Patent JP-S63264317-A (JP)
Title: Porous mold and manufacture thereof
Inventor: SUZUKI TSUNEO
IPC: B29C33/10
Filed: 1987-04-22
Abstract: PURPOSE:To obtain a porous mold useful for injection molding of metal or synthetic resin by a constitution wherein the mold is formed in a state of being separated into a dense layer and a coarse layer. CONSTITUTION:Slurry prepared by mixing a mixture of stainless steel-based powder and boron or metal boride with binder, which evaporates during drying and solidifying processes, is cast in a frame 4 supported by elastic bodies 4 so as to be solidified and molded while being vibrated. Due to viblation, material having comparatively large specific gravity in the slurry gathers to the bottom of the frame 3 so as to form a dense layer 1. Material having comparatively small specific gravity gathers to the casting surface of the frame 3 so as to form a coarse layer 2. The resultant compact is sintered under vacuum after drying, resulting in turning the dense layer 1 into a structure wherein the mechanical strength becomes strong and the void ratio is small, and the coarse layer 2 into a structure wherein the mechanical strength is not so strong and the void ratio is large. The resultant mold has a porous or air permeable structure. Due to the large strength of the dense layer, when fine engraving is applied on the dense layer side, no mold collapsing occurs even after repeated use.

Title: Method for giving water resistance to dry alumite layer
Inventor: YOSHIDA ICHIROU
IPC: C25D11/24
Filed: 1981-06-25
Abstract: PURPOSE:To generate no surface crack even if water is used at the time of a specular surface treatment, by placing a dehydrated dry alumite layer in an atmosphere in which the ratio of water content gradually increases. CONSTITUTION:An alumite plate having a dehydrated dry gamma-Al2O3 film is placed  on a plate 11 of a porous shape, etc. Its surface temperature is set in advance to a higher temperature than that in a water absorbing tank 10 heated by a heater 13 controlled by a device 17. Subsequently, vapor evaporated from a water tank 12 is set to maximum 60% or so by relative humidity throughly controlling a temperature of a heater and cooler 14 by a device 16. Vapor and air in the tank 10 are made to circulate by a fan 18 and are uniformly distributed. After that, a temperature of the device 14 is raised again to about an internal temperature of the tank 10. As a result, relative humidity in the tank 10 gradually approaches 100%. In this way, an alumina film contacts with vapor of each humidity, and a gamma-Al2O3.3H2O film is formed. After that, even if it is made to contact with water, its internal alumina layer absorbs no water, and accordingly, no crank nor film breakdown is generated in case of specular surface finishing.
