Umshini ungumshini wenqubo osetshenziswa kabanzi ekukhiqizeni ukulungiswa okuqinile embonini yezemithi.Inemisebenzi ehlanganisa ukuxuba, i-granulating, njll. Isetshenziswe kabanzi ezimbonini ezifana nemithi, ukudla, imboni yamakhemikhali, njll.

Kwenziwe ngensimbi engagqwali yekhwalithi ephezulu ye-austenitic, wonke amakhona ane-arc eguquliwe, awekho amaphethelo afile, awekho izinsalela, awekho indawo ekhonkolo kanye ne-convex, nezikulufu eziveziwe.
Ingaphakathi nangaphandle licwebezeliswe kakhulu.Ubukhulu obungaphakathi bufinyelela ku-Ra≤0.2μm.Ubuso obungaphandle buphathwa nge-matte finish, futhi ukugoqa kufinyelela ku-Ra≤0.4μm, okulula ukuyihlanza.
Uhlelo lokulawula lwe-PLC, ukusebenza kungaqedwa ngokuzenzakalela ngokuya ngezidingo zomsebenzisi ngokusetha imingcele yenqubo.Yonke imingcele yenqubo ingaphrintwa ngokuzenzakalelayo, futhi amarekhodi okuqala ayiqiniso futhi anokwethenjelwa.

Hlangana nezidingo ze-GMP zokukhiqizwa kwemithi.
