CVM Technology
Next-Generation Powder Feeding System
CVM (Clogged Vibration Method) is an advanced powder feeding technology designed to provide a highly stable powder feed rate, long service life, and a wide feed-rate range. The system supports both gravity-fed powder delivery and gas-assisted direct powder feeding in DED processes. CVM technology is integrated into the built-in feeders of MX-Lab and is also available in stand-alone powder feeding systems such as PCM (Powder Control Module) Multi/Single.
*Based on PCM-Multi
- Feeds multi materials at the same time
- Gradually adjustable powder feed rate
- Not affected by metal powder ductility or shape
- Gravity / direct feeding available
- Impressively stable powder feed rate
