PPT-Injection Moulding Injection moulding is a highly automated  production process for producing

thermoplastic material is heated melted and then forced under pressure into a mould  Once in the mould  the material cools forming a component that takes on the shape of the mould cavity Extrusion. Its low density high transparency and high gloss sidewall strength at high temperature and greater freedom from environmental stress cracking make polypropylene the material of choice for hollow packaging Polypropylene is mainly used in cosmetics de 2 DuPonts offering 2 Polyester resins 2 Nylon resins 2 Underbonnet components 2 Page Air duct system 3 Cooling circuit system 3 CVJboots and bellows 3 Fuel tanks Molding machine .

Over the years, automotive exterior parts have become more complex and substantially larger, yet are molded at faster cycle times. The transformation in design and challenging manufacturing demands have driven changes in tool design, hot runner design, material formulation and molding machine functionality. With these increasing challenges, we have to ask ourselves if conventional methods of quality control, which are typically univariate, are still effective. The short answer is no. This presentation demonstrates how multivariate analysis extracts pertinent information from large amounts of complex data. It is then able to identify the correlation structure and relationships that exist between multiple process variables and present it visually. We’ll present a project comparing univariate and multivariate approaches. These methods hold the promise to both reduce the dependency on subjective, visual inspection and make lights-out manufacturing more viable..
