METHOD OF REMOVAL OF FLASH AND FINS FROM POLYMER ARTICLES Russian patent published in 2004 - IPC

FIELD: treatment of rubber and plastic articles in containers at planetary rotation; mechanical engineering; removal of flash and fins. SUBSTANCE: proposed method includes loading articles together with solid filler into containers, cooling them to brittle state and imparting planetary rotation to containers in direction opposite to rotation of carrier. Containers are rotated relative to carrier at angular velocity determined from the following formula: , where ω_car is angular velocity of carrier rotation; D is inner diameter of container; K is coefficient = K = ω2car

(D-2L); L is distance between axes of carrier and containers; carrier of planetary mechanism rotates at angular velocity ωecar determined according to condition . EFFECT: intensification of process of removal of flash and fins; enhanced stability of process. 3 dwg
