Iimbobo zeUmbhobho we-PEIzifakelo zihlala zibangelwa kukungabikho kwamandla aneleyo kwimveliso, ukuzaliswa kwezinto ngokwaneleyo, kunye noyilo lwemveliso olungafanelekanga. Izimbobo zihlala zibonakala kwindawo enodonga oluqinileyo efana nodonga olubhityileyo. Imingxunya yomoya ibangelwa kukungabikho kweplastiki ngokwaneleyo kwindawo yokubumba, iplastiki yesangqa sangaphandle iyaphola kwaye iqina, kwaye iplastiki yangaphakathi iyancipha ukuze yenze i-vacuum. Uninzi lwayo lubangelwa zizinto ezi-hygroscopic ezingomiswanga kakuhle, kunye nee-monomers eziseleyo kunye nezinye izinto ezikwizinto.
Ukuze kugwetywe unobangela weembobo, kufuneka kujongwe kuphela ukuba amaqamza ee-PE pipe fittings avela ngoko nangoko xa i-mold ivulwa okanye emva kokuba ipholile. Ukuba iyenzeka ngoko nangoko xa i-mold ivulwa, ikakhulu yingxaki yezinto eziphathekayo, ukuba iyenzeka emva kokuba ipholile, yingxaki nge-mold okanye i-injection molding.

(1) Ingxaki yezinto eziphathekayo:

①Izinto ezomileyo ②Yongeza i-lubricant ③Nciphisa izinto eziguquguqukayo kwizinto ezomileyo

(2) Iimeko zokubumba ngenaliti

①Umthamo wokujova awanelanga; ②Nyusa uxinzelelo lokujova; ③Nyusa ixesha lokujova; ④Nyusa ixesha loxinzelelo lilonke; ⑤Nyusa isantya sokujova; ⑥Nyusa umjikelo wokujova; ⑦Umjikelo wokujova awuqhelekanga ngenxa yezizathu zokusebenza.

(3) Ingxaki yobushushu

①Izinto ezishushu kakhulu zibangela ukushwabana okukhulu; ②Izinto ezibandayo kakhulu zibangela ukugcwala okunganelanga kunye nokuxinana; ③Ubushushu obuphezulu kakhulu bokubumba bubangela ukuba izinto ezikudonga lobumba zingaqini ngokukhawuleza; ④Ubushushu obuphantsi kakhulu bokubumba bubangela ukugcwala okunganelanga kokubumba; ⑤Izinto ezishushu kakhulu zifumaneka kwindawo ethile ⑥Tshintsha isicwangciso sokupholisa.

(4) Ingxaki yokungunda;

①Yandisa isango; ②Yandisa umdyarho; ③Yandisa umjelo oyintloko; ④Yandisa umngxuma womlomo; ⑤Phucula ukukhupha umoya kwisikhunta; ⑥Linganisa izinga lokuzalisa isikhunta; ⑦Kuphephe ukuphazamiseka kokuhamba kokuzalisa isikhunta; ⑧Ulungiselelo lwesango kwindawo enodonga oluqinileyo lwemveliso; ⑨Ukuba kunokwenzeka, nciphisa umahluko kubukhulu bodonga lwezixhobo zombhobho ze-PE; ⑩Umjikelo wokujova obangelwa yisikhunta awuqhelekanga.

(5) Iingxaki zezixhobo:

①Nyusa amandla okwenza iplastiki kwi-injection press; ②Yenza umjikelo we-injection ube yinto eqhelekileyo;

(6) Ingxaki yemeko yokupholisa:

①IIzixhobo zepayipi ze-PEZipholiswa ixesha elide kakhulu kwisikhunta ukuze zinganciphi ukusuka ngaphandle ukuya ngaphakathi kwaye zinciphise ixesha lokuphola kwesikhunta; ②Izixhobo zepayipi ze-PE zipholiswa ngamanzi ashushu.
