Abstract
PURPOSE: To make possible the manufacture of the castings of intricate hollow inside shapes without using any core of casting sand by inserting the hollow object equal to the inside hollow shape of the hollow casting as a core.
CONSTITUTION: First, a metal die of the shape equal to the inside hollow shape of the hollow casting is made. Next, parting agent is coated on this metal die and a flash pattern material such as wax or the like having been melted through heating is injected to make a flash pattern 1. Next, a metal material which permits low temperatue spraying of metal such as Al or alloy is sprayed to the surface of the flash pattern 1 to a thickness of the extent of not being damaged at the time of casting, whereby the sprayed metal clad body 3 is provided. This clad body 3 is put in a heating furnace 4 and the wax which remains after the removal and recovery of the wax is burnt away. The resultant thin-wall hollow body 7 is set to an outer die 8 by core print pins or bosses 9, after which it is preheated if necessary and casting metal is poured through a sprue 10, whereby the hollow casting is obtained.
