Isixhumanisi esiyinhloko ekucubungulweni kwepulasitiki. Kudingeka izinhlobo ezahlukene zemikhiqizo yepulasitiki noma izimo zezingxenye. Kunezindlela zokubumba ezingafika ku-30, ezincike kakhulu ohlotsheni lwepulasitiki, ukukhetha kusuka efomini kanye nesimo nosayizi womkhiqizo. Izindlela zokucubungula ipulasitiki ezisetshenziswa kakhulu yi-thermoplastic extrusion, i-injection molding, i-calendaring, i-blow molding kanye ne-thermoforming. I-thermosetting plastic molding evame ukusetshenziswa ekucubungulweni kwepulasitiki isebenzisa futhi i-transfer molding, i-injection molding, i-laminate molding kanye ne-thermoforming. Ngaphezu kwalokho, kunezindlela ezifana ne-casting ngama-monomers noma ama-polymer njengezinto zokusetshenziswa. Phakathi kwalezi zindlela, i-extrusion kanye ne-injection molding kusetshenziswa kakhulu, futhi futhi yizona zindlela eziyisisekelo kakhulu.
Insimbi nokhuni kusetshenziselwa ukucubungula amapulasitiki. Njengoba izakhiwo zepulasitiki zihlukile kwezensimbi nokhuni, ukuhanjiswa kokushisa okubi, i-coefficient ephansi yokwanda kokushisa, i-modulus ephansi yokuguquguquka, ingcindezi enkulu kakhulu ezintweni noma amathuluzi, kulula ukubangela ukuguquka, kanye nokushisa okusikayo kulula ukuncibilikisa. , Futhi kulula ukunamathela kuthuluzi. Ngakho-ke, imishini yepulasitiki, amathuluzi okusika kanye nesivinini sokusika esihambisanayo kumele kuvumelane nezici zepulasitiki, kanti ezinye izindlela ezivamile zokucubungula ukusaha, ukusika, ukubhoboza, ukujika, ukuplana, ukubhoboza, ukugaya, ukupholisha, ukucubungula intambo, njll. Ngaphezu kwalokho, amapulasitiki angasikwa nge-laser, agxishwe ngesitembu, futhi ashiselwe.
Kunezindlela zokushisela kanye nezokunamathelisa zokucubungula ipulasitiki. Ukushisela ukusebenzisa umoya oshisayo ukushisela ama-electrode, ukushisela okuncibilikisayo okushisa kusetshenziswa ukushisa, kanye nezindlela zokushisela ezifana nokushisela okuvamise kakhulu, ukushisela kokungqubuzana, ukushisela kokungeniswa, ukushisela kwe-ultrasonic kanye nokushisela kwe-laser. Ama-adhesive ahlukaniswe ngama-solvents, izixazululo ze-resin kanye nama-adhesive ancibilikisayo ashisayo.
Izindlela zokubopha, ukushisela kanye nokuxhumanisa ngomshini zenza kube lula ukuhlanganisa izingxenye zepulasitiki zibe umsebenzi ophelele womkhiqizo.

Singenza imikhiqizo yepulasitiki yanoma yiluphi usayizi, singochwephesheisikhuntaumenzi
