Silfax Group
France TBC
SILFAX Group’s hydroforming machine
model SHD4N was designed in 2007 and
prototyped in 2008, and more than five
machines have already been sold around
the world, to cope with the growth in the
exhaust gas recirculation (EGR) business.
SHD4N can handle tube diameters from
12 to 50mm, and lengths from 200 to
800mm. The fully electric machine produces
a hydroforming pressure of 350 bar.
The machine’s tooling features a quick tool
tightening system and an adaptive concept,
with a common framework, removable and
independent internal parts, and ‘multi-waves
group’ within the same tool. Changeover
takes five minutes for a complete set, or 15
minutes for internal parts.
SHD4N is suited to multiple uses as a
means of connecting all of the components
of an exhaust gas circulation system.
From the exhaust gas sampling point (eg
manifold or cylinder head), through the
EGR cooler and the EGR valve to the
intake tract, the cramped conditions in the
engine compartment often call for complex
connections with flexible pipes.
Some EGR lines require cooling by means
of a (partial) water jacket. This also facilitates
the cooling of the recirculated exhaust gas
without seriously compromising installation
space. Under certain conditions, it may
even be possible to dispense with an EGR
cooler altogether.
SHD4N also has applications in oil return
lines, secondary air pipes, compensators
and fuel filler pipes.

YLM & J&S Machine
USA 3101
YLM & J&S Machine will be displaying the
newly released CNC38 at Fabtech, a 1-½″
capacity all electric rotary bender working
with an autoloader.
This quiet, fast machine utilises the
technologies developed from experience
with the servo motor technology of earlier
models. The control is capable of importing
data in various forms, connecting to a
network, displaying the part in 3D, and
showing a bending simulation of the
programmed part.
The second newly released machine to
be shown will be the CMP 16. The CMP
16 pulls material from a coil, straightens,
endforms, bends and cuts, completing
multiple processes in one operation. This
model was developed for fast accurate work
in the copper and aluminium bending fields.
Tre C & J&S Machine will be displaying
the CR138RIMW – a Windows-based CNC
roll bender with 2½″ capacity. The control
is capable of importing dxf formatted files,
connecting to a network, displaying the part
as it is programmed, and showing stored
profile shapes. The 160 roller rotation
speeds and 500 roller location speeds are
servo controlled for precision settings and
automatic calculation of the 36 radii per part
program.
Programs can be stored for recall, which
ensures repeatable parts with the desired
blending actions when changing from one
radius to another or going from a straight
to a radius. Automatic encoder positioning
with photo eye part detection coupled with
the usage of the bending archives facilitates
quick setups and optimum cycle times.
