China OEM tsika kukandwa simbishell mold casting productsnemasevhisi eCNC machining, kurapwa kwekupisa uye kurapwa kwepamusoro.
Shell molding castingprocess inodaidzwa zvakare kunzi pre-coated resin jecha kukanda process, inopisa goko rekuumba castings kana core casting process. Chinhu chikuru chekuumba ndeye pre-yakavharidzirwa phenolic resin jecha, iyo inodhura kupfuura jecha rakasvibirira uye furan resin jecha. Uyezve, jecha iri harigone kushandiswazve.
Furan resin inoomesa jecha rekukanda maitiro (nobake process) inoshandisa furan resin yakavharwa jecha kugadzira mold yekukanda. Mushure mekusanganisa jecha rekutanga (kana jecha rakadzoserwa), mvura furan resin uye mvura inokonzeresa zvakaenzana, uye kuizadza mubhokisi repakati (kana jecha bhokisi), wobva waisimbisa kuti iome kuita mold kana mold mubhokisi repakati (kana jecha). bhokisi) pakupisa kwekamuri. Ipapo iyo yekukanda mold kana kukanda core yakaumbwa, iyo inonzi self-hardening inotonhora-core box molding (core), kana self-hardening nzira (core).
Nekuti mold inoumbwa pakudziya kwekamuri uye pasina chikonzero chekupisa, iyo yekuzviomesa jecha kukanda kunonziwo kwete-kubikira casting process. Iyo yekuzviomesa nzira inogona kukamurwa kuita acid-catalyzed furan resin uye phenolic resin jecha self-hardening nzira, urethane resin jecha self-hardening nzira uye phenolic monoester self-hardening nzira.
Sejecha rinozviomesa bhokisi rinosungira jecha, jecha refuran resin ndiro rekutanga uye parizvino rinonyanya kushandiswa sejecha rekugadzira binder muChinese foundry. Huwandu hweresin inowedzerwa mujecha rekuumbwa kazhinji 0.7% kusvika 1.0%, uye huwandu hweresin yakawedzerwa mujecha repakati kazhinji 0.9% kusvika 1.1%. Zvirimo zvemahara aldehyde mu furan resin zviri pazasi 0.3%, uye mamwe mafekitori adzika kusvika pazasi 0.1%. Munzvimbo dzakavambwa muChina, iyo furan resin inoomesa jecha yasvika padanho repasirese zvisinei nemaitiro ekugadzira uye nepamusoro pemhando yekukanda.

Ductile cast iron, iyo inonziwo nodular cast iron, spheriodal graphite cast iron kana kungoti SG iron kwenguva pfupi, inomiririra boka resimbi yakakandwa. Nodular cast iron inowana nodular graphite kuburikidza ne spheroidization uye inoculation kurapwa, iyo inobudirira inovandudza ma mechanic properties yesimbi yakakandwa, kunyanya plastiki uye kuoma, kuitira kuti uwane simba rakakwirira kudarika carbon steel.
Ductile iron castingsIva nekuita kurinani kwekuvhunduka kupfuura kabhoni simbi, nepo kabhoni simbi castings ine zvirinani weldability. Uye kune imwe nhanho, iyo ductile iorn castings inogona kunge iine mamwe maitiro ekupikisa kupfeka uye ngura. Saka iyo ductile iron casting inogona kushandiswa kune dzimwe dzimba dzepombi kana masisitimu ekupa mvura. Nekudaro, isu tichiri kuda kuita matanho ekudzivirira kubva pakupfeka uye ngura.
Ductile iron haisi chinhu chimwe chete asi chikamu cheboka rezvinhu zvinogona kugadzirwa kuti zvive nehuwandu hwezvinhu kuburikidza nekutonga kwe microstructure. Izvo zvinowanzotsanangudza hunhu hweboka iri rezvinhu chimiro chegraphite. Mune ductile irons, iyo graphite iri muchimiro chemanodule kwete maflakes sezvairi mugrey iron. Iyo yakapinza chimiro chemaflakes e graphite inogadzira kushushikana pfungwa mukati mesimbi matrix uye yakatenderedzwa chimiro chemanodule zvishoma, nekudaro kuvharidzira kusikwa kwekutsemuka uye nekupa iyo inosimudzira ductility inopa alloy zita rayo. Saka kazhinji kutaura, kana iyo ductile iron ichigona kuzadzisa zvaunoda, iyo ductile iron inogona kuve yako yekutanga sarudzo, pachinzvimbo chekabhoni simbi yekukanda kwako.

Zvakanakira zveFuran Resin Yakavharwa Jecha Kuzviomesa-Kuumba Kukandira:
1) Kuvandudza kurongeka kwedimensional yekukanda uye kushata kwepamusoro.
2) Kuomeswa kwejecha (core) jecha hakudi kuomeswa, izvo zvinogona kuchengetedza simba, uye matanda asingadhuri kana epurasitiki mabhokisi epakati uye matemplate anogona kushandiswa zvakare.
3) Self-hardnening molding jecha iri nyore kubatanidza uye kudonha, nyore kuchenesa castings, uye jecha rekare rinogona kushandiswazve uye kushandiswa zvakare, izvo zvinoderedza zvakanyanya kusimba kwekushanda kwepakati kugadzira, kuenzanisa, kudonha kwejecha, kuchenesa uye zvimwe zvinongedzo, uye zviri nyore kuona mechanization kana otomatiki.
4) Iyo yakawanda chikamu cheresin mujecha ingori 0.8% ~ 2.0%, uye mutengo wakakwana wezvigadzirwa zvakaderera.
Nemhaka yekuti nzira yekuzviomesa ine zvakawanda zvezvikomborero zvakasiyana-siyana zvataurwa pamusoro apa, nzira yekuzviomesa haingoshandiswi chete pakugadzirwa kwepakati, asiwo inoshandiswa pakukanda kuumba. Iyo inonyanya kukodzera chidimbu chimwe chete uye diki kugadzirwa kwebatch, uye inogona kugadzira simbi yakakandwa, simbi yakakandwa uye isiri-ferrous alloy castings. Mamwe maChinese akawanikwa akatsiva zvachose zviumbwa zvevhu rakaoma rejecha, zviumbwa zvejecha resimende, uye zvishoma zvakatsiva zviumbwa zvejecha remvura.
