Thechingwe chomengaimapindidwa ndikulukidwa ndi makina azingwe aminga.Anthu omwe amadziwika kuti iron tribulus, waya waminga, minga minga.

Mtundu wazinthu: screw single ndi screw double.Zopangira: zapamwamba za carbon lowwaya wachitsulo.Ukadaulo wochizira pamwamba: electrogalvanizing, galvanizing otentha, pulasitiki yokutidwa (nthawi zambiri wobiriwira).Ntchito: yogwiritsidwa ntchito pakulekanitsa ndi kuteteza malire a udzu, njanji ndi mayendedwe.

Kugawa ndi njira yokhotakhota
Pali njira zitatu zothetsera vutolichingwe chomenga: kupotoza kwabwino, kupotoza kumbuyo, kupotoza kwabwino ndi koyipa.
Njira yokhotakhota: ndi yokhota mawaya awiri kapena kuposerapo kukhala chingwe chawaya wapawiri kenaka kupotoza chingwe cha mingamo kuzungulira mawayawo.
Njira yokhotakhota mosintha: ndi yopota waya wa mingamo kuzungulira waya waukulu (ndiko kuti, waya umodzi) kenaka kuwonjezera waya ndi kuukhotetsa kukhala chingwe cha minga iwiri.
Njira yabwino komanso yolakwika yopotoka: ndi mbali yotsutsana ndi njira ya waya waukulu wokhotakhota kuchokera ku waya.Sizinapotozedwa mbali imodzi.
Zithunzi za PVCchingwe chomengamankhwala pamwamba ndi kulimbikitsa odana ndi dzimbiri mphamvu, kutalikitsa moyo utumiki.Chingwe chotchinga chagalasi monga momwe dzinalo limatanthawuzira kuti mankhwala apamtunda ndi malata, amatha kukhala ndi malata amagetsi komanso malata otentha;Waya waminga wa PVC wochizira pamwamba ndi pulasitiki wa PVC wokutidwa, waya wamingamo mkati mwa waya wakuda, waya wa electroplating ndi waya wotentha.
