Ungawafumana njani amalungu eplastiki enziwe kakuhle

1. Ukukhetha imathiriyeli ekrwada

Kukho iintlobo ezininzi ezahlukeneyo zeplastiki kwimarike, kodwa ayizizo zonke ezinokuthi zibekwe, njengoko iplastiki nganye ineepropati zayo, kwaye xa i-plating kufuneka ithathele ingqalelo ibhondi phakathi kweplastiki kunye nomaleko wesinyithi kunye nokufana phakathi kweempawu ezibonakalayo. iplastiki kunye nentsimbi.Iiplastiki ezifumanekayo ngoku ukuze zibekwe yi-ABS kunye ne-PP.

2.Imilo yamalungu

A).Ubukhulu becala leplastiki kufuneka bufanane ukuze kugweme ukungalingani okubangela ukuncipha kwenxalenye yeplastiki, xa i-plating igqityiwe, i-metallic luster yayo ibangela ukuncipha ngokucacileyo kwangaxeshanye.

Kwaye udonga lwenxalenye yeplastiki akufanele lube luncinci kakhulu, ngaphandle koko luya kukhubazeka ngokulula ngexesha lokutyalwa kwaye i-bonding ye-plating iya kuba yimbi, ngelixa ukuqina kuya kuncitshiswa kwaye i-plating iya kuwa ngokulula ngexesha lokusetyenziswa.

B).Gwema izimbobo ezingaboniyo, ngaphandle koko isisombululo sonyango esisele kwi-solenoid eyimfama asiyi kucocwa lula kwaye siya kubangela ukungcola kwinkqubo elandelayo, ngaloo ndlela kuchaphazela umgangatho we-plating.

C).Ukuba i-plating ibukhali, i-plating iya kuba nzima ngakumbi, njengoko imiphetho ebukhali ayiyi kubangela ukuveliswa kwamandla kuphela, kodwa ibangela ukuba i-plating ibe ne-bulging kwiikona, ngoko kufuneka uzame ukukhetha inguqu yekona ejikelezileyo kunye ne-radius. ubuncinane 0.3mm.

Xa utyabeka iinxalenye zeplastiki ezisicaba, zama ukutshintsha inqwelomoya ibe yimilo engqukuva kancinane okanye wenze umphezulu we-matt wokwaleka, kuba imilo eyisicaba iya kuba neplating engalinganiyo enombindi obhityileyo kunye nomphetho ongqindilili xa utyabeka.Kwakhona, ukonyusa ukufana kweglosi yeglosi, zama ukuyila iinxalenye zeplastiki ezinommandla omkhulu wokucwenga ukuze zibe nomfanekiso weparaboli kancinane.

D).Nciphisa ikhefu kunye nokuvela kwiindawo zeplastiki, njengoko iindawo ezinzulu zihlala zityhila iplastiki xa i-plating kunye neprotrusions ithanda ukutshisa.Ubunzulu be-groove akufanele budlule i-1/3 yobubanzi be-groove, kwaye i-bottom kufuneka ijikelezwe.Xa kukho i-grille, ububanzi bomngxuma kufuneka bulingane nobubanzi bombhobho kwaye bungaphantsi kwe-1/2 yobunzima.

E).Izikhundla zokuxhoma ezaneleyo kufuneka zenziwe kwindawo edibeneyo kwaye indawo yokudibanisa kunye nesixhobo sokuxhoma kufuneka ibe ngamaxesha angama-2 ukuya kuma-3 amakhulu kunenxalenye yentsimbi.

F).Amalungu eplastiki kufuneka afakwe kwi-mold kwaye adilizwe emva kokutyalwa, ngoko ke ukuyila kufuneka kuqinisekiswe ukuba iinxalenye zeplastiki zilula ukudilizwa ukuze kungabikho ukuxhaphaza ubuso bamacandelo acwecwe okanye kuchaphazele ukudityaniswa kwe-plating ngokuyinyanzela ngexesha lokuchithwa. .

G).Xa i-knurling ifuneka, i-knurling direction kufuneka ifane ne-demoulding direction kunye nomgca othe ngqo.Umgama phakathi kwemivimbo eneknurled kunye nemigca kufuneka ube mkhulu kangangoko.

H).Kwiindawo zeplastiki ezifuna inlays, kunqande ukusebenzisa izithambiso zentsimbi kangangoko kunokwenzeka ngenxa yendalo engcolisayo yonyango phambi kokwalekwa.

Mna).Ukuba umphezulu wenxalenye yeplastiki igudileyo kakhulu, ayihambelani nokwakheka komgangatho wokutya, ngoko ke umphezulu wenxalenye yesibini yeplastiki kufuneka ube noburhabaxa obuthile.

3.Uyilo lokungunda kunye nokuveliswa

A).Izinto zokubumba akufanele zenziwe nge-beryllium bronze alloy, kodwa umgangatho ophezulu we-vacuum cast steel.Umphezulu womqolo kufuneka ukhazimliswe ukuze ubonakale ukuqaqamba ecaleni kwecala lokungunda, kunye nokungalingani okungaphantsi kwe-0.21μm, kwaye umphezulu kufuneka uqatywe nge-chrome eqinile.

B).Umphezulu wenxalenye yeplastiki ubonisa umphezulu womgodi wokungunda, ngoko ke umngxuma wokungunda wenxalenye yeplastiki ene-electroplated kufuneka ucoceke kakhulu, kwaye uburhabaxa bomphezulu bendawo yokungunda kufuneka bube ngamabakala ali-12 ngaphezulu kunoburhabaxa bomphezulu bomphezulu womhlaba. inxalenye.

C).Umphezulu wokwahlula, umgca wokudityaniswa kunye nomgca we-inlay ongundoqo akufanele uyilwe kwindawo ecwecwe.

D).Isango kufuneka liyilwe kwindawo engqindilili yenxalenye.Ukuthintela ukunyibilika ekupholiseni ngokukhawuleza xa ugcwalisa i-cavity, isango kufuneka libe likhulu kangangoko kunokwenzeka (malunga ne-10% enkulu kunobumba oluqhelekileyo lwesitofu), ngokukhethekileyo kunye necandelo elijikelezileyo lesango kunye ne-sprue, kunye nobude bombhobho. i-sprue kufuneka ibe mfutshane.

E).Imingxuma yokukhupha kufuneka inikezelwe ukuphepha iziphene ezifana neefilaments zomoya kunye namaqamza phezu kwendawo.

F).Indlela yokukhupha i-ejector kufuneka ikhethwe ngendlela yokuqinisekisa ukukhululwa kakuhle kwenxalenye ekubumbeni.

4.Imeko yenkqubo yokubumba inaliti yamalungu eplastiki

Ngenxa yeempawu zenkqubo yokubumba i-injection, uxinzelelo lwangaphakathi alunakuphepheka, kodwa ulawulo olufanelekileyo lweemeko zenkqubo luya kunciphisa uxinzelelo lwangaphakathi lube ncinci kwaye luqinisekise ukusetyenziswa okuqhelekileyo kwamacandelo.

Ezi zinto zilandelayo zichaphazela uxinzelelo lwangaphakathi lweemeko zenkqubo.

A).Ukomisa izinto ezikrwada

Kwinkqubo yokubumba i-injection, ukuba i-raw material esetyenzisiweyo kwi-plating parting ayomile ngokwaneleyo, umphezulu weendawo uya kuvelisa lula iifilaments zomoya kunye namaqamza, okuya kuba nefuthe ekubonakaleni kwengubo kunye namandla okudibanisa.

B).Ubushushu bomngundo

Ubushushu besikhunta sinefuthe elithe ngqo kumandla okudibanisa kwi-plating layer.Xa ubushushu besikhunta buphezulu, i-resin iya kuhamba kakuhle kwaye uxinzelelo olushiyekileyo lwenxalenye luya kuba luncinci, olunceda ekuphuculeni amandla okuxhamla kwi-plating layer.Ukuba iqondo lokushisa lokubumba liphantsi kakhulu, kulula ukwenza i-interlayers ezimbini, ukwenzela ukuba isinyithi singafakwanga xa sisitya.

C).Ukulungiswa kobushushu

Ukuba iqondo lobushushu bokusebenza liphezulu kakhulu, liya kubangela ukucutheka okungalinganiyo, oko konyusa uxinzelelo lweqondo lobushushu, kwaye uxinzelelo lokutywina nalo luya kunyuka, lufuna ixesha lokupholisa elongeziweyo lokudilizwa okugudileyo.Ke ngoko, ubushushu bokulungisa akufunekanga bube buphantsi okanye buphakame kakhulu.Ubushushu bombhobho kufuneka bube ngaphantsi kweqondo eliphezulu lobushushu bomphanda ukuthintela ukuba iplastiki ingaphumi.Ukuthintela izinto ezibandayo kwi-mold cavity, ukwenzela ukuba ugweme ukuveliswa kweengqungquthela, amatye kunye nezinye iziphene kwaye kubangele ukudibanisa kwe-plating embi.

D).Isantya sokutofa, ixesha kunye noxinzelelo

Ukuba ezi zintathu aziphathwa kakuhle, ziya kubangela ukwanda koxinzelelo olushiyekileyo, ke isantya sokutofa kufuneka sicothe, ixesha lokutofa kufuneka libe lifutshane kangangoko, kwaye uxinzelelo lwenaliti kufuneka lungabi phezulu kakhulu, oluya kunciphisa ngokusebenzayo intsalela. uxinzelelo.

E).Ixesha lokupholisa

Ixesha lokupholisa kufuneka lilawulwe ukwenzela ukuba uxinzelelo olushiyekileyo kwi-mold cavity luncitshiswe kwinqanaba eliphantsi kakhulu okanye lisondele kwi-zero ngaphambi kokuba kuvulwe isikhunta.Ukuba ixesha lokupholisa lifutshane kakhulu, ukudilizwa ngenkani kuya kubangela uxinzelelo olukhulu lwangaphakathi kwinxalenye.Nangona kunjalo, ixesha lokupholisa akufuneki libe lide kakhulu, kungenjalo kungekuphela nje ukuba ukusebenza kwemveliso kuya kuba sezantsi, kodwa kunye nokucutha okupholisayo kuya kubangela uxinzelelo phakathi kwemigangatho yangaphakathi nangaphandle yecandelo.Zombini ezi zinto zigqithileyo ziya kunciphisa ukudityaniswa kweplating kwinxalenye yeplastiki.

F).Impembelelo yeearhente zokukhulula

Kungcono ukuba ungasebenzisi ii-agent zokukhulula kwiindawo zeplastiki ezicwecwe.I-oil-based release release agents ayivumelekanga, njengoko inokubangela utshintsho lweekhemikhali kwi-surface layer yenxalenye yeplastiki kwaye iguqule iimpawu zayo zeekhemikhali, okubangela ukungahambi kakuhle kwe-plating.

Kwiimeko apho i-arhente yokukhulula kufuneka isetyenziswe, kuphela i-talcum powder okanye amanzi anesepha kufuneka asetyenziswe ukukhulula ukubumba.

Ngenxa yezinto ezahlukeneyo ezichaphazelayo kwinkqubo yokucoca, iinxalenye zeplastiki ziphantsi kweedigri ezahlukeneyo zoxinzelelo lwangaphakathi, olukhokelela ekunciphiseni ukudibanisa kwe-plating kwaye kufuna unyango olusebenzayo emva kokunyusa ukudibanisa kwe-plating.

Okwangoku, ukusetyenziswa kwonyango lokushisa kunye nonyango kunye nee-agent zokugqiba umphezulu kunempembelelo enhle kakhulu ekupheliseni uxinzelelo lwangaphakathi kwiindawo zeplastiki.

Ukongezelela, iinxalenye ezidibeneyo kufuneka zifakwe kwaye zihlolwe ngokunyamekela ngokugqithiseleyo, kwaye ukupakishwa okukhethekileyo kufuneka kuqhutywe ukuze kugwenywe ukulimaza ukubonakala kweengxenye ezicwengiweyo.
