Tili akatswiri popereka zida zodulira zogwira ntchito kwambiri pamakampani obwezeretsanso zinthu za rabara ndi pulasitiki. Zogulitsa zathu zimaphatikizapo masamba a pulasitiki a pelletizer, masamba odulira tsitsi, ndi odulira tsitsi matayala, abwino kwambiri podula ndi kudula bwino mitundu yosiyanasiyana ya pulasitiki yofewa ndi yolimba, kuphatikizapo matayala otayidwa. Zopangidwa ndi chitsulo cha tungsten, zida zodulira izi zimadziwika ndi kuuma kwambiri, kukana kuwonongeka, komanso kukana kudula. Zimapereka m'mbali zakuthwa komanso nthawi yayitali yogwirira ntchito, kukwaniritsa zofunikira zamakampani obwezeretsanso zinthu.
