Analysis of Molding Process Parameters of Bra Cup

Abstract

Polyurethane foam is the material most widely used in bra cup production. From the main factors affecting the molding process of molded cup, this article analyzed the properties of polyurethane foam, and elaborated the principle of molding from the molecular structure of polyurethane foam. Then, a set of molding experiments has been done for three different parameters of materials. The results of the experiment analyzed the molding process parameters of the polyurethane foam, and summarized the main factors affecting the same. The work aims to develop a quantitative control method for bra cup modelling process.
