Abstract

PURPOSE: To reduce impurities and inclusions in cases and improve quality by melting a case blank material then casting the same in molds to produce the bar form long-length object and working the same thereby producing the cases.
CONSTITUTION: A case blank material having specified component composition such as nickel base alloy, stainless steel or other is melted in a heating furnace and is cast in molds to make the bar form long-length object 1. At this time, impurities and inclusions are floated and separated in a molten state at the casting and therefore the bar form long-length object 1 does not contain any impurity and inclusion. The case base material 2 obtained by cutting the bar form long-length object 1 produced in this way to a multiplicity at a fixed width is subjected to forming such as pressing or the like, whereby the case prototype 3 is manufactured. This case prototype 3 further undergoes cutting, grinding, etc. as post fabrication, whereby the finished product of the specified shape may be obtained.
