Bonding is an important point when it comes to ensuring the quality of each finished loudspeaker. What you need: Most precise adhesive dispensing and absolute repeatability in fast processes! preeflow dispensers are proven in loudspeaker dispensing applications worldwide: Bonding of coils, magnet system, membrane damper adhesives, wire fixation and contact protection. Smallest adhesive quantities starting from 0.001 ml can be applied – with a repeatability higher than 99%
