Abstract

Spin casting is the technological process to produce metal, plastic and wax parts quickly from an existing master model. It is especially suitable for the manufacture of die casting parts since the manufacture of dies is normally very time-consuming and expensive. The paper deals with the influence of mould rotation speed and clamping pressure during spin casting into silicon moulds on dimensional accuracy of zinc alloy castings. The rotation speed was in range 200 ÷ 600 rpm. Clamping pressure was in range from 276 to 379,5 kPa. The results of experiments are curves of rotation speed and clamping pressure dependence on dimensional accuracy of castings.
