Industries Served by MHV
We work with major corporations worldwide on crucial industrial vacuum system needs.
At Metallurgical High Vacuum (MHV), we partner with major corporations worldwide to meet their crucial industrial needs. We leverage our high vacuum technology expertise across a broad spectrum of industries, providing tailored solutions for a variety of applications.
High vacuum technology enables manufacturing processes to occur under vacuum levels down to the low 10-6 torr range and at elevated temperatures exceeding 1300 oC (2375 oF), creating products that are integral to daily life. Here’s how we serve key industries:
Aerospace
High vacuum technology is essential in the aerospace industry, particularly in the production of jet engine turbine blades and vanes using a “lost wax process”. These components are vacuum cast in preheated ceramic molds and later vacuum coated via physical vapor deposition processes. Controlled solidification in the mold chamber can produce equiaxed, directionally solidified, or single crystal castings.
Helium Leak Testing is required on all vacuum chambers to prevent deleterious gasses, e.g. atmospheric oxygen, nitrogen, and water vapor from entering the process causing a host of metallurgical issues. Later processing of these components may require high temperature treatment also in high vacuum.
Metallurgical High Vacuum’s Pump Sentinel has been installed on several rotary piston pumps for this industry as well as our Full Pressure Lubrication/Failsafe Lubrication optimization.
Automotive
Front and rear automotive lighting components are metalized and top coated using resistance or sputtered PVC processing in high vacuum. The reflective layer is usually pure aluminum with a plasma activated organo-metalic (HMDS) top coat applied in the vacuum chamber after. The top coat is a quartz derivative which protects the aluminum film.
Transmission torque converters are electron beam (EB) welded occurring in high vacuum (low 10-5 torr).
Metallurgical High Vacuum’s Full Pressure Lubrication/Failsafe Lubrication optimization, as many of our clients have and benefited from.
Healthcare
Titanium alloy orthopedic implants are cast under high vacuum, again using ceramic preheated molds and lost wax processes. Helium Leak Testing is a critical need here and Metallurgical High Vacuum excels at providing appropriate leak testing services at any clients facilities.
Heat Treating
Tools and metal parts are frequently heated under high vacuum and then quickly cooled to achieve the right combination of strength, hardness, and flexibility.
Food Processing
High vacuum technology is used to manufacture foil packaging by evaporating or sputtering metal and layering it onto a plastic film. Food is also freeze-dried under vacuum to reduce spoilage and extend freshness. With our On-Site Services, we can ensure these processes are optimized for maximum efficiency.
Metallurgical
Vacuum induction furnaces are used to provide high purity melt stock for aerospace castings. These use induction coils surrounding a refractory crucible. Alloys melted include nickel and cobalt base.
Reactive metals such as titanium alloys are melted using electron beams. The electron gun is pumped to a low 10-5 torr vacuum while the melt chamber is held at a low 10-2 torr vacuum. Electron beam (EB) guns have power ranges that exceed 150 kW (5 amps beam current and 30 kV accelerating potential).
Explore Metallurgical High Vacuum’s HD 300 and HS 430 manufactured rotary piston pumps with spin-on particulate and acid filtration, the only solution for added value when it comes to aggressive industrial processes.
