Abstract
FIELD: machine building. SUBSTANCE: method includes pouring of a polymer material in a mould, forming article with lugs, and hardening followed by article withdrawal accompanied by punch. Lugs are formed by the punch, the lateral surface of which has a recess of area being not less than 0.2 area of punch lateral surface, and of depth not exceeding article tolerance. EFFECT: production of thin walled transparent articles. 2 dwg
