🛡️ Quality Control Process ( NADCAP / AS9100 / ISO 9001 Compliance)

1️⃣ Raw Material Control

🔍 Key Control Points (KCP): Material Traceability / Certificate of Conformance

• All stainless steel, titanium alloys, and superalloys are procured from ASL-listed (Approved Supplier List) sources.
• Each batch must be accompanied by a Mill Test Report (MTR) with full heat number traceability.
• Critical materials comply with AMS standards, such as:

  Inconel 718 – AMS 5662

  Ti-6Al-4V – AMS 4928
• Incoming inspections include chemical and mechanical property re-verification through sample testing.（if applicable）

2️⃣ Process Control

🔍 KCP: Process Validation / Work Instruction / Special Process Control

• All operations follow validated Process Flow Charts (PFC) and documented Work Instructions (WI).
• Toolpaths are simulated using CAM software (e.g., Mastercam, NX) before execution.
• Special processes (welding, heat treatment, coating) are performed by NADCAP-accredited partners, and each process has a qualification record.

3️⃣ First Article & In-Process Inspection

🔍 KCP: FAI per AS9102 / In-Process Control Plan

• First Article Inspection is conducted in accordance with AS9102 Rev. B, covering all drawing dimensions and specifications.
• In-process checks include SPC (Statistical Process Control) for CTQ (Critical to Quality) features.
• All measuring instruments (e.g., calipers, CMMs, microscopes) are calibrated, have unique IDs, and are traceable to national standards.

4️⃣ Functional & Performance Testing

🔍 KCP: Test Plan / Functional Qualification / Acceptance Criteria

• If applicable, leakage, stiffness, and fitment tests are performed to validate performance.
• Every production batch is verified against design specification using predefined test methods.
• A formal Test Record is issued per part, clearly showing conformance with acceptance criteria.

5️⃣ Special Process Management (If Applicable)

🔍 KCP: NADCAP Accreditation / Process Certification

• All special processes (welding, thermal coating, etc.) are performed by NADCAP-certified suppliers.
• Each step is supported by a Process Approval Record, and only qualified, certified operators are assigned.

6️⃣ Final Inspection

🔍 KCP: Dimensional Inspection / Surface Quality / Conformance Documentation

• A complete dimensional inspection is conducted using CMMs.
• Surface roughness is checked to ensure Ra ≤ 0.8 μm; visual and optical inspection is performed on welds and critical surfaces.
• Certificate of Conformance (COC) and Final Inspection Checklist are completed prior to delivery.

7️⃣ Documentation & Traceability

🔍 KCP: Document Control / Lot Traceability / Data Retention

• Each cylinder block is traceable by a unique serial number, and accompanied by Process Router, QC Reports, Test Records, and Material Certificates.
• All quality records are retained for a minimum of 10 years, as required by AS9100 Clause 7.5.
• Upon request, a full Quality Assurance Package (QAP) is provided, including FAI, SPC charts, and test data.
