Pressure Testing Cast Aluminum
In many different industries,
including the automotive industry, it is required that
a product or casting have a tight seal in order to
ensure a leak free product. The seal may be required
to prevent the intrusion of air / liquid into the
casting or to ensure that a liquid is encapsulated
completely inside. To ensure that a product contains
a tight seal, it may be imperative to perform a
Pressure Testing procedure. At Ramsden Manufacturing,
the use of the “Bubble Test” is employed to ensure
leak free castings. The Bubble Test occurs when a
casting is pressurized with air and then submerged in
a tank of identified liquid, usually water. An
operator examines the submerged casting and looks for
any bubbles that may escape from the casting. This
process is designed to prevent casting defects from
not only reaching a customer but also to prevent any
castings that may contain a casting defect from
reaching any kind of assembly or production line.
