Lee Spring is promoting its compression die springs. The company uses its round wire coil production technology to ensure optimal performance and longevity priced at around 50 per cent to 60 per cent of competitor costs. The "complete spring" philosophy of Lee Spring means that their die springs have ground ends as standard for a large surface bearing area square to the operational axis, plus they are shot peened in production for longer life. Preset length in manufacture assures consistent length in use to suit applications ranging from automotive transports and large stamping presses, to major appliances and lawn mowers, as well as medical devices, mobile phones, electronics and sensitive instrumentation devices.
