Isikhunta sesithuthuthu siyithuluzi elinembile elisetshenziselwa ukukhiqiza izingxenye eziphindaphindwayo nezinembe ngosayizi ngokusebenzisa ipulasitiki yokubumba. Lezi zikhunta zichaza isakhiwo, ukubukeka, kanye nokusebenza kwezingxenye ezibalulekile, okwenza ikhwalithi yesikhunta ngokwayo ibe yinto eyodwa ebaluleke kakhulu enquma impumelelo yomkhiqizo wokugcina.
Kubakhiqizi kanye nama-OEM afuna isikhunta somzimba wesithuthuthu esenziwe ngokwezifiso, ukuqonda amakhono okuklama nokukhiqiza omhlinzeki wesikhunta kubalulekile. Lesi sihloko sihlola inqubo ephelele yokukhiqiza isikhunta sezithuthuthu esenziwe ngokwezifiso futhi siqokomisa ukuthi yini ehlukanisa abakhiqizi abaphambili embonini.
Izikhunta zokujova ngepulasitiki yesithuthuthu zisetshenziswa kuzo zonke izingxenye ezahlukahlukene:
● Ama-Fairings nama-Body Panels – Kudinga ama-contour aqondile ukudala izindawo ezibushelelezi, eziguquguqukayo ezinokulingana okuphelele kokuhlanganiswa
● Ama-Fender Angaphambili Nangemuva - Ukumelana nobunzima obudingayo kanye nokuqina kobukhulu
● Izimbozo Zethangi Likaphethiloli - Ukugxila ekumelaneni nokushayisana, ukuqina, kanye nokukhanga kobuhle
● Izimbozo Zesibani Sangaphambili Nesesibani Sangemuva – Kudinga ukucaca okubonakalayo ngokusebenzisa imigodi yesikhunta ecwebezelisiwe
● Amaphaneli Ezinsimbi Nezimbozo Zokulawula - Kudingeka imiklamo ye-ergonomic kanye nokuvalwa okuvikela isimo sezulu
Ukukhetha ipulasitiki kuthinta amandla omshini, ukumelana nokushisa, ukuqina kwe-UV, kanye nokumelana namakhemikhali. Izinto ezivamile zifaka:
● I-ABS (i-Acrylonitrile Butadiene Styrene) – Ukumelana okukhulu nokuphela okuphezulu kwendawo; isetshenziswa kabanzi kuma-fairings namaphaneli omzimba
● I-Polycarbonate (PC) – Ukuqina okuhle kakhulu kanye nokucaca okubonakalayo kwezingxenye zokukhanyisa
● Inayiloni (PA) ene-Glass Fiber – Amandla aphezulu okusebenza kanye nokumelana nokuguguleka kwezingxenye zesakhiwo
● I-Polypropylene (PP) – Ilula futhi inamandla aphezulu okumelana nokushaya
● Izinhlanganisela ezigcwele ingilazi – Amandla athuthukisiwe kanye nokumelana nokushisa kwezicelo ezidinga amandla amaningi.
Inqubo Yokukhiqiza Isikhunta Esingokwezifiso: Ubuchwepheshe Obusezingeni Eliphezulu
Ukudala isikhunta sesithuthuthu kuyinqubo yokunemba enezinyathelo eziningi edinga ubuchwepheshe kwisayensi yezinto ezibonakalayo, ukuklama isikhunta, kanye namasu okukhiqiza athuthukile.
1. Ukuklama kanye nokumodela kwe-CAD
Inqubo iqala ngomklamo wezingxenye onemininingwane, oqhutshwa yizidingo zokusebenza kanye nesitayela. Besebenzisa isofthiwe ethuthukisiwe ye-Computer-Aided Design (CAD) njenge-SolidWorks, CATIA, noma i-Siemens NX, onjiniyela badala amamodeli anembile e-3D engxenye kanye nesikhunta.
● Ukufana kobukhulu bodonga - Kuqinisekisa ukupholisa ngokulinganayo futhi kunciphisa ukugoba
● Ama-engeli okudweba – Ivumela ukukhipha izingxenye kalula esikhumbeni
● Ukusika okuphansi kanye namajiyometri ayinkimbinkimbi – Kungadinga izindlela zokubumba ezithuthukisiwe njengezenzo eziseceleni noma iziphakamisi
● Ukulungiswa kokubekwa kwesango - Izinhlelo ze-hot runner noma ze-cold runner zinciphisa amaphutha futhi zithuthukise ukugeleza
2. Ukuhlaziywa Kokugeleza Kwesikhunta Nokulingisa
Ngaphambi kokuzibophezela ekwakheni, onjiniyela benza ukuhlaziywa kokugeleza kwesikhunta besebenzisa isofthiwe yokulingisa efana ne-Autodesk Moldflow noma i-Moldex3D. Lawa mathuluzi alingisa inqubo yokubumba ngomjovo nge-inthanethi, enikeza ukuqonda okubalulekile ku:
● Isikhathi sokugcwalisa kanye nokusatshalaliswa kwengcindezi
● Izindawo zokubopha umoya kanye nezintambo zokushisela
● Ukusebenza kahle kokupholisa kanye nokulinganisa isikhathi somjikelezo
● Kungenzeka kube namabala esinki, i-warpage, noma izikhala
Ngokusekelwe emiphumeleni yokulingisa, ukwakheka kwesikhunta kuhlungwa njalo ukuze kuthuthukiswe ukubekwa kwesango, ukungenisa umoya, kanye nokuhlelwa kwesiteshi sokupholisa.
3. Ukukhethwa Kwensimbi Yamathuluzi
Ukuphila isikhathi eside kanye nokusebenza kwesikhunta kuncike kakhulu ekukhethweni kwezinto. Izikhunta ezisezingeni eliphezulu zezingxenye zesithuthuthu ezenziwe ngokwezifiso zakhiwa kusetshenziswa izinsimbi zamathuluzi ezinamandla aphezulu:
● P20 – Insimbi eqiniswe kusengaphambili enikeza ukusebenza kahle kanye nokuqina okuhle
● H13 – Ukuqina okukhulu kokushisa kanye nokumelana nokukhathala kokushisa ukuze kukhiqizwe ngobuningi obukhulu
● Insimbi Engagqwali ye-S136 – Ukumelana nokugqwala okuhle kakhulu kanye nokupholisha ukuze kuqedwe ngokukhazimula okuphezulu
Izikhunta zensimbi zithandwa kakhulu ekukhiqizweni okuphezulu ngenxa yokuqina kwazo okuphezulu kanye nobude bazo.
4. Umshini Wokuchwephesha we-CNC Oqondile
Umshini wokulungisa i-Computer Numerical Control (CNC) ubalulekile ekufezeni ukunemba ekwenzeni isikhunta. Amasu abalulekile afaka:
● Ukugaya i-CNC okune-5-Axis – Kuvumela amajiyometri ayinkimbinkimbi kanye nokunemba okuphezulu emihumeni yesikhunta
● Imishini Esheshayo (HSM) – Yehlisa isikhathi somshini ngenkathi igcina ukubekezelelana okuqinile
● I-EDM (Imishini Yokukhipha Ugesi) – Yakha amajiyometri ayinkimbinkimbi kanye nemininingwane emincane yobuso okunzima ukuyisebenzisa ngendlela evamile
● I-Wire EDM – Ifanele ukudala imininingwane yesikhunta encane neyinkimbinkimbi
Abakhiqizi abahamba phambili basebenzisa imishini yokucubungula ethuthukisiwe okuhlanganisa imishini yokugaya ye-CNC esheshayo, imishini yokugaya, imishini yokusika ucingo, kanye nezinhlelo ze-EDM.
5. Ukupholisha, Ukulungisa Umbala, kanye Nokwelashwa Komphezulu
Kuye nge-resin kanye nokusetshenziswa kwayo, izindawo zokubumba zithola ukwelashwa okuhlukahlukene:
● Ukupholisha Izibuko - Kubalulekile ekubumbeni okukhiqiza izingxenye ezisobala njengezimbozo zezibani
● Ukuthunga – Kunezela amaphethini noma ukuqedwa ukuze kuthuthukiswe ukubamba noma ubuhle
● Izembozo – I-hard chrome plating, i-PVD, i-nickel, i-titanium nitride (i-TiN), kanye nezembozo ze-DLC zithuthukisa ukumelana nokuguguleka kanye nokuphila isikhathi eside kwesikhunta
6. Ukuqhutshwa Kwesilingo Nokuqinisekiswa Kwekhwalithi
Uma isikhunta sesikhiwe, siyavivinywa ukuze sikhiqize amasampula e-T1 (isivivinyo sokuqala). Lesi sigaba sibalulekile ekuqinisekiseni ukusebenza kwesikhunta kanye nekhwalithi yengxenye. Amasampula ayahlolwa ukuze kutholakale:
● Ukunemba kobukhulu besilinganiso kusetshenziswa iMishini Yokulinganisa Ehlanganisiwe (ama-CMM)
● Ukuqeda ubuso kanye nobuhle
● Ukulingana nokusebenza ngaphakathi kwenhlangano yesithuthuthu
● Izakhiwo zezinto ezibonakalayo ngokuhlolwa okusebenzayo
Ubukhulu obubalulekile bugcinwa ngaphakathi kuka-±0.02mm ukuqinisekisa ukulingana kwengxenye.
I-Zhejiang Yaxin Mold Abakhiqizi bezithuthuthu abahamba phambili emhlabeni bahlanganisa amashumi eminyaka olwazi nobuchwepheshe obusezingeni eliphezulu ukuze banikeze izikhunta ezihlangabezana nezidingo ezibaluleke kakhulu zokunemba, ukuqina, kanye nokusebenza kahle. Kungakhathaliseki ukuthi kukhiqizwa nge-OEM noma kwenziwa ngokwezifiso ngemuva kwemakethe, umlingani wesikhunta ofanele wenza umehluko omkhulu phakathi kwengxenye enhle nenhle kakhulu.
✔ Isixazululo esisodwa - Kusukela ekwakhiweni komqondo kanye nokwenza isikhunta kuya ekukhiqizweni nasekuhlanganisweni, sibhekana nakho konke
✔ Iminyaka engu-20+ yesipiliyoni sesikhunta sezimoto - Irekhodi eliqinisekisiwe ngama-OEM omhlaba wonke kanye nabaphakeli be-Tier 1
✔ Imishini ethuthukisiwe – Izikhungo zomshini ze-CNC, i-EDM, kanye ne-5-axis ezinezitshalomali eziqhubekayo zesikhungo
Izindinganiso zekhwalithi zomhlaba wonke - Ukukhonza amakhasimende kulo lonke elaseYurophu, eNyakatho Melika, nase-Asia
