DIE CASTING PROCESS

Chii chinonzi kufa casting?

Die casting inzira yekukanda simbi, iyo inoratidzwa nekuisa high pressure kusimbi yakanyungudutswa uchishandisa mhango yeforoma. Molds dzinowanzo gadzirwa nepamusoro-simba alloys, uye maitiro aya akafanana nekuumba jekiseni. Mazhinji anofa castings haana iron-isina, senge zingi, mhangura, aluminium, magnesium, lead, tin, uye lead-tin alloys nema alloys awo. Zvichienderana nerudzi rwekukanda kufa, iwe unofanirwa kushandisa inotonhora kamuri yekukanda muchina kana inopisa kamuri yekukanda muchina.

Mutengo wemidziyo yekukanda uye mold wakakwira, saka iyo die-casting process inowanzo shandiswa kugadzirwa kwehuwandu hwehuwandu hwezvigadzirwa. Kugadzira zvikamu zve-die-cast zviri nyore, izvo zvinowanzongoda matanho mana makuru, uye kuwedzera kwemutengo kwemunhu kwakaderera. Die casting inonyanya kukodzera kugadzira nhamba huru yediki uye yepakati-saizi castings, saka kufa casting ndiyo inonyanya kushandiswa mhando yekukanda maitiro. Kuenzaniswa nehumwe matekinoroji ekukanda, iyo inofa-yekukanda nzvimbo yakati sandara uye ine yakakwira dimensional kuenderana.

Zvichienderana nemaitiro echinyakare ekufa-kukanda maitiro, akati wandei akavandudzwa maitiro akazvarwa, kusanganisira isiri-porous die-casting maitiro ayo anodzikisa kuremara kwekukanda uye kubvisa porosity. Inonyanya kushandiswa kugadzira zinc, iyo inogona kuderedza marara uye kuwedzera goho reyakananga jekiseni maitiro. Kune zvakare mitsva yekufa-yekukanda maitiro senge chaiyo kufa-kukanda tekinoroji uye semi-yakasimba kufa-kukanda.

Nezve mold

Hurema hukuru hunogona kuitika mukukanda kufa kunosanganisira kupfeka uye kukukurwa. Zvimwe zvinokanganisa zvinosanganisira kupisa kwekupisa uye kuneta kwekupisa. Kana iyo mold pamusoro paine hurema nekuda kwekuchinja kukuru kwekushisa, kupisa kwemafuta kunoitika. Mushure mekushandisa kwakawanda, kukanganisa kuri pamusoro pe mold kunokonzera kuneta kwekupisa. 

About die-cast metal

Simbi dzinoshandiswa kufa-kandira dzinosanganisira zinc, mhangura, aluminium, magnesium, lead, tin, uye lead-tin alloys. Kunyangwe simbi inofa isingawanzo, inogoneka zvakare. Mamwe masimbi akakosha ekukanda anosanganisira ZAMAK, aluminium-zinc alloy, uye zviyero zveAmerican Aluminium Association: AA380, AA384, AA386, AA390, uye AZ91D magnesium. Hunhu hwemasimbi akasiyana panguva yekukanda kufa ndeaya anotevera:

• Zinc: Simbi iyo iri nyore kufa-yakandwa. Izvo zvine mari kugadzira zvidimbu zvidiki, zviri nyore kupfeka, zvine simba rekumanikidza, purasitiki yakakwira, uye hupenyu hurefu hwekukanda.

 Aluminium: Uremu hwechiedza, kugadzikana kwepamusoro-soro pakugadzira michina yakaoma uye yakatetepa-yakakomberedzwa, yakasimba corrosion resistance, yakanaka mechanical properties, high thermal uye magetsi conductivity, uye simba guru pakupisa kwakanyanya.

 Magnesium: Zviri nyore kugadzirwa, ine yakakwira simba-ku-huremu reshiyo, uye ndiyo yakareruka pakati pezvinowanzo shandiswa die-cast simbi.

• Mhangura: Kuomarara kwepamusoro, kusimba kwakasimba kwegora, yakanakisa michina zvimiro zvezvinowanzo shandiswa kufa-kukanda simbi, kupfeka kuramba, uye simba padyo nesimbi.

 Kutungamira uye Tin: yakakwira density, yakakwirira dimensional kurongeka, inogona kushandiswa seyakakosha anti-corrosion zvikamu. Nezvehutano hweveruzhinji, iyi alloy haigone kushandiswa sechikafu chekugadzira uye kuchengetedza michina. Iyo alloy yemutobvu, tin uye antimony (dzimwe nguva iine chidimbu chemhangura) inogona kushandiswa kugadzira manyorerwo emhando uye bronzing mu letterpress kudhinda.

Sarudzo yekushandisa:

Die-casting zvikamu hazvisisiri kuganhurirwa kuindasitiri yemotokari uye indasitiri yezviridzwa, uye zvishoma nezvishoma yakawedzera kune mamwe maindasitiri, semichina yekurima, indasitiri yezvishandiso zvemuchina, indasitiri yemagetsi, indasitiri yekudzivirira, makomputa, midziyo yekurapa, wachi, makamera, uye zuva nezuva. hardware, etc. Indasitiri, kunyanya: zvikamu zvemotokari, midziyo yefenicha, zvigadziriso zvekugezera (imba yekugezera), zvikamu zvekuvhenekera, matoyi, shavers, zvisungo zvekusungira, zvikamu zvemagetsi uye zvemagetsi, mabhanhire emabhandi, mabheji ekurindira, mabheji esimbi, zvivharo, zipi, nezvimwewo.

Azvakanakira:

1. Hunhu hwakanaka hwechigadzirwa

Kurongeka kwedimensional yekukanda kwakakwira, kazhinji kuenzana ne6 ~ 7, kunyangwe kusvika ku4; kupedzisa kwepamusoro kwakanaka, kazhinji kuenzana ne5 ~ 8; simba uye kuoma kwakakwirira, uye simba rinowanzoita 25 ~ 30% yakakwirira kudarika jecha, asi rinowedzerwa Muyero unoderedzwa ne70%; saizi yakagadzikana, uye kuchinjana kwakanaka; inogona kufa-yakakandwa yakaonda-yakakomberedzwa yakaoma castings.

2. Kubudirira kwekugadzirwa kwepamusoro

3. Excellent economic effect

Nekuda kwehukuru chaihwo hwekufa-kukanda, nzvimbo yacho yakatsetseka uye yakachena. Kazhinji, inoshandiswa zvakananga pasina mechanical processing, kana kuti vhoriyamu yekugadzirisa idiki, saka haisi kungovandudza simbi yekushandiswa kwesimbi, asi inoderedzawo nhamba yakawanda yezvigadzirwa zvekugadzirisa uye maawa evanhu; mutengo wekukanda uri nyore; inogona kusanganiswa kufa-casting nemamwe simbi kana zvisiri zvesimbi . Inoponesa kwete chete gungano maawa-awa asiwo simbi.

Zvakaipa:

Mutengo wemidziyo yekukandira uye molds wakakwira, saka nzira yekufa-casting inowanzo shandiswa kugadzira huwandu hukuru hwezvigadzirwa mumabhechi, uye kugadzirwa kwebatch kudiki hakudhure.

QY Precision ine ruzivo rwakazara muDie Casting process, uye inopa mhinduro dzakasiyana kuzadzisa zvaunoda. Iwe unogona kusarudza iyo yakakodzera kune yako yekupedzisira zvigadzirwa uye musika. Kugamuchirwa tumira yako 2D/3D dhizaini yemahara makotesheni.
