SYSTEMS AND METHODS FOR FORMING DIFFERENT PLASTIC PRODUCTS FROM SINGLE MELT Russian patent published in 2017 - IPC B29C47/50 

FIELD: technological processes.

SUBSTANCE: invention relates to an apparatus for forming different plastic products. Technical result is achieved by an apparatus for forming different plastic products from a single melt, which comprises a main extruder system and a second product extruder system. Main extruder system includes an extruder configured to melt a plastic resin to form a melt, an additive system configured to feed any additive to melt in extruder, a diverter system configured to transfer a portion of melt to a second product extruder system and a first die configured to form a first plastic product from undiverted melt. Second product extruder system comprises a product extruder configured to blend the melt with an additive, forming a second product melt, an additive feeder configured to feed product additive to second product extruder and a second die configured to form a second plastic product from second product melt. Efficiency of second product extruder system is not more than 75 % efficiency of main extruder.

EFFECT: enabling production of several products from one melt flow and reduced power consumption.
