Iyo ductile cast iron castings inogadzirwa neresin yakavharwa jecha kukanda kubva kuChina kukanda kambani ineCNC machininguye mabasa ekuedza.
Iyo resin yakavharwa jecha kukanda inoshandiswa zvakanyanya kugadziracustom castingsnepamusoro zvinodiwa kupfuuragreen sand casting process. Usati wagadzira mold uye core, jecha rakaputirwa rakafukidzwa nefirimu resin yakasimba pamusoro pezvikamu zvejecha. Jecha rakavharwa rinonziwo goko (core) jecha. Muitiro wetekinoroji ndeyekusanganisa nehupfu hwethermosetting phenolic muti nejecha mbishi uye kuomesa kana uchipisa. Yakagadzirwa kuita jecha rakavharidzirwa nekushandisa thermoplastic phenolic resin plus latent curring agent (senge urotropine) uye lubricant (senge calcium stearate) kuburikidza neimwe nzira yekupfekedza. Kana jecha rakaputirwa richipisa, resin yakavharwa pamusoro pezvikamu zvejecha inonyunguduka. Pasi pechiito cheboka re methylene rakasvibiswa neMaltropine, resin yakanyungudutswa inokurumidza kushanduka kubva kune mutsara wakarongeka kusvika kune infusible body structure kuitira kuti jecha rakaputirwa rive rakasimba uye riumbwe. Pamusoro peiyo yakajairika yakaoma granular fomu yejecha rakavharwa, kune zvakare rakanyorova uye viscous rakavharwa jecha.
Resin coated jecha casting ine zvinotevera maitiro
1) Iine akakodzera simba rekuita. Inogona kusangana nezvinodiwa kune yakakwirira-simba shell core jecha, yepakati-simba rinopisa-bhokisi jecha, uye pasi-simba risina-ferrous alloy jecha.
2) Yakanakisa fluidity, yakanaka moldability yejecha musimboti uye yakajeka ratidziro, iyo inogona kuburitsa yakanyanya kuoma jecha cores, senge jecha remvura jecha cores senge cylinder misoro nemitumbi yemuchina.
3) Hunhu hwepamusoro hwejecha core yakanaka, compact uye haina kusununguka. Kunyangwe kana kushoma kana kusavharwa kwakaiswa, zvirinani zvemhando yepamusoro zvekukanda zvinogona kuwanikwa. The dimensional kunyatsoita castings anogona kusvika CT7-CT8, uye pamusoro roughness Ra anogona kusvika 6.3-12.5μm.
4) Kudonha kwakanaka, kunobatsira pakukanda kuchenesa nekuvandudza kuita kwechigadzirwa
5) Iyo jecha musimboti haisi nyore kutora unyoro, uye kusimba kwekugara kwenguva refu hakusi nyore kuderera, iyo inobatsira kuchengetedza, kutakura uye kushandisa.
Magadzirirwo ekugadzira resin yakavharwa jecha mold (core) kugadzirashell molding casting:
1. Nzira yekutanga yekugadzira yakavharwa jecha mold (core) ndeiyi: flip kana kuputira jecha → crust → kuburitsa jecha → kuoma → musimboti ( mold) zvichingodaro.
1) Shandura kana kuputira jecha. Kureva kuti, jecha rakaputirwa rinodururwa paganda mold kana kupeperetswa mukati mebhokisi repakati kugadzira goko kana goko repakati.
2) Encrustation. Ukobvu hweganda reganda rinodzorwa nekugadzirisa kupisa kwekupisa uye kubata nguva.
3) Kubuda kwejecha. Rongedza mold uye bhokisi repakati kuita kuti jecha risina kuvharwa ridonhe kubva pagoko rinopisa, woriunganidza kuti rizoshandiswazve. Kuti zvive nyore kubvisa jecha risina kunyunguduka rakaputirwa, kana zvichidikanwa, nzira yemagetsi yekuzunungusa kumashure uye mberi inogona kugamuchirwa.
4) Kuomesa. Mumamiriro ekupisa, kuitira kuti kukora kwegomba kuve yunifomu, ita kuti ibatane nepamusoro peganda rinopisa mukati meimwe nguva yekuwedzera kuoma.
5) Tora musimboti. Tora iyo yakaomeswa goko chimiro uye shell core kunze kwe mold uye musimboti bhokisi.

▶ Resin Yakavharwa Nejecha Maitiro ekukanda:
✔ Kugadzira Metal Pateni. Iyo pre-yakavharwa resin jecha inoda kupiswa mumapateni, saka mapatani esimbi ndiwo anodiwa ekushandisa kugadzira goko rekuumba castings.
✔ Kugadzira Pre-coated Sand Mold. Mushure mekuisa simbi mapatani pamushini wekuumba, iyo pre-yakavharwa resin jecha inopfurwa mumapateni, uye mushure mekupisa, resin yekupfekedza ichanyungudutswa, ipapo molds yejecha inova yakasimba jecha goko uye cores.
✔ Kunyungudutsa iyo Cast Metal. Uchishandisa masimbi ekupinza, zvinhu zvacho zvaizonyungudutswa kuita mvura, zvino maumbirwo emakemikari esimbi yemvura anofanirwa kuongororwa kuti aenderane nenhamba dzinodiwa uye muzana.
✔ Kudira Simbi. Kana iyo simbi yakanyunguduka inosangana nezvinodiwa, zvino ichadururwa muhombodo dzeganda. Zvichienderana neakasiyana mavara ekugadzira dhizaini, molds magoko anovigwa mujecha rakasvibira kana kurongedzwa nematanho.
✔ Kupfura Kuputika, Kukuya uye Kuchenesa. Mushure mekutonhodzwa uye kusimba kwekukanda, makwikwi, masuwo kana simbi yakawedzerwa inofanira kugurwa uye kubviswa. Ipapo masimbi anocheneswa nejecha rekupenengura kana michina yekupfutidza. Mushure mekugaya musoro wegedhi uye mitsara yekuparadzanisa, zvikamu zvakapedzwa zvekukanda zvaizouya, zvakamirira mamwe maitiro kana zvichidiwa.

▶ Nei Uchisarudza RMC yeShell Mold Casting Machikamu?
✔ Kururamisa uye nekudaro kushandiswa kwezvinhu kwakakwira. Iwe uchawana mambure kana padhuze-neti-chimiro zvigadzirwa mushure megoko rekukanda kukanda, zvichienderana nezvinodiwa zvevashandisi vekupedzisira, hapazove kana kana kushoma machining maitiro anodiwa.
✔ Kuita kurinani kwepamusoro. Nekuda kwezvinyo-tekinoroji zvekugadzira, izvo zvinokandwa kubva kugoko remugodhi zvine yakanyanya kunaka uye yakakwirira yekurongeka kwepamusoro.
✔ Sarudzo yakanaka yakadzikama uchienzanisa nekukanda jecha nekudyara. Iyo shell molding casting ine kuita zvirinani uye pamusoro pane kukanda jecha, nepo iine mutengo wakaderera pane chaiyo yekukanda mari.
