APPARATUS AND METHOD FOR MANUFACTURING MESH-LIKE POLYMERIC STRUCTURES

摘要

A method and apparatus for manufacturing a combined polymeric structure are disclosed. The apparatus includes an extruder body (110), a die (120) configured to receive flowing polymeric material from the extruder body (110) and a motion unit. The die includes a hollow inner die (122), a protecting sleeve (124) located within the inner die (122) and an outer die (125) located at an exit (128) end of the hollow inner die (122). The motion unit is configured to cause bidirectional translational motion of the hollow inner die (122) relative to the outer die (125).
