Malinga ndi chikhalidwe cha pulasitiki, ndizovuta komanso zolemetsa kuzipanga kukhala zinthu zapulasitiki zokhala ndi mawonekedwe enaake komanso mtengo wogwiritsa ntchito.Popanga mafakitale apulasitiki, njira yopangira zinthu zapulasitiki imapangidwa makamaka ndi njira zinayi zopitilira: kupanga pulasitiki, kukonza makina, kukongoletsa ndi kusonkhana.
Mu njira zinayi izi, pulasitiki akamaumba ndi chinsinsi processing pulasitiki.Njira zopangira mitundu 30, makamaka mitundu yosiyanasiyana ya pulasitiki (ufa, tinthu tating'ono, yankho kapena kubalalitsidwa) munjira yomwe mukufuna ya chinthucho kapena billet.Njira yopangira imadalira makamaka mtundu wa pulasitiki (thermoplastic kapena thermosetting), mawonekedwe oyambirira, ndi mawonekedwe ndi kukula kwa mankhwala.Pulasitiki processing thermoplastics njira ambiri ntchito ndi extrusion, jekeseni akamaumba, calendering, kuwomba akamaumba ndi otentha akamaumba, pulasitiki processing thermosetting mapulasitiki ambiri ntchito akamaumba, kusamutsa akamaumba, komanso jekeseni akamaumba.Laminating, kuumba, ndi thermoforming akupanga pulasitiki pamalo athyathyathya.Njira zopangira pulasitiki pamwambapa zitha kugwiritsidwa ntchito pokonza mphira.Komanso, pali madzi monoma kapena polima monga zopangira kuponya, etc. Mwa njira zimenezi, extrusion ndi jekeseni akamaumba ndi ntchito kwambiri ndi zofunika akamaumba njira.
The makina processing kupanga mankhwala pulasitiki ndi kubwereka pulasitiki processing njira ya zitsulo ndi nkhuni, etc., kupanga mankhwala pulasitiki ndi kukula yeniyeni kapena zochepa zedi, ndipo angagwiritsidwenso ntchito ngati ndondomeko wothandiza akamaumba, monga macheka. kudula kwa ma profiles a extruded.Chifukwa cha ntchito zosiyanasiyana za pulasitiki ndi zitsulo ndi matabwa, pulasitiki matenthedwe madutsidwe ndi osauka, coefficient wa kukula matenthedwe, otsika modulus wa elasticity, pamene fixture kapena kuthamanga chida ndi lalikulu kwambiri, zosavuta chifukwa mapindikidwe, kudula kutentha mosavuta kusungunuka, ndi zosavuta kutsatira chida.Chifukwa chake, makina apulasitiki, chida chomwe chimagwiritsidwa ntchito komanso kuthamanga kofananirako kuyenera kutengera mawonekedwe apulasitiki.Njira zomwe zimagwiritsidwa ntchito kwambiri ndi macheka, kudula, kukhomerera, kutembenuza, planing, kubowola, kupera, kupukuta, kukonza ulusi ndi zina zotero.Kuphatikiza apo, mapulasitiki amatha kudulidwa, kubowoleza ndi kuwotcherera ndi ma laser.
Kuphatikizira kupanga zinthu zapulasitiki Njira zophatikizira mbali za pulasitiki ndi kuwotcherera ndi kulumikiza.Njira yowotcherera ndikugwiritsa ntchito kuwotcherera kwamagetsi otentha, kugwiritsa ntchito kuwotcherera kotentha kosungunuka, komanso kuwotcherera kwanthawi yayitali, kuwotcherera kwanthawi yayitali, kuwotcherera kwamphamvu, kuwotcherera kolowera, kuwotcherera akupanga ndi zina zotero.Njira yolumikizira imatha kugawidwa mu flux, resin solution ndi zomatira zotentha zosungunuka molingana ndi zomatira zomwe zimagwiritsidwa ntchito.
Cholinga cha kusinthidwa kwapamwamba pakupanga zinthu zapulasitiki ndikukongoletsa pamwamba pa zinthu zapulasitiki, nthawi zambiri kuphatikiza: kusinthidwa kwamakina, ndiko kuti, fayilo, kugaya, kupukuta ndi njira zina, kuchotsa burr, burr, ndi kukonza kukula;Kumaliza, kuphatikizapo kupaka pamwamba pa mankhwala ndi utoto, kugwiritsa ntchito zosungunulira kuti pamwamba pakhale kuwala, pogwiritsa ntchito zojambula zojambula zojambula pamwamba pa mankhwala, ndi zina zotero;Kugwiritsa ntchito utoto, kuphatikiza utoto wa utoto, kusindikiza ndi masitampu otentha;Golide plating, kuphatikizapo vakuyumu ❖ kuyanika, electroplating ndi mankhwala siliva plating, etc. Pulasitiki processing otentha masitampu ndi kusamutsa mtundu zotayidwa zojambulazo wosanjikiza (kapena chitsanzo filimu) pa otentha mitundu filimu kuti workpiece pansi Kutentha ndi kukakamizidwa.Zida zambiri zapakhomo ndi zomangira, zofunika zatsiku ndi tsiku, ndi zina zambiri, akugwiritsa ntchito njirayi kuti apeze zitsulo zonyezimira kapena matabwa.
Assembly ndi ntchito yosonkhanitsa zigawo zapulasitiki kukhala zinthu zonse ndi gluing, kuwotcherera ndi kulumikiza makina.Mwachitsanzo, mbiri ya pulasitiki imasonkhanitsidwa m'mafelemu awindo apulasitiki ndi zitseko kudzera pa macheka, kuwotcherera, kubowola ndi masitepe ena.
