The new purpose-built Class 7 clean room at William Hughes’ UK headquarters

Clean bill of health

SINCE William Hughes, a specialist

manufacturer of springs and wire

components, acquired AC Services

in the summer of 2015, the company

has been busy establishing an 80m²

high-specification clean room at its

Stalbridge, Dorset, UK, headquarters.

Rated at Class 7 in accordance with ISo

14644-1, this advanced sub-contract

facility is now open. It is already being

used by some of the best-known

manufacturers in sectors such as

aerospace and hydraulics for the cleaning

of small batch, precision machined and

fabricated parts to meticulous standards.

“From the outset we wanted to create

a facility featuring the latest, modular

clean room technologies and furniture,”

said special processes manager Shaun

tattershall. “We have adopted the

previous solvent and aqueous cleaning

systems – both of which offer ultrasonic

capability – used by AC Services, but

pretty much everything else is new.”

this

includes

high-grade

stainless

steel furniture that is designed to help

minimise particulate levels. What is more,

the open plan clean room has been

designed for optimum product flow

based on the latest lean manufacturing

methodologies.

It will thus prove ideal for any company

looking to sub-contract its cleaning

requirements, not just from the aerospace

and hydraulics industries, but also

defence, nuclear, medical, electronics and

oil and gas.

the new clean room, which incorporates

an inspection dark room so that parts

can be viewed under ultra-violet light, is

already being used for oxygen-related

cleaning applications, predominantly for

aerospace giant Honeywell.

typically, these comprise high-precision

machined components, springs and other

parts that go into oxygen equipment

such as breathing apparatus, facemasks

and ducting. these parts, some of which

are also used in liquid oxygen (loX)

systems, are cleaned using approved

cleaning solvents and solutions.

“the existing class room specification

for these products is ISo Class 8, so our

ISo Class 7 facility is more than suitable

– it’s the equivalent of a Class 10,000

cleanroom using the Federal Standard

209E,” added Mr tattershall.

It is also worth noting that William

Hughes can offer in-house cleaning

verification capabilities. Here, samples

are taken from batches that have been

cleaned. the samples are rinsed with

filtered, deionised water over a 0.45µm

filter membrane.

Any particulates captured are both

counted

and

examined

under

a

microscope. As a result, customers are

assured that their components will

always meet the specified particulate

count.

this confidence is vital, as a contaminated

system component/assembly could result

in a chemical reaction, an explosion and/

or a total system or device failure.

“We take the utmost care with customer

parts and ensure that all cleaning is

compatible with the component being

processed,” added Mr tattershall. “Cleaned

items are placed into hermetically sealed

bags that will not be opened again until

required for further processing, such as

assembly.”

the solvent and aqueous cleaning

systems within the new facility at William

Hughes can accommodate precision parts

up to 300 by 200mm in size. Along with

metallic parts, materials such as rubbers

or plastics (or a combination of these with

metal) can also be cleaned.
