Disponible en CD en formato PDF Transcripción del abstract original del autor: Substituting metal parts by plastic parts is one of the most effective ways in reducing manufacturing cost of various kinds of engineering components. Therefore, the substitution has been undergoing in many kinds of fields such as automotives, electric appliances, and gas appliances. It has other benefits other than cost reduction such as -making appliances lighter, -reducing the number of parts by integral molding, and -improving the heat insulation, In this study, the authors attempted to develop headers and joints for hot water supply especially for gas central heating system.
