To support a selection of over 19,000 stock springs, Lee Spring offers a custom spring design service. Reasons for requiring custom spring design could include the customer working to tight space constraints or because specific performance requirements need to be met within the operation.
“Custom spring design from Lee Spring means that the customer is going to be able to get exactly what they want out of a part” explains Nick Lungley, Application Engineer at Lee Spring.
Special forms and features can also be added during the design process, in order to enhance the spring’s properties or to aid compatibility with mating parts.
Custom springs can be required within any industry sector, including automotive, aerospace, pharmaceutical and manufacturing.
“It really depends on the specific requirements of the spring itself” adds Nick. “In particular when it comes to extreme working conditions, springs specified would normally be fabricated from the high end alloy wires, but it also comes down to practicality and meeting the performance requirements and the customer needs.”
In order to specify a custom designed spring, the customer must first supply Lee Spring with a specification form or assembly drawing. The key points that are taken into consideration for a new spring design are the size constraints of the spring, the required working load lengths, the environment the spring is required to work in and the functional longevity.
The manufacturing process time often depends on the requirements of the customer. Lee Spring works with the customer to their required timeline in order to deliver parts when required. To help with product development, Lee Spring can also provide prototypes on a short delivery time if required.
The size of a custom spring can vary depending on the requirements of the application. Lee Spring can coil springs from a diameter of less than 1mm and at the opposite end of the spectrum, very large springs can also be manufactured.
The materials used to manufacture custom springs, depend entirely in the application requirements for the spring. Some of the materials Lee Spring uses include copper alloys, nickel alloys, standard carbon steels, all stainless steel grades and oil tempered wires. The company also uses higher end materials such as MP55N and 718 Inconel. There is an almost limitless range of materials available to Lee Spring, dependent purely on the application and the range available.
