Umhlinzeki othembekile we-OEM casting metal unikeza ukwesekwa okuphelele kobunjiniyela:

• Kusukela ku-prototype kuya ekukhiqizeni kwevolumu: Amasevisi okusakaza ensimbi angokwezifiso avumela amaklayenti ukuthi akhe imikhiqizo emisha ngokuzethemba. I-prototyping esheshayo (amaphethini aphrintiwe we-3D-noma ukusakaza kwesihlabathi okusheshayo) kusheshisa ukuqinisekiswa kwedizayini. Uma umklamo usuphothuliwe, ithuluzi lokukhiqiza lenzelwe amandla adonsela phansi, ukubumba amagobolondo, noma ukutshala imali.

• Usekelo lobunjiniyela: Isofthiwe yokulingisa (imodeli yokuqinisa, ukuhlaziya ingcindezi) ibikezela amaphutha futhi ithuthukise ukuklama kwesango/isikhuphukeli. Ukubonisana nge-Metallurgical kuqinisekisa ukukhetha okulungile kwe-alloy—kungakhathaliseki ukuthi izingxenye zemishini yensimbi eyi-ductile ezidinga ubude obuphakeme noma izingxenye zemishini yensimbi empunga ezidinga ukumanziswa.

• Amakhono ayingqayizivele: Ezingxenyeni zemishini ye-iron ductile, umenzi ulawula i-nodularity (imvamisa>85% nodularity) ngokujova ngokucophelela. Ezingxenyeni zensimbi ezibunjiwe zegobolondo, imishini yephethini enembile iqinisekisa ukuphindaphinda.

5.3 Uthembekile umphakeli & umkhiqizo iphothifoliyo

Imboni ethembekile yezingxenye zensimbi yaseChina inikeza iphothifoliyo ebanzi:

• Ibanga eligcwele: Izingxenye ze-iron cast cast iron, igobolondo lokubumba izingxenye zensimbi ezisansimbi, ukubunjwa kwensimbi okuyinkimbinkimbi, izingxenye zemishini yezolimo, ukubunjwa kwephampu namavalvu, izingxenye eziyisipele zesitimela sikaloliwe, iloli elisindayo nezingxenye zezimoto, nemishini yokubopha ihadiwe.

• Ukulawulwa kwekhwalithi: Konke ukuncibilika kuhlaziywa nge-spectroscopy. Ukuhlolwa kwemishini (ukushuba, ubulukhuni, umthelela) kuqinisekisa izakhiwo. Ukuhlola okungabhubhisi (i-ultrasonic, izinhlayiya kazibuthe, ukungena kukadayi) kuthola amaphutha angaphakathi nangaphezulu. Ukuhlolwa kwe-Dimensional kusetshenziswa ama-CMM kuqinisekisa ukuhambisana nemidwebo.

• Ukulandeleka: Ukulingisa kuyamakwa futhi amarekhodi ayagcinwa, okunikeza ukulandeleka okugcwele kusukela ezintweni ezingavuthiwe kuya kumkhiqizo oqediwe—okubalulekile kumzila wesitimela obalulekile wokuphepha nezinhlelo zokusebenza zezimoto.

Ngokubambisana nomkhiqizi wezingxenye zensimbi ezisansimbi zekhwalithi ephezulu e-OEM enikezela ngezinsizakalo zomphakeli wensimbi ye-OEM, amakhasimende athola ukufinyelela ku-metallurgy esezingeni lomhlaba, ukuguquguquka kwenqubo, kanye nokukhiqiza okungabizi kakhulu. Noma ngabe udinga izingxenye zensimbi ezicijile zevolumu ephezulu zensimbi yokwakha noma izingxenye zensimbi ezicijile ezinembayo zemishini yezolimo, uzakwethu olungile uqinisekisa ukuthi yonke ingxenye yensimbi ekhonjiwe ihlangabezana namazinga aphezulu kakhulu ekhwalithi nokusebenza.
