Powder Feeder
In addition to standard powder feeders, we can also develop customized solutions that can be easily integrated into various types of coating systems.
For ultrafast laser metal deposition made to measure
Die ACunity Pulverförderer gewährleisten eine stabil hohe Leistung und eine einzigartige hochpräzise Mikro-Pulverzufuhrfunktion. Ihr modularer Aufbau bietet dem Anwender genügend Platz, um je nach Bedarf des Prozesses zwischen einer einzelnen Flasche bis zu maximal vier Flaschen zu wählen. Die Pulverflasche kann auch vollständig kundenspezifisch angepasst werden, unterteilt in 0,75 l, 1,5 l und 5 l, um den Anforderungen der EHLA-Technologie gerecht zu werden.
Sensor technology facilitates control and operability
The powder feeder is equipped with a special seal that can save 10-20 % of gas consumption compared to similar products on the market. The stirring function in the powder bottle can be set at intervals or continuously via the integrated touchscreen user interface. Each powder bottle is equipped with a powder level sensor that automatically indicates when the powder level is low so that the user can easily refill the powder. The special coating of the powder tray makes it more wear-resistant and durable, reducing the frequency of consumable replacements.

EHLA Optics & Powder Nozzles
Modularity is our strength. It is based on years of experience in hardware development. All core components of our systems can be combined and upgraded in a practical way.
Variety in design for different applications
The EHLA optics and powder nozzles have been developed for high-power lasers. The processing heads specially designed for external coating guarantee robust operation in EHLA and LMD processes with high performance.
The ACunity series nozzles for internal coating have been specially developed for laser metal deposition, repairing and hardening the internal surfaces of parts. They integrate laser, powder, gas and cooling water elements in a very small spatial structure.
