Moulding Masterclass

Moulding Masterclass is a compilation of technical articles by plastics injection moulding industry expert John Goff, originally written for magazine publication between October 2009 and July 2013. According to the author, injection moulding processes are frequently developed in the early stages of a product's launch and never revisited. Particularly in today's challenging economic climate where manufacturing costs need to be minimised, it is more important than ever that time is devoted to process optimisation. This collection of 32 articles takes the reader through many aspects of the injection moulding process, from the influence of screw design and speed on melt plasticization, flow and shot consistency, through injection and holding time and pressure, gate sizing, runner systems, mould cooling, clamp forces, systematic process control and more. Each discussion combines theory with recommendations and practical examples seen in diverse manufacturing environments. John Goff has almost 40 years' experience of injection moulding and has seen all sides of the process, having been a senior university lecturer, process engineering manager, consultant and trainer. He has written numerous books and articles, presenting complex technical information in a simple, coherent fashion.
