From large, medium, to small pierce equipment MLS Systems can do it all. MLS Systems can provide multi-station trim/pierce and transfer
stations or single station pierce machines as well as sub stations tooling packages and
retrofits of your existing equipment.
The large multi station trim & pierce system with
transfer shown above,
was designed to handle large capacity liners at a 15 second
cycle time.
This custom refrigerator cabinet liner pierce system included a flat
belt in-feed conveyor from an in-line thermoforming system. The
cabinet liner scrap flanges were trimmed in a box shear before holes
of various sizes and shapes were pierced into the liner body sides
and ends. This system also featured a gantry style overhead transfer
which contained carriages with redundant vacuum systems and
capability to rotate the liners 90-degrees during transfer.
This refrigerator liner pierce system was designed
to pierce large capacity Side by Side liners with a 12 second cycle
time. Liners are loaded in the front of the machine, pierced and
exit out the back.
This small
liner pierce unit was designed for small capacity refrigerators.
Liners were loaded and unloaded from the front of the machine which
performed the pierce and trim operation in 10.5 seconds.
Special
contoured dies and punch tools are no problem for MLS Systems to
provide. To reduce your equipment costs, our designers utilize
standard punches and dies wherever possible. In cases where this is
not possible special tooling like that pictured is used.
View of Lock Out Tags and Interlocked Guarding. Special bilingual tags like the one
above in Spanish and English, can be provided. We can supply equipment and tags in accordance with your
facilities lock out tag out procedures.
The view
above, shows how the liner locating tooling on the liner support mandrel has
been contoured to support the liner during the trimming and piercing operation.
This view also shows a liner flange trimming tool which nipped profiles into the
corner of the liner as the holes in the liner body were pierced.
Your liner pierce machine can be equipped with light curtains, palm switches, and interlocked
guards for operator safety as well as powered or non-powered in-feed and exit conveyors to
ease operator load and unload.
If your production requirements include automatic liner loading and unloading,
this can also be provided in a variety of methods. At left, a platen mounted transfer
has been incorporated.
MLS Systems utilizes the latest in 3D modeling software in the design of our equipment
which reduces mistakes to intricate tooling components found on most liner pierce projects.

This machine is used for piercing refrigerator door panels. The
hydraulic power unit was mounted on a mezzanine above the dual
presses to conserve floor space.
This wire basket trimmer is angled for ease of operator load and
unload. It also has the capability to trim multiple basket profiles
with a 15 minute tool change. Trimming operation takes less than 6
seconds to trim 38 places on the basket perimeter.
The dual press configuration runs two different models of
doors but share PLC and hydraulic power unit.
MLS Systems has built many basket trimmers like the one
pictured. Banks of precision guided blades are indexed in
sequence to trim the top perimeter of wire baskets.
MLS Systems has built many C-frame notch and pierce
machines like the one pictured. Panels can be manually placed or
automatically indexed under the C-frame heads for the required
notching and piercing operations.
This hydraulically actuated C-frame pierce machine was used
to pierce a pattern of round and square holes into tube material for
an automotive customer.
