Cross flange self tapping screw

Zvishandiso uye Kurapa Kwepamusoro

Zvinhu zvakajairika

Carbon simbi: Mutengo wakaderera, simba rakakwirira, pamusoro zvinoda ngura kudzivirira kurapwa, senge galvanizing uye Dacromet.

Simbi isina tsvina (304/316): Yakasimba corrosion resistance, yakakodzera kune hunyoro kana makemikari nharaunda.

Aluminium alloy / mhangura: Huremu kana conductive zvinodiwa mamiriro, asi nesimba rakaderera.

Surface Treatment

Galvanization: yakakamurwa kuita electroplating (yebhuruu uye chena zingi, ruvara zingi) uye inopisa-dip galvanizing, kazhinji inodzivirira ngura, inokodzera nharaunda dzemukati.

Dacromet (zinc chromium coating): Hapana njodzi yehydrogen embrittlement, yakakwirira tembiricha kuramba, corrosion kuramba, inoshandiswa mumotokari uye kunze.

Phosphating: inowedzera lubricity uye inoderedza kuisa friction.

Nylon coating: insulation, anti kusunungura, inowanzoshandiswa mumidziyo yemagetsi.

Minda Yekushandisa

Kugadzira mota: Mashizha esimbi zvikamu, mapaneru emukati, uye wiring harness fixation inofanirwa kumisa kuvhunduka uye anti kuregedzera.

Zvishandiso zvemagetsi: Circuit board uye shell assembly, kunyanya diki diki (M2-M4) kudzivirira kupindira kwekuitisa.

Architectural decoration: Kuiswa kwemavara esimbi mahwendefa, aruminiyamu alloy magonhi nemahwindo, uye kuchengetedzwa kwenzvimbo yeflange kubva kune zvikwambo.

Mechanical midziyo: mapaneru uye akavharirwa akamisikidzwa kuti amirire nharaunda yekuzunguza.

Zvinotsanangurwa uye zviyero
