Pombi yakarongedzerwa pasi peiyi dhizaini ndeyekumanikidza sevhisi pane inokwana tembiricha ye350 ℃.
Pombi isina kuvharwa, yakasviba yakasviba kana inopisa dip zinc-yakashongedzwa (yakagadzirirwa);
Mumisumbu ine zvipfuramabwe zviviri zvedonje;
Zvose zvinopera nevadziviriri vekupedzisira;
Magumo akajeka, bevel end (Kana zvichidiwa nemutengi uye S≤22mm, pombi yekupedzisira inofanira kuvharwa, dhigirii: 30 ° (+5 ° ~ 0 °), uye ukobvu hwemadziro emudzi hautapudzwe ne <2.4 mm);
