Those most likely to benefit from this course are employees from plastics manufacturers, plastics sales people, plastics wholesalers and plastics end users from technical staff to line personnel.
This half-day course will be clear and comprehensive, it will present a precise, non-mathematical introduction to plastics, their raw materials, syntheses, and applications, discussing the manufacture and properties of plastics as a function of the molecular properties of polymers used in the plastics industry.
The course will consist of the properties of the main classes of materials, on the principles of such processes as injection moulding, extrusion, blow moulding and thermoforming polymers. No previous experience will be assumed in the subject matter of the lectures.
Plastics are polymeric materials, a material built up from long repeating chains of molecules. Polymers such as rubber occur naturally, but it wasn’t until the development of synthetic polymers that the polymers tailored to the needs of the industry first started to appear. One of the fi rst commercial plastics developed was Bakelite and was used for the casing of early radios. During the Second World War, plastics such as nylon and polyethylene were used as a replacement material for other materials in short supply. Because the early plastics were not completely chemically stable, they gained a reputation for being cheap and unreliable. However, advances in plastic technology since then, mean that plastics are a very important and reliable class of materials for product design.
The mechanical properties of plastics tend to be inferior to most metals. Because of this, careful consideration must be given to using plastics for structural applications. Fibre reinforced plastics are extensively used where the mechanical properties of the base plastic material are not suffi cient. However because of their relatively low weight, the ability to colour the plastics when manufacturing, and the ability to mould complex shapes relatively easily, plastics are extensively used for product casings and other applications where mechanical strength is not at a premium. Plastics are not cheap materials. The cost of raw plastic materials is typically higher than steel but less than aluminium. However, because processing costs over large production runs are lower, the use of plastics can result in signifi cantly cheaper products.
We will discuss the two main families of plastics, thermosets and thermoplastics and their methods of moulding, i.e. the various methods of blow moulding as well as the various methods of injection moulding. We will conclude with plastic applications in the industry, associated problems, choosing the correct plastic for the application and which aspects of plastics to avoid.
