Thawj qhov yuav tsum tau saib yog cov khoom siv rau lub pwm. Ntau tus neeg muas zaub paub tias lawv yuav tsum txiav txim siab cov khoom siv rau lub pwm nrog cov chaw tsim khoom ua ntej tso pwm. Qhov kev xaiv ntawm steel yog qhov kev xaiv ntawm steel hardness thiab toughness. Rau lub pwm, qhov ntau dua qhov nyuaj ntawm qhov xaiv hlau, qhov nyuaj nws yuav tsum hnav thaum lub sijhawm txheej txheem ntau lawm, thiab kev pab cuam lub neej ntev dua. Kev pab cuam lub neej ntev dua txhais tau tias cov pwm tuaj yeem tsim cov khoom lag luam ntau dua, uas yog ib qho kev txuag nyiaj rau cov chaw lag luam yas.
Qhov thib ob, nws nyob ntawm seb pwm puas yooj yim puas nyob rau hauv kev tsim khoom thiab txij nkawm, thiab feem ntau yuav tsum tau kho.
Tsis tas li ntawd, saib cov khoom lag luam tsim rau burrs, burrs, thiab thaj chaw du. Muaj cov burrs, burrs, thiab tsis du yog twv yuav raug hu tsis tau zoo, kev txhaj tshuaj molding cov neeg lag luam yuav tsum npaj rau cov neeg muaj kev cuam tshuam nrog burrs thiab burrs, uas yog lub sijhawm pov tseg, khib nyiab ntawm tus txiv neej thiab cov peev txheej.
Tsis tas li ntawd, saib seb muaj pes tsawg lub pwm tuaj yeem tsim hauv ib pliag, uas yog, nws siv sijhawm ntev npaum li cas los ua pwm pwm, uas tseem xam tau tias tus nqi tsim khoom ntawm lub tuam txhab txhaj tshuaj moulding. Yog tias pwm qhib kev nrawm dua, tom qab ntawd cov khoom lag luam tsim nyob rau hauv ib lub sijhawm tshwj xeeb Ntau yam, tuaj yeem txuag cov nqi ntau lawm ntawm kev txhaj tshuaj molding manufacturers.
