The aim of this thesis was to optimise the amount of lubricating substance used in the production of Mercedes Benz (P661) and Bayrisches Motoren Werk (P672) steering cases.
To ensure this, the two forms of mould cooling,
(i) inner mould cooling (using Farolin U as cooling agent) and
(ii) surface mould cooling (using Graco CP506 as lubricating substance) were investigated.
For the production of these steering cases, the Bühler SC 120 and the Idra 120 high pressure (i.e. 1200 bars) “die” casting machines were used.
After discussion with the contractors, the pre-study of the production process and the literature research, experiments were carried out on the machines under investigation.
As a result, room for quality improvement (technical changes, personal development) and lubricating substance optimisation possibilities were obvious.
To reach these conclusions, special capitals were considered and thoroughly evaluated.
