PRODUCTS & PROCESSES
Lina Ficken, Engineer Team Leader, explains:
“It is important that, following the expansion
process, mouldings are comprehensively
cleaned before further handling and
assembly processes, not least to remove a
silicone coating used during the
manufacturing process.
“Our customers apply the cable protection
systems on site via the application of heat
which shrinks them into position –
temperature is clearly a factor that needs to
be tightly controlled during manufacturing,”
she adds. “MecWash have been able to
configure the cleaning system so that wash
temperatures are held at no more than 40°C,
which in conjunction with the tailored AC33
chemical solution that the company was able
to develop for us, ensures that all material
leaves the cleaning process in the optimum
condition.”
“MecWash worked closely with the Hellerman
Tyton team for many months, developing the
AC33 chemical, which is formulated to clean
the plastic components effectively at low
temperatures,” explains John Pattison,
Managing Director at MecWash Systems.
“MecWash’s expertise in wash chemistry is
based on years of designing tailored
chemicals for the most testing wash
challenges for individual customers, as well
as manufacturing our own range of general
wash chemicals and inhibitors.”
Another long-standing MecWash customer,
Advanex Ltd, based in Nottinghamshire,
came to us with a chemistry conundrum.
Advanex Ltd is part of a global group with
more than 20 operations worldwide,
covering the military and aerospace,
automotive and medical industries.
Their specialist products must be completely
free from all contaminants before they can
be used – consistent cleanliness to a high
standard is essential. To add to the
challenge, the product range includes
extremely delicate components that post
production cleaning processes must not
distort or damage.
The challenge presented to MecWash was
that there was no one process to de-scale,
clean and brighten the components in one
go whilst still offering “during and post
process” protection. MecWash combined

their chemical and process expertise to
provide a solution to all these issues. The
purpose formulated aqueous cleaner
developed for this application cleans and
protects all of the sensitive components and
offers a permanent bright finish. Dull or
discoloured components were de-scaled and
brightened.
Following extensive trials at MecWash’s
dedicated lab at its Tewkesbury headquarters,
the aqueous cleaner combined with the
MecWash AVD 300 aqueous cleaning system
proved it was more than capable of meeting
Advanex’s stringent cleanliness requirements.
Mr Rob Newham from Advanex Europe Ltd,
comments, “We trialled several companies to
achieve improved cleanliness for our parts;
MecWash was not only able to supply the
most suitable equipment, it also provided the
correct chemical formulated to our
requirements, achieving fantastic results that
were beyond our expectations.”
MecWash employs a PhD chemist to develop
bespoke formulations of wash fluid to best
meet the requirements of each individual
customer. Managing Director, John Pattison,
explains, “MecWash understands that all of
our customers have their own specific
requirements and objectives – we work
closely with them throughout all stages of the
project to ensure we achieve the best results
possible, rather than offering a ‘one size fits
all’ approach.
“This attitude has resulted in us building a
number of long-term relationships with
customers who trust us with all of their
component cleaning requirements because
we take the time to really understand their
needs.”
One of MecWash Systems’ existing customers
came to them with another challenge. This
customer provides surface engineering and
component maintenance for steel rolling and
processing equipment.
Prior to maintenance and refurbishment, steel
rolling bearings need to be clean and dry
with all traces of lubrication grease removed.
The particular lubrication grease used for this
purpose is designed to provide continuous
and consistent lubrication to heavy
engineering components under extremely
challenging conditions. The grease is
designed “not to come off”, which meant its
removal was a time-consuming and labour-
intensive manual operation using a
nonenvironmentally friendly vapour
degreaser. The company wanted to move
away from using solvents.
MecWash was invited to investigate and
come up with a practical solution. Thanks to
MecWash Systems’ expertise and chemistry
experience, it was established that the
tenacious grease required substantial
thermal, mechanical and chemical energy to
break it down and remove it from the
bearing surface.
John Pattison says: “After testing off the shelf
aqueous detergents, our chemist returned to
the chemical drawing board and formulated
a purpose-engineered chemical to break
down and remove the grease, and convert it
into both a liquid and a solid form. The
chemical solution AC43 combined robust
detergency and with sophisticated de-
emulsifying technology to remove the
denatured grease and its by-products as well
as simultaneously control the foam
generation via a water-soluble, non surface
active antifoam package.”
Following extensive trials at MecWash’s lab,
the combination of the Duo 600 component
cleaning system and AC43 proved it was
more than capable of meeting the
customer’s stringent cleanliness
requirements.
The customer explained that after trialling
several companies to achieve improved
cleanliness for their part, MecWash was not
only able to supply the most suitable
equipment, they also provided the correct
chemical formulated for their requirements,
achieving fantastic results that were beyond
the customer’s expectations. The change-
over from the labour intensive manual system
has enabled the customer to not only
improve production, cleanliness and output,
but it has also reduced manual handling,
process time and waste.
