Ngokuvamile, iqoqo lesikhunta lakhiwa izingxenye ezintathu: isikhunta esihle, isikhunta sesikhunta kanye nomkhono wesikhunta. Isikhunta esihle sakhiwe ibhande elisebenzayo, ummese ongenalutho, i-deflector nezinye izingxenye. Ingxenye ngayinye inomsebenzi wayo. Okulandelayo yi-lungisa kabusha i-aluminium.Sazise umsebenzi walezi zingxenye.

①Ibhande lokusebenza: Indawo yokusebenza yebhande lokusebenza i-perpendicular endaweni yokusebenza yesikhunta. Inhloso ukulungisa usayizi wephrofayela. Ide kakhulu noma imfushane kakhulu ayifaneleki. Idizayini yebhande lokusebenza kufanele icabangele umehluko wokuqina kodonga lwephrofayili, ibanga ukusuka enkabeni kanye nengxenye lapho umgodi wokufa umbozwe ibhuloho le-shunt, njll.

②Ummese ongenalutho: Yisiteshi esikhulu samaphrofayili e-aluminium ukuze adlule. Kuyilungu lesakhiwo elisekelwa i-cantilever ekugcineni kwebhande elisebenzayo le-die hole, elingaqinisekisa ikhwalithi yephrofayili kanye nempilo yesevisi ye-die.

③Ipuleti le-Baffle: Kudingeka kube nenqubo yokuguqulwa kunqubo ukusuka ku-aluminium rod ukuya kuphrofayela. Ipuleti le-baffle linganciphisa inani le-deformation futhi lidlale indima yokuma kwenguquko.

④Imbobo ehlukanisiwe: Ngemuva kokuthi ingxubevange ye-aluminium idlule inqubo engenhla, iqala ukungena embobeni ehlukanisiwe ukuze iqhubeke nokucacisa umumo wesigaba esiphambene nosayizi wephrofayela.

⑤Isikhunta core: Thola umumo nosayizi we-cavity ngaphakathi.

⑥Igumbi lokushisela: Ngemva kokuthi wonke umsebenzi wokulungiselela ususendaweni, ingxubevange ye-aluminium iqala ukungena egumbini lokushisela ngesiteji sokugcina se-extrusion.
