High Purity Graphite Molds
Traditional composite molds anowanzo gadzirwa nesimbi.Nekudaro, kubva pakuona kwekugadzira mold uye yavo yavanoda kushandisa marudzi aya eforoma anonetseka kutora maumbirwo akaomarara uye kushanda nezvinhu zvinoumbwa.Uyu ndiwo mugumisiro wezvisingaenderani nemafuta ekuwedzera coefficients pakati pe mold pachayo uye zvinhu zvakamira mukati.Naizvozvo, graphite yakabuda seyekutanga sarudzo yekugadzira mold nekuda kweinoda muviri nemakemikari zvimiro.Jitai inotengesa huwandu hwakakura hwetsika yakakwirira kuchena graphite molds iyo inogona kuderedza zvakanyanya mutengo wechikamu kune vatengi vedu.
Graphite icrystalline fomu ye element carbon ine anotevera maitiro:
1. Excellent thermal uye magetsi conductivity;
2. Inopesana nemakemikari ekuora uye haaiti nyore nyore nemhando dzakasiyana dzesimbi
3. Kuderera kwekuwedzera kwekuwedzera kwemafuta uye kugadzikana kwakanaka kwekushisa
4. Ideal lubrication uye kupfeka kuramba
5. Inoita zvakanaka mukupisa kwakanyanya (yakawanda yemhangura yesimbi matrix sintering tembiricha iri pamusoro pe800 ℃).Simba rinowedzera panguva imwe chete nekuwedzera kwekushisa
6. Kuita kwakanaka kwekugadzira michina, kunogona kushandiswa kune molds ane maumbirwo akaoma uye mumamiriro ezvinhu apo kufanirwa kwepamusoro kunodiwa.
1.Inoshandiswa kuenderera mberi uye semi-inopfuurira kukanda kwesimbi isina-ferrous.Pamusana pehutano hwakanaka hwekupisa uye kuzvidzora kwehutano hwezvinhu, ukuru hweingot hunoramba hwakarurama, nzvimbo yacho inoramba yakatsetseka, uye chimiro chayo chekristalline chinoramba chiri yunifomu kunyange mushure mekuputika kwakawanda.Izvi zvinobvumira kuwedzera kumhanya kwekukanda, kuve nechokwadi chekuti inotevera maitiro anogona kutanga nekukasira kutevera.Izvi zvinovandudza zvakanyanya kuwanda kwegoho uye kunaka kwechigadzirwa.
2. Molds for pressure casting: Artificial graphite yakashandiswa zvinobudirira pakukandira simbi isina-ferrous.Semuyenzaniso, zinc alloy uye copper alloy castings inogadzirwa nekumanikidza kukanda mold yezvakagadzirwa graphite zvinhu zvinowanzo shandiswa muzvikamu zvemotokari.
3. Graphite molds for centrifugal casting: Graphite molds dzakashandiswa zvinobudirira mukukanda centrifugal.Makambani eUS akashandisa zviumbwa zvemagraphite zvine mukobvu wemadziro anodarika 25mm kusvika pakati pemakwenzi ebhuronzi, mabhushi, uye maoko.
4. Zviumbwa zvekutsikirira zvinopisa: Iyo artificial graphite inoshandiswa mukutsikirira inopisa ine maitiro maviri ekumanikidza sintering ye simende carbides:
A) Kana tembiricha panguva yekudzvanya yakawedzera kusvika 1350 kusvika 1450 ℃, iyo inodiwa unit pressure inogona kuderedzwa kusvika 1/10 yezvaizodiwa kana mold ichitonhora.
B) Kudzvanya uye kupisa kunoitwa panguva imwe chete, uye dense sintered muviri unogona kuwanikwa mushure menguva pfupi yekupisa.
5. Molds yekuumba girazi: graphite zvinhu zvave zvakakosha mold zvinhu pakushanda negirazi.Inogona kushandiswa kugadzira molds yegirazi machubhu, elbows, funnels uye akasiyana mamwe mafomu.
6. Sintering molds uye mamwe madhaimani sintering molds: Nekuda kwekuderera kwekupisa kwekuwedzera kweartificial graphite, sintering molds uye mabhuraketi e transistors anogona kugadzirwa.Iko zvino yave kushandiswa zvakanyanya uye yave chinhu chakakosha pakusimudzira indasitiri yesemiconductor.
Kuenzanisa kwekuita kwezvinowanzo shandiswa mold kugadzirisa zvinhu uye composite zvinhu
