Malinga ndi mitundu yosiyanasiyana ya gating system, nkhungu pulasitiki akhoza kugawidwa mu mitundu itatu:
(1) a chachikulu nozzle nkhungu: Wothamanga ndi chipata ali pamzere wolekanitsa, ndipo nkhungu imapangidwa pamodzi ndi mankhwala pamene nkhungu imatsegulidwa, kapangidwe ndi kophweka, kukonza ndi kosavuta ndipo mtengo wake ndi wotsika, choncho, anthu ambiri amagwiritsa ntchito ntchito zazikulu za nozzle system. Pulasitiki nkhungu dongosolo lagawidwa magawo awiri: Dynamic Mold ndi nkhungu yokhazikika. Ndi gawo logwira ntchito la makina ojambulira a nkhungu zosinthika (ambiri a ejection mbali) , jekeseni kumapeto kwa makina a jakisoni nthawi zambiri sagwira ntchito yotchedwa fixed mold. Chifukwa chachikulu nozzle kufa atakhazikika mbali ya ambiri ndi mbale ziwiri zitsulo, amadziwikanso kuti mapangidwe a nkhungu ya mbale ziwiri. Kufa kwa mbale ziwiri ndiye njira yosavuta kwambiri mumphuno yayikulu.
(2) mpweya wabwino ufa: wothamanga ndi chipata osati pamzere wolekanitsa, zambiri mwachindunji mu mankhwala, kotero kupanga zambiri kuposa gulu la mzere wolekanitsa nozzle, kapangidwe ndizovuta kwambiri, kukonza zovuta kwambiri, zambiri kutengera zofunika mankhwala ndi kusankha zabwino nozzle dongosolo. The fixed die part of fine nozzle mold nthawi zambiri imakhala ndi mbale zitatu zachitsulo, kotero umatchedwanso &mawu;mbale zitatu nkhungu&mawu; . Kufa kwa mbale zitatu ndiye njira yosavuta kwambiri muzofa za nozzle.
(3) otentha wothamanga nkhungu: Mtundu uwu wa nkhungu kwenikweni ndi wofanana ndi nozzle wabwino, kusiyana kwakukulu ndikuti wothamanga ali mu mbale imodzi kapena zingapo zothamanga zotentha ndi mapampu otentha ndi kutentha kosalekeza, palibe ozizira zinthu demoulding, wothamanga ndi chipata ali mwachindunji pa mankhwala, choncho, wothamanga sayenera kugwetsa, dongosololi amatchedwanso no-nozzle system, akhoza kusunga zipangizo, oyenera zinthu zamtengo wapatali zopangira, zofunika mankhwala apamwamba, zovuta kupanga ndi processing, mtengo wokwera kwambiri. Hot Runner System, amadziwikanso kuti hot runner system, makamaka ndi ma seti otentha othamanga, hot wothamanga mbale, bokosi lowongolera kutentha. Dongosolo lathu lodziwika bwino lothamanga lotentha lili ndi chipata chimodzi chotentha komanso chipata chamitundu yambiri chamitundu iwiri. Chipata chimodzi chotentha chimagwiritsidwa ntchito kubaya pulasitiki yosungunula molunjika mu nkhungu ndi mkono umodzi wotentha, yomwe ili yoyenera nkhungu ya pulasitiki yokhala ndi chitseko chimodzi ndi chipata chimodzi Chipata chotentha chamitundu yambiri chimagwiritsidwa ntchito kuyika zinthu zosungunuka m'zitsamba zosiyana za zipata zotentha kenako ndikulowa mu nkhungu kudzera pa mbale yothamanga yotentha..
Malingaliro a kampani FLYSE Plastic Machinery Co., Ltd ali 15 zaka’ luso kupanga mitundu yonse ya makina pulasitiki jekeseni akamaumba ngati zotchipa, magwiridwe antchito apamwamba, liwilo lalikulu, mitundu yambiri, PET, Zithunzi za PVC, etc.. FLYSE Plastic Machinery ingathandizenso makasitomala kusankha njira yoyenera ndikugula nkhungu zolondola kuchokera ku China.
