Ukubumba okubandayo, okwakwaziwa ngokuba kukwenziwa komthamo obandayo, yinkqubo yokuvelisa kunye nendlela yokulungisa. Ngokusisiseko iyafana nenkqubo yokunyathela, inkqubo yokubumba ebandayo iqulunqwe ngezinto, iimolds kunye nezixhobo. Kodwa imathiriyeli ekusetyenzweni kwesitampu ubukhulu becala yipleyiti, kwaye imathiriyeli ekusetyenzweni okubandayo kokubunjwa ngocingo lwediski. I-Japan (i-JIS) ebizwa ngokuba yi-cold forging (i-cold forging), i-China (i-GB) ebizwa ngokuba yi-cold heading, ngaphandle kwe-screw factory efana nokubiza intloko.

Ibholithi yesakhiwo sentsimbi esetyenziswayo iya kwahluka ngokwamandla okusetyenziswa okwahlukileyo kwendawo ikwahlukileyo, ngoko ke ukugweba njani ibakala lamandla? Isakhiwo sentsimbi sibholithi ibakala lokuqina: Ibakala lamandla lebholithi yesakhiwo sentsimbi yoqhagamshelo lwesakhiwo sentsimbi yi-3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, njl njl. amanani, ngokulandelelana amele ixabiso le-tensile lamandla kunye nomlinganiselo we-flexion we-steel structure bolt material.

Ukuveliswa kwe-screw fasteners, unyango lomphezulu yinkqubo engenakuthintelwa, abathengisi abaninzi ekubuzeni malunga ne-screw fasteners, indlela yonyango lomphezulu, umgangatho womnatha ngokolwazi olushwankathelweyo malunga nomphezulu we-screw fasteners iindlela eziqhelekileyo zokuqhuba kukho iindidi ezisibhozo. iifom, ezifana: omnyama (oluhlaza okwesibhakabhaka), i-phosphating, i-hot dip zinc, i-dacromet, i-galvanized electric, i-chrome plating, i-nickel kunye ne-zinc impregnation. I-fastener screw yonyango lomphezulu yindlela ethile yokwenza umaleko wokugquma phezu kwendawo yokusebenza, injongo yayo kukwenza umphezulu wemveliso ibe mhle, i-anti-corrosion effect.
