Review on Experimental Design, Process Parameters and Responses of Compression Moulding Process

Compression moulding is a process in which a mixture of material is placed into a mould cavity and compressed especially in composite productions. The aim of this review paper is to find the influence of various process parameters towards various output responses and to determine the most suitable experimental design. It is found that mould temperature was the most selected parameters however preheat time and weight of material are rarely mentioned in the compression moulding process. Meanwhile, tensile strength, young’s modulus and flexural strength are the most output responses investigated. Further, experimental matrix design using the design of experiment (DOE) approached is rarely used in the selected studies where many previous researchers applied one-way method in their research. Thus, we can conclude that the implementation of DOE in experimental study in the compression moulding processes is still lacking and need to be studied deeper.
