Aerospace metal finishing services including anodizing, chemfilm, passivation, shot peening, and painting

You can contract aerospace metal finishing services from National Aerospace Processing (NAP) by following a straightforward, quality-driven process backed by full Nadcap accreditation and an AC7004 aerospace quality system. After connecting with our team, you can begin your project by sharing your drawings, specifications, and finishing requirements. NAP will review your project, confirm capability, and provide a detailed RFQ that includes pricing, lead times, and any tooling or masking considerations. For new programs, NAP can support qualification requirements you specify, including supplying process certifications and documentation needed for your internal approval process.

To ensure the level of quality control you require, your purchase order can call out the exact standards and documentation you expect. NAP integrates these requirements into production through disciplined process control and traceability. Common items customers include are:

• Nadcap-accredited processes for anodize, ChemFilm, passivation, paint, and shot peen
• Referenced specs (MIL, AMS, or OEM) and required coating classes
• Certificates of Conformance and process certs with each shipment
• Qualification or First Article requirements defined by your organization
• Testing expectations, such as coating thickness, adhesion, or other finish-specific checks
• Right of access for audits or source inspections

With accredited processes, consistent turnaround, and a robust aerospace quality framework, NAP delivers reliable, compliant finishing for demanding aerospace programs.

NAP ensures Nadcap AC7004-compliant quality by maintaining a disciplined aerospace quality system that governs every stage of its surface treatment processes. AC7004 is Nadcap’s Aerospace Quality System (AQS) standard, and NAP meets its requirements through documented procedures, controlled processes, trained personnel, and continuous monitoring of chemical processing and shot peen operations.

To uphold AC7004 compliance, NAP uses:

• Formal process documentation and work instructions for every finishing operation
• Defined control plans for chemical processing, including routine bath analysis and solution monitoring
• Qualified operators and ongoing training aligned with Nadcap and internal requirements
• Traceability from receiving through processing, inspection, and certification
• Internal audits and corrective action systems to ensure continuous conformity
• Calibration and maintenance programs for all equipment used in anodize, ChemFilm, passivation, paint, and shot peen
• Nadcap audits that validate compliance and ensure each accredited process stays within scope

Together, these elements create a controlled, repeatable, and fully auditable environment that meets the strict expectations of Nadcap AC7004 and supports reliable aerospace-grade surface finishing.

NAP performs surface preparation and CARC painting within its Nadcap AC7004-accredited Aerospace Quality System, ensuring each step is controlled, documented, and fully traceable. These services are also supported by NAP’s Nadcap Chemical Processing accreditation for Paint – AC7108/1, which covers aerospace-grade primer and topcoat applications, including CARC systems.

NAP’s surface prep and CARC-related capabilities include:

• Surface preparation such as cleaning, degreasing, and substrate preparation required before coating
• Application of aerospace wet paint systems, including primers and topcoats meeting military and commercial specifications
• CARC (Chemical Agent Resistant Coating) painting, applied in controlled spray environments
• Curing and finishing operations using dedicated equipment designed for consistent, specification-driven results
• Process control and documentation performed under Nadcap AC7004, ensuring compliance with customer, MIL, and AMS coating requirements

With the combined coverage of AC7004 and AC7108/1, NAP’s surface prep and CARC painting services are delivered within a fully audited aerospace quality framework appropriate for defense, military, and commercial aviation programs.

NAP uses NADCAP-accredited processes and follows strict industry standards, like AMS2471 and MIL-PRF-8625, to ensure that our precision anodizing and coating services meet or exceed aerospace OEM specifications. By adhering to these globally recognized standards and ensuring that everything we do goes through stringent quality control, we deliver compliant finishes that can hold up to even the most demanding applications.
