Products / Services
Design
Our design and application engineers enjoy state-of-the-art facilities for the in-house design of products and machine tools.
Springs
Bespoke Spring Manufacturer
Precision-engineered springs remain at the centre of mechanical systems, delivering force, motion control and resilience across multiple sectors such as aerospace, automotive, medical, and nuclear. William Hughes offers full-service support from concept to production, underpinned by advanced CNC coiling technologies, statistical quality control and an integrated automation approach. Recognised as a leading Tier 1 manufacturer by assembly-level OEMs for springs and spring assemblies, we specialise in close-tolerance spring design optimised for performance-critical environments. Our engineers ensure every component meets your specification for load, free length, fatigue resistance and material compliance.
Bespoke Springs for Complex Applications
As one of the UK's longest-established spring manufacturers, our engineering team brings over 100 years of sector-specific expertise, supporting product design from early-stage feasibility to validation and final release. With advanced simulation tools, Institute of Spring Technology design software, in house fatigue testing facilities and CNC coiling capabilities, we reduce time-to-prototype while maintaining full control over the physical dimensions and the load profiles.
Every spring is defined not only by geometry, but by its behaviour in application. That’s why we collaborate closely with R&D and procurement leads across the automotive, medical and aerospace sectors to design prototypes with mechanical integrity, consistent repeatability and the best possible cost-to-performance ratio.
Using our CNC coilers and closed-loop vision systems, we can produce springs with sub-millimetre accuracy, sorting components in real-time with SPC (Statistical Process Control) technology. Whether you’re designing for fatigue, rebound, corrosion resistance or magnetism, we’ll ensure your specification is both feasible and manufacturable at scale.
Wire Forms & Assemblies
If you have a 2D or 3D wire form that involves twists, turns, spirals, protrusions, indentations or just plain bends, we have both the expertise and the state-of-the-art automation to provide exactly what you need.
We also have the facility to design and manufacture tools, jigs, and gauges in-house, which means that not only can we test designs for feasibility before manufacture, but it also greatly reduces the lead time compared to outsourcing.
Aerospace
PCB Test Points
Prototype work and volume production
Our PCB test points and terminals feature a large loop for easy probe attachment or to facilitate the clipping on of other components. They are ideal for components which need frequent replacement and are also suitable for raising hot components above the surface of the PCB.
A glass bead in a choice of eight colours for identification purposes ensures a snug fit on the board. White, yellow, black, brown, blue, pink, red and green are available ex-stock with other colours to meet special requirements. The unique shape of the test point will not damage through-plated holes during assembly yet prevents any movement prior to soldering.
Passivation
ISO Class 7 Cleanroom
The cleanroom ensures that hydraulic, LOX (liquid oxygen), oxygen and other critical components can be cleaned to the most demanding quality standards, approvals and specifications. It incorporates an inspection dark room so that parts can be viewed under ultra-violet light.
Automotive
William Hughes started to supply the automotive industry nearly 30 years ago. Now it forms the largest part of our business, but our success has not been lightly won. It has been achieved by constant investment in new technology, the support of a highly skilled and dedicated workforce and by adhering to the highest quality standards.
Our global customer base includes Johnson Controls, Lear Corporation and CTS (global oem suppliers to the automotive industry). Also Proseat, Fehrer and such smaller companies as The Seat Design Co. and CAB Automotive which specialise in low volume production for the luxury car market.

With decades of specialist knowledge, the Polish site supports William Hughes’ wider manufacturing operations, supporting large-scale production with full quality traceability, consistent throughput, and automotive sector compliance.
High-Volume Welding, Assembly and Wire Forming
Our Polish site specialises in the high-volume manufacture of welded wire assemblies, including automotive seating structures, seat mats and torsion bars for applications, including electric vehicle (EV) and ICE assembly. As OEMs transition towards lightweight and modular EV design, our capabilities allow for the efficient manufacture of wire-based structural supports, battery compartment reinforcements and vibration-dampening spring assemblies.
Cataphoretic Paint Line (KTL)
William Hughes Bulgaria
Our original 2000 square metres now stands at 6,500. Our work force has more than trebled to 200 skilled employees, even allowing for the fact that we have added automation-handling robots for secondary processes and collaborative robots for packing and repetitive tasks.
The Plovdiv factory now houses over 50 CNC wire bending machines along with 9 injection moulding machines for over-moulding projects.
About us
With factories in Stalbridge, Dorset and Plovdiv, Bulgaria, each benefitting from a multi-million pound investment in plant and machinery together with the recent acquisition of Nosag Polska in Poland, William Hughes combines modern technology with traditional skills to bring products to market in the most refined, cost-effective and timely way possible.
These products comprise a broad range of compression, tension and torsion springs, wire forming including simple and complex 2D and 3D wire forms, printed circuit test points and terminals, and specialist wire sales.
Throughout the past two centuries, the success of William Hughes has been based on the traditional virtues of a family firm - commitment to its customers, concern for quality and service - allied to continual improvements in production and technology to meet the precise specification of each individual requirement in the most appropriate way.
The resources provided by William Hughes are amongst the most extensive and sophisticated in Europe, with the capability of fulfilling orders, however large or small, with equal facility, and an established administration and distribution function that ensures continuity of supply, rapid delivery and competitive prices on every single item.
The variety of springs and wire forms available is almost infinite in a choice of metals which is nearly as wide including stainless steel, brass phosphor bronze, beryllium copper and nickel-chrome alloys.
PROTOTYPING
William Hughes has many years of design and manufacturing experience and can offer its customers a rapid design and prototyping service in a range of materials. This service is particularly suited to the aerospace and automotive industries where small quantities are required for test and evaluation with the capability to move to volume production once a final design is agreed.
SUB-ASSEMBLIES
Through the 90’s the company expanded to includes the manufacture of sub-assemblies. These sub-assemblies are still based on wire but techniques have been developed such as welding, punching, pointing, chamfering, nibbing, threading, clipping and many more that add value to the product for our customer. Through the next decade we expanded our range of in-house surface treatments to include shot peening, ultra-sonic cleaning, KTL black coating, painting, Delta-Tone™ and nylon coating.
OUR EUROPEAN OPERATION
In 2004, sensing the need to address the challenge of an expanded Europe, William Hughes set up a purpose-built factory near Plovdiv in Bulgaria, the better to compete in an increasingly cost-conscious market and also to facilitate speedy delivery into its many customers in mainland Europe. Today our Plovdiv factory has twice doubled in size and is currently around 6,500 square metres.
Our work force has more than trebled to 200 skilled employees even allowing for the fact that we have added automation-handling robots for secondary processes and collaborative robots for packing and repetitive tasks.
The Plovdiv factory now houses over 50 CNC wire bending machines along with 9 injection moulding machines, both vertical and horizontal, for over-moulding projects utilising rotary and fixed platens.
