Pwm yog lub hauv paus tseem ceeb rau kev ua kom qhov tseeb ntawm txhuas tuag castings. Thaum lub sij hawm tsim pwm, cov kab noj hniav qhov ntev, phab ntsa thickness faib, thiab demolding txoj kev yuav tsum tau rationally npaj raws li cov yam ntxwv ntawm cov khoom kom tsis txhob deformation los ntawm kev nyuaj siab concentration los yog tsis tsim nyog qauv.
Thaum lub sij hawm ua pwm, kev tswj nruj ntawm kev ua haujlwm raug thiab kab noj hniav zoo yog tsim nyog. Nyob rau tib lub sijhawm, lub qhov dej- tsim cov qauv cua txias yog qhov tseem ceeb los tswj pwm kev ruaj ntseg thaum lub sijhawm tsim khoom, yog li txhim kho qhov ruaj khov thiab qhov sib xws ntawm txhuas tuag castings.
Cov txheej txheem kev khiav hauj lwm ntawm cov cuab yeej cuam tshuam ncaj qha rau kev tsim cov txhuas tuag castings. Kev saib xyuas tsis tu ncua thiab calibration ntawm cov khoom siv tuag casting, ua kom lub zog ruaj khov ntawm lub clamping system, kev txhaj tshuaj, thiab kev tswj qhov system, pab txo qhov kev hloov pauv thaum lub sijhawm tsim khoom. Cov cuab yeej ruaj khov precision yog qhov tseem ceeb lav rau kev txhim kho qhov tseeb qhov tseeb thiab qhov zoo ntawm txhuas tuag castings.
