In the form of the tesla blue, the new family of application heads from Baumer hhs includes a 24 V head that can be used to replace existing hot melt application heads by the Plug & Play principle. It takes next to no time to replace the previously used electropneumatic application heads with the new hot melt application head, which is compatible with most of the plug-and-socket connectors available on the market. Since the tesla blue – and equally the tesla red – can moreover be operated by any PLC, no further modifications are necessary on the existing production equipment once the application heads have been replaced. This means that end-of-line packers and packaging producers can switch their hot melt application to the latest technology with a minimum of installation effort and investment. That offers them decisive advantages. For example, being an electromagnetic hot melt application head, the tesla blue – like all the heads of the tesla family – is characterised by a much longer service life compared to electropneumatic hot melt application heads, something that significantly improves the reliability of glue application in day-to-day production. End-of-line packers and packaging producers can ultimately better exploit the productivity of their production lines. In addition to which, the tesla heads guarantee the familiar, high application quality of Baumer hhs gluing systems when applying both hot melt beads and hot melt dots. tesla is the name of the high-speed application head from the tesla family. It is operated via a controller from Baumer hhs and can process high viscosities at an adhesive pressure of up to 80 bar. The wider viscosity and pressure range makes it possible to use electromagnetic hot melt application heads even in segments that were previously reserved for electropneumatic heads. The maximum frequency of up to 600 Hz offers plenty of room for increasing productivity and for saving adhesive by applying dots instead of lines.
