Design and Fabrication of Mini Injection Molding Machine

Abstract

Injection molding is considered to be one of the most prominent processes for mass production of plastic components. The objective of this project is to design and fabrication of mini injection molding machine to produce the electrical holder and we reduce the machine cost by developing this machine. The scope of the studies are performed which is the study will be using a Polypropylene material reinforced with glass fibers. The project can be divided into four stages. First step is design of the mini injection molding machine and second is the preparation of the material and development of the machine, then third step is injection molding machine used to produce electrical holder. The prepared electrical holder is more cost effective compared to other conventional materials because the plastic is available in environment larger quantity only few reinforcements have to be purchased in a minimum quantity. This may not add material cost because of its minimum quantity requirement (less than 5% by weight of that material). And finally testing of the polymer composite with reinforced glass fiber. The result observed from the experiment has shown that, polypropylene thermal conductivity is decreases by adding of the glass fiber. And increase the hardness by adding of the glass fibers to the polypropylene.
