1. Kupanga jakisoni wa mphira: Kupanga jakisoni wa mphira ndi njira yopangira momwe zinthu za rabara zimayikidwa mwachindunji kuchokera ku mbiya ya vulcanization.Ubwino wopangira jakisoni wa mphira ndi: ngakhale ndi ntchito yapakatikati, kuwongolera kumakhala kwakanthawi, kupanga bwino ndikwambiri, njira yokonzekera yopanda kanthu imathetsedwa, kulimba kwa ntchito kumakhala kochepa, ndipo mtundu wazinthu ndi wabwino kwambiri.
2. Kujambula jekeseni wa pulasitiki: Kujambula kwa pulasitiki ndi njira yopangira pulasitiki.Pulasitiki yosungunuka imalowetsedwa mu nkhungu ya zinthu zapulasitiki ndi kukakamizidwa, ndipo zigawo zapulasitiki zomwe zimafunidwa zimapezedwa ndi kuzizira ndi kuumba.Pali makina opangira jakisoni wamakina odzipereka kuti apange jekeseni.Pulasitiki yomwe imagwiritsidwa ntchito kwambiri masiku ano ndi polystyrene.
3. Kujambula ndi jekeseni: Chojambula chotsatira nthawi zambiri chimakhala chomaliza, ndipo palibe kukonza kwina komwe kumafunika musanayike kapena kugwiritsidwa ntchito ngati chomaliza.Zambiri, monga mabwana, nthiti, ndi ulusi, zimatha kupangidwa popanga jekeseni imodzi.
Kumangira jekeseni ndi nsapato yopangidwa ndi makina.Pambuyo pamwamba kumangiriridwa pa aluminiyamu komaliza, nthawi zambiri mwachindunji jekeseni PVC, TPR ndi zipangizo zina ndi makina turntable kupanga yekha pa nthawi imodzi.Masiku ano, palinso PU (mankhwala dzina polyurethane) jekeseni akamaumba (makina ndi nkhungu ndi General jekeseni akamaumba ndi osiyana).
Ubwino: Chifukwa amapangidwa ndi makina, zotulutsa zake ndi zazikulu, kotero mtengo wake ndi wotsika.
Zoipa: Ngati pali masitayelo ambiri, zimakhala zovuta kusintha nkhungu, nsapato zimakhala zovuta kupanga, ndipo palibe nsapato zoziziritsa zozizira zokhala ndi luso lapamwamba, choncho nthawi zambiri zimakhala zoyenera kulamula ndi kalembedwe kamodzi kokha.
Cholinga, ntchito ndi zotsatira za kutentha, kuthamanga, kuthamanga ndi kuzizira
● Momwe kusintha kwa makina opangira jekeseni kumakhudzira ndondomeko ndi khalidwe
● Konzani zosintha zowongolera zowononga
● Kudzazidwa kwa masitepe ambiri ndi kulamulira kwapakati pazigawo zambiri;chikoka cha crystallization, amorphous ndi ma molecular / fiber orientation pa ndondomeko ndi khalidwe
● Mphamvu ya kupsyinjika kwamkati, kuzizira ndi kuchepa kwa pulasitiki pa ubwino wa zigawo za pulasitiki
Rheology ya mapulasitiki: momwe mapulasitiki amayendera, kuyang'ana ndikusintha kukhuthala, kukameta ubweya ndi ma cell / fiber
● Ubale pakati pa kuthira, dongosolo lozizira, kapangidwe ka nkhungu ndi njira yopangira jekeseni
Mphepete mwa shrinkage, shrinkage, unsaturated nkhungu, burr, weld line, waya wa siliva, chizindikiro chopopera, kutentha, warpage deformation, kusweka / kusweka, kukula chifukwa cha kulolerana ndi kufotokozera zina zomwe zimapangidwira jekeseni, kufufuza chifukwa, ndi kupanga nkhungu, kuumba Mayankho. pakuwongolera njira, kapangidwe kazinthu ndi zinthu zapulasitiki.
● Kusanthula ndi njira zothanirana ndi kusowa kwa zomatira ndi nkhungu zopanda unsaturated kuzungulira mbali zomangira jekeseni
●Kusanthula kwazifukwa ndi mayankho
● Kusanthula kwazomwe zimayambitsa ndikuthana ndi kuchepa kwapamtunda ndi ming'oma (vacuum bubble) ya ziwalo zoumbidwa jekeseni.
●Kusanthula ndi njira zothetsera mikwingwirima yasiliva (maluwa amtengo wapatali, kuwaza kwamadzi), kutentha, ndi mikwingwirima ya gasi
●Kusanthula kwazomwe zimayambitsa ndi kuletsa kuphulika kwa madzi ndi zizindikiro zotuluka (zizindikiro) pamwamba pazigawo zoumbidwa jekeseni.
● Kusanthula kwazomwe zimayambitsa ndi kutsutsa kwa zizindikiro za madzi (mizere yowotcherera) ndi zizindikiro zopopera (zizindikiro za njoka) pamwamba pazigawo zoumbidwa jekeseni.
●Kufufuza ndi njira zothetsera ming'alu ya pamwamba (kung'ambika) ndi kuyera pamwamba (kuphulika pamwamba) kwa ziwalo zopangidwira
● Kusanthula kwazomwe zimayambitsa komanso zotsutsana ndi kusiyana kwa mitundu, kusawoneka bwino, kusakanikirana kwamitundu, mikwingwirima yakuda ndi mawanga akuda pamwamba pazigawo zoumbidwa jekeseni.
● Kusanthula kwazomwe zimayambitsa ndi zotsutsana ndi kusinthika kwa warping ndi kupsinjika kwa mkati mwa ziwalo zoumbidwa ndi jekeseni
● Kusanthula kwazomwe zimayambitsa ndi zotsutsana ndi kupatuka kwa magawo opangidwa ndi jekeseni
● Kusanthula kwazomwe zimayambitsa ndikuthana ndi ma jakisoni omwe amamatira ku nkhungu, kukokera (kupsyinjika) ndi kukoka koyera.
● Kusanthula kwazomwe zimayambitsa ndi zotsutsana ndi kusaonekera kosakwanira komanso mphamvu zosakwanira (kuphwanyika kwa brittle) kwa ziwalo zoumbidwa ndi jakisoni.
● Kusanthula chifukwa ndi zotsutsana ndi malo ozizira ndi kupukuta (kusanjikiza) pamwamba pa jekeseni wopangidwa ndi magawo
● Kusanthula ndi njira zothanirana ndi kuyika kwachitsulo kosauka kwa magawo opangidwa ndi jekeseni
●Kusanthula ndi njira zowongolerera kudontha kwa mphuno (mphuno yothamanga), kutayikira kwa guluu, kujambula mawaya a nozzle, kutsekeka kwa mphuno, komanso kulephera kutsegula nkhungu.
● Kugwiritsa ntchito ukadaulo wa CAE mold flow analysis kuti athetse mwachangu komanso moyenera mavuto omwe ali pamalowo pakuumba jekeseni
