China OEM mwambo mpweya zitsulo castings ndianataya sera ndalama kuponyera ndondomeko.Titha kupereka 3.1 Satifiketi Yopangira zitsulo zotayira malinga ndi EN 10204 ngati mukufuna. Njira zowunikira zomwe zilipo: kuyezetsa miyeso ndi CMM, kuyesa kosawononga, kapangidwe ka mankhwala, makina, kuyezetsa kuuma, kusanja kokhazikika, kusinthasintha kwamphamvu, kuthamanga kwa mpweya komanso kuthamanga kwamadzi.
Malinga ndi mlingo wa carbon zili, mpweya zitsulo poponya zambiri ogaŵikana otsika mpweya zitsulo, sing'anga mpweya zitsulo ndi mkulu mpweya zitsulo. Zitsulo za kaboni zamayiko onse padziko lapansi nthawi zambiri zimasankhidwa molingana ndi mphamvu zawo, ndipo magiredi ofanana amapangidwa.
Ponena za mankhwala a carbon steel, kupatulapo phosphorous ndi sulfure, palibe zoletsa kapena malire apamwamba pa zinthu zina za mankhwala. Pansi pa zomwe tafotokozazi, kapangidwe kake kachitsulo ka kaboni kachitsulo kamatsimikiziridwa ndi mazikowo malinga ndi zomwe zimafunikira makina.
Njira zochizira kutentha zopangira zitsulo za kaboni nthawi zambiri zimakhala zokhazikika, zokhazikika kapena zokhazikika + zotentha. Kwa ena apamwamba mpweya zitsulo castings, quenching ndi tempering angagwiritsidwenso ntchito, mwachitsanzo, quenching + mkulu kutentha tempering, kuti patsogolo mabuku mawotchi zimatha castings mpweya zitsulo. Zitsulo zazing'ono za carbon zitsulo zimatha kuzimitsidwa mwachindunji ndi kutenthedwa kuchokera ku dziko la as-cast. Kwa zazikulu kapena zovuta zooneka ngati carbon steel castings, ndi koyenera kuchita quenching ndi kutentha mankhwala pambuyo normalizing mankhwala.
