Engineered Porosity PM Applications

In early applications, porous metal parts solved fuel filter problems. Filters became the best-known applications, but Engineered Porosity developed scores of solutions for a variety of industries.
Engineered Porosity components are ideal for a variety of applications because they:

• Attenuate sound

• Control vacuum or pneumatic signals

• Arrest flame

• Restrict flow

• Protect electronic equipment while allowing it to breathe

• Filter

Customers with applications as diverse as writing instruments, military ammunition, and communication equipment consider Engineered Porosity as an excellent process solution. Engineered Porosity provides designers with a unique opportunity to work with components that allow the flow of vapor but not liquids. Further, the porous medium can operate as a precision orifice, without concern for the blockage that may occur with a single, restrictive opening.

Engineered Porosity components have been used as time delays by coupling the part's resistance with the overall system's volume, creating the equivalent of an electronic resistance-capacitance circuit. Acoustical, pneumatic and vacuum applications utilize Engineered Porosity's ability to control permeability, while electronic applications benefit from porous, water-repellent breathers.

Several industries that utilize the benefits of the Engineered Porosity process:
