FIELD: process engineering.
SUBSTANCE: method for power circulation related to plastic container blow moulding machine including air power circulation system for reuse of said power of air released from blow moulding machine cavities. Said blow moulding machine can reuse released air at given pressure for further blowing in working cavity. Note here that said machine comprises first and second means of blowing of primary or secondary air in appropriate air reservoir. Said machine comprises also circulation means for reuse of blowing air released from cavities at first stage of releasing air from containers.
EFFECT: optimised use of air power, higher efficiency of blow moulding.
