- Kugadzira kwakasarudzika pamifananidzo
11. Sei Uchifanira Kusarudza Simbi Yevakadzi?
- Mukati meLabhoritari yeR&D & QA
- Kugara kwenguva refu kwezvinhu zvakagadzirwa kunoita kuti zvinhu zvisvike kwenguva pfupi
- Makumi emakore eruzivo rwesimbi, kunyanya muzvishandiso zvinopisa zvakanyanya
- Kunyatso tevera uye magwaro ekuti michina yekumanikidza inoenderana sei nezvinodiwa
- Mupi wemhinduro imwe chete wekutenga, kugadzirisa, uye kutumira kunze kwenyika masisitimu emapombi esimbi isina ngura
Kuti muwane ruzivo rwehunyanzvi, mitengo, uye mitengo yemapurojekiti akagadzirwa, taurai neWomic Steel nhasi. Tagadzirira kutsigira zvinodiwa zvenyu zvemapombi zvine hungwaru, nekukurumidza, uye kuvimbika.
Sarudza Womic Steel Group semubatsiri wako wakavimbika weMachubhu eSimbi Isina Zvisimbisouye kushanda zvakanaka kwekutumira zvinhu. Tinokugamuchirai!
