1.Kuwonongeka kwa nkhungu

　　Chifukwa cha maopaleshoni achilendo (kuphwanyidwa kwachiwiri, ndi zina zotero) ndi kuchuluka kwa nkhungu, nkhungu zam'mwamba ndi zapansi zimakhala ndi zipsera kapena zosweka. Chifukwa chake, kulephera kutulutsa mawonekedwe okhazikika kungayambitse mavuto akulu ngati ma burrs. Die abnormalities angapezeke poyang'ana mbali ya crimping.

　　Terminal deformation

　　Mtundu wololeka umasiyanasiyana kutengera malo, ndipo nthawi zambiri amakhala mkati mwa ± 5°. Malo opotoka adzatulutsa chilema chofanana ndi chopindika cham'mbali.

　　2.Terminal deformation

　　Pitani mmwamba:

　　Mtundu wovomerezeka umasiyanasiyana malinga ndi ma terminals osiyanasiyana, nthawi zambiri mkati mwa 3 °. Ma terminal omwe amapindikira m'mwamba sangathe kuyikidwa mu chipolopolo. Ngakhale atayikidwa, amachoka pa msomali ndikupangitsa kusakwanira bwino mbali inayo 1.

　　Gona pansi:

　　Makona ovomerezeka amasiyana pang'ono kutengera cholumikizira, ndipo nthawi zambiri amakhala mkati mwa 3 °. Ma terminal omwe amapindika pansi sangathe kulowetsedwa mu chipolopolocho, ndipo ngakhale chipolopolocho chingalowetsedwe, msomali umachoka, ndipo izi zimapangitsa kuti pakhale kusakwanira bwino mbali inayo.
