Rau rau cov kev txwv rau kev xaiv pwm
Txhaj mould yog ib lub cuab tam rau kev tsim cov khoom yas. Txhawm rau cia cov khoom ua kom zoo, peb yuav tsum them nyiaj rau qee qhov teebmeem thaum xaiv cov tshuaj pwm.
1. Ntau cov resins thiab cov additives uas muaj kev txhim kho corrosion muaj corrosion teebmeem ntawm cov pwm ntawm cov pwm. Txoj kev txhim kho no ua rau hlau txhuam thiab ntxig rau ntawm cov pwm ntawm lub puab pwm.Yog li no, cov hlau khov kho tiv thaiv yuav tsum siv kom deb li deb tau, los yog cov kab noj hniav yuav tsum raug kho nrog chromium plating thiab npib tsib ciab.
2, zoo tu ncua, gloss rau ntawm qhov chaw ntawm cov tshuaj moulded thiab precision thiab txhaj tshuaj pwm kab noj hniav ntab hnyav tau muaj kev sib raug zoo, tshwj xeeb yog ib co yas ntxiv iav fiber, inorganic muab tub lim thiab qee cov xim, lawv thiab yas yaj hauv cov kis thiab kab noj hniav nrog kev siab tshaj tawm, kev sib txhuam ntawm cov kab noj hniav yog qhov loj heev, yog cov khoom tsis hnav tsis taus, yuav ntev li no hnav thiab ua puas rau qhov zoo.
3, kev ruaj ntseg zoo thaum lub caij txhaj tshuaj, txhaj tshuaj tiv thaiv pwm kom sov siab mus txog 300 tawm ℃ .Txawm lub hom phiaj no, siv cov cuab yeej steel (cov tshuaj tua hluavtaws) uas ua kom zoo li ntev tau.Yog li, cov khoom siv microstructure yuav hloov, ua rau muaj kev txhaj tshuaj pauv loj.
4. Yuav kom luv tau cov voj voog thiab tsim kho kom zoo dua, cov ntaub ntawv puav yuav tsum tau ua kom yooj yim tiav rau hauv cov duab thiab cov duab yuav tsum tau kos duab.
5. Kev ua zoo ntawm kev sib paug ntawm qhov txhaj tshuaj molded feem ntau yuav tsum muaj qhov zoo ci ntsa iab thiab ntu zus, yog li qhov roughness ntawm cov kab noj hniav yog qhov yuav tsum tau me me. Nyob rau hauv no txoj kev, cov kab qhov kab noj hniav yuav tsum tau ua tiav, xws li polished thiab av.Yog li ntawd, cov hlau xaiv yuav tsum tsis txhob muaj cov tawv impurities thiab pores.
6. Txhawm rau txhawm rau txhim kho txoj kev hnyav thiab hnav tsis tau, feem ntau cov pwm txhaj tshuaj yuav tsum tau kho cua sov. Txawm li cas los, qhov kev kho mob no yuav tsum ua kom me me hloov me me heev.Yog li no, sim siv cov tshuab ua ntej cov tawv uas yuav tsum tau machined.
