Optimization Techniques in Compression Moulding: A Comprehensive Review

Abstract

Quality and productivity have been used as terms to control process parameters and lower process defects. Several defects emerge when products are manufactured using the compression moulding process.Since the second-largest industrial process used to produce plastic goods and also the most popular method of producing thermoset and thermoplastic polymer composites is compression moulding.By this method control of temperature and pressure gives the desired shape of product. This method can be applied to both thermoset and thermoplastic materials. Due to the low flow index of thermoset plastics, considerable pressure is needed, which can only be achieved by the compression moulding method.The components, functionality, equipment, and tooling behaviour of the compression moulding process are covered in this study of paper. The advantages, drawbacks, and equipment used, as well as the material processing parameters, part design, tooling, and cost of compression moulding process parts are also discussed.In this work, many process variables—including moulding temperature, pressure, preheat time, and material weight are taken into account for the response research of the mechanical properties and internal defects created by the compression moulding process.
