the ‘British Plastics Federation’ website ‘Plastipedia’ and study the animations of the polymer manufacturing processes. Week 19 3.1.4: Forming, redistribution and addition processes: polymer processes introduce joining methods, adhesives and fixings along with the use of jigs and fixtures where appropriate. Understand the methods that can be used to shape polymers into 3D products. Be able to identify and explain the forming methods used to produce a specific product. Understand how scales of production influence the choice of polymer process. Starter Recall activity using materials from week 18, Students should provide commentary to the animations found on Plastipedia or equivalent source. Activities Using a polymer product handling collection identify features that indicate the moulding process used eg ejector pin marks/mould lines, living hinges. Produce a vacuum form moulding. Explore draft angles and understand the limitations of the process.
