Pikiri kɛli masin kuru ye masin yɔrɔ koloma dɔ ye, a bɛ kɛ fɔlɔ ka plastiki fɛnɲɛnamafagalanw lase, k’u sɔgɔ, k’u wuli, ani k’u degun. A jɔcogo n’a baarakɛcogo bɛ nɔ bila plastiki kɛcogo ɲuman na ani a ka fɛn dilannenw ka ɲumanya la.
Kurukuru farikolo bɛ kɛ ni baloyɔrɔ ye, degun yɔrɔ ani homogenization yɔrɔ. Balo yɔrɔ bɛ kɛ ka fɛnɲɛnamafagalan gɛlɛnw sumaya ka kɔn o ɲɛ ani k’u lase; degun yɔrɔ bɛ se ka wuli, ka ɲagami, ani ka fiɲɛbɔ; ani homojenizasiyɔn dakun bɛ a to sɔgɔsɔgɔninjɛ funteni ni jibɔ sabatili bɛ kɛ kelen ye. Ka da danfara kan plastiki cogoyaw la, juruw bɛ se ka tila suguya saba ye: gradient suguya (min bɛnnen don funteni-fɛnw ma minnu bɛ se ka fɛnw sɛgɛsɛgɛ i n’a fɔ PVC), abrupt suguya (min bɛnnen don poliyolefiniw ma), ani general-purpose suguya. Danfaraba min bɛ o ni ɲɔgɔn cɛ, o bɛ sɔrɔ degun yɔrɔ janya ni a tigɛcogo la. Paramɛtɛrɛ jɔnjɔnw ye cɛmancɛ, ɲɛda hakɛ ani degun hakɛ ye, minnu ka kan ka bɛn fɛnw cogoyaw ma walasa ka plastiki nɔw ɲɛ. Fɛn minnu bɛ kɛ tuma caman na, olu ye fɛnw ye minnu funteni ka bon ani minnu bɛ sɛgɛn- i n’a fɔ 38CrMoAla sɔgɔlen ani tungsten carbide nickel-based alloy.
