摘要:
A rubber composition in which highly hard particles formed with a rubber-philic coating layer by a fluidized coating treatment are dispersed in a rubber material.
摘要:
An object of the present invention is to provide a method of producing an injection-molded article and a mold for injection molding, which can reliably effect control on a mold section on which a molded article should be left when a mold is opened, thus allow efficient automation of the production process of a molded article, and is applicable to production of a relatively soft molded article. Specifically, the present invention provides a mold 10 for injection molding, comprising: a fixed mold 20 and a movable mold 30 for defining a cavity 50 for molding when the mold is closed; a material injection means 25, 26, 27 provided in at least one of the fixed mold 20 and the movable mold 30, for injecting a molding material into the cavity 50; a molded-article removal means 37, 38 provided in any one of the fixed mold 20 and the movable mold 30, for removing a molded article from the mold after the mold is opened; and a reduced pressure suction path provided in the mold 30 having the molded-article removal means 37, 38 therein and capable of depressurizing the cavity 50. The method of producing an injection-molded article of the present invention employs the mold 10 for injection molding.
