Q: Dab tsi yog qhov tseem ceeb ntawm kev tuag casting pwm yuav muaj?
A: Thermal cracking, khoom sticking, yaig, deformation, slag clogging, flash, kab noj hniav khawb, tsis sib xws.
Q: Dab tsi yog lub neej ib txwm muaj ntawm kev tuag casting pwm hauv kev txhaj tshuaj?
A: General zinc / aluminium alloy pwm kawg 80,000-150,000 txhaj tshuaj; precision pwm tuaj yeem ncav cuag 200,000-300,000 txhaj tshuaj.
Q: Vim li cas thiaj tuag- cov khoom cam khwb cia tsim flash thiab burrs?
A: Ntau dhau pwm clamping qhov sib txawv, tsis txaus locking quab yuam, pwm deformation thiab parting nto hnav.
Q: Dab tsi ua rau qhov chaw lo rau pwm?
A: Tsis sib luag tso tawm tus neeg sawv cev txau, pwm pwm kub dhau, cov kab noj hniav ntxhib thiab cov dej ntau dhau.
Q: Yuav ua li cas thermal cracking tshwm sim ntawm tuag casting pwm?
A: Kev ntxhov siab loj los ntawm kev rov ua cua sov thiab txias, kev kho cua sov tsis zoo ntawm pwm hlau thiab tsis txaus preheating.
Q: Yuav ua li cas txuas lub neej kev pab cuam ntawm tuag casting pwm?
A: Txais yuav hwm kub ua haujlwm pwm hlau, txheej txheem kev kho cua sov, preheating kom zoo, kev saib xyuas tsis tu ncua thiab cov qauv tso tawm tus neeg sawv cev txau.
Q: Cov kev kho deg dab tsi yuav tsum tau ua rau tuag casting pwm?
A: Nitriding, carburizing, polishing, nyuaj chrome plating thiab PVD txheej los txhim kho hnav tsis kam thiab tiv thaiv- ua haujlwm ua haujlwm.
Q: Dab tsi yog qhov txiaj ntsig ntawm kev tsim pwm pwm txias txias?
A: Ib feem shrinkage, porosity, deformation, lub sij hawm mus sij hawm ntev thiab yooj yim pwm tawg.
Q: Cov teeb meem dab tsi tshwm sim los ntawm qhov tsis zoo ntawm cov pwm tuag casting?
A: Ib feem porosity, burnt marks, tsis tiav filling thiab txo txhua yam zog.
Q: Puas tuaj yeem pwm hlau sib koom rau zinc alloy thiab aluminium alloy tuag casting?
A: Tsis pom zoo. Aluminium alloy coj muaj zog corrosion thiab yaig, yuav tsum tau siab dua - qib kub ua haujlwm steel.
Q: Vim li cas qhov tuag casting pwm khawb qhov nto?
A: Cavity burrs, tsis txaus polishing, nruj ejector tus pin haum thiab adhered hlau carbon deposits.
Q: Dab tsi yog qhov kev saib xyuas txhua hnub ntawm kev tuag casting pwm suav nrog?
A: Ua kom huv si ntawm qhov chaw, tshawb xyuas qhov grooves, polish me ntsis khawb, tshuaj xyuas cov ejector pins thiab ua xeb- pov thawj cia.
Q: Qhov zoo tshaj plaws pwm preheating kub yog dab tsi?
A: Zinc alloy: 180-220 degree; Aluminium alloy: 200-260 degree.
Q: Dab tsi yog qhov cuam tshuam ntawm kev khiav tsis zoo thiab qhov rooj tsim?
A: Kev sau tsis zoo, huab cua hnyav, qhov tsis sib xws ntawm phab ntsa tuab thiab ntau dua qhov tsis lees paub.
Q: Qhov twg yog qhov tseem ceeb kho ntawm tuag casting pwm?
A: Parting nto, qhov grooves, tawg & khawb kab noj hniav, ejector tus pin qhov, eroded rooj vag thiab khiav.
