Objectives
 Minimise trim waste through trim
optimisation.
 Extrusa de Colombia S.A. primary goal
was to achieve an average waste of 15
%.
 Reduce orders programming time.
 Automate trim process.
 Standardise processes.
 Improve order combination
management.
Key Challenges
 The machines parameters in X-Trim
should match the reality of the plant.
 The machine operators must be able to
understand the trim solution in a
simple way.
Implemented Solutions
 X-Trim (Base Module + Rewinding
Algorithm).
 X-Trim was configured to consider the
machines from the plant, ensuring that
the generated solution corresponds to
the actual production process by
stages.
 Planners were trained to be able to
easily change parameters (default and
by run) depending on the current
reality of the plant (new technologies
development, purchase of new
machines, etc.).
 A report was designed to match the
format of production plans that are
handled in the shop-floor. This brings
the possibility to have a simple to
understand output for the machine
operators .
Specialists in optimised production planning & scheduling
“The implemented solu-
tion has allowed, in
short-time, that pro-
gramming engineers
have the necessary tool
to ensure the best possi-
ble solution. The results
speak for themselves in
terms of saving time in
scheduling process and
reducing scrap.”

2. Key Benefits
 Scrap reduction:
Using X-Trim Extrusa de Colombia S.A.
was able to reduce scrap from 23% to an
average of 13%, improving the quantity
of finished product.
 More efficient machines:
Operator productivity due to the
reduction of knife changes:
approximately 50%. As a consequence,
Extrusa de Colombia S.A. had the
opportunity to increase their production
throughput, without changing the
machines.
 Less programming time:
X-Trim iteration allows the planners to
get many alternative solutions in just
seconds.
 Stock improvements:
The possibility to manage standard sizes
for their side reels, instead of producing
any additional width is a plus in the
process and allows Extrusa de
Colombia S.A. to align their stock with
the market.
Payback
The solution was implemented in 1.5
month. After its go-live, the ROI
(Return on Investment) was of two
months.

“The services provided by
Greycon were complete,
since they begin to ex-
plain how X-Trim works
until it started to run
completely in the plant.
We are very grateful for
having always the sup-
port required, especially
in the complex cases
that were found in the
initial settings.”
