Midwest Tungsten Service manufactures intricate parts of tungsten, molybdenum, or tantalum via EDM, water jet cutting, stamping, grinding, and CNC milling, drilling, and turning.
✔️ We can accept any format of CAD file from customers, or our engineers can generate one to your specifications.
✔️ Tolerances of ±0.0005 of an inch are possible
✔️ We specialize in high vacuum, medical, electronic, and aerospace applications.
✔️ Registered with the U.S. State Department's Directorate of Defense Trade Controls (DDTC) and compliant with ITAR (International Traffic in Arms Regulations)
✔️ US-based and US-owned
✔️ We machine to print on items designated as defense articles or controlled unclassified information (CUI), for non-export, U.S.-based work
✔️ Secure procedures in place to handle your prints for CUI or ITAR tungsten, tungsten heavy alloy, molybdenum, and tantalum parts
✔️ We maintain a current NIST SP 800-171 self-assessment and are pursuing CMMC Level 2 certification
We’re available to answer any questions regarding our products or services and provide quotes for custom projects. We look forward to hearing from you.
Despite the difficulty, our extensive machining experience allows us to machine materials other companies cannot. Some of the conventional machining methods we employ include saw cutting, turning, boring, tapping, threading, multi-axis milling, and grinding.
Midwest Tungsten houses a complete machine shop capable of machining parts to customer specification. We can accept both small and large run jobs of custom machined parts. We also have a full inspection department to assure your parts are correct. Certification of chemistry and physical properties are included at no charge. Dimensional inspection reports can also be obtained by request.
Waterjet cutting is best for smaller volume parts or for parts of thicker stock. This process is relatively quick, but is not suitable for parts with tight dimensional tolerances. For parts with high tolerances, we suggest EDM cutting.
Because tungsten is a very hard material, conventional machining is often difficult or impossible. We utilize Electrical Discharge Machining (EDM) to overcome this difficulty. EDM machining allows for intricate cutting with tight tolerances and allows us to create holes smaller and deeper than would otherwise be possible in tungsten.
As tungsten is difficult to conventionally machine, we often use grinding to manufacture parts with tight tolerances or fine surface finish requirements.
Our current capabilities include the winding of evaporation filaments, electron beam, and ion beam filaments with both single and multistrand wire. Much of our computer-controlled equipment was built in-house to guarantee precision and repeatability. In addition to winding, we form wire into a variety of shapes using CNC benders, four-slides, and custom jigs and fixtures.
Midwest Tungsten Service has numerous stamping and forming presses, brakes and shears. We also have CNC punches and tack welding equipment to form refractory metal sheet into the products that you need.
