How to Overcome Technical Limitations in Automated Production of Loudspeakers and Headphones

If manufacturers of audio systems want to remain the first point of contact as partners of the automotive industry, quality must be guaranteed in addition to improved performance in assembly. One hurdle: Loudspeaker components are mostly bonded together. Only a technology that can guarantee precise dispensing of adhesives at high cycle rates is therefore suitable for reliable scaling from manual to semi- or fully automatic speaker production.

A forthcoming investment in new process equipment with dispensing technology brings with it a number of questions. This article explains why DC rotors from preeflow fulfill all the requirements for profitable and effective dispensing investments. Established in 2008, preeflow ensures precise, purely volumetric dispensing of liquids in the smallest of quantities.
