The plant fiber tableware dry-hot forming process was optimized by response surface methodology. Three independent variables, such as molding pressure, molding temperature and molding time have significant effects on the appearance quality of tableware. A three-factor quadratic regression rotation combination design was employed to study the response, and the interaction of the factors on the appearance quality was also investigated. By analyzing the response surface, a polynomial regression equation was obtained and the optimal conditions of dry-hot forming process were gained, they are: molding temperature of 181℃, molding pressure of 18MPa, and pressure duration time of 9s.
