Info

On page 164 you will find a glossary which will help explain theterminology used in specifying custom springs. Between pages 153and 162 you will find specification forms for several types of springsalong with guidelines to assist selection.We also have the capability to produce many other types of springs,washers, wire forms and stampings as well as assemblies of theseproducts. Please contact us to discuss your particular application.As you most probably know, round wire die springs perform as wellas rectangular wire form die springs. The only difference is theygenerally cost less! This is because it is more efficient to producesprings from round wire rather than from the rectangular wire formtraditionally used. Moreover, you will enjoy the increased durabilityof chrome silicon steel or music wire which has always been thematerial of choice for steel springs.Spring kitsDeveloped with research and development engineers, techniciansand maintenance specialists in mind, our spring kits comprisea selection of different sizes and are available for standardcompression, extension and torsion springs as well as instrumentsprings. See page 4report the IST stated:Independent tests, undertaken at theInstitute of Spring Technology (IST), haveproven that Lee Spring’s round wiresprings have a life expectancy equal tothat of rectangular wire die springs. In itsQualityOur quality system is assessed by and registered withISO 9001BUREAU VERITASCertificationNº 5692Bureau Veritas to the requirements of BS EN ISO9001:2000 – certificate number 5692. This approval isthe cornerstone of our service and commitment to total qualitymanagement.RoHS All✓COMPLIANTour springs satisfy EU Directives on the Restriction ofHazardous Substances (RoHS) 2002/95/EC and WasteElectronic and Electrical Equipment (WEEE) 2002.96/EC.Batch traceability is a standard procedure on all orders, regardlessof quantity. Batch codes are fixed to all packages prior to despatch– the same coding appears on customers’ packing notes and ourfile records. Full traceability is achieved from raw material intaketo finished products. A Certificate of Conformity is issued free withevery packing note. Additional copies are charged at £10.00 per copyper spring type.Customer ServiceWhatever your requirements; springs for repair or maintenance,development work or batch production, our trained telephone salesstaff will help you select springs from this catalogue.We can accept credit card transactions and open accounts for newcustomers immediately.Whether you are ordering one spring or thousands we welcomeevery enquiry and each order receives the same professional service.Order on lineOrder springs online at www.leespring.co.uk. Via our web pagesyou can also access a vast engineering database that will help youcalculate spring characteristics and select types to meet specificperformance and application parameters. Once a spring is chosenfull technical details, including dimensions and loads can be accessedalong with price information.Users can view and manipulate images of stock springs anddownload 3D or 2D CAD models in all major platforms or view andsave images as jpg. or tiff. files.‘In terms of fatigue life, all springs completed the required 3,000,000cycles without failure and as such no fatigue ranking of the batchesA, B, C, and D (supplied) is possible’.Spring materialsOur stock spring range is manufactured from materials to military,aerospace and/or equivalent British or DIN standards, with designand manufacturing tolerances in accordance with British andInternational standards. Standard music wire and oil tempered MWsprings are zinc plated, passivated and fully de-embrittled whileour stainless steel springs are passivated to optimise their corrosionresistance.Springs manufactured in type 316 stainless steel offer severaladvantages over type 302 type stainless. Corrosion resistance isgreater, especially in chloride environments, purity levels are higherand therefore colour is more consistent. All our type 316 springs areultrasonically cleaned as well as passivated to offer medical and foodgrade levels of cleanliness.Engineers GuideOur 28 page ‘Engineers Guide to Designing & SpecifyingCompression, Extension and Torsion Springs’ hasbeen around for so long it is considered to be abenchmark publication in the spring industry. The‘guide’ lists key design factors and providescalculations in line with the most recent BritishStandards applicable to spring design and materialsspecifications. Copies are still available free.
