Engineering assistance and custom manufacturing from Lee SpringLee Spring is promoting its in-depth engineering assistance for customers requiring specialist springs, and also its custom design and manufacturing capability. This is in addition to the company's extensive range of high-quality, off-the-shelf standard spring products.

Spring design and manufacture is highly specialised, and not something that can be provided reliably by, for example, typical small engineering workshops. Getting the design right is vital if custom springs are to be manufactured in small or large quantities and perform as intended.

Lee Spring has around 20 spring design engineers, with a combined total of 200 years of experience, and has been manufacturing custom springs and wire forms since 1918. The resultant depth and breadth of experience and expertise, in both design and manufacture, ensures that both spring designs and manufactured components are of the highest standard.

Customers can make contact by telephone or send an email or drawing to start a project consultation. Whatever the application, location or quantity needed, the timescales of most projects can be met.
