The company’s tube cutting machines
incorporate the ‘dual-blade’ shear and the
‘Kleencut’ supported shear cutting methods.
At this year’s Fabtech in Las Vegas, Haven
will launch a new product. The Haventrak
Flying Shear is the result of a partnership
between Haven and the Universal Controls
Group based in Perrysburg (OH), USA.
Haven has combined its dual-blade shear
cut-off head with the U-Trak precision roller
screw accelerator from Universal Controls
Group.
Haven continues to provide its worldwide
customer base with flexible answers to
tube cutting and end-finishing needs
with an emphasis on service, reliability
and automation. The company also
manufactures machines for precision end
finishing, wire brush deburring, specialised
trimming and parting, measurement and
inspection and automatic tube packaging.

With over 30 years of experience, HC
Starck has an in-depth understanding of
extrusion, metallurgy and processing. The
company is a leader in toll extrusion across
a broad range of materials including copper,
stainless steel, nickel based super-alloys,
titanium, aluminium, superconducting
materials, refractory metals, composites
and numerous alloys.
The company’s 5,000 metric ton extrusion
press and gas fired furnaces, with
temperatures ranging from 260°C to
1,315°C, enable the pre-charging of billets
via a furnace with induction coils for heating
purposes. HC Starck also has the capability
to utilize billets ranging from 6″ up to 17″
and to extrude a wide variety of shapes of
up to 17m in length.
Extruded shapes include forward extruded
rods, tube and pipe with flanges as well
as backward extruded heavy wall pipe. Oil
country tubular products and coiled rod are
just some of the standard products that HC
Starck is able to extrude.
Complimenting its extrusion services, the
company also offers state-of-the-art rotary
forging capabilities. HC Starck’s 220t
rotary forge can produce tapers, step and
other shapes to meet a host of application
needs.

Formitt Metal Labs, a division of Hess
Industries Inc, will showcase custom
spinformed hollow tube shapes and
assembly applications at Fabtech 2008.
In one featured application, the company
supplied to the manufacturer of a line of
hose couplings for bulk material handling
using stamped half-forms welded together.
Ten different size configurations were being
manufactured in aluminium, stainless and
carbon steel. Due to wear, the customer
needed to rebuild all ten dies at a
substantial cost.
Formitt Metal Labs was able to replace
all forming and welding operations for
the ten part configurations with one set of
tube spinforming tooling. As a result, the
quality and appearance of the parts was
improved while the cost of future new dies,
die repairs, and welding processes was
eliminated. Formitt now provides spinformed
production parts to the customer.
A second featured application highlights
a manufacturer of aftermarket motorcycle
muffler shells. The old process stamped
and welded end-cones to the muffler tube,
ground down the weld and then polished
the part. Formitt’s technicians developed a
new manufacturing process that eliminated
the dies, stamped parts and welded end-
cones. The spinforming process improved
the part quality by eliminating the welded
joint and grinding operation, which
enhanced part quality and provided a
smooth finish ready for polishing.
Formitt hollow tube fabricated assemblies
may include the insertion of filtration
elements, heat exchange components,
and catalytic elements. The company’s
hollow tube spinforming prototyping and
production technologies are currently used
in the automotive, HVAC, filtration, and
marine industries, in addition to others.
