Abstract: Injection molding process is a method for mass production which includes melting the polymer into the mold by using high pressure and special tools. This process includes different design parameters that may influence the, accuracy, dimensional stability and finally the product quality. The objective of this study is to analyze and review these parameters and identify the one which mostly affect the product quality. Therefore, various techniques are employed to attain the results. The first step involved the selection of the plastic part, then complete design for the mold by using AutoCAD Software. CATIA Software also used in the modeling stage, followed by the product analysis using the Moldflow Insight and the Master Cam programming. In order to fabricate the mold, CNC machine was employed and finally, the injection molding machine was used to test the mold. Based on the comparison of the previous results, recommendations can be derived to assist researchers in solving problems and overcoming the obstacles in improving the product quality. For instance, controlling the cavity pressure during the injection process will give high dimensional stability with no flash during production process. Moreover, a perfect runner design will reduce the possibility of formation a parting line in a product. Also, it can be concluded that when the contact force between the product and the cavity through a suitable design is decreased, the required ejection force to remove the product is also decreased and maintain the product from any distortion with fine quality.
