Nqus casting steel cua ntsawj ntshab iav vaj tsev rau cov tsheb thauj khoom nrog CNC machining thiab kev cai taillor-made cov kev pab cuam. Cam khwb cia hlau v txheej txheem castings txhais tau hais tias cov casting qhov chaw tsim los ntawmlub tshuab nqus tsev casting txheej txheemnrog cov ntaub ntawv ntawm cam khwb cia hlau.Chromium-molybdenum cam khwb cia hlau yog dav siv nyob rau hauv kev lag luam teb nrog kuj zoo heev mechanical zog. Qhov sib ntxiv ntawm molybdenum rau chromium hlau tuaj yeem ua rau kom lub zog ntawm cov hlau castings tsis muaj qhov cuam tshuam loj rau qhov cuam tshuam ntawm cov cam khwb cia hlau. Chromium-molybdenum cam khwb cia hlau muaj qhov kub thiab txias kev ua haujlwm zoo heev thiab nkag siab tsis kam. Tom qab quenching thiab tempering los yog normalizing kev kho cua sov, chromium-molybdenum cam khwb cia hlau tuaj yeem tau txais cov khoom zoo heev. Molybdenum tuaj yeem txhim kho lub hardenability ntawm cam khwb cia hlau thiab txo cov temper brittleness ntawm cam khwb cia hlau. Chromium-molybdenum cam khwb cia hlau yog siv rau loj-section castings thiab steel castings uas yuav tsum tau sib sib zog nqus hardening.
Nqus molding casting, tseem hu ua tsis zoo siab molding txoj kev, nqus sealing molding txoj kev, los yog V txheej txheem rau luv luv. Qhov no yog ib yam tshiab ntawm lub cev qauv qauv. Txoj kev tsis zoo siab molding txoj kev siv lub siab sib txawv ntawm sab hauv thiab sab nraud ntawm cov pwm kom ceev cov xuab zeb qhuav thiab xoob xoob ua ke kom tau cov pwm nrog ib qho kev xav tau thiab muaj zog.
Nqus casting tso cai rau kev tsim cov khoom me me ntawm cov pwm zoo hauv ntau hom polyurethane resins uas rov ua dua qhov kev ua tau zoo ntawm cov yas yas yam tsis muaj tus nqi siab ntawm cov cuab yeej nyuaj cuam tshuam nrog kev txhaj tshuaj molding. Cov txheej txheem pib nrog ua pwm los ntawm encapsulating tus qauv qauv hauv ob feem ua kua silicone roj hmab. Tom qab ntawd lub tshuab nqus tsev yog siv los tshem tawm cov cua uas nyob hauv qhov cub, tom qab ntawd nws kho tau hauv qhov cub. Master qauv tuaj yeem los ntawm ntau lub tshuab luam ntawv 3D nrog rau stereolithography. Thaum cov silicone kho tau zoo, cov pwm raug txiav qhib los ua ib txoj kab sib cais, tus qauv qauv raug tshem tawm uas tawm hauv pwm kab noj hniav zoo kawg nkaus replicating tus qauv qauv. Ua ib feem, cov pwm ntu tau muab rov qab ua ke, ruaj ntseg, pre-rhuab thiab muab tso rau hauv lub tshuab nqus tsev casting chamber. Ob lossis peb feem resin yog hnyav, xim ntxiv yog tias xav tau thiab cov khoom siv tau muab tso rau hauv lub tshuab tsis siv neeg lub tshuab nqus tsev casting. Nyob rau lub sijhawm no, lub tshuab nqus tsev casting yuav siv sij hawm dhau cov txheej txheem los sib tov cov khoom sib xyaw thiab nqus cov qauv. Thaum qhov no ua tiav qhov casting yog kho. Tom qab kho, cov pwm ntu tuaj yeem sib cais thiab tshem tawm ib feem. Txhua yam uas tseem tshuav yog rau lubcasting qhov chawyuav tsum tau txiav thiab ua tiav raws li qhov xav tau.
