SOAP-MOLDING DIE

摘要

A soap-molding die is composed of a set of split dies (1A, 1B) assembled together, and inside of the molding die is a molding cavity (1C). The surface area of a recess (11A) forming the cavity in one spilt die (1A) is made larger than the surface area of a recess (11B) in each of the other split dies (1B), and the ratio between the surface area of the recess (11A) in the one split die (1A) and the surface area of the recess (11B) in each split die (1B) is set 52:48 - 66:34. Further, surface roughness (Ra) of the recess (11A) is made greater than surface roughness (Ra) of the recess (11B), and the difference between the surface roughness (Ra) of the recesses is set 0.1 - 30 mum.
