J&L provides certified fluorescent penetrant inspection (FPI) services to help manufacturers identify surface discontinuities without damaging critical components. Serving aerospace, medical, industrial, and defense industries, our nondestructive testing process helps verify product integrity, support quality control, and meet demanding inspection requirements.
Fluorescent penetrant inspection is a nondestructive testing (NDT) method used to detect cracks, porosity, and other surface discontinuities that may not be visible to the naked eye. By revealing defects before parts move into assembly or service, FPI helps manufacturers make informed quality decisions and reduce the risk of product failure.
J&L’s dedicated small-part fluorescent penetrant inspection line is designed specifically for medical and surgical implant manufacturers. Our process helps identify surface discontinuities in critical components while supporting the stringent quality standards required for medical applications.
Our multi-industry inspection line accommodates both small and large components for aerospace, industrial, and other demanding applications. Using qualified materials and industry-recognized inspection standards, J&L provides reliable, repeatable inspection backed by experienced Level III oversight.
J&L’s fluorescent penetrant inspection capabilities are supported by advanced equipment and technologies, including:
