1. hydraulic piston qws machining txheej txheem
Txoj hlua khi yog ua los ntawm 35 steel ua: muaj kev sib txuam txias tawm ua ib txoj kev xa mus rau ib qho kev sib zog ua ntej sab nrauv hardening ib qho kev sib tsoo ua ntej txheej voj voog ntawm kev sib tsoo ua ntej cylindrical sab nraud sib txig super xov chrome plating rau nplua grinding tempering hydrogen. Yuav kom txhim kho tau qhov zoo ntawm qhov chaw zoo thiab kev qis ntawm piston pas nrig, qhov txheej txheem superfine tiav ua ntej chromium plating.
2. Piston pas nrig electroplating txheej txheem
Ua ntej plating kuaj - khib ntsia - cov tshuaj degreasing, electrolysis degreasing - ntxuav - Pickling - dej - tshuab ua kom lub caij - piston qws chrome - ub ntxuav - kev ntxuav - tshem tawm khib - Kuaj
