1. Chinhu chikuru chezvakajairikamachubhu esimbi asina musono ndeyekuti havana mawelding seams uye vanogona kumira kumanikidza kukuru.Chigadzirwa chacho chinogona kunge chakakandwa zvakanyanya kana kutonhora kudhonzwa.

2. Zviyero zvegomba remukati uye kunze kwemadziro epombi inotonhora yakadhirowa chaiyo yesimbi ine kushivirira kwakasimba uye roughness.

Zvimiro zveinotonhora inodhonzwa (yakakungurutswa) chaiyo simbi machubhu:

1. Iyo dhayamita yekunze idiki;

2. High precision inogona kushandiswa pakugadzirwa kwebhechi duku;

3. Cold-drawn (yakakungurutswa) yakapedzwa zvigadzirwa zvine yakakwirira chaiyo uye yakanaka yepamusoro yepamusoro;

4. Nzvimbo yepamuchinjikwa yepombi yesimbi yakanyanya kuoma;

5. Kushanda kwepombi yesimbi kwakanyanyisa, uye simbi inowedzera dense.
