Ukwenza induku enhle enentambo akuwona umsebenzi olula futhi kudinga izimo ezimbalwa:
1. Isikulufu kufanele sibe seduze ukuze kushanele sonke isikulufu sangaphakathi, ukuze sithole ukuqhutshwa kokushisa okuhle, umphumela wokuhlanganisa kanye nesikhathi sokusabalalisa esiwumngcingo.
2. Ukucaciswa kwe-radial phakathi kwesikulufu kanye nomgqomo (umgqomo) kufanele kube ngaphansi kuka-0.003 ubukhulu besikulufu.
3. Idizayini elula yamukelwa ukugwema amakhona afile.
4. Uma ipulasitiki iqukethe izinhlayiya eziqinile zokupakisha ezidinga ukuchotshozwa okukhulu kokucindezeleka, kuyadingeka futhi ukukhetha iyunithi yokuxuba ehlakazekile.Iyunithi yokuxuba ukuhlakazeka iphinde iqinisekise ukuthi izinhlayiya zepulasitiki ezingahlanganisiwe azithuthwa ekupheleni kwesikulufu.Ngakho-ke, amayunithi okuxuba okuhlakazeka awusizo ngisho noma zingekho izinhlayiya eziqinile zokugcwalisa epulasitiki.
5. Ukumiswa kwesigaba sokuxuba kokusabalalisa kufanele kucatshangelwe ngokugcwele ukuze kuncishiswe umehluko wokungaguquguquki kanye nokungafanani kwezinga lokushisa elincibilikayo.Isikhundla esithandwayo sesigaba sokuxuba sisekupheleni kwesikulufu.
6. Uma ipulasitiki enokugqwala okuminyene, njengokugqwala kwe-dioxide, ingilazi nokunye, isikulufu nomgqomo (umgqomo) kufanele wenziwe ngezinto ezingagugi.
7. Uma i-PVC ye-extrusion, ipulasitiki ye-fluorine noma enye ingenza ukugqwala kothuli lwegolide lwepulasitiki obala, isikulufu, umgqomo (umgqomo) kanye nokusetshenziswa kwekhanda lomshini lokukhiqiza izinto ezimelana nokugqwala.
8. Isigaba sokuxuba kufanele sibe nokwehla kwengcindezi ephansi kanye nomthamo omuhle kakhulu wokupompa phambili.
9. Ukuze kuthuthukiswe ukusebenza kokudlulisa kwezinto futhi kuncishiswe izinto ezilengayo, irediyasi ye-fillet engaphansi kwe-thread groove kufanele ibe nkulu, futhi izintambo eziningi kanye ne-pitch encane kufanele igwenywe ukuze kuncishiswe ukungqubuzana kwesikulufu nokuthuthukisa umthamo wokudlulisa. .
10. Uma isikulufu siboshwe, ukugqoka okuhambisana nokungqubuzana okuphansi kufanele kunikezwe kuqala.Lokhu kuthuthukisa ukusebenza kokulethwa kwezikulufu, okuholela ekuvuneni okuphezulu nokuzinza okungcono, futhi isikulufu kulula ukusihlanza.
