DIE FOR SHAPING PROFILED OBJECTS FROM POLYMER COMPOSITE MATERIALS Russian patent published in 1997 - IPC

Abstract RU 2088405 C1

FIELD: equipment for manufacturing composite material objects. SUBSTANCE: inclined walls of die are arranged under angle 5-60 deg. to die axis thereby forming preparatory zone of die. Working and preparatory zones are coupled with each other in the form of smooth curve. In addition, inclined walls of preparatory zone are coupled with each other along radius when convex-concave objects are fabricated. Length of working zone is 400-600 mm. Die is also provided with afterhardening section with individual temperature control system. afterhardening section is adjacent to working zone of die. On preparatory zone inlet, there is a face made with radius ≥ 0.5 mm. EFFECT: improved design of equipment. 5 cl, 4 dwg
