A Review: Design Analysis and Optimization of Screw Feeder of Injection Molding Machine

In this paper, the design and analysis of the rotating screw of injection molding machine has been presented. The flow of melted material is controlled by the reciprocating screw inside the barrel, where the raw material of the product is melted. The proper flow of melted material is required to obtain better quality of the product. Thus, the rotating screw can be considered as a critical component of injection molding machine and its size varies model to model. The work presented is based on parametric modelling of reciprocating screw. Using developed parametric model of rotating screw, three parameters (radius of screw, feed flight depth and metering flight depth) are required to generate the three-dimensional (3D) model for further analysis. The ease of present approach is very useful for the development of the different types of rotating screw in terms of variation in the said dimensions. The static structural and steady-state thermal analysis has been considered to analyse stresses, total deformation, total heat flux and directional heat flux. The obtained result depicts that has higher yield strength and has low total heat flux value. Thus, can be considered where higher strength is required and for higher wear resistance is preferred for reciprocating screw. During injection molding process, the heater temperature is one of the most important influences on the product quality. In this paper, the temperature of the heater will be examined for different product sizes. The temperature values and distribution will be collected and compared. Results show that when the product size changes, the heating and cooling steps have a slight variation. The simulation results were verified by an experiment. Polymeric matrix composites are the most commonly used matrix materials.[2].
