Daim ntawv thov:
SPCC/SPCCT: Siv dav & Siv dav; Cov yam ntxwv: Haum rau kev khoov kev ua haujlwm thiab kev sib sib zog nqus ua kom yooj yim, yog qhov xav tau ntau yam; Daim ntawv thov: tub yees, rails, switchboards, hlau pob tawb thiab lwm yam.

SPCD: Kos duab & Stamping siv; Cov yam ntxwv: Qhov thib ob tsuas yog rau SPCE, yog qhov zoo ntawm qhov sib txawv me me ntawm daim duab kos hlau phaj; Daim ntawv thov: Tsheb chassis, ru tsev thiab lwm yam.

SPCE / SPCF: Sib sib zog nqus kos & siv stamping; Cov yam ntxwv: Cov nplej tau hloov kho, kev sib sib zog nqus nqus tau zoo heev, tom qab stamping tuaj yeem tau txais qhov chaw zoo nkauj. Daim ntaub ntawv: Tsheb fender, rear sab panels thiab hais txog.

SPCG: Kev kos duab sib sib zog nqus & stamping & Punching siv; Yam ntxwv: Tsawg carbon txias dov hlau, zoo heev sib sib zog nqus nqus processability. Daim ntaub ntawv: Tsheb sab hauv board, nto thiab lwm yam.

Lus Cim: SPCCT yog cov neeg siv teev cov qib ntawm SPCC uas yuav tsum tau xyuas kom meej tias lub zog tensile thiab extensibility ntawm hom. SPCF, SPCG yuav tsum xyuas kom meej tias tsis muaj kev laus (tsis yog vim qhov tshwm sim ntawm tensile deformation ntawm cov cuab yeej), tom qab sab nraud Hoobkas rau 6 lub hlis - uas yog, SPCC, SPCD, SPCE yog khaws cia ntev, yuav tsim cov kev hloov pauv hloov pauv, tshwj xeeb tshaj yog txhawm rau txo qhov txias stamping kev ua tau zoo, nws yuav tsum tau siv sai li sai tau.

SPCC series catalog yuav tsum tau ua kom muaj zog thiab nto ua ntej thaum xaj.

FC: kev ua tiav saum npoo zoo: Sab zoo dua ntawm cov hlau phaj yuav tsum tau txwv ntxiv rau qhov tsis xws luag, tsis muaj qhov pom tseeb tsis xws luag, sab nraud yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm FB.

FD: ntxiv-advanced nto tiav: Sab zoo dua ntawm cov hlau phaj yuav tsum tau txwv ntxiv rau qhov tsis xws luag, uas yog, tsis cuam tshuam rau cov tsos ntawm cov xim los yog tom qab plating zoo, lwm sab yuav tsum tau raws li FB nto yuav tsum tau.
