Inspection & Special Processes


Whitcraft’s in-house inspection, testing, and special processes help maintain cost efficiencies and delivery timelines. Our highly-skilled experts and our carefully designed special processes help ensure the parts you receive will perform to design intent.


A coordinate measuring machine (CMM) tests final products against design intent by measuring precise physical geometrical characteristics of an object using a probe and laser scanning technology.



Blue etch anodizing (BEA) is a specialized, highly sensitive non-destructive testing (NDT) technique for detecting surface discontinuities such as laps, cracks, material segregation, heat-treating imperfections, and abnormalities caused by machining.



Fluorescent Penetrant Inspection (FPI) is a type of dye penetrant inspection in which a fluorescent dye is applied to the surface of a non-porous material in order to detect defects that may compromise the integrity or quality of the part in question.



Heat Treating is used to provide final and/or intermediate material properties and stress conditions necessary for end use or intermediate processing. Heat treating is an additional way to help enhance material properties in our forgings to produce reliable end-use hardware. This process is carried out in tightly controlled furnaces.



Chemical Processing is used to clean, prepare, and inspect forgings during the forging manufacturing process. Chemical processing allows for mass production of operations that would otherwise be tedious and labor intensive when other methods are used. Chemical processing is carried out by various methods, including manual and automated operations through multiple compositions of chemical baths.
