Extrusion International USA 2-2020

53 Extrusion International 2/2020 the total number of actuators in the device is 144 pcs.: 72 pcs. for the volume of the air flow and 72 pcs. for temperature control. The de- signed system exceeds all similar devices available on the market in terms of the number of adjustment points (for its diameter). In the case of a die head with diameter of 450 to 600 mm, the number of adjust- ment zones will already reach the number of 184 pieces – 92 on each level, respectively. Service and customer support The design of the device is designed in such a way that servicing does not cause difficulties.

ALEKO’s own customer service is ready to provide technical support at any time, both in a remote mode and with the departure of specialists to the client’s territory. Cost-efficient and convenient At the moment, the ALEKO system for monitoring and control of thick- ness variations of polyethylene films is the most affordable device among similar offers in the market. It is im- portant that it can be installed both on new blown film machines and on existing extrusion lines in order to improve film parameters and save raw materials. Fast return on invest- ment and reduced costs are guaran- teed. A device for monitoring and control of thickness variations has already been presented both at well-known Russian exhibitions and at the larg- est European exhibition – K 2019. The received feedback and high in- terest in the product confirms the need for the majority of polymer market players in such equipment and an understanding of the real economic effect of its use.
