NADCAP Accredited Special Process Suppliers in San Bernardino, CA

NADCAP accreditation is granted for a specific special process performed at a specific facility, against a process-specific audit checklist. A San Bernardino supplier is not NADCAP accredited as a company; it is accredited for, for example, vacuum heat treatment of particular alloys, a specific plating chemistry, or penetrant inspection. Each accreditation has a defined scope, and any work outside that scope is not covered even if performed in the same building on adjacent equipment. This is the single most important thing for an aerospace buyer to understand, because the Inland Empire has substantial commercial heat treat, anodizing, and plating capacity serving construction and heavy equipment, but only a narrow slice of that capacity is NADCAP accredited, and that slice is process-specific. A processor might hold NADCAP for one line while running several uncredited commercial lines. The practical consequence is that 'we are NADCAP accredited' is never a complete answer to a sourcing question. You must read the accreditation scope and confirm it covers the exact process, specification, and alloy class your part requires, on the line that will actually run it.

Substantially more rigorous and far more specialized. NADCAP audits are conducted by the Performance Review Institute against detailed checklists derived directly from aerospace prime requirements and industry specifications. A heat-treat audit, for instance, scrutinizes furnace temperature uniformity surveys, system accuracy tests, instrument calibration, and pyrometry compliance with AMS 2750, plus quench control and load practices. A chemical-processing audit examines tank chemistry control, rinse adequacy, and coating thickness verification. These audits go deep into the metallurgical and chemical controls that determine whether a special process actually produces conforming results, which ordinary quality audits do not reach. NADCAP is also merit-based: processors with clean audit histories earn extended accreditation intervals, while findings shorten the cycle, so the audit cadence itself signals performance. For a buyer, this means a NADCAP accreditation, especially a long-standing one with extended intervals, carries more weight than a generic quality certificate, because it is keyed to the precise controls your aerospace part depends on. It is worth asking a San Bernardino processor about its accreditation history and any open findings, not just whether it currently holds the accreditation.

Use eAuditNet, the system maintained by the Performance Review Institute, which lists NADCAP-accredited suppliers along with their specific accreditation scopes. Verify three things for a San Bernardino processor: that the accreditation is current and not lapsed, that the scope covers the exact special process, specification, and alloy class your part requires, and that the accredited site is the actual facility performing your work. Because accreditation is process-specific, scope matching is the critical step; confirming a processor is generally accredited is meaningless if its accreditation is for a different process or material than yours. After accreditation is verified, confirm that the special-process certifications you receive with your parts reference the accredited process and the governing AMS or customer specification. This closes the loop between the accreditation and the actual work performed. The most common failure mode is the coverage gap, where a buyer confirms a supplier is NADCAP accredited but for a different process line than the one running their part, so always tie the verification back to your specific specification rather than to the company name.

No. NADCAP accredits a single special process in depth; it does not certify a complete quality management system, and it does not replace AS9100 or ISO 9001. A NADCAP-accredited heat treater or plater still needs an underlying quality system to govern its document control, calibration, corrective action, and traceability, and your prime machining shop still needs AS9100 to govern the overall build. Think of NADCAP as the deep, narrow proof on a high-risk special process and AS9100 or ISO 9001 as the broad framework that runs the rest of the operation. For an aerospace part machined in San Bernardino, the realistic sourcing picture is a chain: an AS9100 machine shop performing the machining, then NADCAP-accredited processors performing each special process such as heat treat, plating, and nondestructive testing, all tied together by traceability and flow-down. Every link needs its appropriate credential. One uncovered special process breaks the part's traceability regardless of how strong the other links are, which is why buyers must verify both the system-level certifications and the process-level NADCAP accreditations across the entire chain.
