“When General Motors Corp.
selected L.K., as their supplier for
new 3000 ton Machines, they did
so as a partner to L.K. offering
their considerable experience and
highly developed specifications,
while L.K. offered the latest in die
casting machine capability and
technology together with considerable
economies of scale from a
producer of 1,800 die casting
machines per year. L.K.’s global
technical team worked continuously
with the Bedford team to
produce a die casting machine that
meets the needs and specifications
of General Motors. Surprisingly,
it wasn't the big items that got the
most attention, as L.K.’s closing
and shot ends are designed for
performance, but it was the small
items that got the most attention,
from electrical and hydraulic
components, to fittings and connectors.
In the end, all areas of
the machine design were closely
examined, resulting in a machine
design that exceeds the most comprehensive
machine specifications available anywhere.
The first machine, and the ones to
follow feature L.K.’s latest real time
shot system technology with
the capability to produce transmission
cases and engine blocks. Each
machine is equipped with L.K.’s
new shot control and monitoring
system, CAST Advantage™, with
options for both open and closed loop
control. The CAST Advantage
system also provides advanced shot
system diagnostic capabilities as
well as our NEW “Dynamic
Force™” profile feature to capture
shot force applied to the metal at
the end of shot. Together with our
ultra-fast end-of-shot deceleration,
users can monitor the combined
static and dynamic components of
the end-of-shot force and react to
changes in the process that produce
undesirable flash.
These machines also feature quick
die change capabilities such as
quick die clamps to secure the dies
to the platens, cylinders to assist in
cover die removal, precision die
carriers to simplify die changes,and mobile carriers to manage die
hoses and cables. To complete the
die casting cell, a modular post
processing cell was designed to
minimize labor by automating
inspection, overflow and runner
removal, part marking, inspection,
and rack loading.
The entire system is controlled by
an Allen-Bradley Guard Logix
controller, equipped with two
Panel View touch screen HMI’s.
From the HMI’s, the operator can
view the
status of all
equipment
in the system,
including
the
extract and
spray robots,
as
well as the
operational
settings and status of the die casting
machine, While this is a
large, comprehensive die casting
machine control system, considerable
effort was made to ensure
that start-up and recovery from
stoppages was simplified so that operators could initiate a new
cycle with minimal effort from
the main HMI.
To complete the delivery, L.K.
has deployed a site Program
Manager, and Lead Project
Engineer both residing in Bedford,
IN. This team, along with
other L.K. global team members.,
will provide onsite support
during the machines installation
and commissioning.
