Compression Molding Techniques Study For Support

Compression molding is one of the most important processing techniques for support. Virtually all the investigations are based on experiment trying due to the complexity of molding process. Combined with the product line for molding automotive interiors introduced by a well-known automotive interior company recently, the computer-assisted software analysis and numerical simulation software simulation have been used in the process of compression molding in order to optimize the molding parameters and solve the quality problems of products. The main new research results are:(1) The molding parameters that play a vital role in improving quality of products were determined by analysis the molding process and quality problems of automotive interiors.(2) By simulating the die closed process with POLYFLOW, this paper provides the distribution of flow rate and pressure of molding compound at the different time, furthermore, calculates the molding pressure that the product required.(3) The distribution of temperature and the degree of cure at different time were analyzed and investigated by simulating the curing process of product. Furthermore, by investigating the influence of different molding parameters, we found that increasing the heating temperature of mold and molding compound was helpful to shorten molding circle and improved mechanical properties of product.
