Izizathu kunye nezisombululo zokuqhekeka komphezulu wamalungu eplastiki

1. Uxinzelelo olushiyekileyo luphezulu kakhulu

Ngokumalunga nokusebenza kwenkqubo, yeyona ndlela ilula yokunciphisa uxinzelelo olushiyekileyo ngokunciphisa uxinzelelo lwenaliti, kuba uxinzelelo lwenaliti lulingana noxinzelelo olushiyekileyo.Ngokumalunga noyilo lokubumba kunye nokuveliswa, isango elithe ngqo kunye nokulahlekelwa kwengcinezelo encinci kunye noxinzelelo oluphezulu lwenaliti lunokusetyenziswa.Isango langaphambili lingatshintshwa libe ngamasango amaninzi enaliti okanye amasango asecaleni, kwaye i-diameter yesango inokuncitshiswa.Xa uyila isango elisecaleni, isango le-convex linokusetyenziswa elinokuthi lisuse inxalenye ephukileyo emva kokubumba.

2. Ukugxininiswa koxinzelelo oluseleyo olubangelwa ngamandla angaphandle

Ngaphambi kokudiliza iinxalenye zeplastiki, ukuba indawo enqamlezileyo ye-demoulding ejection mechanism incinci kakhulu okanye inani leentonga ze-ejector alikwanelanga, indawo yeentonga ze-ejector ayinangqiqo okanye ukufakela kuthambekele, ibhalansi ihlwempuzekile, i-demoulding. i-slope ye-mold ayinelanga, kwaye ukuchasana kwe-ejection kukhulu kakhulu, ukugxininiswa koxinzelelo kuya kubangelwa amandla angaphandle, okubangelwa ukuqhekeka kunye nokuqhekeka phezu kwendawo yeplastiki.Kwimeko yezo ziphoso, isixhobo sokukhupha siya kujongwa ngononophelo kwaye silungiswe.

3. Iintanda ezibangelwa kukufakwa kwentsimbi

I-coefficient yokwandisa i-thermal ye-thermoplastic ngamaxesha angama-9-11 amakhulu kuneyentsimbi kunye namaxesha ama-6 amakhulu kune-aluminium.Ke ngoko, ukufakwa kwesinyithi kwinxalenye yeplastiki kuya kuthintela ukucutha ngokubanzi kwenxalenye yeplastiki, kwaye uxinzelelo olubangelwa kuxinzelelo lukhulu.Ubuninzi bexinzelelo olushiyekileyo luya kuqokelela malunga nokufaka kwaye lubangele ukuqhekeka phezu kwendawo yeplastiki.Ngale ndlela, ukufakwa kwesinyithi kufuneka kufudunyezwe, ngakumbi xa ukuqhekeka ebusweni beendawo zeplastiki kwenzeka ekuqaleni komatshini, uninzi lwazo lubangelwa ukushisa okuphantsi kokufakwa.

4. Ukukhetha okungafanelekanga okanye imathiriyeli ekrwada engacocekanga

Izinto ezikrwada ezahlukeneyo zinovakalelo olwahlukileyo kuxinzelelo olushiyekileyo.Ngokubanzi, i-resin engekho crystalline ithandeka ngakumbi kuxinzelelo olushiyekileyo kunye nokuqhekeka kune-crystalline resin;I-resin enomxholo ophezulu wezinto ezihlaziyiweyo inokungcola okungaphezulu, umxholo oguquguqukayo ophezulu, amandla aphantsi ezinto eziphathekayo, kwaye ijwayele ukuxinzelela ukuphazamiseka.

5. Uyilo olubi lwesakhiwo samalungu eplastiki

Iikona ezibukhali kunye neenotshi kwisakhiwo senxalenye yeplastiki ziyakwazi ukuvelisa uxinzelelo lwexinzelelo, okubangelwa ukuqhekeka kunye nokuqhekeka phezu kwendawo yeplastiki.Ngoko ke, iikona zangaphandle kunye nezangaphakathi zesakhiwo seplastiki kufuneka zenziwe kwii-arcs kunye ne-radius ephezulu ngokusemandleni.

6. Iintanda kumngundo

Kwinkqubo yokubumba inaliti, ngenxa yempembelelo ephindaphindiweyo yoxinzelelo lwenaliti kwi-mold, iintanda zokukhathala ziya kwenzeka emaphethelweni anee-angles ezibukhali kwi-cavity, ngakumbi kufuphi nemingxuma yokupholisa.Kwimeko yokuqhekeka okunjalo, jonga ngokukhawuleza ukuba umphezulu womqolo ohambelana nokuqhekeka unoqhekeko olufanayo.Ukuba ukuqhekeka kubangelwa ukubonakaliswa, ukubunjwa kuya kulungiswa ngomatshini.

Iimveliso zeplastiki eziqhelekileyo ebomini, ezifanaabapheki berayisi, oomatshini besandwich,izitya zokutya, iibhokisi zeplastiki zesidlo sasemini, iinkonkxa zokugcina,izixhobo zombhobho weplastiki, njl., inokuphepha ngokufanelekileyo iintanda zomhlaba.
