New technologies.
Innovation is another key focus of Granco Clark.
The most important new technologies, and the most
productive refinements of existing components have
come from Granco Clark, and many—like our Hot
Jet furnace—have become industry standards.
Don’t let productivity slip away.
Sure, huge breakdowns and line stoppages are
dramatic and costly. But in truth, most threats to
productivity are more subtle and insidious. Things
like ineffective inventory management, poor furnace
efficiency, balky handling systems, imprecise die
ovens, and many others that detract from your line’s
overall performance and cost you money.
4. The Granco Clark Hot Saw and Spinning
Log Welder improves metal management. The Hot
Saw cuts billets to the size needed just before the press,
with lower pressure and no deformation. Blade area is
kept clean and chips are removed quickly by the highefficiency chip collector, to be processed for reuse.
Short, compensation-cut pieces are held for pairing
with another piece to form the correct size billet,
achieving 100% billet consumption.
1. Granco Clark’s Billet
Sawing System lets you store
large standardized logs, and cut
them to the appropriate size
needed on their way into the
furnace. A clean, square cut,
performed at room temperature.
Less space and money tied up in
inventoried logs.
Log ends are fused together to form single billets
using integrated Hot Saw and Spinning Log Welder
technology. The Hot Saw cuts log ends to expose
fresh surfaces. The Spinning Log Welder then pushes
the pieces together under pressure and controlled
rotation. And it all happens after the furnace where
it can be done most efficiently. The process provides
a more complete bond forming virtually seamless,
uniform single billets—and increases yield 1–2%.
2. Granco Clark’s Hot-Jet
Furnace is the most energy-efficient
billet-heating furnace on the market,
delivering an average thermal efficiency
of 55%. A “hot-jet” preheat section
captures and re-circulates exhaust gases.
A pressurized entrance chamber blocks
cold air from entering and keeps
preheated gases in.
5. When integrated with the Hot-Jet Furnace, Granco
Clark’s Quick-Cycle Log Shear uses high pressure
to cut billets to size as needed at just the right time.
The shear ring design and precision clamping system
deliver a square cut with minimal deformation.
Short, compensation-cut pieces are automatically
transferred back to the furnace between shearing
cycles—allowing 100% of the log to be
consumed, with no scrap.
3. Granco Clark’s innovative Taper
Quench compensates in advance for
the heat buildup in the billet during
extrusion. A high-pressure water quench
subtracts heat selectively to create a
computer-calculated temperature
gradient to assure optimum
temperature at the moment of
extrusion. This helps assure
consistent profile quality
and minimizes scrap.

8. Granco Clark offers a selection of Stretcher
Technologies to cool profiles. The High-Pressure
Spray Quench uses strong spray jets for fast, even
cooling. The versatile Flex2 Quench lets you choose
spray or air quenching to accommodate a wide
range of profile types.
Technologies to meet different operational and
manpower needs. The Controlled Vertical Crush
Stretcher delivers precise control of stretching to
ensure the highest-quality profiles. It has a unique
pivoting upper jaw that can be set to any closing
dimension. This minimizes the distortion that can
be caused by traditional jaw designs.
Also available are Water Wall quenches, Overhead
Duct Cooling Systems, and an Integral Runout
Cooling System that places an adjustable stream
of air from ducts located beneath the runout
table, for excellent performance and maximum
space efficiency.
As one of the world’s leading extrusion equipment
manufacturers, we know what we’re doing. Each of
our technologies is developed and refined with
real-world know-how. And our experience allows us
to optimize the performance that can only come
from a thoroughly integrated unit. With quality
components designed to work together, there can
be no better opportunity for true system integration.
And with SCS Extrude, Granco Clark’s exclusive
system control software, the performance of
the entire system is monitored in real time and
maximized minute-to-minute.

9. Granco Clark’s Automated
Profile Handling Equipment helps
maintain throughput and profile surface quality.
Profiles are transferred smoothly from the runout
conveyor to the cooling belt table, where heat
dissipates easily. A series of low-temperature belts
transports profiles through the stretching cycle and
beyond. As the stretcher tailhead repositions itself
to stretch extrusions of various lengths, belts extend
or retract as needed.
The saw-feed loading-belt system automatically
receives extrusions from the stretcher, batches them,
and feeds them into the saw to maximize throughput
and minimize manpower requirements.

10. Granco Clark Pullers deliver
even, twist-free profiles and reduce scrap by
applying just the right amount of tension as the
profile emerges from the die. The Granco Clark
Double Puller features two puller heads on the same
track, which allows it to seek the die mark and cut
profiles on the fly. Twin, twin/twin, and single puller
configurations provide increased productivity in a
wide range of applications.

Technologies that work—and work together.

The Granco Clark Extrusion Cutoff Saw is
a large-capacity, high-performance saw that delivers
extremely close tolerances and an excellent surface
finish. The saw features a drop-down arbor design to
eliminate backrake for improved cut quality. As an
extrusion batch is fed through the saw, the saw gauge
stop lowers automatically and the ends of the profiles
line up against it. The saw hood lowers to clamp the
extrusions and the blade moves across the table to
cut the profiles.

12. Granco Clark’s Automatic Profile Stacking
and Destacking Systems allow profiles to move from
cutting through aging without any manual handling.
This translates into higher-quality profiles and higher
throughput, while reducing labor requirements.
Automated spacer distribution and collection
systems pick up the spacers and places them in
position. The stacker picks up the ends of the
spacers and carries the profiles to the aging rack.
After aging, the destacker unloads one layer of profile
at a time onto a conveyor, and the spacers are released
and collected for another cycle.
13. Granco Clark Age and Anneal Ovens
feature high-volume air systems that bring loads to
temperature quickly and uniformly. This maximizes
throughput and ensures high-quality profiles of
uniform hardness. Several models are available,
including the double-end-flow age oven that features
dual burners and fans that supply air to each end
of the chamber, speeding up the process and
improving temperature uniformity.

14. The Granco Clark Precision
Finish Saw delivers an incredible degree
of cutting accuracy. A unique dual
clamping system holds profiles fast and
prevents guillotining. The highly efficient
hitch-feed system uses positive pressure
to move profiles forward after cutting,
improving cycle times and preventing
backrake on the blade return. A pull-out
cabinet cover makes blade changes
and maintenance easy.
SCSExtrude Software Control System.
Productivity is heavily impacted by how well
these technologies work together to keep the
process moving—creating and finishing high
quality profiles with the right degree of
accuracy. That’s maximum throughput. Or
to put it another way—profitability.
Granco Clark has just the product to
help make that happen: SCSExtrude. It’s
a complete process-control software system
that handles production scheduling, data
collection, diagnostics, and the loading
of profile parameters.
