Iindaba zeNkampani

I-mold yeplastiki sisixhobo esihambelana noomatshini bokubumba beplastiki kwishishini lokucubungula iplastiki ukunika iimveliso zeplastiki ulungelelwaniso olupheleleyo kunye nobukhulu obuchanekileyo. Ngokweendlela ezahlukeneyo zokubumba, inokwahlulwa ibe ziintlobo ezahlukeneyo ze-mold.

1. I-die yokubumba ye-polystyrene eyandisiweyo kakhulu

Luhlobo lwesikhunta olusebenzisa i-polystyrene enokunwebeka (izinto ezenziwe nge-polystyrene kunye ne-foam agent) izinto ezikrwada ukwenza izinto zokupakisha ze-foam ezineemilo ezahlukeneyo ezifunwayo.

Umgaqo kukuba i-polystyrene enwebekayo ingaphekwa ngomphunga kwi-mold, kuquka iintlobo ezimbini ze-molds ezilula zokusebenza ngesandla kunye ne-hydraulic straight-through foam plastic molds, ezisetyenziswa kakhulu ukuvelisa iimveliso zokupakisha zeemveliso zoshishino. Izixhobo zokwenza ezo molds yi-aluminium ephosiweyo, intsimbi engatyiwayo, ibronze, njl.

2. Isikhunta soxinzelelo

Kubandakanya ukubumba okucinezelweyo kunye nokubumba ngenaliti, kukho iintlobo ezimbini zokubumba ezisetyenziswa kakhulu ekubumbeni iiplastiki ezisebenzisa i-thermosetting, kwaye izixhobo zazo ezihambelanayo ngumatshini wokubumba ocinezelayo.

Indlela yokubumba ngokucinezela Ngokweempawu zeplastiki, isikhunta sifudunyezwa ukuya kubushushu bokubumba (ngokubanzi yi-103°108°), emva koko umgubo wokubumba ngokucinezela olinganisiweyo ufakwa kwindawo yokubumba nakwigumbi lokutyela, isikhunta siyavalwa, kwaye iplastiki ifudunyezwa phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu. Thambisa ukuhamba okuxineneyo, uqine kwaye umile emva kwexesha elithile, kwaye ube yimo yemveliso oyifunayo.

Umahluko phakathi kokubumba ngenaliti kunye nokubumba ngokucinezela kukuba akukho gumbi lokutyisa elahlukileyo. Isikhunta siyavalwa ngaphambi kokubumba, kwaye iplastiki itshiswa kwigumbi lokutyisa kwaye iba yimeko yokuhamba okuxineneyo. Phantsi kwesenzo soxinzelelo, iyalungiswa kwaye icinezelwe kwingxinano yesikhunta ukuze iqine kwaye ibumbeke.

I-compression mold yenziwe ikakhulu nge-cavity, i-feeding cavity, i-guiding mechanism, i-ejecting parts, i-heating system, njl. Ii-injection molds zisetyenziswa kakhulu ekupakisheni izinto zombane. Izinto ezisetyenziswa ekwenzeni ii-compression molds ziyafana nee-injection molds.

3. Isikhunta senaliti

Ngokuyintloko yi-mold yokubumba esetyenziswa kakhulu ekuveliseni iindawo ze-thermoplastic. Izixhobo zokucubungula ezihambelana ne-injection mold ngumatshini wokubumba i-injection. Iplastiki iqala ifudumale ize inyibilike kwi-heating barrel esezantsi komatshini wokubumba i-injection. Phantsi kokutyhalwa yiplagi, ingena kwi-mold cavity nge-injection mold machine nozzle kunye nenkqubo yokuthulula i-mold, kwaye iplastiki iyapholiswa kwaye iqiniswe ukuze yenziwe, kwaye imveliso ifunyanwa ngokuyisusa.

Ulwakhiwo lwayo ludla ngokwakhiwa zizinto zokwenza, inkqubo yokuthulula, iindawo ezikhokelayo, indlela yokutyhala, inkqubo yokulawula ubushushu, inkqubo yokukhupha umoya, iindawo ezixhasayo kunye nezinye iindawo, kwaye yenziwe ngentsimbi yeplastiki yokubumba. Inkqubo yokubumba ngenaliti idla ngokufanelekela kuphela ukuveliswa kweemveliso ze-thermoplastic. Iimveliso zeplastiki eziveliswa yinkqubo yokubumba ngenaliti zibanzi kakhulu. Ukususela kwizinto eziyimfuneko zemihla ngemihla ukuya kwizixhobo ezahlukeneyo zombane ezintsonkothileyo kunye neendawo zeemoto, zonke zenziwe ngezixhobo zokubumba ngenaliti. Enye yezona ndlela zisetyenziswa kakhulu ekuveliseni iimveliso zeplastiki.

4. Ukufutha isikhunta

Isikhunta esisetyenziselwa ukwenza iimveliso ezingenanto zesikhongozeli seplastiki (ezifana neebhotile zesiselo, iimveliso zeekhemikhali zemihla ngemihla kunye nezinye izikhongozeli zokupakisha). Uhlobo lwesikhunta se-blow lubandakanya ikakhulu isikhunta se-extrusion blow kunye ne-injection molding ngokwemigaqo yenkqubo. Lo mgaqo ubandakanya ikakhulu isikhunta se-extrusion blow, i-injection blow molding, i-injection extension blow molding (eyaziwa ngokuba yi-injection stretch blow), i-multi-layer blow molding, i-sheet blow molding, njl. Izixhobo ezihambelana nesikhunta se-blow seemveliso ezingenanto zihlala zibizwa ngokuba ngumatshini we-plastic blow molding, kwaye isikhunta se-blow molding sifanele kuphela ukuveliswa kweemveliso ze-thermoplastic. Ulwakhiwo lwesikhunta se-blow lulula, kwaye izixhobo ezisetyenziswayo zenziwe kakhulu nge-carbon.

5. Idayi yokukhupha

Uhlobo lwesikhunta esisetyenziselwa ukuvelisa iimveliso zeplastiki ezimile ngokuqhubekayo, okwaziwa ngokuba yi-extrusion molding head, lusetyenziswa kakhulu ekucutshungulweni kwemibhobho, iibhari, ii-monofilaments, iipleyiti, iifilimu, i-wire kunye ne-cable cladding, izinto ezifakwe iprofayili, njl.njl.

Izixhobo zemveliso ezifanelekileyo yiplastiki extruder. Umgaqo kukuba iplastiki eqinileyo iyanyibilika kwaye yenziwe iplastiki phantsi kweemeko zokufudumeza kunye nokujikeleza kwezikrufu kwe-extruder, kwaye yenziwe ibe yindawo efanayo neyomfanekiso wedayi ngedayi yesimo esithile. Iimveliso zeplastiki eziqhubekayo. Izinto zayo zokwenza imveliso ikakhulu yintsimbi yesakhiwo sekhabhoni, izixhobo ze-alloy, njl.njl., kwaye ezinye iidayi ze-extrusion nazo zigqunywe ngezinto ezingagugiyo ezifana nedayimani kwiindawo ekufuneka zingagugiyo.

Inkqubo yokukhupha idla ngokufaneleka kuphela kwimveliso yeemveliso ze-thermoplastic, ezahluke kakhulu kwii-injection molds kunye ne-compression molds kwisakhiwo.

6. Isikhunta se-blister

Isikhunta esisebenzisa iipleyiti zeplastiki kunye namaphepha njengezinto zokwenza iimveliso zeplastiki ezilula. Kwimeko yokuthambisa, siyaguquguquka size sinamathele emngxunyeni wesikhunta ukuze kufunyanwe imveliso efunxwayo, esetyenziswa kakhulu ekuveliseni izinto eziyimfuneko zemihla ngemihla, ukutya kunye neemveliso zokupakisha amathoyizi.
