1 Queen's University Belfast Polymer Processing Research Centre Injection Moulding Hands-On Training Seminar 22 nd 23 rd June 2015

2 Queen s University Polymer Processing Research Centre Title: Queens University Injection Moulding Hands-On Training Seminar Date: 22 nd 23 rd June 2015 Venue: Queens University, Ashby Building, Stranmillis Road, Belfast Seminar Overview This seminar will begin with an overview of the process and an explanation of how the flow behaviour of plastics fundamentally influences the injection moulding cycle. Following machine demonstrations, delegates will learn how to systematically setup a new mould and establish the required processing conditions to produce a good quality part. The importance of mould safety during machine setup will also be highlighted. The course will be delivered through a series of hands-on demonstrations and classroom presentations with the majority of time spent at the machine in a practical hands-on environment. Who will benefit? This seminar is specifically aimed at Managers, Supervisors, Operators, Production Staff, Process Engineers and those new to the industry wishing to arm themselves with a fundamental understanding of the injection moulding process. Delegates will learn how to safely setup a new mould from scratch and optimise the process to produce a quality part. Trouble-shooting and analysis of common faults, mechanical testing and material characterisation will also be covered. Seminar Presenters Dr Paul Hanna is a Process Engineer in the Polymer Processing Research Centre (PPRC) at Queen s University Belfast. He holds a Bachelor s degree in Chemical Engineering, Master s degree in Polymer Engineering and a PhD in Polymer Nanocomposites from Queen s University Belfast. He has worked on industrial research and development projects for companies across Europe, North America and Australasia for more than 14 years. Prior to working at Queen s University Belfast, he worked in a high volume contract injection moulding environment and is now responsible for the PPRC s injection moulding activities including new mould prototyping, process optimisation, material selection and the delivery of bespoke injection moulding training courses. Dr Bronagh Millar holds a Master s degree in Chemical Engineering and PhD in Chemical Engineering in Rheology and Extrusion of Polymers both from Queen s University Belfast. She is the Characterisation Manager at PPRC which broadly involves thermal, mechanical, rheological and surface characterisation of a wide range of polymeric materials and products. She underpins the research and teaching activities of the School and carries out consultancy for industry, both local and international. She has written 12 conference/journal papers and in excess of 750 reports for industry.
