Sensors Industry Expertise

Rehtek Machine is an AS9100D Registered. We are a trusted vendor/partner in the sensor manufacturing industry. This niche expertise and experience with attention to microscopic details meeting the tightest tolerances has grown our business for over 30 years. We know hermetic seals, deep hole drilling starting at .008Dia and critical to quality features for sensor components. We track and excel at machining DFAR’s compliant exotic alloys Our team of manufacturing engineers, machinists, and operators excel at meeting your dimensional tolerancing, cosmetic appearance, and the “microscope serves as our eyes” for microscopic burr and all FOD removal.

Process Friendly Header Shell

We understand the glass to metal sealing industry and that header shells have critical to process features. We pay close attention to hermetic seal surfaces, laser beam welding process, burr and nick free surfaces insure a quality seal.  We have experience and expertise in machining kovar, stainless, titanium and inconel.

Header Shell with Braze Hole

Header shell with braze hole +.0005-0000 close fit tolerance ensuring capillary actions for brazing of tubes and glass wire seals. We maintain tight tolerences on depths and diameters so your parts flow thru the sealing process 

Creativity In Header Shells

We understand the glass to metal sealing industry and that header shells have unique features. We pay close attention to critical to quality function surfaces to insure a quality seal.  We have experience and expertise in machining kovar, stainless, titanium and inconel.

Feed Thru Shell

We understand the glass to metal sealing industry and that feed thru shells have critical wall thicknesses.  We are able to machine .003 wall thickness on turn part .125 diameter in kovar and stainless steel.

Inconel Port with UNJ Threads

We have the teachnical skills to machine and hold size on inconel ports with critical sealing surfaces.


Our Enterprise Resource Planning System, or ERP, is done through Shoptech MFG. This software platform allows us to digitalize our entire process, from estimate to quote, machining to final inspection, all the way to billing. Every step is completely controlled and contained within this ERP, making your product 100% trackable and traceable.

Sensor raw material alloys are designed specifically for the sensor field because they can hold up in very harsh, intense environments, for example, the high heat of a jet engine or a caustic, corrosive chemical application or extreme pressure of hydraulic systems. These raw materials are specific to the glass to metal sealing industry as well. These alloys need to be dynamic, functional, durable, and strong enough to function in  the harshest environments

Machining expertise with the following sensor raw materials:

  • Inconel
  • Titanium
  • Kovar
  • Stainless steel
  • Invar
  • Hastelloy
  • Monel
  • Nickel
  • Alloy 42/52
  • Copper
  • Molybdenum
  • Nitralloy


Sensors require machined components that have critical to quality and functionality  features . These features are specific to the functionality of a high performance sensor. Our sensor machining experience and expertise are our machining niche yielding a  precisely controlled machining process. We understand the critical features and machine and deburr components with detailed attention to insure process friendly features used in the glass to metal hermetic sealing process.
