VT machining provides precision chemical etching of molybdenum for customers who need burr-free, stress-free thin-metal parts made to an exact drawing. Molybdenum is high melting point, low thermal expansion and good thermal conductivity, and photochemical etching lets us reproduce fine features in it without the mechanical force, tooling cost or edge stress of stamping or laser cutting.
Why Chemically Etch Molybdenum?
Photochemical machining removes molybdenum by dissolving it through a patterned photoresist, so there is no contact force on the part. The result is completely flat, burr-free and free of the work-hardening and heat-affected zones that mechanical and thermal methods introduce. Because molybdenum is high melting point, low thermal expansion and good thermal conductivity, etching is often the only way to hold very fine apertures and intricate profiles in it economically.
Molybdenum Etching Capability
- Foil thickness typically 0.02–1.0 mm
- Minimum feature size around 0.8 × the metal thickness
- Burr-free, stress-free, perfectly flat parts
- Tooling-free — designs are revised in artwork, so prototypes are fast
- High repeatability from the same digital master across volume runs
Typical Applications
Molybdenum’s heat resistance makes etched moly valuable in electronics. Common etched molybdenum parts include heat spreaders, electrodes, semiconductor and high-temperature parts. Each is produced to your CAD or 2D drawing, with the open area, pitch and overall geometry made to order.
From Drawing to Delivered Molybdenum Parts
Send us your artwork, the molybdenum grade and thickness you need, and your quantity. We confirm feasibility, suggest the optimal foil and finish, prototype quickly and then scale to production from the same master. Post-etch finishing such as plating or passivation can be arranged where your application requires it.
