Malangizo a Acrylic Injection Molding Designs

Polima jakisoni akamaumbandi njira yotchuka yopangira zida zolimba, zomveka bwino komanso zopepuka. Kusinthasintha kwake komanso kusasunthika kwake kumapangitsa kuti ikhale njira yabwino kwambiri yogwiritsira ntchito zambiri, kuyambira pamagalimoto kupita ku zida zamagetsi zamagetsi. Mu bukhuli, tiwona chifukwa chake acrylic ali njira yabwino kwambiri yopangira kuwombera, momwe mungapangire zigawo moyenera, komanso ngati kuumba kwa acrylic kuli koyenera pantchito yanu yotsatira.

Chifukwa chiyani polima amawumba jekeseni?

Polymer, kapena Poly (methyl methacrylate) (PMMA), ndi pulasitiki yopangidwa yodziwika bwino chifukwa cha kumveka bwino ngati galasi, kukana kwanyengo, komanso chitetezo chowoneka bwino. Ndizinthu zabwino kwambiri zopangira zomwe zimafuna kukopa kokongola komanso moyo wautali. Ichi ndichifukwa chake ma acrylic amalowa mkatijekeseni akamaumba:

Kutsegula kwa Optical: Imagwiritsa ntchito njira yopepuka pakati pa 91% -93%, ndikupangitsa kuti ikhale m'malo mwagalasi pamapulogalamu omwe amayitanitsa kupezeka bwino.
Kukaniza Nyengo: Kukana kwachilengedwe kwa ma polima ku kuwala kwa UV ndi chinyezi kumawonetsetsa kuti kumakhalabe kowoneka bwino komanso kotetezeka m'malo akunja.
Dimensional Kukhazikika: Imasunga kukula kwake ndi mawonekedwe ake nthawi zonse, zomwe ndizofunikira pakupanga kwamphamvu kwambiri komwe zida zingagwiritsidwe ntchito komanso zovuta zimatha kusiyana.
Kukaniza Chemical: Imagonjetsedwa ndi mankhwala ambiri, kuphatikizapo zotsukira ndi ma hydrocarboni, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito mafakitale ndi zoyendera.
Recyclability: Acrylic ndi 100% yobwezeretsedwanso, yopereka njira ina yothandiza zachilengedwe yomwe ingabwerezedwenso kumapeto kwa moyo wake woyamba.

Momwe Mungakhazikitsire Zigawo za Polima jakisoni Woumba

Popanga zida za acrylic kuwombera, kuganizira mozama zinthu zina kungathandize kuchepetsa zolakwika ndikuwonetsetsa kuti ntchitoyo ikuyenda bwino.

Kusintha kwa Wall Densityeeping

kukhuthala kokhazikika kwa khoma ndikofunikiraacrylic jekeseni akamaumba. Makulidwe olangizidwa a zida za acrylic amasiyana pakati pa 0.025 ndi 0.150 mainchesi (0.635 mpaka 3.81 mm). Kuchulukana kwapakhoma kofananako kumathandizira kuchepetsa ngozi yankhondo ndikutsimikizira kudzaza kwa nkhungu. Makoma ang'onoang'ono amakhalanso oziziritsa mofulumira kwambiri, kuchepetsa kutsika ndi nthawi yozungulira.

Makhalidwe Azinthu & Kugwiritsa Ntchito

Zinthu za polima ziyenera kupangidwa poganizira momwe zimagwiritsidwira ntchito komanso momwe zimakhalira. Zinthu monga kukwawa, kutopa, kuvala, ndi nyengo zimatha kukhudza kulimba kwa chinthucho. Mwachitsanzo, ngati gawolo likuyembekezeredwa kuti lipitirire kulimbana kwakukulu kapena kuwonetseredwa kwachilengedwe, kusankha mtundu wokhazikika ndi kulingalira za mankhwala owonjezera kungathandize kwambiri.

Radi

Kuti muwongolere kusinthika ndikuchepetsa kupsinjika ndi kuyang'ana nkhawa, m'pofunika kupewa mbali zakuthwa mumayendedwe anu. Pazigawo za acrylic, kusunga utali wozungulira wofanana ndi osachepera 25% ya makulidwe a khoma kumalangizidwa. Kuti ukhale wolimba kwambiri, utali wozungulira wofanana ndi 60% wa makulidwe a khoma uyenera kugwiritsidwa ntchito. Njira iyi imathandizira kuteteza ku ming'alu ndikukulitsa kulimba kwa gawo lonselo.

Draft Angle

Monga mapulasitiki ena opangidwa ndi jakisoni, zida za acrylic zimafunikira kolowera kuti zitsimikizire kutulutsa kosavuta kuchokera ku nkhungu ndi mildew. Ngodya yolembera pakati pa 0.5 ° ndi 1 ° nthawi zambiri imakhala yokwanira. Komabe, pamalo owoneka bwino, makamaka omwe amayenera kukhala owoneka bwino, koyenera kuwongolera bwinoko kungakhale kofunikira kuti tipewe kuwonongeka pakutulutsa.

Kulekerera Gawo

Magawo opangidwa ndi jekeseni wa polima amatha kulolerana kwambiri, makamaka pazigawo zing'onozing'ono. Kwa magawo omwe ali pansi pa 160 mm, kukana kwa mafakitale kumatha kusiyanasiyana kuchokera ku 0.1 mpaka 0.325 mm, pomwe kukana kwakukulu kwa 0.045 mpaka 0.145 mm ndikotheka chifukwa cha magawo ang'onoang'ono kuposa 100 mm. Zololera izi ndizofunikira kwambiri pamapulogalamu omwe amafunikira kulondola komanso kufanana.

Kuchepa

Kutsika ndi gawo lachilengedwe la njira yopangira jakisoni, ndipo polima ndizosiyana. Ili ndi chiwopsezo chochepa cha 0.4% mpaka 0.61%, chomwe chili chofunikira kuti chisungidwe molondola. Kuyimira kucheperachepera, mapangidwe a nkhungu ndi mildew ayenera kuphatikiza izi, poganizira zinthu monga kupsinjika kwa jekeseni, kutentha kwa sungunula, ndi nthawi yozizira.
