1. Qee tus molds tsim tau ob peb txhiab ntawm cov suab thaj tawg, thiab tawg sai sai sai.Yog tau txais kev pom zoo qhov loj me me, tsuas yog thaum forging thiab steel ntawm dendritic siv lead ua, mixed carbide, xoob xws li shrinkage kab noj hniav , npuas ncav raws li cov kev ua haujlwm txuas ntxiv, kev xaav, qhov kev xaus kev quenching kawg distortion thiab tawg nyob rau hauv lub neej yav tom ntej, nyob rau hauv tus txheej txheem ntawm kev siv ntawm cov nyhuv tau muaj kev cuam tshuam rau cov kev xav.
2. Lub siab ntxhov tshwm sim tshwm sim thaum lub sijhawm kawg ntawm cov tsheb, kev sib tsoo thiab kev npaj, uas yuav raug tshem tawm los ntawm qhov chaw tua tsiaj.
3. Qhov kev ntxhov siab sib tsoo tshwm sim thaum lub qhov sib zog tawv yog sib tsoo, thiab kev sib sib zog nqus cua kub thaum lub sib tsoo. Cov txheej txheem softening txheej txheem thiab decarburization txheej tshwm sim, uas txo lub zog ntawm lub tshav kub, uas yooj yim ua rau kub tawg thiab tawg thaum tawg.Tus H13 hlau tom qab nplua nplua, tolerated rhaub mus rau 510-570 ℃, ib teev rau 25 hli rwb thaiv kom tuab tshem tawm kev nyuaj siab kev nyuaj siab.
4. Kev nyuab ntawm hluav taws xob paug ua haujlwm.Qhov ntim ntawm lub pwm muaj ib txheej ntawm cov khoom siv hlau electrode thiab dielectric lub cev dawb ci txheej, tawv thiab nkig, qhov txheej txheem no nws yuav muaj kab nrib, muaj kev ntxhov siab.Qhov siab yuav tsum tau siv nyob rau hauv hluav taws xob paug ua haujlwm kom txo cov txheej txhuam hniav. Txoj kev polishing txoj kev yuav tsum tau muab tshem tawm thiab kev kho cov tshuaj tiv thaiv yog nqa tawm, thiab qhov kub hnyiab yog ntsuas ntawm peb theem kub kub.
