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

1️⃣Raw Material Control

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

• All raw materials (stainless steel, titanium alloys, superalloys) are sourced from approved suppliers listed in the ASL (Approved Supplier List).
• Each batch must be accompanied by a Mill Test Report (MTR) with clear heat number traceability.
• Critical materials conform to AMS standards, such as AMS 5662 for Inconel 718, AMS 4928 for Ti-6Al-4V.
• Incoming inspection includes material verification and sampling re-tests for chemical and mechanical properties.(If Applicable)

2️⃣ Process Control

KCP: Process Validation / Work Instruction / Special Process Control

• All operations are conducted under validated Process Flow Charts (PFC) and documented Work Instructions (WI).
• Toolpaths are verified through simulation software (e.g., Mastercam, NX) before execution.
• Special processes (welding, heat treatment, surface treatment) are outsourced to NADCAP-accredited suppliers, and each process has a qualification record.

3️⃣ First Article & In-Process Inspection

KCP: FAI per AS9102 / In-Process Control Plan

• First Article Inspection (FAI) is performed according to AS9102 Rev. B, covering all drawing and specification dimensions.
• In-process inspections include Statistical Process Control (SPC) on CTQs (Critical To Quality features).
• All measuring equipment (calipers, CMMs, microscopes) are calibrated and traceable to national standards, with dedicated IDs.

4️⃣ Functional & Performance Testing

KCP: Test Plan / Functional Qualification / Acceptance Criteria

• Atomization testing is performed using laser diffraction to measure droplet size distribution and spray uniformity.
• Flow rate and spray angle testing is conducted on each production batch to meet design specifications.
• A formal Test Record is maintained for each nozzle, documenting results against pre-defined acceptance criteria.

5️⃣ Special Process Management (If Applicable)

KCP: NADCAP Accreditation / Process Certification

• If required (e.g., for welding or thermal coating), all special processes are handled by NADCAP-certified partners.
• Each special process step is documented with a Process Approval Record, and certified operators are assigned with valid qualifications.

6️⃣ Final Inspection

 KCP: Dimensional Inspection / Surface Quality / Conformance Documentation

• A full dimensional inspection is conducted using Coordinate Measuring Machines (CMMs).
• Surface roughness is checked to ensure Ra ≤ 0.8; nozzle holes and weld seams are inspected visually and optically.
• A Certificate of Conformance (COC) and Final Inspection Checklist are completed before shipment.

7️⃣ Documentation & Traceability

 KCP: Document Control / Lot Traceability / Data Retention

• Each nozzle is traceable with a unique serial number and complete Process Router + QC Reports + Test Records + Material Certificates.
• All quality records are retained for a minimum of 10 years, in accordance with AS9100 Clause 7.5 on documented information.
• Upon request, a full Quality Assurance Package (QAP) is provided, including FAI, SPC charts, and test results.

FAQ

Q1: Can you customize the nozzle structure and performance parameters according to customer drawings?
A1: Yes, we offer full customization based on customer drawings. Spray hole diameter, spray angle, flow rate, and droplet size can be tailored as required. Sample fabrication and performance testing reports are available.

Q2: Do the products come with material and inspection certificates?
A2: Yes. Each nozzle can be delivered with a Material Test Report (MTR), CMM dimensional inspection report, atomization and flow test data, and a Certificate of Conformance (COC). FAI reports and full traceability documentation are available upon request.

Q3: Do you support small batch prototyping? What is the typical lead time?
A3: Yes, we support small batch and prototype orders. Standard lead time is 7–15 working days depending on design complexity and any required surface treatments. Expedited delivery is available upon request.
