Uhlelo Lokukhiqiza:
Inzuzo:
I-Raw material ivela ku-Top production ethembisa ikhwalithi ephezulu.
Ubuchwepheshe obunembile buqinisekisa ukubekezelela usayizi okuqondile.
Ithimba elisebenzayo lokuthengisa likunikeza isiphakamiso esifanele.
Umtitilizo wethimba langemuva kokuthengisa nokusekelwa kwesiqinisekiso somkhiqizo.
Ikhwalithi yokulawula:
Isevisi yethu:
