Sonke siyazi ukuthi imikhiqizo yepulasitiki ivame ukuba nesilinganiso sokuncipha, futhi incipha uma iba phansi. Imikhiqizo eyenziwe ngezinto ezahlukene inesilinganiso sokuncipha esihlukile. Lapha, sixoxa ngezinto eziningana ezithonya ukuncipha kwamabhokisi okushintshana kwepulasitiki ngesikhathi sesigaba sokukhiqiza. Eqinisweni, ekukhiqizeni, uma ufuna usayizi womkhiqizo ufaneleke kakhudlwana, kuyasiza ukuqonda izici ezithinta ukuncipha. Phela, embonini yezokuthutha yezimboni, izitsha zokushintshana kwepulasitiki ngokuvamile ziyizitsha ezijwayelekile ezijwayelekile. Usayizi wazo kanye nokucaciswa kwazo kunembile ngokwezinga, futhi akukho ukuphambuka. Ngaphandle kwalokho, akunakushiwo ukuthi ukujwayelekile kujwayelekile.
Inqubo yokubumba yeibhokisi lokushintshana kwepulasitikiyi-thermoplastic molding. Ngenxa yokushintsha kwevolumu ngesikhathi senqubo yokukhiqiza enkambisweni yokwenza ikristalu, ukucindezeleka kwangaphakathi kukhulu kakhulu, futhi kukhona ukucindezeleka okusele ngaphakathi komkhiqizo wesikhunta, futhi ukuqondiswa kwama-molecule kunamandla kakhulu. Ngakho-ke, inesilinganiso sokuncipha esiphezulu kunemikhiqizo yepulasitiki ye-thermosetting. Inebanga lokufinyela elikhulu kanye nesiqondiso esicacile kakhulu. Njengoba ungqimba lwangaphandle lwezinto ezincibilikisiwe luthintana nomphezulu wesikhunta ngesikhathi sengxenye yepulasitiki ebunjiwe, luyapholiswa ngokushesha ukuze kwakheke igobolondo eliqinile eliphansi. Futhi sonke siyazi ukuthi ukuhanjiswa kokushisa kwepulasitiki kubi kakhulu, futhi ungqimba lwangaphakathi lwebhokisi lokushintshana kwepulasitiki luphola kancane kakhulu, lwakha ungqimba oluqinile oluqinile olunesilinganiso esikhulu sokuncipha. Uma ubukhulu bodonga buhamba kancane, ungqimba oluphezulu luzoqina futhi luzoncipha kakhulu.

Uhlobo lwe-feed port lokukhiqiza imishini'size ukusatshalaliswa kwezinto zokusetshenziswa kanye nezinye izici kuzothinta ngqo isiqondiso sokugeleza, ukusatshalaliswa kobuningi bezinto zomkhiqizo, ukuncipha kokuvikelwa kwengcindezi kanye nesikhathi sokubumba, kuthinte ngokungaqondile izinga lokuncipha kweibhokisi lokushintshana kwepulasitiki.Uma imishini inokungena okuqondile, ingxenye yokuwela kokungena inkulu kakhulu, ikakhulukazi uma ijiyile, izinga lokuncipha lizoba lincane kodwa liqonde ngqo. Ngokuphambene nalokho, uma usayizi wokungena uncane, isiqondiso sokufinyela sincane, kanti izinga lokuncipha lilikhulu uma ukungena kuseduze kakhulu nokungena noma kufana nesiqondiso sokugeleza.
Izimo zokubumba zokukhiqiza zinethonya elikhulu esilinganisweni sokuncipha kweibhokisi lokushintshana kwepulasitikiIsibonelo, uma izinga lokushisa lesikhunta liphezulu futhi izinto ezincibilikisiwe zihamba kancane, kuba nobuningi obukhulu futhi izinga lokuncipha lizoba likhulu kakhulu. Izinto ezikristalu zinekristalu ephezulu kanye nomthamo omkhulu, ngakho izinga lokuncipha liba likhulu. Ukusatshalaliswa kwezinga lokushisa lesikhunta kanye nezinga lokupholisa langaphakathi nangaphandle kanye nokufana kobuningi bezingxenye zepulasitiki kuzothinta ngqo izinga lokuncipha kanye nokuqondisa kwengxenye ngayinye yomkhiqizo. Usayizi wengcindezi yokugcina kanye nobude besikhathi sokugcina nakho kunomthelela omkhulu esilinganisweni sokuncipha. Uma ingcindezi iphezulu futhi inde, izinga lokuncipha lincane, kodwa isiqondiso sikhulu. Ngesikhathi senqubo yokubumba, izinga lokuncipha kwebhokisi lokushintshana lepulasitiki lingashintshwa ngokufanele ngokulungisa izinga lokushisa lesikhunta kanye nesivinini sokufakwa kwengcindezi kanye nesikhathi sokupholisa. Ngokusho okungenhla, singanquma izinga lokuncipha kwengxenye ngayinye yomkhiqizo ngokuya ngesimo sokungena kwebhokisi lokushintshana lepulasitiki kanye nosayizi kanye nokusatshalaliswa komklamo wesikhunta, bese sibala usayizi wesikhala. Ngokwezinga langempela lokuncipha komkhiqizo, shintsha isikhunta bese ushintsha izimo zokubumba ngomjovo ukuze ulungise izinga lokuncipha komkhiqizo ukuze uhlangabezane nezidingo zangempela.
