Ukanda wa Shaba
Utangulizi wa Bidhaa
Karatasi ya Shaba inayotokana na shaba ya kielektroniki, zinki na kufuatilia vipengele kama malighafi, kupitia usindikaji kwa ingot, kuviringisha moto, kuviringisha baridi, matibabu ya joto, kusafisha uso, kukata, kumalizia na kisha kufungasha. Utendaji wa michakato ya nyenzo, plastiki, mali ya mitambo, upinzani wa kutu, utendaji na bati nzuri. Imetumika sana katika umeme, magari, mawasiliano, vifaa, mapambo na tasnia zingine
