Custom Components for Defense Industry

Custom Components for the Defense Industry

The equipment used in the defense and homeland security sector must be of the highest quality and constantly upgraded to meet the latest technology at every turn. Depending on the machine or application at hand, the parts or components involved might call for common or rare materials.

For defense contract machining, strong materials with high thresholds for temperature and pressure are essential to keep equipment parts running for as long as possible without breaking down. As such, contractors in the field of precision manufacturing for homeland security utilize everything from sheet absorbers and dielectric materials for a vast range of customized machinery.

Sheet Absorbers

When it comes to CNC machining for the defense industry, materials with absorption capabilities are vital. With materials of the flexible foam variety, stray radiofrequencies can be absorbed and therefore prevented from causing disruptions within a given working arsenal. Examples of such absorbers include the following:

  • Broadband carbon/foam flexible radar absorbers. For the needs of broadband applications, radar absorbers of the carbon and foam varieties are used for machining in the defense industry. At AMI, we work with contractors who utilize such materials on a regular basis.
  • Reticulated foam absorber sheets. For the absorption of microwave frequencies, contractors in the defense industry often use absorber sheets made of urethane foam with gradient lossy coating, the likes of which are applied in machines that we handle with our clients.
  • Lossy carbon-loaded flexible foam microwave absorber sheets. For the purpose of attenuating surface currents, isolating components and absorbing wandering currents of radiofrequency energy, microwave absorber sheets of the flexible foam variety are vital tools for defense contract machining.
  • Flexible, tuned frequency magnetic microwave absorbers. The vast majority of stray radiofrequency energy within a given range can be absorbed with magnetic microwave sheet material, and defense industry contractors often approach us for CNC machining projects of this scope and aptitude.
  • C-RAM millimeter waves. Sheets and materials of the plastic foam and elastomeric varieties are known for offering the highest grade performance across the defense industry, and the materials come in a range of thicknesses and frequencies to accommodate numerous applications.
  • 3M 467MP pressure sensitive adhesive option for absorber sheets. Custom components for the defense industry sometimes require a more pressure sensitive material, which can be helpful in some of the more heavy-duty applications that our clients often utilize.

Precision manufacturing for homeland security must be executed with expertise and care to ensure utmost safety, security and efficiency. At American Micro Industries, we've helped numerous clients develop custom components for homeland security and defense machining with the most powerful absorber sheets on the market.

Dielectric Materials

A vast range of custom components for the defense industry rely on low loss dielectric materials that don't conduct electricity, but they function to polarize it. This way, the material can interact with a field of electricity without collapsing into the field. Examples of such materials include the following:

Dielectric Materials for Defense Industry
  • Plastic stock with adjusted dielectric constant. For a vast range of radiofrequency and microwave applications, cross-linked plastic materials with adjusted dielectric stock are used for CNC machining for homeland security, as often specified by clients from within the industry.
  • Low dielectric constant, low loss sheet stock. For applications that involve antennas, waveguides and coaxial supports, materials with low loss tangents, densities and dielectric constants are most optimal, and are therefore commonly used in custom components for homeland security.
  • Very low loss polystyrene sheet and rod stock. Cross-linked polystyrene materials are known for their stability in high temperatures, which makes such materials ideal for antenna insulators and microwave lenses, the likes of which are often custom made for defense industry clients.
  • Lightweight artificial dielectric material. Lightweight dielectric material made from glass microspheres and epoxy plastic resin are particularly suitable for antenna parts, microwave lenses and aircraft applications, and therefore commonly factor into precision manufacturing in the defense industry.
  • Low dielectric constant, low loss structural foam. With their ability to withstand extreme levels of heat, structural foams with low dielectric constants are important for a range of components that are used every day for the purpose of CNC machining for defense industry applications.
  • Flexible, low loss foam. Made of closed-cell foam, flexible materials with low levels of water absorption are optimal for the purpose of weatherproof radiofrequency transparent radomes, as well as for dielectric substrates, which are often utilized by defense industry contractors.
  • Flexible, weatherproof low-signature plastic fabric. Materials made with thin nylon fabric and sealed with elastomeric binders are ideal for the covering of radar absorbers, because the surfaces can easily be cleaned, and the material is waterproof, flexible and UV-resistant.
  • Rigid foam-in-place liquid polyurethane. Intended for cavity filling in electronic and microwave components, liquid polyurethane is vital for operators of waveguides, radomes, and instrumental housing, yet the material can be sensitive to moisture and must therefore be handled and packaged with care by professionals. This is not available in CA, due to Prop 65.
  • Lightweight syntactic foam. Suitable for curing at reasonably hot temperatures, lightweight syntactic foam is good for encapsulating components, and is often useful for precision manufacturing for defense industry components, as well as for custom components for homeland security projects.
  • Cyanate ester syntactic foams. Cyanate ester syntactic materials are generally packed in complex shapes, such as cured and pre-molded sheet rock, but with a wet sand-like consistency, which makes the material suitable for select applications that are sometime used by our clients.

Precision manufacturing for defense industry applications is an area that American Micro Industries covers with a vast range of our clients, whether the project involves low loss structural foam, low-signature plastic fabric, or various other types of dielectric materials suited for defense contract machining.

Honeycomb

When it comes to projects that involve custom components for the defense industry, various clients of American Micro Industries come to us with projects in which honeycomb absorbers are one of the needed components. As it stands, a few different types of honeycombs are applicable for defense contract machining.

Honeycomb for the Defense Industry
  • Broadband honeycomb absorbers. Honeycomb products that are made of glass/phenolic or Nomex/phenolic mixtures, and that are given proprietary lossy coatings, are suitable for covers, fairings and leading edges on aircrafts, and are therefore optimal for custom projects for clients in the defense industry.
  • High power honeycomb pyramidal absorbers. Pyramidal absorbers consisting of treated plastic honeycomb are ideal for various parts that are used in projects by defense industry contractors, and have often been used in large custom projects for clients of American Micro Industries.

CNC machining for homeland security often calls for a variety of heavy-duty materials that can withstand intense amounts of heat and stress and ultimately remain in impeccable working condition for years on end. Whatever the demands of your operation might be, American Micro Industries has handled custom defense and homeland security projects across the spectrum for many years.
