Ngenxa yokuhanjiswa okuphezulu kweplastiki ebonakalayo, kukho iimfuno ezingqongqo kumphezulu womgangatho weemveliso zeplastiki, ezinje ngokuba akukho mabala, akukho iipateni, i-porosity, imigca emhlophe, ephethe imigca, amabala amnyama, ukuguquka kombala, ukubengezela okungalinganiyo, njl. ngokupheleleyoisitofu sokubumbainkqubo, kufuneka kubekho iimfuno ezingqongqo nezikhethekileyo zemathiriyeli ekrwada, izixhobo, imibumbo kunye noyilo lwemveliso.
Ekubeni iiplastiki ezicacileyo ngokubanzi zinendawo ephezulu yokunyibilika kodwa ukungahambi kakuhle kwamandla, ukulungelelanisa i-coefficient yeqondo lokushisa lomatshini, uxinzelelo lwe-injection, kunye nesantya se-injection ukuqinisekisa umgangatho womphezulu unokuzalisa indawo yokutofa ngelixa unciphisa amathuba okuvelisa uxinzelelo lwangaphakathi kunye nokubangela ukuguqulwa kunye nokuqhekeka.Ke ngoko, imisebenzi engqongqo kufuneka yenziwe ekulungiseleleni izinto ezikrwada, izixhobo ezinje ngeekhithi zokubumba zeplastiki ezicacileyo kunye neemfuno zokubumba umngundo, inkqubo yokubumba inaliti kunye nokuphathwa kwemveliso ekrwada.Indlela yokwenza iplastiki ecacileyo ngokucacileyo?Ilandelayo yimiba ethile ekufuneka uyazi:
1. Ukulungisa kunye nokomisa izinto ezikrwada
Ekubeni ukungcola okuncinci kwiplastiki kuya kuchaphazela ukungafihli kwemveliso, imveliso kufuneka ivalwe ngokufanelekileyo ngexesha lokugcinwa, ukuthutha kunye nokutya ukuze kuqinisekiswe ukuba umkhiqizo ucocekile, ngokukodwa izinto eziluhlaza zilula ukuwohloka emva kokufudumeza.Kukho ukufuma okuncinci, ngoko kufuneka yomiswe elangeni.Ukongeza, i-hopper kufuneka yomiswe xa isondla.Kwakhona, umoya ongenayo kufuneka ucocwe kwaye uhlanjululwe ngexesha lokumisa ukuze uqiniseke ukuba awungcolisi izinto eziluhlaza.
2.Ukucoca umgqomo, isikrufu kunye nezinye izixhobo
Ukuthintela ukungcoliseka kwezinto ekrwada kunye neentsalela ezifihliweyo okanye ukungcola kwi recesses izincedisi, ingakumbi resin kunye nozinzo amahlwempu thermal, iplastiki kwi ngundo kunye Screw umatshini kufuneka zicocwe kunye neearhente zokucoca ukususa ngokupheleleyo ukungcola, okanye kwi. ukungabikho kwe-screw agents zokucoca, sebenzisa i-PE, i-PS kunye nezinye ii-resin ukucoca i-screw.Xa kuvalwe ngequbuliso, ukuze kuthintelwe ukubola kwezinto ezikrwada kumaqondo obushushu aphakamileyo ixesha elide, ubushushu besomisi kunye nomphanda kufuneka buncitshiswe, njengePC, iqondo lobushushu le-PMMA kufuneka libe ngaphantsi kwe-160 degrees. zicuthwe zibe ngaphantsi kwe-100 degrees PC).
3.Uyilo lokungunda lokutofa kufuneka lunikele ingqalelo kumanqaku alandelayo (kubandakanywa noyilo lwemveliso)
La manqaku alandelayo kufuneka aqatshelwe xa kuyilwa ukubumba ukutofwa kwenaliti ukuthintela ukubunjwa kweplastiki okulambathayo, iziphene zomphezulu kunye nokonakala okubangelwa kukungaqhubi kakuhle kwakhona okanye ukupholisa okungalinganiyo.
a) Ubungqingqwa bodonga kufuneka buqine kangangoko kwaye ithambeka ledrafti yedrafti kufuneka ibenkulu kangangoko.
b) Ukutshintshwa kufuneka kube mnene kwaye kube lula ukukhusela iikona ezibukhali kunye neentambo ezibukhali, ngokukodwa kwiimveliso ze-pc, kwaye akufanele kubekho izikhewu.
c) Isango lokungena: Imbaleki ifanele ibe banzi kwaye ibe mfutshane kangangoko, kwaye indawo yesango kufuneka ihambelane nenkqubo yokushwabana.Izinto ezibandayo ziyafuneka ukuba kuyimfuneko.
d) Indawo yokungunda yesitofu kufuneka igudiswe ibe noburhabaxa obuphantsi (ubukhulu beRa0.8)
e)Inani lemingxuma yokukhupha umoya kunye neendawo zokukhupha umoya kufuneka zanele ukukhupha umoya nerhasi ekunyibilikeni.
f) Ubukhulu bodonga akufunekanga bube mncinci kakhulu ngaphandle kwemathiriyeli ye-PET, ngokubanzi bungabi ngaphantsi kwe-1mm.
Thetha nathi malunga neprojekthi yakho entsha, ukubonisana simahla kunye ne-DFM yasimahla
