Proposal of casting technology for cooper alloy castnig with regard to their quality and productivity of fininishing oprations
Herzán, Jiří ; Lána, Ivo (referee) ; Roučka, Jaromír (advisor)
This paper is created based on the real situation in Armatmetal s.r.o. Based on customer requirements and possible reduction of finishing operations at the end of production in the foundry. The foundry technology of gravity casting into sand molds is changed to gravity casting into metal mold. To change technology at Armatmetal s.r.o. two types of castings were selected. The "Kloub 55 s vidlicí" casting was selected by the customer to test the new technology. Casting "Klínová koncovka KN10" was chosen by Armatmetal s.r.o. because of the structural design of the casting and the high repeatability of production. Castings are the subject of the paper. The diploma thesis includes methods of solving the elimination of foundry defects occurring on a complicated casting " Kloub 55 s vidlicí". The main aim of the thesis is to assess the technical-economic contribution of the change of foundry technology of the casting " Klínová koncovka KN10". The paper also includes a complex comparison of the current and new technology production with related problems and their solutions.

Design of the tribometr frame by casting technology
Vítek, Petr ; Frýza, Josef (referee) ; Košťál, David (advisor)
This Bachelor´s Thesis presents an engineering design of cast frame for simulator of elastohydrodynamic contact. Original frame is folded from machined parts, which limits shaping and increases the cost of production. Through the analysis of the current state and applicable foundry technologies has been developed design for new cast frame. The output is accompanying report and drawing documentation. The accompanying report documents the prototype production process.
