Cold forging, yomwe imadziwikanso kuti cold volume forging, ndi njira yopangira komanso njira yopangira. Momwemonso njira yosindikizira, njira yoziziritsira yozizira imapangidwa ndi zinthu, zisankho ndi zida. Koma zakuthupi pakukonza masitampu nthawi zambiri zimakhala mbale, ndipo zinthu zomwe zimagwiritsidwa ntchito pozizira kwambiri zimakhala ndi waya wa disk. Japan (JIS) wotchedwa ozizira forging (ozizira forging), China (GB) wotchedwa ozizira mutu, kunja wononga fakitale ngati kuitana mutu.

Chitsulo kapangidwe bawuti ntchito adzakhala osiyana malinga ndi mphamvu ya ntchito zosiyanasiyana za malo ndi osiyana, ndiye bwanji kuweruza mphamvu kalasi? Kapangidwe kachitsulo kazitsulo kalasi yamphamvu: Gawo lamphamvu la bawuti lachitsulo lolumikizana ndi zitsulo ndi 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, ndi zina zotero. manambala, omwe motsatana amayimira mtengo wamakomedwe amphamvu ndi chiŵerengero cha ma flexion a zitsulo zopangira bawuti.

Pakuti wononga fasteners kupanga, pamwamba mankhwala ndi ndondomeko ndi mosapeŵeka, ogulitsa ambiri kufunsa za wononga wononga fasteners, njira ya mankhwala pamwamba, maukonde muyezo malinga ndi mwachidule za padziko wononga fasteners wamba processing njira pali eyiti mitundu. amitundu, monga: wakuda (buluu), phosphating, otentha dip zinki, dacromet, magetsi kanasonkhezereka, chrome plating, faifi tambala ndi zinki impregnation. The fastener screw surface treatment ndi kudzera mwa njira ina kupanga chophimba chophimba pamwamba pa workpiece, cholinga chake ndi kupanga pamwamba pa mankhwala kukongola, anti- dzimbiri zotsatira.
