Materials and Manufacturing 2 Processing and testing of polypropylene Part A. Injection molding of polypropylene samples for mechanical testing. Introduction Injection molding is the most productive and popular polymer processing techniques. Almost 70% of all plastic parts are made using injection molding. Injection molding of plastics is a process similar to die casting of metals. Molten polymer is injected under pressure into a mold. Method Put the plastic material (Polypropylene)

the summer. The nutritional value of this drink is not very high. With a total of 180KJ per 100ml‚ coke is exceedingly high in kilojoules. To simply show comparisons‚ the recommended daily KJ intake for an average teenager is approximately 8200 (K. Baker‚ 2010). Despite the fact that this drink is fairly high in KJ‚ not surprisingly‚ it does not provide a long energy period for a drinker of any age. To put into context‚ an average 340ml can of coca cola contains 145 calories and over 45g of sugar. Per

SEPERATING CYCLOHEXANE AND TOLUENE BY DISTILLATION Aim: Separate two miscible liquids‚ either by macroscale or microscale process‚ using simple and fractional distillation. Compare the efficiencies of simple and fractional distillation. INTRODUCTION: The purpose of this experiment is to learn how to separate two miscible liquids by microscale process. There will be use of simple and fractional distillation. Simple and fractional distillation efficiencies will be compared. The student should have
