Patent number: 11285449Abstract: A method for producing a sealant includes a weighing and mixing step, a kneading step, a stirring and defoaming step, and a filling step. In the weighing and mixing step, a main component and a curing agent are weighed and mixed together. In the kneading step, the mixture mixed in the weighing and mixing step is kneaded. In the stirring and defoaming step, the kneaded product kneaded in the kneading step is stirred and defoamed. In the filling step, the kneaded product defoamed in the stirring and defoaming step is filled into a container. In the stirring and defoaming step, the kneaded product is stirred under a condition wherein a stirring rotational speed at which the kneaded product is stirred and a stirring time for which the kneaded product is stirred are within a range from an arithmetic product lower limit value to an arithmetic product upper limit value.Type: GrantFiled: March 22, 2018Date of Patent: March 29, 2022Assignees: MITSUBISHI HEAVY INDUSTRIES, LTD., KAGA SANGYO CO., LTD., KAGA WORKS CO., LTD.Inventors: Shigemi Yamane, Osamu Mizoguchi, Hitoshi Tsujikawa

Patent number: 10493668Abstract: Molding methods and molds for making a synthetic resin molded product include disposing a curable liquid resin mixture in a recess of a female mold. The curable liquid resin mixture is then simultaneously agitated and degassed by a mixer while under a partial vacuum. More specifically, at least the female mold is orbited around an orbital axis while being rotated about a rotational axis that is eccentric to the orbital axis. After being thoroughly mixed and degassed, the liquid mixture is then cured in the mold unit.Type: GrantFiled: December 10, 2018Date of Patent: December 3, 2019Assignee: KAGA SANGYO CO., LTD.Inventors: Osamu Mizoguchi, Takayuki Nomura, Hitoshi Tsujikawa, Yoshiki Ikeda
