Design Development and Analysis of Manifold and Coupler Body of Air Inflator Product

ABSTRACT Injection molding is a most common and important of all plastic processing process. This process is extremely versatile, and can produce very complex shaped parts, with the use of multi-sided molds. This paper deals with the design development and mold flow analysis of injection mold tool for two components of same assembly and are of different materials (i.e., manifold and coupler body). The part was analyzed with high end analysis software and accordingly the design has been carried out. The tool has been manufactured after some trials and corrections. The mould flow analysis software is being used to predict the parameters like runner location, fill time and weld lines etc before production of the tool. Any product to be manufactured invariably requires machine and tool. Tool design and development is specialized and critical area, the tool design should match the machine specification and should be accurate and economical for good product.
