Which aerospace standards and certifications does Neway comply with for superalloy machining?
Neway's capability to machine superalloy components for the aerospace industry is underpinned by a rigorous adherence to internationally recognized quality and management system standards. Our compliance is not merely about certification documents; it is an integral part of our manufacturing culture, ensuring traceability, repeatability, and the highest levels of part integrity required for flight-critical applications.
Foundational Quality Management System: AS9100D
The cornerstone of our aerospace manufacturing is compliance with the AS9100D quality management system. This is the aerospace industry's version of ISO 9001, with additional, stringent requirements specific to aviation, space, and defense. AS9100D certification validates that Neway has robust processes for:
Risk Management: Proactive identification and mitigation of risks throughout the manufacturing process.
Project and Configuration Management: Ensuring that all part revisions, engineering changes, and documentation are strictly controlled.
Traceability: Maintaining full material traceability from raw material mill certs to the final shipped component, which is non-negotiable for superalloys used in critical components.
Supplier Management: Vetting and controlling our own supply chain for raw materials and subcontracted services.
Nadcap Accreditation for Special Processes
While AS9100D covers the overall quality system, the National Aerospace and Defense Contractors Accreditation Program (Nadcap) provides the industry-managed accreditation for special processes. For superalloy machining, the most critical Nadcap accreditations we comply with include:
Nadcap for Heat Treating (HT): Superalloys derive their properties from precise thermal cycles. Nadcap HT accreditation audits our furnace equipment, temperature uniformity surveys, pyrometer calibration, and operator certification to ensure every Heat Treatment process for alloys like Inconel 718 meets strict industry standards like AMS 2750 for pyrometry.
Nadcap for Non-Destructive Testing (NDT): Ensuring the integrity of machined superalloy parts is paramount. We utilize Nadcap-accredited NDT methods such as Fluorescent Penetrant Inspection (FPI) per AMS 2644 and Ultrasonic Testing to detect surface and sub-surface defects that could compromise component life.
Nadcap for Materials Testing Laboratories: This accredits our in-house or partner labs for conducting mechanical testing and metallurgical analysis to verify material properties and conformance to specifications.
Compliance with Key Aerospace Material Specifications (AMS)
Our Superalloy CNC Machining Service is performed in strict accordance with Aerospace Material Specifications (AMS). This ensures the material chemistry, heat treatment, and resulting mechanical properties are certified to meet the demands of gas turbine engines and airframe components. Key standards we routinely work to include:
Heat Treatment Standards: Such as AMS 2750 (Pyrometry) and specific heat treat specs for alloys (e.g., AMS 5662 for Inconel 718).
Material Specifications: Defining the required composition and properties of the superalloy billets we start with.
Process Specifications: Covering everything from machining guidelines to cleaning and inspection requirements.
Customer-Specific Requirements and OFP
Beyond these industry standards, we are adept at meeting the exacting requirements of major aerospace OEMs (Original Equipment Manufacturers) and primes. This often involves compliance with their proprietary specifications and a thorough review process. A critical output of this compliance is the comprehensive First Article Inspection Report (FAIR) per AS9102, which provides objective evidence that every aspect of the manufacturing process—from material certification and Precision Machining to final heat treatment and NDT—has produced a part that meets all design requirements.
