Application:
SPCC/SPCCT: Zvakajairwa & General Kushandisa; Hunhu: Inokodzera kukotama kugadzirisa uye nyore kudhirowa kudhirowa, ndiyo inonyanya kudiwa mhando; Zvishandiso: Mafiriji, njanji, switchboards, mabhasikiti esimbi uye zvichingodaro.
SPCD: Drawing & Stamping Use; Hunhu: Chechipiri chete kune SPCE, imhando yekutsauka kudiki kwekudhirowa simbi ndiro; Zvishandiso: Mota chassis, denga uye zvichingodaro.
SPCE/SPCF: Yakadzika Dhirowa & Stamping Shandisa; Hunhu: Zviyo zvinogadziridzwa, yakadzika yekudhirowa kuita kwakanakisa, mushure mekutsikisa kunogona kuwana nzvimbo yakanaka. Zvishandiso: Mota fender, kumashure mativi mapaneru uye zvichingodaro.
SPCG: Yakawedzera-Yakadzika Dhirowa & Stamping & Punching Shandisa; Hunhu: Yakadzika kwazvo kabhoni inotonhora yakakungurutswa simbi, yakadzika yakadzika yekudhirowa processability. Zvishandiso: Mota yemukati bhodhi, pamusoro uye zvichingodaro.
Matauriro: SPCCT vashandisi vakatsanangura giredhi reSPCC rinoda kuve nechokwadi chekuti kusimba kwesimba uye kuwedzera kwezvipenyu. SPCF, SPCG ichada kuve nechokwadi chekuti kune kusachembera (kwete nekuda kwekuitika kwekutemesa deformation yeimba), mushure mekunze kwefekitori kwemwedzi mitanhatu - ndiko kuti, SPCC, SPCD, SPCE kana yakachengetwa kwenguva yakareba, ichaita. gadzira mechanical performance shanduko, kunyanya kudzikisa kutonhora kwekutsika kuita, inofanirwa kushandiswa nekukurumidza sezvinobvira.
SPCC yakatevedzana katalog inoda kugadzirisa kuomarara uye pamusoro pepamberi paunenge uchiodha.
