Presenter information

This course is presented by
  • David Jeavons - Consultant
  • David has spent his whole working life in the Injection Moulding industry. After leaving engineering college in 1969 he served a four year indentured apprenticeship with GKN Sankey's Plastic Division. At the time the company was one of Europe’s technology leaders - using robotic take out devices and developing thermosetting technologies as well as structural foam techniques. On completion of this apprenticeship his career moved to materials technology, primarily thermoset resins and polyether foams.
