Chofunikira Choyesa
Kuphatikiza pakuwonetsetsa kupangidwa kwamankhwala ndi makina amakina, mayeso a hydrostatic amachitidwa m'modzim'modzi, ndikuyesa kuphulika ndi kuwongolera kumachitika. . Kuphatikiza apo, pali zofunika zina za microstructure, kukula kwambewu, ndi decarburization wosanjikiza wa chitoliro chomalizidwa chachitsulo.
Ubwino
1. Nthawi yobweretsera: Kusungirako kwakukulu kuonetsetsa kuti nthawi yochepa yobereka, makamaka masiku 5-7.
2. Kasamalidwe kamitengo: Zothandizira zomwe zilipo komanso luso lakasamalidwe lamitengo titha kupereka zofunikira kwambiri pazosowa za kasitomala.
3. Chigawo chapamwamba cha mphero: Ikhoza kupereka chiphaso chokwanira ndi zikalata zoyenerera kuti zitsimikizire zamtengo wapatali ndi chithandizo cha ma tender.
4. Dongosolo lolimba la QC: Kuyang'ana kwapadziko lonse, kuyesa kwathunthu ndikuwonetsa, kuwunika kwa gulu lachitatu
5.After service: zinthu zonse zotsatiridwa, kuyankha kwamakasitomala kumagwero
