FACTORS AFFECTING FORMING
PRECISION IN PATTERNLESS
CASTING MANUFACTURING
Abstract: The patternless casting manufacturing(PCM) technique adopts a new method of double scanning which combines the principle of discreteness and deposition with the resin-bonded sand technique. Two main factors, the liquid penetration regularities in the space between particles and the shape and dimension of the agglomeration unit body, are studied qualitatively and quantitatively. This provides the theoretical basis for selecting the forming technical parameters. The experiments verify the analysis.
