Method of making a sand mold |
摘要 |
A method of making a mold by the use of sand is started by filling a mass of sand in a mold jacket which is in turn rammed to provide a block of sand. The sand block thus formed is excavated by a cutting device to form a mold cavity. The cutting device is guided by a profiling machine in accordance with a predetermined program which describes the shape of an ultimately desired casting to be manufactured by the use of the sand mold.
