offers components that can be used across all industries – from medical systems to cars and even toys.
A huge range of springs is available from Lee Spring. Among these are Extension Springs, which are ideal for applications such as automotive interiors and exteriors, garage door assemblies, vise-grip pliers, carburettors and butterfly valves, trampolines, washing devices, farm machinery, toys and, the company claims, thousands of other uses.
Extension springs are attached at both ends to other components so that when these components move apart, the spring tries to bring them together again. These absorb and store energy as well as creating a resistance to a pulling force. It is initial tension that determines how tightly together an extension spring is coiled; and this tension can be manipulated to achieve the load requirements of a particular application. Extension springs are wound to oppose extension – they are often tightly wound in the no-load position and have hooks, eyes, or other interface geometry at the ends to attach to the components they connect. They are frequently used to provide return force to components that extend in the actuated position.
Compression Die Springs are another solution available. According to the company, these are ideal for use as die springs or as heavy duty compression springs for any high stress, heavy load, application. So, alongside use in dies, these are suitable for applications in clutches, brakes, farm machinery and aircraft mechanisms.
Lee Spring also provides components that meet the demands for precision, perfect finish, durability and reliability, standardisation and customisation within the pharmaceutical and medical industry. A wide range of applications are included:
• Springs for pharmaceutical delivery systems: syringes, check valves, pill dispensers, pill counters, fluid control, intravenous valve controls, pharmacy automation, automated drug management, and liquid and dry powder inhalation devices.
• Springs for medical devices: surgical tools and instruments, staple guns, orthopaedic tools, suction lines, catheter valves, peristaltic pumps, anaesthetic infusion, sterilisation valves, fluid control valves, and sterilisation equipment.
• Springs for related devices: shunt valves, wheelchairs, medical instrumentation, diagnostic devices, centrifuges, testing, monitors and inductors, booms, lifts, accessories and air flow management systems.
