Gravimetric - Import export

SPECTROPLUS is a gravimetric & volumetric synchronous dosing & mixing unit for diverse materials – from granules, regrind or powders to liquids and flakes. Due to the modular design of the SPECTROPLUS with only one frame size and up to 8 dosing module positions, it is one of the most flexible overall systems in the motan product world. In addition to the gravimetric and volumetric version, the SPECTROPLUS can also be combined (gravimetric and volumetric dosing modules in combination). This makes it ideal for individual applications and also complex end products. motan's SPECTROFLEX units can easily be added to the SPECTROPLUS.

GRAVICOLOR doses and mixes up to six materials precisely and with maximum recipe accuracy. These modular gravimetric units are designed for injection, blow moulding and extrusion and provide throughputs up to 2200 kg/h. Independent of recipes, materials, or the operational environment, IntelliBlend analyses all process data achieving the best possible operating point at any time through continuous self-optimisation. Recipe integrity results in excellent and consistent product quality. The GRAVICOLOR series is part of the motan range of products and systems for all stages of management, conditioning and preparation of plastic granules. The design quality, plus the engineering, ensures high performance and reliable operation.

ULTRABLEND medical is a gravimetric batch dosing and mixing station for plastic granules, additives, and regrind. It has been specially designed for pharmaceutical and medical technology applications. The high dosing accuracy and consistency of the ULTRABLEND improves end product quality and saves money by using less additives and reducing scrap. The ULTRABLEND is suitable for direct mounting on small injection moulding machines and extruders. All components are accurately dosed and weighed one after another into a weigh hopper. They are then passed to the mixing chamber where they are homogeneously mixed.

The SOMOS® Gramix ExactDos dosing system is specifically designed for ultra-small volumes from a minimum throughput of 200 g/h (approx. 3.3 g/min) and can be combined with any continuous dosing unit.

The SOMOS® Gramix ExtremeDos dosing system is specially adapted for gravimetrically dosing regrind with very challenging flow behavior.

FUNCTIONAL PRINCIPLE The SOMOS® Gramix TwinDos dosing system supplies twin screw extruders in the "underfed" mode required for such extruders. Optimized hardware and control software ensure extremely short system response times, the weighing electronics operating with 24 bit signal resolution. For example, the system even responds automatically to changing regrind consistencies and optimizes itself by appropriately readjusting the metered components. No software adaptation (e.g. using appropriate material characteristic curves) is required for this purpose. The closed dosing system releases little dust and can be installed directly on the processing machine, so saving space.

The Batchmix 50 to 3000 models cover gravimetric dosing applications with throughputs of 5 to 3,000 kg/h. Usable for pellets and regrinds. Solutions for special applications are available. Depending on size, the machines can handle between 4 and 12 different materials and option packages are available to extend their functionality. The unique mixing technology used maximizes the dosing accuracy and uniformity of the mixed product.

SPECTROFLEX G is ideally suited for dosing powders, pellets, regrind, granulates, flakes and fibers in continuous processes. motan's unique interchangeable system provides two huge advantages over common dosing units. Firstly, the user can swap the quick exchange modules in less than one minute easily without any tools. Furthermore, the single and twin screw exchange modules are also interchangeable, allowing the user to configure the feeder for nearly any type of material in a matter of minutes.

"The demand for excellent mixing quality and consistently accurate dosing is a must when combining additives to the virgin material at the processing machine. The gravimetric MINICOLOR G dosing and mixing units meet and exceed these requirements. Mounted at the feed throat of the plastics processing machine, the units require very little space. Depending on need and requirement, screw or disc dosing modules can be installed at the mixing neck. Disc dosing is ideal for translucent and opaque parts as well as for dosing very small quantities."

With the METROFLOW gravimetric material loader, plastic processors can automate important areas of the production process cost-effectively and efficiently. The METROFLOW weighs every single load and evaluates the results, with a guaranteed precision of <1%. This improves the entire material management process and allows for full traceability. The material loaders come in 6, 10 and 30 liter volumes. The METROFLOW series is part of the motan range of products and systems for all stages of management, conditioning and preparation of plastic granules. The design quality, plus the engineering, ensures high performance and reliable operation.
