ATTEND ANY OR ALL OF THE THREE DAYS
DAY
ONE COMPRESSION - DAY TWO EXTENSION & TORSION DESIGN
Whether you work in manufacturing, or you source springs for your company, this
course will provide you with information to identify the right spring design for
the right product. Providing a programme that looks at best practice and theory
of Compression, Extension and Torsion spring types. Learn how to establish which
material is best for which spring type and why, about the manufacturing
processes your spring design will undergo to create the final product and
establish the facts about computer aided design and how it can work for you.
DAY THREE FAILURE & PREVENTION
It is a common supposition that most springs fail due to poor design, however it
is estimated that half of all springs that fail were appropriately designed, but
had either been made from sub-standard raw material, badly manufactured or had
been mis-used. Others may fail because something was overlooked at the design
stage. Drawing upon our considerable experience of examining springs that have
failed during manufacture, testing or use this course has been designed to be of
benefit to anyone involved in the design or manufacture of all spring types by
highlighting possible means by which springs may fail and giving advice on how
to significantly reduce the chance of failure, by combining lectures, practical
demonstrations and case histories to provide a complete picture or reasons for
spring failure and possible options for preventing future occurrences.
