Abstract:

Injection molding has been a challenging process for many manufacturers and researchers to produce products 

meeting requirements at the lowest cost. Faced with global competition in injection molding industry, using the trialand-error approach to determine the process parameters for injection molding is no longer good enough. Factors that 

affect the quality of a molded part can be classified into four categories: part design, mold design, machine 

performance and processing conditions. The part and mold design are assumed as established and fixed. During 

production, quality characteristics may deviate due to drifting or shifting of processing conditions caused by 

machine wear, environmental change or operator fatigue. 

Determining optimal process parameter settings critically influences productivity, quality, and cost of production in 

the plastic injection molding (PIM) industry. Previously, production engineers used either trial-and-error method or 

Taguchi’s parameter design method to determine optimal process parameter settings for PIM. However, these 

methods are unsuitable in present PIM because of the increasing complexity of product design and the requirement 

of multi-response quality characteristics.

This article aims to review the recent research in designing and determining process parameters of injection 

molding. A number of research works based on various approaches have been performed in the domain of the 

parameter setting for injection molding. These approaches, including mathematical models, Taguchi method, 

Artificial Neural Networks (ANN),Fuzzy logic, Case Based Reasoning (CBR), Genetic Algorithms (GA), Finite 

Element Method(FEM),Non Linear Modeling, Response Surface Methodology, Linear Regression Analysis ,Grey 

Rational Analysis and Principle Component Analysis (PCA) are described in this article. The strength and the 

weakness of individual approaches are discussed. It is then followed by conclusions and discussions of the potential 

research in determining process parameters for injection molding
