Specialist Spring Applications
Ashfield Springs manufactures precision springs for specialist applications in defence, medical and construction, supplying low-volume and prototype spring requirements where traceability, specialist materials and tight dimensional control are essential and are able to continue to support when projects increase to large-scale production volumes.
These applications sit alongside our core sectors and are served by the same ISO 9001-certified quality management system, the same precision manufacturing capability and the same commitment to responsive, communicative service. Where a specialist requirement does not demand the heavy accreditation stack of aerospace or implantable medical devices, we offer a practical and competitive alternative to the high-overhead suppliers who make up most of the safety-critical market.
Specialist Coated Springs and Shot Peened Springs for Defence Applications
Defence applications place demanding requirements on spring performance and documentation. Springs in communication devices, field safety equipment, vehicle systems and weapon system assemblies must perform reliably across extreme temperature ranges, under vibration and shock loading, and in corrosive field environments. We manufacture springs for defence applications in materials including stainless steel, alloy steels and high-fatigue grades, with specialist coatings and surface treatments available:
Shot peened springs for improved fatigue life in cyclic loading applications
Zinc plating, delta tone and delta seal finishes for corrosion protection
Vibratory deburred springs for improved surface condition and consistency
Full material traceability and Certificates of Conformity
We supply springs for defence-adjacent applications including communication device assemblies, vehicle suspension and mechanism components, field equipment and safety systems. Our ISO 9001-certifiedapplications, supply and full batch traceability provide the documentation trail that defence procurement requires, without the overhead of full aerospace accreditation.
Precision Springs for Medical Devices and Medical-Adjacent Equipment
Medical device applications require springs manufactured with exceptional consistency, full material traceability and surface finishes compatible with sterilisation and clinical cleaning. We manufacture springs for medical device assemblies, diagnostic equipment, patient handling systems and laboratory instrumentation, covering:
Small compression springs for actuation and valve mechanisms in medical devices
Precision torsion springs for hinged and rotary mechanisms
Wire forms for contact, retention and guidance functions
316 stainless steel springs for sterilisation-compatible applications
We operate as a practical entry point into precision spring supply for medical-adjacent OEMs who require certificated springs with traceability but whose applications do not require full ISO 13485 accreditation. Our spring design capability, same-day quotation response and short lead times reduce the typical friction of sourcing from specialist suppliers. For applications that do require ISO 13485, our team can discuss the appropriate route forward.
Low Volume Spring Runs and Prototype to Production Continuity
Specialist applications frequently require low volume spring runs. We offer development samples, first-off approval batches or ongoing small-volume production that do not justify the minimum order quantities of volume manufacturers. We are experienced in managing low-volume precision work efficiently, and in maintaining continuity of supply as programmes move from prototype into production.
Our traceability-capable manufacturing process means that springs supplied at the prototype stage can be reproduced exactly for production, with full documentation of material, process and dimensional records. This provides engineering teams and procurement managers with the confidence that approved components can be replicated reliably over time.
Springs for Construction: Hydraulic, Structural and Netting Applications
Construction applications include springs in hydraulic excavator and plant systems, structural expansion and vibration isolation assemblies, access and safety netting mechanisms, and HVAC and services equipment. We supply:
Hydraulic valve return springs and actuator springs for construction plant (via our fluid power specialism)
Springs for access equipment, fall protection netting systems and safety net tensioning
Compression and extension springs for structural and building services applications
Return springs and counterbalance springs for plant and access mechanism assemblies
Our central UK location and M1 proximity make us practical for construction sector customers across the Midlands and nationally. We offer competitive pricing, short lead times and the supply chain responsiveness that construction programme schedules demand.
Traceability, Certification and Documentation
For all specialist applications, we offer full batch traceability from raw material through to finished spring, Certificates of Conformity, and first-off approval sample supply. Our quality management system is certified to BS EN ISO 9001 and provides the documented control framework that specialist procurement teams require. We are happy to discuss customer-specific quality plans, inspection requirements and documentation formats for your application.
