Gawo loyamba: Unikani ndi kusinkhasinkha zojambula za 2D ndi 3D za chinthucho, ndikukhazikitsa kapangidwe kakePVC chitoliro choyenera nkhunguZomwe zili mkati mwake zikuphatikizapo zinthu izi:
1. Mawonekedwe a chinthucho. (Chitoliro cha PVC chopangidwa ndi chitsulo, swrchitoliro chopangidwa ndi chitoliro)
2. Miyeso ya zinthu, kulekerera ndi miyeso ya kapangidwe.
3. Zofunikira zaukadaulo za chinthucho (monga kuuma, kuchuluka kwa pulasitiki, ndi zina zotero, nthawi zina kubwezeretsanso kwa chinthucho kuyenera kuganiziridwa)
4. Dzina, kuchepa ndi mtundu wa pulasitiki yomwe yagwiritsidwa ntchito mu chinthucho. (Mwachitsanzo,PVC chitoliro choyenera nkhungundiUPVC, chitoliro cholumikizira chitoliro cha CPVCgwiritsani ntchito zipangizo zosiyanasiyana za nkhungu popanga)
5. Zofunikira pa malo a chinthucho.
Gawo 2: Dziwani chitsanzo cha makina ojambulira.
Mafotokozedwe a makina ojambulira amadalira makamaka kukula kwa chinthu cha pulasitiki ndi gulu lopangira. Posankha makina ojambulira, wopanga amaganizira kwambiri kuchuluka kwa pulasitiki, kuchuluka kwa jakisoni, mphamvu yolumikizira, malo ogwira ntchito a nkhungu yoyika (mtunda pakati pa ndodo zomangira makina ojambulira), modulus, mawonekedwe otuluka ndi kutalika kwa kutuluka.
Ngati kasitomala wapereka chitsanzo kapena zofunikira za makina ojambulira omwe agwiritsidwa ntchito, wopanga ayenera kuyang'ana magawo ake. Mwachitsanzo, ngati kasitomala asankha mtunda wamkati wa ndodo zomangira za makina ojambulira jakisoni kukhala 680 * 680mm, kukula kwaPVC chitoliro choyenera nkhunguSayenera kupitirira malire awa, apo ayi cholowacho chiyenera kukambidwa ndi kasitomala.
Gawo lachitatu: kudziwa kuchuluka kwa mabowo aPVC chitoliro choyenera nkhungundi kapangidwe ka mabowo Kudziwa kuchuluka kwa mabowo a nkhungu kumadalira makamaka malo omwe chitolirocho chapangidwa, mawonekedwe ake (ndi kapena popanda kukoka mbali), kulondola kwa chinthucho, kukula kwa gulu ndi phindu lazachuma. Chiwerengero cha mabowo chimatsimikiziridwa makamaka kutengera zinthu zotsatirazi:
1. Gulu la zinthu zopangidwa (gulu la pamwezi kapena gulu la pachaka).
2. Ngati mankhwalawo ali ndi mbali yolumikizira pakati ndi njira yake yochizira.
3. Miyeso yakunja ya nkhungu ndi malo ogwira ntchito a nkhungu yomwe yaikidwa pa makina ojambulira (kapena mtunda pakati pa ndodo zokokera za makina ojambulira).
4. Kulemera kwa chinthu ndi kuchuluka kwa jakisoni wa makina ojambulira.
5. Malo oyeretsedwa ndi mphamvu yogwirira ntchito ya chinthucho.
6. Kulondola kwa zinthu.
7. Mtundu wa chinthu.
8. Ubwino wa zachuma (mtengo wopangira nkhungu iliyonse).
Pambuyo poti chiwerengero cha mabowo chadziwika, dongosolo la mabowo ndi kapangidwe ka malo a mabowowo zimachitika. Dongosolo la mabowowo limaphatikizapo kukula kwa nkhungu, kapangidwe ka dongosolo la gating, kulinganiza kwa dongosolo la gating, kapangidwe ka makina okoka pakati (core putting), kapangidwe ka insert core ndi kapangidwe ka dongosolo la hot runner. Mavuto omwe ali pamwambawa akukhudzana ndi kusankha malo olekanitsira ndi malo a chipata, kotero mu njira yeniyeni yopangira, kusintha kofunikira kuPVC chitoliro choyenera nkhunguamafunika kuti apange kapangidwe kabwino kwambiri.
Kudzera mu masitepe atatu omwe ali pamwambapa, mtengo wa chitoliro cholumikizira chitoliro cha PVC, dongosolo loyenera lopangira, ndi phindu lachuma la nthawi yayitali zitha kuwerengedwa mozama. Kuti musankhe opanga chitoliro ndi kukonzekera kupanga pambuyo pake, kukonzekera bwino komanso kusintha kwa nthawi yake kungapangidwe. Longxin Mold imayang'ana kwambiri pakupanga ndi kupangaZipangidwe za chitoliro cha PVCNgati mukufuna wogulitsa wodalirika wa zinyalala za mapaipi, chonde titumizireni nthawi yomweyo. Gulu la akatswiri ogulitsa la Longxin Mold lidzakulumikizani mwachangu momwe zingathere.
