DESIGN AND ANALYSIS OF NEW COUPLING SYSTEM IN INJECTION MOLDING MACHINE TO IMPROVE SCREW LIFE

Injection molding machine is the most commonly used manufacturing process for the fabrication of plastic parts. The plastic being mel ted in injection molding machine and then injected into the mould. The barrel contains recipr ocating screw for injecting the material into the mould and the material is also melted into the barrel. This project deals with,the solution of problem occurred for reciprocating screw of Inje ction molding machine. It identifies and solves the problem by using the modeling and analys is techniques. The problem occurred in the reciprocating screw of machine which is wearing of threads due to affect of temperature of mold materials (flow ma terials) i.e. Nylon,low density polypropylene,polystyrene,PVC etc.,The main work was to model the components of machine with dimensions,and perform thermal analys is with modeled component.
