Umgaqo wokuyila wokubumba

Uyilo lweefomati zokwenza i-vacuum zibandakanya ubungakanani be-batch, izixhobo zokubumba, iimeko ezichanekileyo, uyilo lwejometri, uzinzo lobukhulu kunye nomgangatho womphezulu.

1. Ubungakanani beebatch busetyenziselwa iimvavanyo. Xa ukukhutshwa kokubumba kuncinci, kunokwenziwa ngokhuni okanye nge-resin. Nangona kunjalo, ukuba isikhunta sokuvavanya sisetyenziselwa ukufumana idatha kwi-shrinkage, kuzinzo lobukhulu, nakwixesha lomjikelo wemveliso, kufuneka kusetyenziswe isikhunta esinye sentshinyela kulingo kwaye sinokusetyenziswa phantsi kweemeko zemveliso. Imozulu idla ngokwenziwa ngejypsum, ubhedu, ialuminiyam okanye ialuminium zentsimbi, kunye ne-aluminium-resins azifane zisetyenziswe.

I-2, uyilo lwejometri yoyilo, uyilo, amaxesha amaninzi kufuneka luqwalasele uzinzo lomgangatho kunye nomgangatho womphezulu. Umzekelo, uyilo lwemveliso kunye nokuzinza okumiselweyo kufuna ukusetyenziswa kobumba lowasetyhini (isikhunta sowesifazane), kodwa umphezulu ufuna imveliso ephezulu kakhulu, kodwa ifuna ukusetyenziswa kobumba lobudoda (iprotrusion), ukuze amacandelo eplastikhi alele iqela aliqwalasele. Ezi ngongoma zimbini ukwenzela ukuba imveliso iveliswe phantsi kweemeko ezifanelekileyo. Amava abonakalisile ukuba uyilo olungazifezekisiyo iimeko zokwenza izinto zihlala zisilela.

3, ubungakanani buzinzile, kwinkqubo yokubumba, umphezulu wenxalenye yeplasitiki ekunxibelelaneni nomngundo ungcono kunokuma okuqinileyo kwinxalenye eshiya ukubumba. Ukuba ubuninzi bezinto ezibonakalayo kufuneka zitshintshe kwixesha elizayo ngenxa yokuqina kwempahla, oko kungakhokelela ekuguqulweni kobumba lobudoda kubunjani besetyhini. Ukunyamezeleka kokumiselweyo kwenxalenye yeplastiki akunakuba ngaphantsi kwe-10% yereyitha yokushrinkage.

4. Umphezulu wenxalenye yeplastiki. Ngokoluhlu apho izinto zokubumba zinokusongelwa khona, umphezulu womhlaba obonakalayo wenxalenye yeplasitiki kufuneka wenziwe ekunxibelelaneni nobumba. Ukuba kunokwenzeka, icala elicocekileyo leplastikhi akufuneki lidibane nomhlaba wokubumba. Kufana nokusebenzisa isikhunta sowasetyhini ukwenza ityhubhu kunye nebhafu yokuhombisa.

I-5, uguquko, ukuba usebenzisa umatshini otyhidiweyo ojikelezayo ukuze ubone umphetho wecandelo leplastiki, kwicala lokuphakama, ubuncinci yi-6 ~ 8mm yokulinganisa. Omnye umsebenzi wokugqiba, njengokugaya, ukusika i-laser okanye ukuqhutha, kufuneka nawo ashiye umda. Umsantsa phakathi kwemigca yokusika yesitshixo yeyona incinci, kwaye ububanzi bokusasaza xa kufakwe i-punching die nabo bumncinci, ekufuneka kuqatshelwe.

I-6, i-shrinkage kunye ne-deformation, i-shrinkage yeplastiki (efana ne-PE), ezinye iinxalenye zeplasitiki zilula ukuzonakalisa, akunandaba nokuba zithintela, iinxalenye zeplasitiki ziya kuchaphazeleka ngexesha lesigaba sokupholisa. Ngaphantsi kwale meko, ubume befom eguqulwayo butshintshiwe ukulungiselela ukulungiselela ukuphambuka kwejometri yecandelo leplastiki. Umzekelo, nangona udonga lwenxalenye yeplastiki lugcinwe luqondile, embindini wesalathiso siphambukile ngo-10 mm; isiseko sokubumba sinokuphakanyiswa ukuhlengahlengisa ubungakanani be-shrinkage yale ntsingiselo.

7. Isixa se-shrinkage kufuneka sijongwe kwimveliso yokubumba iiplastiki. 1 Imveliso ebunjiweyo iyancipha. Ukuba i-shrinkage yeplastiki ayaziwa ngokucacileyo, kufuneka isampuli okanye ihlolwe ngumbumba obunjwe ngokufanayo. Qaphela: Kuphela yi-shrinkage enokuthi ifunyanwe ngale ndlela, kwaye ubungakanani obonakalisiweyo abunakufunyanwa. 2 I-shrinkage ebangelwa ziziphumo ezibi zaphakathi, ezinje ngeceramics, irabicic irabha, njl.
