Plhaub Pwm Castings

Plhaub molding casting siv pre-coated resin xuab zeb casting los tsim cov pwm pwm. Nws siv lub plhaub kub molding (cov txheej txheem ci) thiab coated core ua ntej cov hlau molten ncuav rau hauv cov pwm npaj. Lub ntsiab molding khoom yog pre-coated phenolic resin xuab zeb, uas yog kim tshaj li ntsuab xuab zeb thiab furan resin xuab zeb. Ntxiv mus, cov xuab zeb no tsis tuaj yeem siv dua. Yog li ntawd, lub plhaub molding castings muaj nqi ntau dua li cov xuab zeb casting. Txawm li cas los xij, piv rau cov xuab zeb ntsuab, lub plhaub molding castings muaj ntau yam zoo xws li siab dua qhov ntev, qhov zoo ntawm qhov zoo thiab tsawg dua qhov tsis xws luag. Lub plhaub moulding casting txheej txheem tshwj xeeb yog tsim tshwj xeeb rau kev tsim cov castings ntawm cov duab nyuaj, cov hlab ntsha siab, qhov hnyav rhiab thiab castings uas yuav tsum tau ua tiav qhov zoo tshaj plaws.
