Umbhali: u-Selena Wong uhlaziywe: 2022-10-09

Xa umngundo weSuntime usenza iindlela zokubumba okanye imveliso yokubumba inaliti yeplastiki kubathengi, iziphene zeemveliso zeplastiki azinakuphetshwa 100%.Kukho iziphene eziqhelekileyo ezili-12 zeemveliso ezibunjiweyo zeplastiki ezibandakanya imigca yesilivere, umgca we-welding, i-bubble yomoya, i-deformation, i-flow marks, i-shot short, i-flash, i-sink mark, uphawu lokutsala, iintanda, i-ejection mark, i-runner draw wire.

1. Imigca yesilivere: Oku kubangelwa kukungomiswa ngokwaneleyo kwimathiriyeli yeplastiki phambi kokubumba inaliti.Ngokwesiqhelo, inokwenzeka kwi-T0 kwaye emva kolingo lokuqala kumzi mveliso womthengisi, ayizukwenzeka.kwinqanaba lemveliso eqhelekileyo.

2. Umgca we-Welding / umgca odibeneyo: Lo ngumgca omncinci kwiindawo ezibunjiweyo zeplastiki.Ibonakala kwimveliso eyenziwe ngesitofu sokungunda esinamanqaku amaninzi esitofu.Xa izinto ezinyibilikayo zidibana, umgca we-welding / umgca wokudibanisa uphuma.Idla ngokubangelwa bubushushu bokungunda obahlukileyo okanye iqondo lobushushu lezinto ezisezantsi kakhulu.Ifumaneka ngokulula kwiindawo ezinkulu ezibunjiweyo zeplastiki kwaye ayinakusonjululwa ngokupheleleyo, kuphela inokwenza okusemandleni ukuyiphelisa.

3. Iqamza lomoya: Iqamza lomoya sisikhewu esidalwe ngaphakathi kodonga lwemveliso ebunjiweyo egqityiweyo.Ayinakubonwa ngaphandle kwiindawo ezingacacanga ukuba awuyinqumli.Umbindi wodonga olungqingqwa yindawo ephola kancinci, ke ukupholisa ngokukhawuleza kunye nokuncipha kuya kutsala imathiriyeli ekrwada ukwenza i-voids kwaye yenze amaqamza omoya.Amaqamza omoya acace gca kwiindawo ezicacileyo.Iilensi ezingafihliyo kunye nezibane zesikhokelo ezingafihliyo ezinokuthi zenzeke.Ke, xa sifumana ubukhulu bodonga bungaphezulu kwe-4 ~ 5mm, kuya kuba ngcono ukutshintsha uyilo lwamalungu eplastiki.

4. Ukuguqulwa/ ukugoba:Ngexesha lokutofa, i-resin ngaphakathi thi-mold yenza uxinzelelo lwangaphakathi ngenxa yoxinzelelo oluphezulu.Emva kokudiliza, ukuguqulwa kunye nokugoba kubonakala kumacala omabini emveliso egqityiweyo.iqokobhe elibhityileyo elide imveliso ezibunjiweyo kulula kakhulu ukuba deformation / ukugoba.Ke, xa kusenziwa uyilo lwenxalenye, abaqulunqi kufuneka batyebe ubukhulu bodonga.Xa abaqulunqi be-Suntime benza uhlalutyo lwe-DFM, siya kufumana umcimbi kwaye sinikeze iingcebiso kubathengi ukuba batshintshe udonga olungqingqwaukuqinisa okanye ukwenza iimbambo eziqinisayo.

5. Amanqaku okuhamba:Xa imathiriyeli yeplastiki iqukuqela kumgodi wokungunda, kuvela imibimbi emincinci emile okwesangqa ejikeleze isango kwindawo ethile.Isasazeka malunga nendawo yokutofa kwaye imveliso ye-matte ibonakala kakhulu.Le ngxaki yenye yezona ngxaki zinzima ukoyisa kwimiba yembonakalo.Ke ngoko, uninzi lweefektri zokungunda ziya kwenza indawo yokutofa ibekwe kwindawo yembonakalo ukuze kuncitshiswe le ngxaki.

6. Ishoti emfutshane:Kuthetha ukuba imveliso ebunjiweyo ayigcwaliswanga ngokupheleleyo, kwaye kukho iindawo ezingekhoyo kwinxalenye.Le ngxaki inokuphuculwa ngaphandle kokuba uyilo lokubumba alufaneleki.

7. I-Flash/ Burrs:Isibane siqhele ukwenzeka malunga nendawo yomgca wokwahlula, izikhonkwane zokukhupha, izilayidi/izinyusi kunye nezinye iindawo ezidityanisiweyo zokufaka.Ingxaki ibangelwa ngumba wofakelo lokungunda okanye uxinzelelo oluphezulu kakhulu okanye ubushushu obuphezulu bokungunda ekubumbeni inaliti yeplastiki.Iingxaki ezinjalo zinokuconjululwa ekugqibeleni.

8.Inqaku leSinki:Ngenxa yokuncipha kwe-resin, umphezulu unamanqaku angenanto kwindawo yodonga olungqingqwa lwemveliso ebunjiweyo.Le ngxaki kulula ukuyifumana.Ngokubanzi, ukuba ngaba i-pressi-ure drops, amathuba okucutheka kuya kuba mkhulu.Ingxaki enjalo kufuneka ixoxwe kwaye isonjululwe ngokusekwe kwindibaniselwano yokujonga uyilo lokungunda, ukwenziwa komngundo kunye nokubumba inaliti.

9. Tsala uphawu:Le ngxaki idla ngokubangelwaIdrafti ye-engile ayonelanga okanye amandla ecala eliphambili lokutsala imveliso ayinamandla njengaleyo yecala lomngxuma kunye nophawu lotsalo lwenziwa ngumgodi.

 Isisombululo esithe rhoqo:

1. Yongeza i-engile yoyilo ngakumbi.

2. Yenza ngakumbi ukugulisa kumngxuma/engundoqo.

3. Khangela ukuba uxinzelelo lwenaliti lukhulu kakhulu, lungisa iparamitha yokubumba ngokufanelekileyo.

4. Umngxuma olungileyo / intsimbi engundoqo yokuncipha okuncinci

10. Iintanda:Ukuqhekeka sisiphako esiqhelekileyo kwiimveliso zeplastiki, ezibangelwa ikakhulu kuxinzelelo loxinzelelo oluqhelekile kuxinzelelo olushiyekileyo, uxinzelelo lwangaphandle.kunye nokuguqulwa koxinzelelo olubangelwa yimeko yangaphandle.

11. Uphawu lokukhupha:Izizathu eziphambili ze-eIimpawu zejector zezi: uyilo olungafanelekanga lwendawo yokukhupha, ukubamba uxinzelelo olukhulu kakhulu, ukubamba ixesha loxinzelelo ixesha elide, ukupolisha okunganelanga, iimbambo ezinzulu kakhulu, i-angle eyidrafti eyaneleyo, ukukhutshwa okungalinganiyo, indawo yoxinzelelo engalinganiyo njalo njalo.

12. Iplastiki izotywe ngocingo olukwimbaleki: Isizathuukuba kwenzeke ngocingo olutsalweyo lweplastiki lubushushu obuphezulu kumlomo okanye iingcebiso ezishushu.
