That process embraces both ex-stock for urgent delivery and custom designs to suit manufacturing across all areas of industry, as part of its 23,000+ standard product ex-stock and prototyping-to-production programs.
The Lee Spring compression range includes their unique Bantam mini springs, from 0.64mm outside diameter in cobalt-nickel alloy. Bantam springs find use in medical devices, precision instruments, aerospace and many other control/process/security devices.
Other specialist compression designs include AISI 316 stainless Lite Pressure variants for use where a low pressure and large diameter spring is required to spread force over a relatively large area, for example in relief/check valves, electrical contacts, toys, syringes etc.
Mainstream die springs, under the HEFTY banner with their high performing round wire section, offer a like-for-like performance at typically 1/3 to 1/2 the cost of traditional rectangular wire units. They are extensively used in non-die applications where their performance/cost profile enables users to also benefit from their high quality and reliability.
In similar vein, the LeeP series of plastic composite compression springs combine the strength of metal with the special attributes of high-performance engineered thermoplastics. This approach maximises spring rates and cycle life with high strength to weight ratios, along with high corrosion and chemical resistance. In addition, of course they are non-magnetic, non-conducting and non-contaminating, as well as being recyclable and RoHS/REACH compliant.
Since the specification of compression springs is often a matter of physical testing – and for the convenience of one-off frequent users in development or service sectors - Lee Spring also have available a set of kits containing a selection of different sizes of compression springs in music wire or stainless steel.
