FIELD: process engineering.
SUBSTANCE: invention relates to casting. Proposed method comprises fabricating master patter, its potting, holding in die till hardening of compound and withdrawal of ready pattern. Pattern is made from polyurethane compound. Master pattern is made from silicone rubber. Ready patter is withdrawn from master patter in 10 to 90 min after potting.
EFFECT: reduced time of patter fabrication.
