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) in granular form into the hopper. Set the injection molding

A polymer is a substance formed by many molecules that are all strung together to form a long chain‚ and has been around since the beginning of time (Polymer). Examples of different polymers being used in everyday life are things like rubber and starch‚ which are both frequently used in the world (Brewer). Polymers also make up what are known as “polymer creatures‚” which are the things that are used in experiments about polymers. The polymer creatures‚ made out of two different polymers‚ are both

Polymers are a part of our every day life and without them around‚ this world would be very‚ very different‚ if not impossible to live in. However‚ most people do not even know what a polymer is‚ or just how widespread they are around us. Polymers are formed from hydrocarbons‚ hydrocarbon derivatives‚ or sometimes from silicon. They are the basis not only for numerous natural materials‚ but also for most of the synthetic plastics that one encounters in their lives. Polymers consist of extremely large
