Nikeza umdwebo wengxenye, ibanga le-resin, isisindo okuhlosiwe, izindawo ezibucayi zodonga, intamo kanye nobukhulu obuphelele, ipulani yokunquma, ukuhlolwa kokuvuza noma ukucindezela, indlela yokubona, okuhloswe ngakho kanye nezinsiza zezitshalo. Umbiko wesilingo owusizo uxhumanisa amasampula amukelekile ekubunjweni okuqondile, okubalulekile kanye nokubuyekezwa kweresiphi.
Iziqukathi ezincane kanye nemiklamo ephumayo ephezulu ingalingana aumshini wokubumba oqhubekayo we-extrusion blowing. Izingxenye ezinkulu noma ezinzima zingadinga ii-accumulator blow umshini wokubumba. Ukukhetha okulungile kuncike engxenyeni nephakheji yenqubo, hhayi igama elinesici kuphela. Dlulisa amehlo ku-Kinggle'sizinhlelo zokusebenza zokubumbanoma uthumele ulwazi lomkhiqizo lwangempela ngengxoxo eqondene nephrojekthi.
Imibuzo ejwayelekile ukubuzwa
Yiziphi izici ezivame kakhulu zokubumba i-extrusion blow?
Amaphutha avamile ahlanganisa i-flash eyeqile, ukuncinza okubuthakathaka noma okusikiwe, ukujiya kodonga olungalingani, amakhona amancanyana, i-parison sag noma i-curl, ukuphuka kwe-ncibilika, amabhamuza, amachashaza amnyama, imigqa yokufa, ukuvunguza okungaphelele, ukuphuma, i-warpage nokuvuza.
Yini ebangela ukushuba kodonga olungalingani ekubumbeni igalelo?
Izimbangela ezingenzeka zihlanganisa indawo yephrofayili, i-die centering, i-parison sag, i-extrusion engazinzile noma usayizi wokudutshulwa, ukuqondanisa kwesikhunta, ukupholisa okungalingani kanye nenani lokwelula elidingwa ingxenye yejometri.
Uyinciphisa kanjani i-flash ekubumbeni i-extrusion blow?
Okokuqala hlola lapho ukukhanya kuvela khona, ingxenye yesisindo, ukubekwa kwejele, ukuvala ukuvala isikhunta, ukuziphatha kokubopha, ukuqondanisa kanye nesimo sokuncinza. Lungisa iphutha lokuvala noma lamathuluzi ngaphambi kokushintsha isisindo sengxenye yomhlaba.
Kungani kukhona amabhamuza engxenyeni ebunjiwe?
Izimbangela ezingase zibe khona zihlanganisa ukufingqa noma umswakama, igesi evaleleke, ukuncibilika okunganele, ukuvuza kwempahla, okonakele kanye nokungcoliswa. Hlola isidingo se-resin kanye nendlela yezinto ezibonakalayo ngaphambi kokushintsha inqubo.
Ingabe uhlelo lwesonto lungalungisa wonke amaphutha odonga oluncane?
Cha. Ukuhlelwa kwe-Parison akukwazi ukwethenjwa ngokuthembekile ukulungisa iphutha lokufa, i-extrusion engazinzile, amathuluzi awonakele, ukupholisa okungekuhle, ukuma kwesikhunta okungalungile noma i-actuator engasebenzi.
Yini okufanele ishintshwe kuqala ngesikhathi sokulungisa inkinga?
Okokuqala buyisela futhi uqinisekise impahla egunyaziwe, iresiphi, insiza kanye nesisekelo sesimo somshini. Ngemva kokukhomba isendlalelo esingase sibe khona, shintsha okuguquguqukayo okukodwa okulawulwayo bese uphinda izilinganiso zengxenye efanayo.
Kungani iphutha elifanayo libuyela kwenye i-shift?
Iziphambeko eziphindelelayo zivame ukubuya lapho ukubuyekezwa kwamaresiphi, izinguquko zempahla, ukufundwa kwezinsiza, ama-alamu nezenzo zokulungisa zingarekhodwa njalo. Ilogi eyabelwe enesici kanye nesisekelo esivikelekile senza inqubo iphindeke.
