For custom-manufactured springs, our standard lead time is 10 to 15 working days from receipt of a confirmed order. We hold an extensive raw materials stock and manufacture everything in-house with no outsourcing, which allows us to quote and deliver significantly faster than many competitors. For urgent requirements we can often turn around small batches considerably faster. Contact us to discuss your timeline and we will tell you honestly what we can achieve.

Yes. We hold over 250,000 compression and extension springs in stock. Orders placed before 12:00 noon are dispatched the same day, subject to availability. Orders for stock springs can be placed through our online shop or by calling 01623 455500.

There is no minimum order quantity online. For telephone and email orders, our minimum order value is £10.00 excluding carriage and VAT. You can mix and match part numbers from our stock range to reach the minimum order value. For custom springs, contact us to discuss your requirement. We work with customers at all stages of a product lifecycle and do not impose impractical minimums on genuine development or prototype work.

Yes, for stock spring orders you can combine different part numbers to reach the £10.00 minimum order value (excluding carriage and VAT). This applies to telephone and email orders; there is no minimum order charge for online purchases.

Yes. We supply customers in Europe, the USA, India, China and other markets. For international orders please contact us on +44 (0)1623 455500 or email sales@ashfield-springs.com so we can discuss shipping options, lead times and any export documentation requirements.

Orders placed before 12:00 noon are despatched the same day for next-day delivery, subject to stock availability. Orders placed after 12:00 noon will be despatched the following working day.

Send us your drawing, sample or written specification by email to sales@ashfield-springs.com or call C. We respond the same day. If you have a sample but no drawing, we can work from the sample directly. If you have a concept but no formal specification, our technical team can advise on the best approach.

The more detail you can provide, the more accurate our quotation will be. Ideally: wire diameter, outer diameter (or mean coil diameter), free length, number of coils, end configuration (for compression and torsion springs), end type (for extension springs), material, required finish and quantity. For compression springs, load requirements or spring rate are also helpful. If you do not have all of this, send us what you have. Our technical team will ask the right questions to ensure we manufacture a spring that meets your specification.

We manufacture springs from wire diameters of 0.1mm to 8.00mm on our standard CNC coiling equipment. If your requirement falls outside this range, contact us and we will advise on the best route forward.

Yes. We manufacture the majority of our custom springs to customer drawings or samples. If you have an existing spring you need replicated, for example, a replacement for a discontinued component or a spring where the original drawing is unavailable, send us the sample and we will reverse-engineer the specification and provide a quotation.

Yes. Our technical team is happy to offer free advice on spring design, material selection and dimensional specification. If you have a load requirement, a space envelope and an operating environment, we can recommend a suitable spring design. We can also review your existing specification to advise on whether it is optimised for the application and for manufacture.

Yes. We regularly supply springs for prototype and development programmes, and we understand the different requirements of this stage compared to production supply, in particular the need for rapid response, flexibility on quantities and continuity of specification into production. We can often turn these orders around in 5 - 10 working days for small volumes. Contact us to discuss your development timeline.

We manufacture springs in carbon steel (hard drawn and oil tempered), alloy steel (chrome vanadium and chrome silicon), and stainless steel in various grades including 302, 304 and 316. Non-ferrous alloys such as Inconel and Nimonic are available on request for specialist applications. Material selection depends on your application environment, fatigue requirements, operating temperature and commercial considerations. Our technical team can advise you on material specifications.

Our stock range is manufactured from carbon spring steel with a bright zinc and clear passivate finish. We do not stock stainless steel springs, but we manufacture custom stainless steel springs to order in any quantity. Contact us with your specification and we will provide a same-day quotation.

For most general corrosion-resistant applications, 302 or 304 stainless steel is appropriate. For applications involving exposure to chlorides (including food processing washdown, marine environments and medical cleaning) 316 stainless steel is the preferred grade, as its higher molybdenum content provides superior resistance. If you are unsure, tell us about your operating environment and we will recommend the most suitable grade.

Springs can be supplied with a plain finish or in a range of protective and decorative finishes including zinc plating, delta tone and delta seal. We also supply springs shot peened, bead peened or vibratory deburred where the application requires improved fatigue life or surface condition. Our technical team can advise on the most appropriate finish for your environment and application.

Shot peening is a process in which the spring surface is blasted with small steel or glass beads, inducing compressive residual stresses in the surface layer. These compressive stresses oppose the tensile stresses generated during spring operation, significantly improving fatigue life. Shot peening is typically specified for springs in high-cycle applications, elevated stress conditions, or where extended service life is critical, for example, in hydraulic valve systems, safety-critical assemblies and automotive applications.

Yes. Ashfield Springs has been certified to BS EN ISO 9001 since 2003. Our quality management system covers all spring manufacturing operations at our Huthwaite facility and is subject to regular audit and management review. Certificates of Conformity are available on request for all orders.

Yes. We achieved BS EN ISO 14001 environmental management certification in 2013. This certification reflects our commitment to minimising the environmental impact of our operations and to continual improvement in our environmental performance.

Yes. We are the only UK spring manufacturer with membership of both the British Fluid Power Association (BFPA) and the British Valve and Actuator Association (BVAA). These memberships reflect our long-standing specialism in supplying springs to the fluid power, valve and actuator sector, and our commitment to understanding the technical requirements of these industries.

Yes. Certificates of Conformity are available on request for all orders. If you have specific documentation requirements such as material traceability, first-off inspection records or customer-specific quality documentation please advise us at the quotation stage and we will confirm what we can provide.

We consistently achieve a quality and on-time delivery performance rating of more than 99% across our customer base. Over 90% of our customers rate our service as excellent, and 100% would recommend us as a supplier. These figures are based on our own customer satisfaction data and on the A-class supplier ratings we have maintained with OEM customers in the fluid power sector for over 30 years.
