Izibonda zeUmbhobho we-PEUkufakwa ngokuqhelekileyo ngenxa yokungonelanga kwamandla kwimveliso, ukuzaliswa kwezinto eziphathekayo, kunye noyilo olungekho ngqiqweni lwemveliso. Izibonda zihlala zivela kwindawo engqindilili efana nodonga olubhityileyo. Imingxuma yomoya ibangelwa yiplastiki engonelanga kumgodi wokungunda, iplastiki yeringi yangaphandle iyaphola kwaye yomelele, kwaye iplastiki yangaphakathi iyashwabana ukuze yenze ivacuum. Uninzi lwalo lubangelwa ukuba izinto ze-hygroscopic zingasomisi kakuhle, kunye ne-monomers eseleyo kunye nezinye izinto ezixutywe kwizinto.
Ukugweba isizathu se-pores, kuyimfuneko kuphela ukujonga ukuba iibhubhu ze-PE fittings fittings zivela ngokukhawuleza xa isikhunta sivuliwe okanye emva kokupholisa. Ukuba kwenzeka ngokukhawuleza xa i-mold ivuliwe, ininzi ingxaki yezinto eziphathekayo, ukuba iyenzeka emva kokupholisa, yingxaki yokubumba okanye i-injection molding conditions.

(1) Ingxaki yezinto eziphathekayo:

① Imathiriyeli eyomileyo ②Yongeza isithambiso ③Nciphisa izinto eziguquguqukayo kwimathiriyeli

(2) Iimeko zokubumba i-injection

①Umthamo wenaliti onganelanga; ②Yandisa uxinzelelo lwenaliti; ③Yandisa ixesha lokutofa; ④Yandisa ixesha elipheleleyo loxinzelelo; ⑤Yandisa isantya sokutofa; ⑥Yandisa umjikelo wokutofa; ⑦ Umjikelo wokutofa awuqhelekanga ngenxa yezizathu zokusebenza.

(3) Ingxaki yobushushu

① Izinto ezishushu kakhulu zibangela ukushwabana okugqithisileyo; ② Izinto ezibanda kakhulu zibangela ukuzaliswa okunganeleyo kunye nokuxinana; ③Ubushushu obuphezulu bokungunda bubangela ukuba izinto eziseludongeni lokungunda zingaqini ngokukhawuleza; ④Ubushushu obuphantsi kakhulu bokungunda bubangela ukungagcwali komngundo; ⑤Umngundo uneendawo ezishushu zengingqi ⑥Tshintsha isicwangciso sokupholisa.

(4) Ingxaki yokungunda;

①Yandisa isango; ②Yandisa imbaleki; ③Yandisa umjelo oyintloko; ④Yandisa umngxuma womlomo; ⑤Phucula umbhobho; ⑥Linganisa izinga lokuzaliswa kokungunda; ⑦ Gwema ukuphazamisa ukuhamba kokuzaliswa kwe-mold; ⑧Ulungiselelo lokutya kwesango kwindawo eshinyeneyo yemveliso; ⑨ Ukuba kuyenzeka, nciphisa umahluko kubukhulu bodonga lwezifakelo zemibhobho ye-PE; ⑩Umjikelo wokutofa obangelwa kukungunda awuqhelekanga.

(5) Iingxaki zezixhobo:

①Ukwandisa umthamo weplastiki womatshini wokutofa; ②Yenza umjikelo wenaliti uqheleke;

(6) Ingxaki yemeko yokupholisa:

① IUkufakwa kombhobho we-PEzipholile ixesha elide kwi-mold ukuphepha ukuncipha ukusuka ngaphandle ukuya ngaphakathi kunye nokunciphisa ixesha lokupholisa lokubumba; ②Izifakelo zemibhobho ye-PE zipholile emanzini ashushu.
