Chigawo cha jakisoni chimakhala ndi zinthu zofunika kwambiri monga screw, mbiya, nozzle, hopper, metering, chipangizo chotumizira, jakisoni, ndi silinda yosuntha ya hydraulic, zomwe zimagwirira ntchito limodzi kuti amalize kuumba jekeseni wa pulasitiki. Chipangizo chomangira nkhungu ndichosiyana ndi{1}}makina awiri omaja jekeseni. Zimapangidwa ndi ma platens akutsogolo / kumbuyo, ma platen osuntha, zitseko (kapena ndodo zomangira), nkhungu zomangira ma hydraulic cylinders, nkhungu zoyendetsa ma hydraulic cylinders, makina otsekera nkhungu, chida chosinthira nkhungu, ndi chida chotulutsa zinthu. Zigawozi zimagwirira ntchito limodzi kuti zitsimikizire kulondola komanso kulondola kwa njira yopangira jekeseni.
Makina awiri-oumba jakisoni wa mbale amagwiritsa ntchito njira yachindunji yothamanga, pomwe masilinda anayi apamwamba kwambiri{1}}otseka nkhungu amagwirira ntchito limodzi kukokera zitseko, kuyika ndi kusunga kupanikizika pa nkhungu. Kupanga zigawo za pulasitiki kumaphatikizapo masitepe angapo: kutsekeka pang'onopang'ono, kutsekeka kwa nkhungu, kutsika pang'ono{3}}kutsekereza pang'onopang'ono, kutsekeka kwa mtedza, kutsekeka kwa mtedza, -kutsekera kotsekera kwa silinda, jekeseni, kutsekeka, kutulutsa kuthamanga pambuyo pogwira, -kuthamanga kwambiri, kutsegula, kutseka, {{}kutsegula nkhungu pang'onopang'ono,{6} kutsegula, kutsegula nkhungu pang'onopang'ono, kutulutsa kwazinthu, ndikuchotsa pini ya ejector. Masitepewa amapanga njira yopangira jekeseni wathunthu komanso wophatikizika.
