Motan has designed the Metro G med material loaders (top photo) for plastics processors in the medical and pharmaceutical industries. The extensive family of loaders are said to meet all strict FDA hygiene requirements. Special filters with high-quality FDA compliant seals and electropolished stainless-steel surfaces are said to ensure reliable, dust- and contamination-free operation. A highlight is the new membrane implosion vacuum valve, which does not require compressed air.

Also, Motan’s Gravicolor 110 med gravimetric batch dosing and mixing unit (bottom photo) is tailored to the same target group. Motan developed this new FDA-compliant version for flexible and reliable mixing and dosing in injection molding, blow molding and extrusion applications.

The dosing and mixing technology is identical. Specially developed vertical slide valves dose and mix up to four different components precisely and with the highest recipe accuracy. The integrated and improved IntelliBlend analysis function records the recipe, material and operating environment, and documents all process data.

With the help of this function, the user achieves continuous self-optimization of the system and consequently the best possible operating point with the highest recipe accuracy and consistent, high product quality. Thanks to event-based logging, all parameter changes are stored in a control report and can be subsequently evaluated.
