Selection of Injection Moulding Main Parameters in Polymer Processing: A Review

An injection system is a heart of an Injection Moulding process and it includes a variety of factors that need to be coordinated and adjusted. This control system covers parameter that are classified as four main parameters: pressure, temperature, time, and distance. Injection Pressure is the pressure needed to move melted polymer material into the mould. Holding Pressure is the phase which come after the injection pressure stage. Barrel Temperature which can be divided into four operated temperature zones in the injection unit consisted of the rear zone, the middle zone, the front zone, and the nozzle zone. Mould Temperature is typically used for cooling the polymer material once it is injected into a mould that has a cooling water channel. A total of 40 research papers have been studied and summarized based on their related parameters that has been used in the analysis. Most researchers includes the Taguchi method in their research methodology. From the analysis, there are four frequently used parameters which are Barrel Temperature, Mould Temperature. Injection Pressure and Holding Pressure in order to produce a product, to improve product with better quality or products with maximum strength. This paper is a review of all the main processing parameters that are involves in plastic injection molding process.
