CONCEPTUAL DESIGN OF INJECTION MOULD TOOL FOR MAIN BODY PART OF AN AIR INFLATOR

This paper presents the conceptual design of plastic injection mould for Main body of an air inflator, which is used for air filling in the dunnage bags. The fundamental aim of the designer is to achieve balance between productivity and design, by optimizing the design, process and manufacturing parameters, which results in the final cost reduction of the mouldings without compromising the quality of the product. The various parameters like processing temperature, pressure, melt velocity, filling time, moulding material, parting line selection, feed system, mould cooling, ejection system, etc. affects the design of mould and its functions with variation in cost and quality for producing optimized quality mouldings. By varying some of the above said parameters an effort is made to attain a cost effective conceptual design. The suggested material for Main body of an air inflator is polyamide 66. Designing of mould is carried out by using computer aided designing software Unigraphic
