Bosch Packaging Technology showcases its latest version of the rotary pen assembly machine at Achema

At Achema, Bosch Packaging Technology will showcase its latest version of the rotary pen assembly machine MRA. Developed by the Bosch subsidiary Moeller & Devicon, the machine is designed to assemble medical devices such as standard four-piece disposable pens or single-shot auto-injectors.

Since then, we have refined the technology by cooperating with several manufacturers of pens and auto-injectors, and have adapted the assembly processes for different models,” Michael Andersen, sales director at Moeller & Devicon, explains. “This way we can offer customers the appropriate machine with the required features according to the pens or auto-injectors in use.” The new MRA can be combined with primary and secondary packaging solutions to complete lines.


Four pens at the same time
The MRA assembles the four components of each pen one step at a time: in-feed systems load the pen caps, cartridge holders, cartridges and dosing mechanisms into the machine from four different in-feed stations, and fit them together to ready-to-use pens. The fully-automated machine handles four pens at the same time and achieves an output of up to 70 pens per minute. Incorrectly assembled products are automatically detected and rejected.
