FIELD: process engineering.
SUBSTANCE: proposed method comprises processing material consisting of, at least, first and second parts. Note here that said material is a semi-finished product to be subjected to thermal treatment by electromagnetic power so that said first and second parts are heated in dissimilar ways. At the stage of unequal heating, viscosity of said first part is decreased to render said part a fluid, while second viscosity is, mainly, unchanged or insignificantly reduced. After heating, first and second parts are shaped or moulded to get finished product. Proposed system comprises semi-finished product holder including heating device and shaping or moulding sections. Invention covers also the composition of material made up of two parts.
EFFECT: simplified and efficient process.
