Isingeniso: Njengochwepheshe wamazinyo emkhakheni wodokotela wamazinyo wobuhle, ukuqonda isayensi yemikhiqizo ehlukahlukene yamazinyo kubalulekile. Omunye umkhiqizo onjalo, amatreyi we-thermoplastic, udlala indima ebalulekile ekuletheni ukwelashwa kwamazinyo okuphumelelayo. Le ndatshana izodlulisela emhlabeni wamathilreyi we-thermoplastic, inikeze ukuqonda okubalulekile ngokusetshenziswa kwabo, izinzuzo, kanye nezici eziveza
