Innovative Dosing System BASIC saves time and money

(PresseBox) (Pinneberg, ) Pinneberg/Germany, July 28th, 2014 – Thanks to its innovative technical solutions, ROWASOL, the specialist for high-end colour and additive dispersions, customer specific liquid colours and additive concentrates, is always a step ahead of its competitors. The Pinneberg-sited company is currently proving a dosing system for extrusion applications that dispenses and homogenises the liquid colour into the plastic melt downstream. This means that the extruder is not contaminated with the colour, which represents a major advantage during colour changes with respect to savings of time and material. This type of dosing system is unique and allows the liquid colour to be fed safely into the pressure zone of the extrusion line.

The heart of the system is a high-precision gear pump from Oerlikon Barmag which can build up pressure of up to 80 bar. It is available in various models for dosing rates from 0.1 to 500 kg/h. A freely selectable feed tank, e.g. an IBC or the RAINBOW System, is connected to the pump via a plastic hose with non-drip quick release couplings. The extruder is connected via a stainless steel hose. The pressure-controlled purging and safety valves, developed exclusively for ROWASOL, are integrated into this line and guarantee fast and reliable colour changes.

To ensure that the liquid colour will be incorporated homogeneously before the system is installed, ROWASOL cooperates with PROMIX Solutions, the market leader in the field of static melt mixers. In collaboration with the customer, all relevant parameters are beforehand sent to PROMIX Solutions. The company then calculates whether the already installed mixer will provide homogeneous compounding and, if necessary, gives recommendations for more effective mixers or further modules.

The trial phase of the injection system is expected to be completed by the start of “Fakuma”, the international trade fair for plastics processing, at which the first results are to be presented in October.
