This paper presents the possibility of evaluating the 3D surface roughness of a raw die castings made from alloy AlSi9Cu3, group EN AB- 46000. Castings were produced on BUHLER H630-B die casting machine with various piston speed. The study was conducted on casting bracket for seatbacks office chair, whose surface do not require further machining to obtain adequate surface quality. In order to reduce the impact of possible surface mold roughness wear, the specimen has been taken from the places furthest away from the supply system. Evaluates of 3D surface roughness of specimens was performed on specialized software delivered with scanning electron microscope. After conducting a series of test on surface topography was evaluated roughness of raw castings produced with variable parameters of process control, such as piston speed during II Phase. It was found that the method used to measure 2D and 3D roughness parameters could be more practical in evaluating the quality of die castings, but it should be combined with the way their manufacturing and other destructive and non-destructive evaluation.
