Springs
are the most highly stressed manufactured components operating in any
mechanism. As a consequence
they are manufactured from the highest strength engineering materials known
to man. They are critical
components requiring a detailed knowledge and appreciation of their
manufacture on the part of all involved in the component supply chain.
This course will provide that essential understanding in 3 days. |
