Machine bends and coils spring steels
William Hughes has added a GBP140,000 Wafios BMS2 CNC wire bending and coiling machine to its wire shape production plant in Dorset.
Wire frame design change speeds car seat assembly
When a wire former was asked to quote for the supply of a bent wire assembly for car seats, its engineers re-designed the component to speed assembly on the production line.
Springs manufactured by William Hughes are used in vital items of aerospace equipment including oxygen systems, access hatches and the solenoid valves used to control the hydraulic and cabin pressure systems.
The company can offer its customers a rapid design and prototyping service in a range of materials.
This service is particularly suited to the aerospace industry where small quantities are required for prototypes with the capability to move to volume production once a final design is agreed.

In addition to bending wire through any plane in any configuration, a company is able to cut or roll threads and apply plastics or painted coatings.
Compact springs square up to high load demand
To meet the demand for compact springs that can handle high loads, specialist manufacturer has introduced a range of torsion springs formed from square section wire.
Quality systems to ISO 9001:2000, ISO/TS 16949:2002 and AS 9100 ensure consistency and accuracy of supply.
To meet the specifications for high temperature performance, many springs for the aerospace industry are manufactured in exotic materials such as Nimonic, Inconel and Ni-span.
These expensive materials are more difficult to work than conventional materials and William Hughes has the machinery and expertise to use these materials with high accuracy and minimum wastage.
Production of compression springs is inspected and measured instantly and accurately using the latest high technology camera/PC based measuring system, determining the length, outside diameter, end coil profile, 'squareness' and parallelism of the spring when it is stood on its ground end face.
For critical applications it is essential that any lubricants and debris from the manufacturing process are removed from the spring before it is despatched to the customer and William Hughes offers an ultrasonic cleaning process to meet aerospace standards for cleanliness.
Following the cleaning process, springs are individually packed and labelled in sealed bags for identification and to ensure they do not get contaminated before use.
Based on this manufacturing knowledge and experience, William Hughes is an approved supplier to many leading companies in the aerospace industry and is an audited and approved supplier to Honeywell.
Other customers include BAE, Eaton Aerospace, Lockheed Martin, Meggit and MEL Aviation.
William Hughes can also supply a wide range of bent wire forms and sub assemblies for aircraft seats and trim panels.
Seat frames are welded or clipped together and supplied as complete pre-assembled units.
These rigid assemblies are ready for immediate use to suit the requirements of the foam moulding process.
