Cov ductile cam khwb cia hlau castings ua los ntawm cob coated xuab zeb casting los ntawm Tuam Tshoj casting tuam txhab nrogCNC machiningthiab cov kev pabcuam kuaj.
Cov resin coated xuab zeb casting yog dav siv los tsimkev cai castingsnrog cov kev xav tau siab duantsuab xuab zeb casting txheej txheem. Ua ntej ua cov pwm thiab cov tub ntxhais, cov xuab zeb coated tau raug them nrog cov khoom siv cob rau ntawm cov xuab zeb hais. Cov xuab zeb coated kuj hu ua plhaub (core) xuab zeb. Cov txheej txheem thev naus laus zis yog kev sib xyaw cov hmoov thermosetting phenolic tsob ntoo nrog cov xuab zeb nyoos thiab ua kom khov thaum cua sov. Nws tau raug tsim los rau hauv cov xuab zeb coated los ntawm kev siv cov thermoplastic phenolic resin ntxiv rau latent curing agent (xws li urotropine) thiab cov roj nplua nyeem (xws li calcium stearate) los ntawm cov txheej txheem txheej txheej. Thaum cov xuab zeb coated yog rhuab, cov resin coated rau saum npoo ntawm cov xuab zeb hais melts. Nyob rau hauv qhov kev txiav txim ntawm pawg methylene decomposed los ntawm Maltropine, cov molten resin sai hloov los ntawm ib tug linear qauv mus rau ib tug infusible lub cev qauv kom cov coated xuab zeb yog solidified thiab tsim. Ntxiv nrog rau daim ntawv qhuav granular ntawm coated xuab zeb, kuj tseem muaj cov xuab zeb ntub thiab viscous coated.
Resin coated xuab zeb casting muaj cov yam ntxwv hauv qab no
1) Nws muaj lub zog tsim nyog ua haujlwm. Nws tuaj yeem ua tau raws li qhov yuav tsum tau ua rau lub zog siab lub plhaub core xuab zeb, nruab nrab lub zog kub lub thawv xuab zeb, thiab lub zog qis-ferrous alloy xuab zeb.
2) Zoo heev fluidity, zoo moldability ntawm cov xuab zeb cores thiab cov ntsiab lus meej, uas tuaj yeem tsim cov xuab zeb nyuaj tshaj plaws, xws li lub tsho dej xuab zeb xws li lub tog raj kheej taub hau thiab tshuab lub cev.
3) Qhov zoo ntawm cov xuab zeb core yog qhov zoo, compact thiab tsis xoob. Txawm hais tias tsawg dua los yog tsis muaj txheej yog thov, zoo dua nto ntawm castings tau. Qhov tseeb qhov tseeb ntawm castings tuaj yeem ncav cuag CT7-CT8, thiab qhov roughness ntawm Ra tuaj yeem ncav cuag 6.3-12.5μm.
4) Zoo collapsibility, uas yog conducive rau casting tu thiab txhim kho cov khoom ua tau zoo
5) Cov xuab zeb core tsis yooj yim rau nqus dej noo, thiab lub zog ntawm kev khaws cia ntev tsis yooj yim txo, uas yog qhov tsim nyog rau kev khaws cia, kev thauj mus los thiab siv.
Manufacturing txheej txheem ntawm resin coated xuab zeb pwm (core) ua rauplhaub molding:
1. Cov txheej txheem yooj yim ntawm kev tsim coated xuab zeb pwm (core) yog: tig los yog tshuab xuab zeb → crust → xuab zeb tawm → harden → core (pwm) thiab lwm yam.
1) Tig los yog tshuab xuab zeb. Ntawd yog, cov xuab zeb coated yog nchuav rau ntawm lub plhaub pwm los yog tshuab rau hauv lub thawv tub ntxhais los tsim lub plhaub lossis lub plhaub plhaub.
2) Kev tiv thaiv. Lub thickness ntawm lub plhaub txheej yog tswj los ntawm kev kho cov cua kub thiab tuav lub sij hawm.
3) Xuab zeb tawm. Tilt lub pwm thiab lub thawv tub ntxhais kom ua rau cov xuab zeb uas tsis muaj kev cuam tshuam los ntawm lub plhaub uas muaj cua sov, thiab sau nws rov qab siv dua. Txhawm rau ua kom yooj yim tshem tawm cov xuab zeb uas tsis muaj coated, yog tias tsim nyog, siv cov txheej txheem ntawm kev co rov qab thiab tawm mus.
4) Hardening. Nyob rau hauv lub xeev cua sov, thiaj li yuav ua rau lub thickness ntawm lub plhaub zoo ib yam, ua rau nws sib cuag nrog cov nto ntawm lub rhuab plhaub nyob rau hauv ib tug tej lub sij hawm ntawm lub sij hawm mus ntxiv harden.
5) Coj lub hauv paus. Siv lub plhaub tawv tawv thiab lub plhaub plhaub tawm ntawm lub pwm thiab lub thawv tub ntxhais.

▶ Resin Coated Sand Casting Procedures:
✔ Ua Cov Qauv Hlau. Pre-coated resin xuab zeb yuav tsum tau rhuab rau hauv cov qauv, yog li cov qauv hlau yog cov cuab yeej tsim nyog los ua lub plhaub molding castings.
✔ Ua Pre-coated Sand Mould. Tom qab txhim kho cov qauv hlau ntawm lub tshuab molding, cov xuab zeb ua ntej coated yuav raug tua rau hauv cov qauv, thiab tom qab cua sov, cov txheej txheej yuav molten, ces cov xuab zeb pwm ua cov xuab zeb thiab cov cores.
✔ Melting Cov Hlau Casting. Siv induction furnaces, cov ntaub ntawv yuav yaj mus rau hauv cov kua, ces cov tshuaj muaj pes tsawg leeg ntawm cov kua hlau yuav tsum tau soj ntsuam kom phim tus lej thiab feem pua.
✔ Pouring Hlau. Thaum cov hlau melted ua tau raws li qhov yuav tsum tau ua, ces lawv yuav muab nchuav rau hauv lub plhaub pwm. Raws li cov cim sib txawv ntawm cov qauv tsim, lub plhaub pwm yuav muab faus rau hauv cov xuab zeb ntsuab los yog cov txheej txheej.
✔ Txhaj tshuaj tiv thaiv, sib tsoo thiab ntxuav. Tom qab txias thiab solidification ntawm cov castings, cov risers, rooj vag los yog ntxiv hlau yuav tsum tau txiav tawm thiab tshem tawm. Tom qab ntawd cov hlau castings yuav raug ntxuav los ntawm cov khoom siv xuab zeb peening lossis txhaj tshuaj blasting tshuab. Tom qab sib tsoo lub taub hau lub rooj vag thiab cov kab sib cais, cov khoom tiav casting yuav tuaj, tos rau cov txheej txheem ntxiv yog tias xav tau.
