FIELD: technology for producing electric equipment used in aircrafts, in particular ignition device of aviation gas-turbine engines and liquid rocket engines, possible use for manufacturing products with usage of foamed plastics facing increased heat resistance and heat requirements.
SUBSTANCE: during production of electric equipment encased in packed or sealed cover, internal hollow of electric equipment cover is filled with fine-dispersed foamed plastic powder, cover is aged under increased temperature during the time, sufficient for foaming and solidification of foamed plastic, cover with electric equipment elements and solidified foamed plastic located within is cooled down, packed or sealed with installation of structural lid. In accordance to invention, cover with foamed plastic is aged at increased temperature and then cooled down, both under excessive pressure of gaseous substance surrounding the cover being heated.
EFFECT: increased heat resistance and strength of electric equipment encased in packed or sealed cover.
