Kuvimbiswa kwehutano
1. Inopinda Raw Material Inspection
2. Raw Material Segregation kudzivirira simbi giredhi kusanganiswa-up
3. Kupisa uye Hammering End yeCold Drawing
4. Cold Drawing uye Cold Rolling, pamutsetse wekuongorora
5. Kurapa Kupisa, +A, +SRA, +LC, +N, Q+T
6. Kururamisa-Kucheka kune yakatarwa kureba-Yakapedzwa Kuyera Kuongorora
7. Mechanical Testing mumalabhu ako ane Tensile Simba, Goho Simba, Elongation, Kuoma, Impact,
Microinstruction nezvimwe
8. Packing uye Stocking
Application
DIN1630 hydraulic steel chubhu inowanzoshandiswa mumhando dzakasiyana-siyana dze hydraulic uye pneumatic, senge mu hydraulic cylinders, hydraulic lines, uye mamwe ma-high-pressure applications.
Inoshandiswa zvakanyanya mumaindasitiri akadai semotokari, aerospace, kuvaka, uye muchina, uko kurongeka uye kuvimbika kwakakosha pakushanda pasina musono.
Product package
ew Gapower Metal inyanzvi inogadzira hydraulic simbi pombi.Nekugadzirwa kwepagore kwematani gumi ezviuru zvemhando yepamusoro yesimbi isina musono chubhu.
uye matani 20 000 esimbi yakakwenenzverwa uye inopisa yakamonereka.
