Mu mzere wopanga mapaipi apulasitiki, ukadaulo wosadziwa bwino ntchito wa wogwiritsa ntchito komanso kugwiritsa ntchito makinawo kudzapangitsa kuti chitoliro cha pulasitiki chiwoneke cholimba pamwamba pakunja, mphete yogwedezeka mkati, makulidwe osafanana a khoma, kuzunguliridwa kosakwanira ndi zina zotero. Chifukwa chake, kusintha kwa nthawi yake njira zopangira mapaipi apulasitiki ndi kuthetsa mavuto pa mzere wopanga mapaipi apulasitiki kungathandize kuti zinthu zikhale bwino.

1.Kunja kwa chitoliro cha pulasitiki ndizovuta
● Sinthani kutentha kwa ndondomeko;
● Chepetsani kutentha kwa madzi ozizira, kutentha kwabwino kwa madzi ozizira a mapaipi a PE ndi 20～25℃;
● Yang'anani njira yamadzi kuti muwone ngati pali kutsekeka kapena kuthamanga kwa madzi kosakwanira;
● Yang'anani ngati mphete yotenthetsera ya mbiya, mutu, ndi zina zotero yawonongeka;
● Sinthani kayendedwe ka madzi olowera mu chikwama cha kukula;
● Yang'anani makhalidwe ndi ziwerengero za zinthu zopangira;
● Onani kutentha kwapakati pa nkhungu. Ngati ndipamwamba kuposa kutentha kwa gawo la kufa, tsitsani kutentha kwa mtima;
● Tsukani zinthu zonse za nkhungu;

2. Grooves amawonekera kunja kwa chitoliro cha pulasitiki
● Sinthani mphamvu ya madzi yotulutsira m'chikwama cha kukula, ndipo madzi otuluka amafunika kuti akhale oyenera;
● Sinthani ngodya ya nozzle mu bokosi lopangira vacuum kuti chitoliro chizizire mofanana;
● Yang'anani pansi, kusanja malaya, makina odulira, ndi zida zina za zinyalala, zokwirira, ndi zina zotero;

3. Mizere imawonekera pamwamba pa mkati
● Yang'anani ngati madzi alowa mu chubu chamkati. Ngati madzi alowa, tsinani chubu cha nkhungu mutangotuluka kuti mutseke mkati mwake;
● Kuchepetsa kutentha kwa mkati mwa nkhungu;
● Tsukani ndi kupukuta nkhungu;

4. Mphete ya jitter imawonekera mkati mwa chitolirocho
● Sinthani malo otulutsira madzi a chikwama cha kukula kuti chikhale chofanana;
● Sinthani mlingo wa vacuum wa chipinda chachiwiri kuti mlingo wa vacuum wa chipinda chakumbuyo ukhale wokwera pang'ono kuposa mlingo wa vacuum wa chipinda chakutsogolo;
● Yang'anani ngati chisindikizo cha vacuum ndicholimba kwambiri;
● Onani ngati thirakitala ikugwedezeka;
● Onetsetsani ngati makina akuluakulu akutulutsa madzi mofanana;

5. Palibe vacuum
● Onani ngati cholowera madzi cha pampu yotsekera chatsekedwa. Ngati chatsekedwa, tsegulani;
● Onani ngati pampu ya vacuum ikugwira ntchito nthawi zambiri;
● Onani ngati payipi ya vacuum ikutuluka;
● Onani ngati bowo laling'ono lomwe lili pakati pa tsinde la pulasitiki latsekeka. Ngati chatsekeka, gwiritsani ntchito waya wopyapyala wachitsulo kuti muchotse;

6. Mbali yakunja ya chitoliro ndiyosalolera
● Kukula kwa bwalo lakunja kungasinthe mwa kusintha digiri ya vacuum;
● Kukula kwa mphete yakunja kungasinthe mwa kusintha liwiro la kukoka;
● Konzani kukula kwa dzenje lamkati la manja opangira;

7. Kuzungulira kwa chitoliro ndi chifukwa cha kulolerana
● Sinthani ngodya ya nozzle mu makina okonzera vacuum ndi bokosi lopopera kuti chitoliro chiziziritse mofanana;
● Yang'anani zida zopangira vacuum, kuchuluka kwa madzi mu bokosi lopopera, komanso kuthamanga kwa geji yoyezera kuthamanga kwa madzi kuti voliyumu yopoperayo ikhale yayikulu komanso yamphamvu;
● Yang'anani kutentha kwa madzi a makina opangira vacuum ndi bokosi lopopera. Ngati ndi> 35 ℃, madzi ozizira kapena bokosi lopopera lopopera liyenera kuwonjezera;
● Yang'anani njira yamadzi ndikutsuka fyuluta;
● Sinthani njira;
● Yang'anani ndikuwongolera kuzungulira kwa dzenje lamkati la manja oyesa;
● Sinthani chiwongolero cha chitoliro ndi chipangizo cholumikizira kuti chiwongolere chitoliro;

8. Kukhuthala kwa khoma la chitoliro chosafanana
● Sinthani makulidwe a khoma pa chikombole;
● Sinthani ngodya ya nozzle mu makina oyika vacuum ndi bokosi lopopera kuti chitolirocho chizizizira bwino; sinthani kutulutsa kwamadzi pamanja kuti mufanane;
● Sonkhanitsani chikombole, yang'anani ngati zomangira mkati mwa chikombolezo zili zomasuka, ndipo chitsekeninso;

9. Kutentha kwa plasticizing ndikokwera kwambiri
● Sinthani ndondomeko;
● Sinthani kutentha kwa kutentha kwa pakati pa nkhungu ndikupumitsa ndi kuziziritsa nkhungu;
● Kutentha kwakukulu kwa screw ndi kwakukulu kwambiri, sinthani screw;

10. Kutalika kolakwika kwa kudula
● Onani ngati gudumu lalitali lakanikiza mwamphamvu;
● Yang'anani ngati gudumu lalitali likugwedezeka, ndipo limbitsani mabotolo omangira chimango cha gudumu lalitali;
● Yang'anani ngati chosinthira cha makina odulira chawonongeka;
● Yang'anani ngati encoder yozungulira yawonongeka;
● Kaya mawaya a makina osindikizira atsekedwa (ngati mpando wa pulagi ya ndegeyo uli bwino);

Malo aliwonse okhazikika okha (PE terminal) ayenera kukhazikitsidwa padera pamalo onse okhazikika kuti pakhale maziko odalirika. Malo okhazikika ayenera kukhala ndi malo okhazikika omwe akukwaniritsa zofunikira zamagetsi. Sikololedwa kulumikiza malo okhazikika okha (PE terminals) motsatizana ndi pansi. Kupanda kutero, adzayambitsa kusokoneza kwa kugunda kwa mtima, zomwe zimapangitsa kuti kudula kusakhale kolondola;

11. Vuto la chizindikiro cha co-extrusion
Kuphatikizika kwa zingwe zozindikiritsira ma co-extrusion: Nthawi zambiri, zimayambitsa kusankha kolakwika kwa zida zolumikizirana ndi ogwiritsa ntchito. Zida zapadera, monga PE, ziyenera kugwiritsidwa ntchito. Ngati ndi kotheka, kutentha kwa gawo la extrusion kumatha kuchepetsa;
Chotulutsira mpweya chophatikizana sichingathe kufinya: imitsani chotulutsira mpweya chachikulu, yatsani kaye makina otulutsira mpweya, ndikuyatsa chipangizo chotulutsira mpweya chophatikizana kwa mphindi pafupifupi 10 musanayatse chosungira mpweya;
Mzere wa co-extrusion ndi wochepa thupi kwambiri kapena wotakata kwambiri: Nthawi zambiri, zimayambitsa kusagwirizana pakati pa kuchuluka kwa makina opangira-extrusion ndi kuthamanga kwa chitoliro ndipo ziyenera kusinthidwa, ma frequency converter a injini ya co-extrusion kapena kusintha liwiro la kukokera kuti lifanane ndi mitengo iwiriyi;
Chachiwiri ndi chifukwa chake jekete la madzi ozizira la gawo lotulutsira katundu la co-extruder silidutsa m'madzi ozizira;
Pakupanga kwenikweni kwa mzere wopangira chitoliro, padzakhala zinthu zina zachilendo, zomwe ziyenera kuthana nazo molingana ndi momwe zilili.
