I, II, and III, MIL-DTL-83723 series III and MIL-DTL-26500. It also manufactures commercial equivalents to MIL-DTL-5051, MIL-DTL-26482, EN2997 and ESC10. e connectors go through 27 different processes during production. To create the insulator, a glass pellet is inserted into the shell using a graphite fixture designed to withstand high temperatures. It then very slowly travels across a conveyor through multiple heating zones of an oven that heats to higher than 2,000°F. e metal of the shell expands, and the glass becomes a gel state. As the components move through the oven and gradually move to cooler tempera- tures, the glass hardens first and the metal compresses to create the seal. e compression seal is so restrictive that helium testing has indicated it would take 5,000 years for one cubic inch of air to pass through. Connectors are available in various shapes and with different fit-throughs and headers. Materials may be stain- less, Inconel or other alloys, depending on the application. Measuring Up e company's experience with the precision require- ments of the connectors has furthered its understanding of test and measure processes. Qualifying a part such as the connector can amount to as much as $500,000, so AMPI has found that it is best to keep all of its quality control processes in-house. With its existing substantial investment in test and measurement equipment, the company is even considering expanding to become a lab that will offer these capabilities as a service. Federico Veneziano, company COO/CFO, says instead of using the term "quality management system" (QMS), AMPI tabs its approach as a business management system (BMS). "We want to make sure the entire organization has the same set of goals for product quality, rather than restricting the approach to within the quality department alone," he says. "Everyone contributes to the quality of the final product." In its efforts to keep up with the ever-tightening require- ments of multiple industries driving to zero-defect, the company has attained a stream of certifications and accreditations, including ISO9001, IATF16949, AS9100, NADCAP and ITAR. e quality department includes a nice lineup of inspection and measurement equipment specific to various part features. e CMM allows measure- ment of the geometry of physical objects by sensing discrete points on the surface of the object with a probe. e Zeiss Rondcom allows measurement of cylindricity, roundness and TIR. Tesa-Scan systems verify with vision capability a different array of outside dimensions of a part. e quality department also includes an OGP SmartScope, a Zeiss Surfcom surface texture and contour measuring system, a Formtracer surface roughness analyzer and several optical comparators, along with more than 2,500 precision measuring tools. :: The vision system can check multiple dimensions from two different angles, feeding as many as 7,200 parts per hour. :: The company's particle-counting microscope can magnify to 600×, allowing close examination in critical applications.
