The INF-2 is a new concept pail packer, designed by Gimax, for
the process of packing wire into drums.
The INF-2 is a ‘fully packaged system’ in the sense that the only
separate entity from the main body is the driven pay-off –
both the dancer and the electrical control cabinet have been
incorporated into the main body resulting in an enormous
reduction in space occupancy (and height), and subsequently
in costs for the end user.
The unit does not follow the traditional method of raising and
lowering the drum during the packing process. The drum and
flyer both rotate, but the INF-2 makes use of an innovative
process in which the front portion of the unit itself slowly rises
while the flyer is layering the wire within the drum. The entire
flyer assembly is of totally new design and concept, a different
philosophy to traditional methods.
The pail packer can handle various drum types (round,
hexagonal, octagonal) and various sizes ranging from small
100kg up to the traditional 350kg drums of MIG wire, and also
up to the large 500kg drums as the unit can handle drums
with or without a central core.
The unit is already set up as standard with a base that can handle
both round and square drums. Size changeover is minimal.
The unit is equipped with wire straighteners, capstan and
vibrator to settle the wire in the drum and comes complete
with an operator platform which raises and lowers with the
machine so that all parts of the unit are easily accessible for
maintenance and for threading the wire through the system.
The INF-2 can also be equipped with an optional video-cam
system that allows the operator to check the inside of the
drum as well as other parts of the line while the unit is in
operation.

Durable welds in just seconds
New concept for packing wire into drums
The capabilities of the SonoWeld® 1600
and dual head spot welders were the
focus of Sonobond Ultrasonics’ display
at the 2014 Battery Show in Detroit,
Michigan, USA.
“Our units require no consumables and
use lower vibration amplitude than
competitors’
ultrasonic
equipment
to weld foils as thin as seven microns
without tearing,” said vice president
Melissa Alleman.
“Our dual head spot welder is the first
ultrasonic welder that can join up to 100
layers of copper or aluminium foil in just
one pulse. Both machines provide a fast,
efficient, environmentally friendly and
cost-effective way to weld multiple layers
and/or delicate foils to tabs or terminals.
They also can accommodate battery pouch
assembly and HV termination welding.”
“The use of batteries in all-electric
and hybrid automobiles, as well as in
advanced utility and renewable energy
storage, medical technology, military
applications and telecommunications is
expanding,” added Ms Alleman.
Sonobond’s spot welders create durable
bonds in a single operation that takes
only seconds and employs no heat,
current, fluxes or filler and produces
no arcs, sparks or fumes. Instead, the
units use Sonobond’s unique, patented
Wedge-Reed
bonding
system
that
combines high vibratory force and low
amplitude coupling.
By utilising sheer mode vibration parallel
to the welding surface, while the line
of force is directly over the parts to be
welded, precise, dependable, solid-state
and highly conductive welds are created
without bending stress or stalling. This
ultrasonic system is also the only one
capable of providing one-pulse welding
of most oxidised and tinned metals
without pre-cleaning.
The SonoWeld® 1600 and dual head spot
welders use outputs of 1,500 and 2,500
watts to weld non-ferrous similar or
dissimilar assemblies, including copper
to aluminium. Both have a power supply
with a built-in microprocessor that
features automatic frequency control,
overload protection, and storage and
recall of up to 250 weld protocols.
The units also have digital displays that
allow weld control to be selected by time,
energy, or distance. Easily removed and
replaceable heat-treated steel taper lock
tips can perform up to 100,000 welds.
Like all Sonobond equipment, the spot
welders require only minimal training for
operation.
To ensure that manufacturers get the
spot welder that is appropriate for their
particular applications and requirements,
Sonobond offers a free ultrasonic
welding viability test. Potential customers
provide their materials to Sonobond for
no-cost, no-obligation sample welds. The
company’s assistance does not end there.
If its equipment is incorporated into the
customer’s production process, service
and technical support is available before,
during and after installation.
