DIRECT SHELL PRODUCTION CASTING

Nandish Datti


DSPC is a proprietary technology developed at Soligen.

Its core technology is based on Three Dimensional Printing (3DP) a patented technology invented at the Massachusetts Institute of Technology (MIT), and licensed exclusively to Soligen for the metal casting field of use.

Direct Shell Production Casting (DSPC) fabricates ceramic shells (molds) that can be used to cast metal parts.

The system creates ceramic shells directly from 3-D CAD designs and no too ....etc

Stir casting is an economical process for the fabrication of aluminum matrix composites. There are many parameters in this process, which affect the final microstructure and mechanical properties of the composites. In this study, micron-sized SiC particles were used as reinforcement to fabricate Al-3 wt% SiC composites at two casting temperatures (680 and 850 C) and stirring periods (2 and 6 min). Factors of reaction at matrix/ceramic interface, porosity, ceramic incorporation, and agglomeration of the particles were evaluated by scanning elec ....etc

Conventional stir casting process has been employed for producing discontinuous particle reinforced metal matrix
composites for decades. The major problem of this process is to obtain sufficient wetting of particle by liquid metal and
to get a homogenous dispersion of the ceramic particles. In the present study, aluminium metal matrix composites were
fabricated by different processing temperatures with different holding time to understand the influence of process parameters
on the distribution of particle in the matrix ....etc
