Beschreibung
Zusammenfassung:	FIELD: polymer materials and metallurgy. SUBSTANCE: invention relates to manufacturing plastic parts using mold with its inside surface made completely or in part from steel. Polyurethane parts are manufactured in molds with inside surface made from tool steel containing, wt %: at least one element from group including tungsten 0-40, molybdenum 0-12, and vanadium 0-5; at least one element from group including chromium 1-6 and aluminum 0-15; if necessary carbon 0.1-1.5, cobalt 0.1-10, and nitrogen (in nitrated layer) 0-10. EFFECT: enabled detachment of part from mold without using internal lubricants. 3 cl, 6 ex
