These equipments are necessary for the production of PETs. The machine is composed of the plasticizing furnace and the high pressure blowing unit. In this case, the machine is serviced by an operator that introduces the preforms into the plasticizing furnace, after which they must be introduced into the blowing unit. The maximum capacity of a semi-automatic Blow moulder can reach up to 800-900 pcs / h, depending on the operator and the volume of PETs.
