonec n. N.

The foundry’s activities were the laser marking of casts and a barcode printer. expanded to include further types of cast processing, 2011 such as impregnation, heat processing, machining March 2011 – the 20th anniversary of Unitherm, s.r.o. and semi-assembly.

  • 4. Aluminium Alloys and Modifications Once the attested Al alloy has been received from the smelting works, an input control of the chemical composition is performed using a Spectrocast device. The achieved values are compared with the certificate from the smelting works and the EN 1706 standard. The values are stored. The inspected alloy is released for production. The Al alloy types areDevice for measuring the Dichte Index marked with internal colours in order to avoid any confusion. The Al alloy is melted in a gas smelt furnace (Morgan, Striko Vestofen). The smelted alloy is transferred to an electric resistance furnace, where it is refined using cleaning salts. The alloy is then modified (Na modification, Ti inoculation and Mg alloying). An FDU (Foundry Degassing Unit) degassing device by Foseco is used in order to guarantee the alloy’s low hydrogen content. The chemical composition is then checked again using the Spectrocast device. An Ideco thermo analyser is used to ascertain the progress of the solidification, the correct alloy modification and the primary grain size. The hydrogen content in the smelt is set using a MK Industrievertretungen GmbH MK 2200–LC device. The established alloy gasification values /the Dichte index/ are stored and presented to the client upon request.Spectrochemical analysis FDU alloy de-gasification / Alloy modification4 U N I T H E R M
