(1) Gabatarwatwin-screw extruder
Twin-screw extruder ya haɗa da tsarin masu zuwa.Tsarin dunƙule galibi yana kammala aikin filastik da isar da kayan aiki, wanda ke da babban tasiri akan aiki da ingancin samfuran da aka gama.
① Tsarin ciyarwa: gami da hopper, motsa jiki, da injin ciyarwa.Zai iya hana tarin kayan abu kuma ya sauƙaƙe shigarsa cikin santsi cikin tashar abinci.
② Tsarin dumama na waje: Yawanci amfani da sandar dumama da Silinda don dumama kayan da kyau da kuma inganta aikin filastik.
③Tsarin sanyaya: Ana amfani da tsarin musayar zafi wanda ya ƙunshi mai ko ruwa don rage zafi na fuselage, don sarrafa yanayin zafin silinda yadda ya kamata.
④ Tsarin canza yanayin allo na hydraulic: Yi amfani da allon tacewa mai maye gurbin don tsangwama da ƙazanta, haɓaka matakin filastik, da tabbatar da daidaito da kwanciyar hankali na ingancin kayan fitarwa.
