Kufotokozera Kwachidule:

CRM imagwiritsidwa ntchito pakuwongolera komanso kuwongolera zida zowunikira pakuwunika Ferrotitanium.Amagwiritsidwanso ntchito poyesa ndi kutsimikizira kulondola kwa njira zowunikira.CRM ingagwiritsidwe ntchito kusamutsa mtengo woyezedwa.

Kuyesa kwa Homogeneity ndi Kuwunika Kukhazikika

Kutha kwa certification: Chitsimikizo cha CRM iyi ndichovomerezeka mpaka Januware 1, 2026.

Kulongedza ndi Kusunga

Zolemba zotsimikizika zimayikidwa m'mabotolo agalasi okhala ndi zovundikira zapulasitiki.Kulemera konse ndi 50 g aliyense.Zimalangizidwa kuti zisunge zowuma zikasungidwa.
