FIELD: process engineering.
SUBSTANCE: extrusion head comprises split body made up of three sections with cooling system that form shaped-section forming channels, and communicated with head feed channel. Note here that top and bottom sections feature identical design and are provided with shaped grooves. Sine-shaped surfaces of the latter make sinusoidal forming channels in joint with third section whereon similar sinusoidal surfaces are located. Third section is provided with cooling system.
EFFECT: higher efficiency and quality of facing rails, and simplified design.
