Abstract
PURPOSE: To let the decorative plate be fitted and fixed without any spacing to the case body by inserting the decorative plate at the time of compaction-molding the case body and sintering the resultant molding at high temperatures.
CONSTITUTION: A decorative plate 2 composed of super hard alloys such as WC and TiN with Ni, Fe, Co, etc. as a binder or ceramic materials such as CrB is fitted in the groove part 3a of a lower die 3, after which stock powder 4 for molding case body is packed between a knock-out 5 and outer ring 6. Thence, it is compaction- molded by pressing a punch 7. The resultant molding is sintered at high temperatures, whereby the decorative plate is secured to the case body. This method enables the decorative plate having fine and intricate plane shapes to be fitted closely to the case body.
