Moulds yog cov cuab yeej tseem ceeb hauv kev tsim khoom, thiab lawv cov qauv tsim ncaj qha cuam tshuam rau cov duab, qhov tseeb, thiab qhov zoo ntawm qhov chaw. Pwm tsim yuav tsum tau xav txog tag nrho cov yam ntxwv ntawm cov khoom, casting txheej txheem yuav tsum tau, thiab manufacturing nyuaj thiab tus nqi ntawm cov pwm. Thaum lub sij hawm tsim cov txheej txheem, cov khoom tseem ceeb xws li qhov chaw sib cais, qhov rooj kaw lus, thiab lub qhov cua yuav tsum tau txiav txim siab los xyuas kom meej tias cov hlau molten tuaj yeem ntws mus rau hauv pwm thiab sau tag nrho cov kab noj hniav.
Kev tsim pwm yog qhov tseem ceeb sib npaug. High-kev tsim pwm precision ua kom qhov tseeb qhov tseeb thiab qhov zoo ntawm qhov chaw. Thaum lub sijhawm tsim khoom, cov cuab yeej ua haujlwm siab heev thiab cov txheej txheem, xws li CNC machining thiab EDM, yuav tsum tau ua haujlwm los txhim kho qhov raug thiab ua haujlwm ntawm pwm. Ib txhij, cov pwm yuav tsum tau soj ntsuam nruj thiab debugging kom ntseeg tau tias nws ua tau raws li cov qauv tsim.
