Abstract
Now a day’s plastics are used in many of the component and they are replacing many metals in some of the engineering applications. Major advantages of using plastics are formability and they provide a low cost to the performance ratio. The different processes used to fabricate plastic components are extrusion, injection moulding, blow moulding, rotational moulding, and compression moulding, by far the most used process for plastics is injection moulding. Plastic injection moulding is one of the most popular manufacturing processes for making thermoplastic products, and mold design is a key aspect of the process. Design of moulds requires knowledge, expertise and most importantly experience in the field. For this work, the project is to design a plastic mould for Hand Guard. The design is made considering the manufacturing resources and ability of the company within minimum possible time and at least cost of manufacturing. The tool should be able to accommodate minor modifications. The component is designed and modeled in 3-D by using PRO-E software and then analysis of the component is performed in the Mold Flow Plastics Advisers. And detailed design procedure is explained considering all process parameters and design calculations, methodology used, material used for moulding, mould steels recommended and their properties.
