Optimization design of wall thickness distribution of hollow blow molded products based on response surface analysis

In order to solve the problems such as excessive or insufficient mechanical properties, waste of raw materials, and so on, caused by the empirical method of determining the wall thickness of blow molded products, this paper proposes a mathematical model by using response surface analysis and finite element analysis. The wall thickness distribution of the product is studied with the goal of minimizing the weight of blowing molded products and improving their mechanical properties. The best wall thickness distribution of the product within the limited target conditions is obtained and it provides reference of selection standard for the wall thickness size in the R&D stage of product development. The results showed that through response surface analysis and finite element analysis, the optimal wall thickness distribution of blow molded products can not only improve the mechanical properties of the products, but also reduce the weight of the products, and save the raw materials and the cost of production.
