PPI was founded on composite material fabrication. Composite curing and bonding is accomplished in an autoclave measuring 6 ft. in diameter and 18 ft long, controlled to a maximum of 650 degrees Fahrenheit and 250 psi. Composite curing is also accomplished in several large batch ovens measuring up to 10 ft. x 8 ft. x 10 ft. Precision lay-up is accomplished by a computer controlled composite ply cutting machine.

Sheet Metal

PPI manufactures a wide variety of sheet metal parts and assemblies including pressure bulkheads, pressure doors, metal bonded assemblies, aluminum honeycomb sandwich panels, and electronic component enclosures.

Metal Bond

PPI performs Metal Bonding of "metal-to-metal" and "metal-to-core" on flat panels and shaped structures.
