In the recent years, many corporations or institutions are voluntarily working on the reduction of industrial waste that is environmentally harmful, in order to conform to the ISO 14001 (Environmental Management System). Some laws regarding recycling have been put in force. Such activities are the roles of enterprises. Our company is manufacturing various molded resin products to be used as the component parts for automobiles. In the resin molding process, wastes such as sprue or runner which are not the intended products are generated. These wastes have been treated by the industrial waste processing companies or raw material manufacturer. Such treatment cost affects our material purchasing cost. The treatment of such wastes in our company could reduce the cost as well as solve the problem of the environmental issue. To reuse the wastes, the runner was crushed in a runner crusher and then mixed with virgin resin as the material for the molding machine. Parameter design was conducted for optimization. As a result, the crushing process was proved to be superior to the existing one.
