Design
To provide the most effective perforated metal services,
manufacturers consider a number of different factors. First, they
think about what perforated metal pattern(s) might be best for your
application. For example, if designing for an audio application,
manufacturers will consider sound transparency. If you’re seeking
high sound transparency, your perforated metal provider will design
a series of perforations with a large open area. Likewise, if you
seek low sound transparency, they’ll design perforations will a
smaller open area. Other things they will take into consideration
when designing and/or customizing perforated metal products are:
space restrictions, safety standards and regulations, industry
standards and time constraints.
Machinery Used
Wide Punching Press
Wide punching presses offer quick and inexpensive perforation. They
feature a die and one or more punch rows that strike the metal
plate as it moves through the machine. With each strike, it punches
the entire width of the plate. Manufacturers can modify die and
punch row patterns in order to create custom perforated metal
products. Because the machine works so quickly, it is easy to find
stress faults in the perforated part. To rectify this, metal
perforators often use a leveler. This removes stress errors by
flattening the plates. The main drawback of this perforation method
is that is has a high tooling cost.
Sectional XY Axis Punching Press
To perforate using the XY press, sheet metal is secured to the
machine and slowly moved around underneath one to several
stationary single-shaped punching rams, which create a detailed
perforated pattern on the metal as it moves in the direction of the
hole design. This process is long, but patience rewards the metal
worker with complex, precise, decorative perforated sheets and
perforated metal panels. Though both manual and CNC punching
methods have their merits, CNC punching tends to be preferred due
to lower labor costs, higher production speeds and greater process
repeatability. In addition, using CNC equipment, it’s easy to
create custom programming.
Automatic Nibbling Machine
Automatic nibbling machines are quite similar to sectional presses,
in that they work on just one section of plate at a time. Unlike
sectional presses, though, their production, including perforation
tool changes, is automated. They create perforations by nibbling
contours. Automatic nibbling machines offer affordable perforating
and good outer plate finishing. Like all perforating equipment,
they can create custom features related to: strength-to-weight
ratio, open area, hole diameter (measured in mm) and hole size
(measured in mm).
