AUTOMATIC SAWING AND MACHINING
In December 1999, Stuga sold six Flowline
automatic sawing and machining centres
following demonstrations of the prototype
at its factory in Great Yarmouth, Norfolk.
The prototype was installed in January 2000
and ten Flowlines in total were installed
during that year. The early success can
mainly be put down to the fact that there
were no economically viable alternatives at
the time.
One of the big problems for German
machines was that they were not particularly
good for the UK’s complex internally glazed
casement windows and the fixed head tooling
systems often struggled to cope with the
many variations thrown up. Stuga’s rotary
tooling system overcame the complexity issues
of British windows. This a specialist field
pioneered by Stuga and considerable resources
have been invested into the technology over
many years. Stuga also put the profile into
the machine on the wide face instead of the
narrow face. This meant that no tooling was
required, such as contour blocks, throughout
the machine. This is one of the key factors
making Stuga machines less expensive than its
competitors.
Having created a successful new machine,
Stuga built many automatic sawing and
machining centres until the ‘credit crunch’
destroyed the market in 2008. After two bleak
years the market started to return, for both
new machines and refurbished ones. With

machines becoming available due to companies
downsizing or going out of business Stuga
purchased a number of Flowlines that were
refurbished to the latest ZX3 specification and
sold back into the market. About half went to
new customers and the rest to Stuga customers
that recognised their machines needed
refurbishing or replacing.
With an estimated design life of around
ten years some Flowlines are clearly past their
replacement date but many fabricators cannot
afford to replace them. These old machines
have been targeted in the last two years when
replacements have been available and quite a
few have taken the chance to trade-in their old

machine and purchase a refurbished one. The
big problem is that many others either cannot
raise the money or cannot justify the finance
repayments. This means that these very old
machines are costing more to keep going. The
key point being not only the servicing costs but
the considerable costs of lost production when
a major breakdown occurs. On top of this the
‘donor’ machines are now rarely available for
Stuga to purchase and refurbish, so buying new
is often the only alternative.
With more than 150 automatic sawing
and machining centres in the market going
back over 14 years there should be an almost
constant stream of replacement business but
insufficient consolidation in the industry
means that margins on producing windows are
tight and the money desperately needed for
replacement is often not there. Stuga has found
its biggest selling machine recently is the ZX4,
which can produce 800 to 1,000 windows per
week. These are mainly the companies that can
afford to invest currently as they previously
invested wisely and kept up their investment
strategy throughout the downturn. The other
big seller is the AutoFlow-2 as it is smaller and
has a much lower price.
Almost every Stuga customer has stayed with
the company over a long time and the main
reason for that is that profits are reinvested
back into giving top class service as well as
developing the machines and the range.
Automatic sawing and machining is, by its
nature, at the front of the production line and
needs top class back-up to ensure it is always
working. This can only be properly achieved by
purchasing from a supplier who can supply this
vital back-up and many cannot.
Stuga offers a service and back-up that cannot
be beaten, with six engineers on the road, a
technically competent coordinator always at the
end of the phone and in-house software. All of
this is available in the UK and, with all parts for
Stuga machines being resourced here, customers
are not exposed to the vagaries of international
cross border transport and different time zones.
Stuga is a British manufacturer owned by Steve
Haines and Gareth Green. As owners they are
based in the UK, and are normally available
to talk to you when the chips are down, not
several hours away in another country.
