Nhungamiro yeAcrylic Injection Molding Designs

Polymer jekiseni kuumbainzira yakakurumbira yekugadzira zvikamu zvinosimba, zvakajeka, uye zvisingaremi. Kuita kwayo kwakasiyana-siyana uye kusimba kunoita kuti ive sarudzo yepamusoro kune akawanda maapplication, kubva kuzvinhu zvemotokari kusvika kune zvemagetsi zvevatengi. Mugwaro iri, isu tichatarisa kuti sei acrylic iri sarudzo yepamusoro yekuumbwa kwepfuti, chaizvo magadzirirwo ezvikamu zvakanaka, uye kana acrylic kupfura kuumba kwakakodzera kune rako rinotevera basa.

Sei kushandisa polymer kuumba jekiseni?

Polymer, kana Poly (methyl methacrylate) (PMMA), ipurasitiki yekugadzira inozivikanwa nekujeka kwayo segirazi, kuramba kwemamiriro ekunze, uye kuchengetedzeka kwechimiro. Icho chinhu chakanakisa kune zvigadzirwa zvinoda zvese aesthetic kukwezva uye hupenyu hurefu. Heino chikonzero nei acrylic akamira mukatijekiseni kuumba:

Optical Openness: Inoshandisa gwara rakareruka riri pakati pe91% -93%, zvichiita kuti rive rakatanhamara kutsiva girazi muzvikumbiro zvinodaidzira kuvepo kwakajeka.
Weather Resistance: Polymer's zvese-zvakasikwa kuramba kune UV mwenje uye hunyoro inoita shuwa kuti inoramba yakajeka uye yakachengeteka zvakare munzvimbo dzekunze.
Dimensional Kugadzikana: Inochengetedza hukuru hwayo uye chimiro nguva dzose, izvo zvakakosha pakugadzirwa kwepamusoro-vhoriyamu inomhanya uko zvishandiso zvinogona kushandisa uye matambudziko anogona kusiyana.
Chemical Resistance: Inoshingirira kumakemikari akawanda, anosanganisira zvekugezesa uye mahydrocarbon, zvichiita kuti ive yakakodzera kushandiswa kweindasitiri nekufambisa.
Recyclability: Acrylic ndeye 100% inoshandiswazve, ichipa eco-inoshamwaridzika imwe nzira iyo inogona kudzokororwa pakupera kwekutanga kwayo kutenderera kwehupenyu.

Maitiro ekurongedza Zvikamu zvePolymer Injection Molding

Paunenge uchigadzira zvikamu zve acrylic kupfura kuumbwa, kufunga zvine hungwaru kwezvimwe zvinhu zvinogona kubatsira kuderedza hurema uye kuve nechokwadi chekubudirira kugadzirwa kunomhanya.

Wall Densityeeping

a yenguva dzose madziro ukobvu kwakakosha mukatiacrylic jekiseni kuumba. Ukobvu hunorayirwa hwezvikamu zve acrylic hunosiyana pakati pe0.025 uye 0.150 inches (0.635 kusvika 3.81 mm). Uniform wall surface density inobatsira kudzikisira njodzi ye warping uye inovimbisa nani kuzadza mold. Madziro akatetepa zvakare anotonhorera nekukurumidza zvakanyanya, achidzikisa contraction uye kutenderera nguva.

Chigadzirwa Behaviour & Kushandisa

Polymer zvinhu zvinofanirwa kugadzirwa zvine chinangwa chekushandiswa uye mamiriro ekunze mupfungwa. Zvinhu zvakadai sekudonha, kuneta, kupfeka, uye mamiriro ekunze zvinogona kukanganisa kusimba kwechinhu. Semuenzaniso, kana chikamu ichi chichitarisirwa kuchengetedza kusawirirana kwakanyanya kana kuratidzwa kwezvakatipoteredza, kutora mhando yakasimba uye kufunga nezvekuwedzera marapirwo kunogona kuvandudza kushanda zvakanaka.

Radii

Kuti uvandudze kuumbwa uye kuderedza kushushikana nekufunganya kutarisa, zvakakosha kuti udzivise mipendero yakapinza muchimiro chako. Kune zvikamu zve acrylic, kuchengetedza radius yakaenzana neinenge 25% yemadziro emadziro ukobvu kunokurudzirwa. Kuti unyatso kuomarara, radius yakaenzana ne60% yehukobvu hwemadziro inofanira kushandiswa. Iri zano rinobatsira mukudzivirira kubva pakatsemuka uye kuwedzera kusimba kwese kwechikamu.

Draft Angle

Kufanana nemamwe akasiyana-siyana akaumbwa-akaumbwa mapurasitiki, acrylic zvinhu zvinoda dhizaini kona kuti ive nechokwadi chekuburitsa kubva mukuvhuvhu uye mildew. Kona yekunyora iri pakati pe0.5 ° ne1 ° inowanzokwana. Nekudaro, kune nzvimbo dzakapfava, kunyanya idzo dzinoda kuramba dzakajeka, zvirinani dhizaini angle inogona kuve yakakosha kudzivirira kukuvadzwa panguva yejection.

Chikamu Kushivirira

Polymer jekiseni-akaumbwa zvikamu zvinogona kuwana kushivirira kukuru, kunyanya kune zvidiki zvikamu. Kune zvikamu zviri pasi pe160 mm, kupikisa kwemaindasitiri kunogona kusiyana kubva pa0.1 kusvika 0.325 mm, nepo kupokana kukuru kwe0.045 kusvika 0.145 mm kunogoneka kune zvikamu zvidiki saizi kupfuura 100 mm. Uku kushivirira kwakakosha kune zvikumbiro zvinoda kunyatsoita uye kufanana.

Kuderera

Kudonhedza chikamu chechisikigo chejekiseni rekuumba maitiro, uye polymer haina mutsauko. Iyo ine yakaderera shrinkage mwero we0.4% kusvika 0.61%, iyo yakakosha pakuchengetedza dimensional kurongeka. Kumiririra kuderera, mold uye mildew magadzirirwo anofanirwa kusanganisira ichi chinhu, tichifunga nezve majekiseni kushushikana, kunyungudika tembiricha, uye nguva yekutonhora.
