I-LDPE iyagaywa kabusha, futhi ukugaywa kabusha ngomshini kukhiqiza i-resin esebenzisekayo evela emisindweni ehlanzekile yangemva kwezimboni nangemva kokusetshenziswa. I-Dongguan Hanxin inikeza izinketho zokuqukethwe okugaywe kabusha ezinhlelweni lapho izinhloso zokusimama noma imithetho zikufuna. Amabanga agaywe kabusha ahlolwa ukuze afane, ukuze asebenze ngendlela elindelekile emishinini ejwayelekile yokucubungula.

Qala ngokuchaza inqubo, ukuqina noma ukuthambileka okudingekayo, kanye nendawo yokusetshenziswa kokugcina. Inkomba yokuncibilika ilawula ukuhamba nokuziphatha kwe-extrusion, ukuminyana kuthonya ukuguquguquka nokusebenza kwesithiyo, futhi izithako zinquma ukumelana ne-UV, ukushelela, noma ukuvimbela umlilo. Ukuhlola isampula emgqeni wakho wangempela wokukhiqiza iyona ndlela ethembekile yokuqinisekisa ukukhetha.

Ukulawulwa kwekhwalithi kuqala ngokuhlolwa kwezinto zokusetshenziswa ezingenayo okubandakanya ukuhamba kwe-melt, ukuminyana, umswakama, nokungcola. Izikhathi zangaphakathi ziqapha izinga lokushisa, umkhiqizo, ukusabalalisa, nokufana kombala, kuyilapho ukuhlolwa kokugcina kuqinisekisa amandla okudonsa, ukunwebeka, kanye nokusebenza komthelela. Amarekhodi e-batch agcina ukulandeleka, futhi izinto ezingahambisani nazo ziyahlukaniswa kunokuba zithunyelwe.

Xhumana neDongguan Hanxin Plastic Technology Co., Ltd. ngefomu lokubuza kuwebhusayithi, i-imeyili, noma ucingo nemaki yakho oyifunayo, ukusetshenziswa, kanye nevolumu yanyanga zonke. Ithimba lizophendula ngentengo, izinketho zamasampuli, kanye nesheduli yokulethwa. Ukubonisana kwezobuchwepheshe mayelana nokwakheka nokucubungula kuyatholakala mahhala ngesikhathi sesigaba sokuhlola.
