Our castings are used in a wide variety of applications including those requiring X-Rays, Pressure Testing, Penetrant Testing, CE marking, NDT testing, sampling schedules, chemical and physical certifications, plating, polishing, or machining. We have two spectrometers to check every batch of metal before we pour. We do PPAPs. We use our FaroArm for FAI and have laser scanning for model matching.
