Abstract: The present invention provides a method of preparing a molded body good in processing properties, having fine contiguous pores throughout it. The surface texture of the body is fine. The body is excellent in thermal conductivity and heat-resistance properties, can be readily prepared, and is usable as a transferring mold. The method comprises compounding and mixing 5-20 parts by weight of a binder consisting of a modified amine and a modified M. D. I. that are both liquid with 100 parts by weight of an aggregate consisting of aluminum powders or aluminum-based alloy powders, filling the mixture in a-molding flask, and compressing it under a pressure per unit area of 20-80kg/cm2, and maintaining it under the same pressure until the binder is hardened.
