Amabhulogi

Umshini wokubumba onamakhanda amaningi ukhipha amajele amaningana emcimbini owodwa wokubumba; umshini wokubumba we-multi-cavity blow wenza izingxenye eziningana endaweni eyodwa yokuvala isikhunta. Ngokwesakhiwo esivamile samabhodlela amancane, izindawo zokufa kanye nezimbotshana zivame ukuklanywa njengohlelo olufanisiwe, kodwa amagama achaza izingxenye ezihlukene. Amakhanda engeziwe angakwazi ukuphakamisa izingxenye zomcimbi ngamunye kuphela lapho ukuhlukaniswa kwe-outlet, ububanzi bebhodlela, ubukhulu besikhunta, umthamo wokukhipha, ukupholisa kanye nezinto zokusebenza ezingezansi komfula konke kusekela umklamo.

Khetha umshini wokubumba wesiteshi esisodwa lapho isikhunta esisodwa singahlangabezana nesidingo esiqinisekisiwe nobulula, imvamisa yokushintsha, indawo yaphansi noma ukutshalwa kwesikhunta kubaluleke ngaphezu kokuphumayo okucatshangelwayo. Khetha umshini wokubumba weziteshi ezimbili lapho ukuphinda ukufunwa kungagcina iziteshi ezimbili ezishintshanayo zesikhunta zikhiqiza futhi i-extruder, i-die head, isistimu yokupholisa kanye nezinto zokusebenza ezansi nomfula zingasekela ukulandelana okusheshayo. Qhathanisa izingxenye ezinhle ngehora nebhodlela lakho langempela kanye nempahla—hhayi umjikelezo owomile wodwa.

Ungalungisi iphutha lokubumba igalelo ekubukekeni kwedwa. Ziqukethe izingxenye ezisolwayo, rekhoda umjikelezo wokuqala ongaphumeleli bese uqhathanisa inqubo nesisekelo esigunyaziwe. Nquma ukuthi iphutha lilandela uhlangothi olulodwa, umgodi owodwa, isikhunta esisodwa, inkatho eyodwa ye-resin noma umshini wonke. Hlola izinsiza, amazinga okushisa angempela, ukuziphatha kwesonto, ukuvala isikhunta, vunguza umoya nokupholisa ngaphambi kokushintsha iresiphi. Shintsha okuguquguqukayo okukodwa ngesikhathi, bumba imijikelezo eyanele ukuze ufinyelele esimweni esizinzile, futhi uqinisekise umphumela ngengxenye yesisindo, izilinganiso zodonga kanye nokuhlola okusebenzayo okudingekayo.

Idizayini enhle yokubumba isikhunta se-extrusion iqala ngengxenye eqediwe nokuhlolwa kokwamukela. Umklami wamathuluzi ube esesetha umugqa wokuhlukanisa, ukuncinza kanye namaphakethe ama-flash; ibeka ama-vents namasekhethi okupholisa; ichaza ukuxhumana kwentamo ne-blow-pin; ukhetha izinto ezifakiwe kanye nesikhunta; futhi ihlola ububanzi besikhunta, ubude, ukujiya, ukuvulwa kanye nezidingo zokubopha ngokumelene nomshini. Friza isikhunta kuphela ngemva kokuba umhlinzeki womshini, umenzi wesikhunta nomthengi begunyaze umdwebo ofanayo nezimo zesilingo.

Yakha uhlelo ngokuzungeza imanuwali yomshini kanye nezimo zokukhiqiza. Hlola amasistimu okuphepha, ukuvuza, izinga likawoyela nezinga lokushisa, izimo zomoya namanzi, ukuzinza kwe-extrusion, amathuluzi, okokugcoba, amakhabethe kagesi, izinzwa nomlando we-alamu. Qopha amathrendi futhi uhlele umsebenzi wokulungisa ngaphambi kokuba ushintsho oluncane lube yisikhathi sokuphumula esingahleliwe.

Cela ishidi lensiza eliqondene nephrojekthi kanye nomdwebo wohlelo olujwayelekile. Qinisekisa umthwalo kagesi oxhunyiwe, umthwalo olindelekile wokusebenza, i-voltage kanye nemvamisa, ukucindezela komoya ocindezelwe kanye nokugeleza, ukucindezela kwamanzi okupholisa, izinga lokushisa, ukugeleza nekhwalithi, i-drainage, isisindo somshini, ukulayisha phansi, ukuphakama kosilingi, ukuphakamisa ukufinyelela, i-exhaust, ukuphatha impahla, kanye nemishini ephansi yomfula.
