Kubumba ninzila yakupanga misyobo isiyene-siyene yama polymers (ma powder, pellets, solutions naa dispersions) kuti zibe zintu zili muchimo nchoyanda. Nchintu chipati kwiinda zyoonse munzila yakubumba zintu zyapulasitiki mpawo ninzila yakupanga zintu zyoonse zya polymer naakuti ma profile. Nzila iiyandika. Nzila zyakubumba zyapulasitiki zibikkilizya kubumba kwiinda mukubelesya nzila ya extrusion, kubumba kwiinda mukubelesya injection, kubumba kwiinda mukusinikizya, kubumba kwiinda mukubelesya nzila yakutola, kubumba kwiinda mukubelesya laminate, kubumba kwiinda mukubelesya blow, kubumba kwa calender, kubumba kwa foam, thermoforming alimwi anzila zimwi zinji, zyoonse eezyi zilakonzya kucinca-cinca.
Kupanga kupya ninzila yakupanga zintu kubelesya mapepa aa thermoplastic mbuli zintu zitabelesyegwi, eezyo zinga zyaambwa kuti zyakachitika akaambo kakubumbwa kwamapulasitiki. Chakusanguna, pepa lyakakosolwa mubupati bumwi abubambe bumwi lilabikkwa afulemu lyachibumbwa, mpawo lipya kusikila lilaanguzu kapati aakati ka Tg-Tf, pepa lilatandabikwa aawo nolipya, mpawo kusinikizyigwa kuchitwa kuti libe afwaafwi achibumbwa. Busena bwachiimo bulikozyene achiimo, mpawo chipangwa chilakonzya kujanwa nikwakamana kutontola, kugonkwa akukosolwa. Muchiindi cha thermoforming, kusinikizyigwa kubelesegwa kuyeeme akusiyana kwakusinikizyigwa kwakachitwa akugusya akunjizya muya uusinkilidwe kumabazu oonse obile aapepa, asi alubo kwiinda mukubelesya kusinikizyigwa kwaminchina akusinikizyigwa kwamaanzi.
Chiimo cha thermoforming nchakuti nguzu zyakupanga zili munsi, mpawo nzila ya thermoforming iliboobu:
bboodi (pepa) lyachibelesyo → kujata → kupya → kusinikizya → kutontozya → kubumba → zintu zitanamana → kutontozya → kugela. Ikupya kwachintu chamanizyigwa kuliindene anzila yakuchita chiindi chomwe mbuli kubumba akugwisya. Tachili cha pulasitiki naakuti ma pellets aakupyisya kubumba naakuti kubumba kuzumanana kakuli chibeela chomwe kwiinda mu dayi; alimwi tachibelesyi zibelesyo zyaminchina, zibelesyo anzila zimwi zyakubelesya minchina kutebula cibeela chapulasitiki. Chitobela, kuti tujane chiimo asayizi ziyandika, pesi kupulasitiki bboodi (pepa) lyachintu, kupya, kubelesya bulongo, vacuum naakuti kusinikizya kuchincha bboodi (pepa) lyachintu. Sika muchimo abwaanda buyandika, antoomwe anzila zigwasilizya, kuchitila kuti uzuzikizye makanze aakubelesya.
Inzila yakupanga zintu zipya yakapangwa kweendelana anzila yakupanga mapepa aabutale. Nikuba kuti chiindi chakwe chakupangwa tachili chilamfu pe, pesi kuchita chakufwambaana, nzila yakuchita zintu zilikke ilisumpukide, chibumbwa tachiduli pe mpawo nchuubauba kuchincha, mpawo chikonzya kuchincha nchintu chiyumu. Ilakonzya kupanga zintu zipati mbuli ndeke azibeela zyamootokala, ziniini mbuli nkomeki zyakunywa. Zyakulya zyakasyeede nzyuba kuzibelesya lubo. ilakonzya kubamba mapepa aateteete kusika ku 0.10mm mubufwaafwi. Mapepa aaya alakonzya kuba aasalala naakuti aatakwe mumuni, aasalala naakuti aatakwe mumuni. Ma pateni alakonzya kusimbwa apepa kusaanguna, naakuti ma pateni aamibala iimvwika alakonzya kusimbwa nikwakamana kubumbwa.
Muminyaka iili 30 kusikila ku 40 yainda, akaambo kakuvwula kwamisyobo yama thermoplastic sheet (sheet) mbuli zintu zitabelesyegwi, kuzumanana kuyaambele kwaminchina ya thermoforming, akubelesya zintu zyiingi, thermoforming technology yakasumpuka. Kakuli kuyaambele kupati, zibelesyo zyayo zyalondokede. Mukweezyanisya a injection molding, thermoforming ilijisi bubotu bwakupanga zintu obotu, nzila ngubauba, kubelesya zibelesyo zisyoonto, akukonzya kupanga zintu zili abusena bupati. Nokuba boobo, muulo wakubamba zintu zitabelesyegwi kuti kazipya ulisumpukide, alimwi kuli nzila zyiingi zyakumana kubamba zintu. Kakuli kuyaambele kwabusongo bwakupanga zintu akuyandikana kwakuyungizya mpindu, zibelesyo zyakupanga zintu zyakamana asyoonto-asyoonto mbuli nzila yakubumba zintu zyamapulasitiki, mpawo zyakatalika kuswaangana azibelesyo zimwi zyakupanga zintu kutegwa zizuzikizye bupange A complete production line for specific needs, aboobo zyayungizya kusumpula kupanga zintu akucesya muulo wakupanga zintu.
Kupanga kupya nchintu chibotu loko mukupanga zintu zili abwaanda buteteete antoomwe amasena mapati. Misyobo yamapulasitiki iibelesyegwa kapati ibikkilizya polystyrene, plexiglass, polyvinyl chloride, abs, polyethylene, polypropylene, polyamide, polycarbonate antoomwe a polyethylene terephthalate.
