The technological parameters of the process and the design of the extrusion head for the manufacture of products such as pipe of polylactide composite materials by extrusion, its construction elements are calculated. Prototypes of a product made of biodegradable plastic were obtained.

The technological and operational properties of the obtained products depending on the content of talc filler and heat treatment parameters are investigated. The highest values of Vickat softening point are observed for heat-treated materials with a filler content of 2 %, and the optimal temperature and heat treatment are 120 °C and time 1015 min, respectively.
