Extrusion International 3-2020

45 Extrusion International 3/2020 Aleko Machinery http://en.polimerexpert.ru/ Both types of dosing systems have proven themselves, but the designers keep up- grading them to meet market needs. For ex- ample, the new design of the weighing hopper makes it easy to modify the dosing system from four to six-component – unlike the analogues offered by competing companies. Material supply and extrusion control Continuing the devel- opment of the product line of dosing systems, Aleko company has ex- panded the range with extrusion control feeding system, Optionally, the system can be equipped with a raw material mixer for pre-mixing portions before feed- ing it into the screw. The described system at a low cost allows to achieve a high degree of automation and production stability where dosing of a large number of components is not required. By optimizing the work of designers, production technology and its local- ization in Russia, as well as through a careful selection of components, Aleko specialists can offer custom- ers affordable prices, but at the same time high-quality solutions for mate- rial dosing systems, which have re- ceived very positive feedback in the market.

The extrusion control system is equipped with a loading hopper, which supplies the ma- terial to the weighing tank, where tension sensors record the val- ue of the weight of the supplied batch. Then the raw material is fed into the feeding zone area of the screw.
