FIELD: process engineering.
SUBSTANCE: invention relates to production of articles from polymer materials and may be used in chemical industry for making polymer profile bars. Proposed two-channel extrusion head comprises split body consisting of four sections. Recess for coolant circulation is arranged at the center between two sections. Note here that said sections compose two forming channels communicated with feed channel. Forming channels feature profile section with three grooves made symmetrically at channel bottom, two ellipsoidal ledges and one triangular ledge at channel top part that make top surface at edges with inclined straight lines corresponding to side of triangular ledge.
EFFECT: simplified design, higher quality of finished articles.
