Custom Molded Masks For Industrial
Over the years we have helped various industrial coaters—Painting, Powder Coating, E-Coating, Anodizing and Plating---in dealing with difficult masking needs.
In many cases a simple mask is needed and can be
accomplished with tape or die cut rubber sheeting with pressure sensitive tape.
Our niche is working with our customers to mask more difficult areas of parts
where coatings are not wanted and using die cut masks are impractical and using
tape is very time-consuming and not consistent. Molding rubber shapes to provide
the necessary mask along with tethers or handles
allows for easy
operator insertion and removal which increases productivity
and profitability for your coating job.
The key to deciding when to turn to custom-molded
masks is their suitability for a particular application. Coatings deposit on every available surface during application,
including places where they’re not wanted. Removing unwanted coatings takes time
and labor, and slows production. Any time operators have to do secondary
operations after a finishing step, like removing the coating from threaded studs
or other surfaces, a custom-molded masking plug or masking cap would make a huge impact on
Although custom-molded masks aren’t always the
best solution because of engineering costs, they can resolve difficult coating
issues like poor finish quality, poor consistency, slow mask application and
removal, and poor production line productivity. Custom-molded masks make sense
when you need to protect unusual surfaces and openings, and they do so while
providing excellent results in very hostile finishing environments. They differ
from die-cut tape masks in several key ways:
Custom-molded masks protect parts in difficult
environments. Custom-molded masks can mask almost any surface, aperture, or
combination of the two. No application is really beyond them. Masks can be used
for Painting, Plating, Powder Coating, E-Coating and Anodizing. Materials can be
selected for the operating environment including high temperature conditions.
- Masking Caps mask plain or threaded
studs, tube ends and slotted holes. They can be used as a
parallel plug to mask thru holes. Washer Caps
provide a concentric mask around a stud. Terminal
Caps are ideal for masking grounding tabs.
- Masking Plugs mask threaded or
non-threaded holes and provide excellent sealing power.
Plugs can be solid or hollow, tapered or straight.
Hollow Plugs provide more flexibility than solid
plus, are easier to insert and are less costly than
traditional tapered plugs. Plugs with Handles
allow for easier insertion and removal and can be solid or
hollow. Dual Purpose Plugs can have different size or
shaped ends to accommodate more then one opening.
Flanged Pull Plugs masks off chamfer, first
thread and last thread in through holes. Washer Pull Plugs
make the hole and earthing area or countersink area.
- Masking Sheeting can be provided in
sheet or die cut form and are used for gaskets, pads,
strips, washer and seal.
Custom-molded masks can be quickly installed
and removed. When operators are forced to manually create a mask from tape,
apply multiple masks, or engage in a time-consuming alignment process, it’s
probable that a custom-molded mask would speed up the process and quickly pay
for itself. Masking plugs can be made with handles and masking caps with tethers
to make insertion and removal quicker and easier.
Properly designed molded masks are
self-aligning and can mask multiple surfaces with one insertion. Because
they're molded in three dimensions, these masks can be ergonomically designed
with flanged handles, rings, tethers or other aids. Also masking caps and
masking plugs can be color coded for easy identification as to the area they are
supposed to mask.
Custom-molded masks can be reused. Advances in rubber compounding allow J.J. Short Associates, Inc. to produce
molded masks with precisely the right combination of flexibility and durability.
Molded rubber masks can handle applications where flexibility is called for, yet
survive multiple trips through the coating cycles.
Operators on production lines can be innovative,
producing some pretty ingenuous workarounds for coating problems. The problem
with that is, a series of manual steps involving operators and cutting tools can
add up, and these things tend to creep up so quietly that companies don't even
notice how much time, and therefore money is being wasted.
Working with you and your team we ask for
information on how the part hangs on the rack or about the space constraints.
A mask that can’t be inserted easily, defeats its own purpose. Because
everybody’s process is different, we will gladly will visit your shop to look
for areas that are causing problems.
Custom-molded masks can solve production problems
and often outperform die-cut tape masks in even simple applications where
alignment or insertion and removal speeds are important. In difficult
environments, molded masks are often the only reasonable choice.
The downside is the initial tooling costs. Still,
given the cost structure driving today’s production environments—in which
consistent quality is paramount and productivity an imperative—custom-molded
masks can make a huge difference and pay back the initial up-front costs very
