Affordable Alternate to Original Equipment Manufacturing (OEM)

Streamlining the Source Approval Process for Defense Readiness

Parts Life Inc. helps defense customers secure manufacturing approval for critical components through our Source Approval Request (SAR) development services. The SAR process ensures that a new supplier can meet stringent quality and performance requirements before producing a part.

Our SAR process begins with reverse engineering and data package development, ensuring that each component meets all required specifications. Our engineers utilize advanced 3D modeling and precision measurement tools to create manufacturing-ready technical data, even when OEM specifications are unavailable.

Throughout the SAR development period, we maintain regular communication with ESAs via bi-weekly or monthly updates, ensuring transparency and addressing concerns proactively. Our expertise in Manufacturer Qualification Requirements (MQRs) across the Department of Defense (DoD) enables us to efficiently navigate the approval process.Once approved, the SAR transitions into full-scale production, ensuring a reliable, long-term supply of critical parts. Parts Life Inc. provides a seamless, turnkey solution for customers seeking to maintain operational readiness with approved, high-quality component manufacturing.
