FIELD: chemistry.
SUBSTANCE: invention relates to the field of foundry production. The method includes manufacturing a promodel, a mould and filling it with a metal-polymer compound. 150-170 parts of aluminium powder as a filling agent, 10-12 parts of polyethylenepolyamine as a hardening agent and 12-20 parts of dibutylphthalate as a plasticiser are taken per 100 parts of epoxy resin ED-20. Hardening of the metal-polymer composition is realised for 12-20 hours.
EFFECT: production of high-accuracy models is provided.
