Cov pwm uas ploj lawm, tseem hu ua cov pwm dawb, yog cov pwm siv los ua cov pwm castings.Lub plam ua npuas ncauj pwm yog tau los ntawm casting ua npuas ncauj hlaws tom qab kho thiab foaming.Thaum cov pwm tsim, nws tseem yuav raug puas tsuaj rau qee yam, xws li ua npuas ncauj ploj.Tom qab cov pwm tsim, nws pom tias muaj cov khoom tsis txaus, yog vim li cas rau qhov tshwm sim no?

1. Cov hlaws tsis zoo ua ntej kev txhim kho

Nyob rau hauv ib txwm muaj xwm txheej, thaum huab cua siab tas li, lub peev xwm ntawm cov hlaws ua ntej nthuav dav txo qis nrog lub sijhawm ntev ntawm lub qhov cua, thiab qhov ceev ntawm cov hlaws ua ntej nthuav dav txo nrog qhov nce ntawm lub vapor siab thaum lub sij hawm tso pa tawm. tsis hloov.Ua ntej pre-blasting, yog hais tias cov hlaws dai tsis tau soj ntsuam tag nrho, cov ntxhib thiab nplua particle loj yog tsis sib xws, los yog lub stirring ceev ceev heev, cov hlaws dai yog rhuab tsis sib npaug, uas yuav ua rau tsis txaus pre-blasting thiab tsis sib xws ntawm cov hlaws dai. .Qhov no yuav ua rau qhov tshwm sim ntawm molding khoom tsis txaus.

2. Cov nyhuv ripening tsis zoo

Yog vim li cas rau qhov tsis zoo ripening nyhuv tej zaum yuav yog hais tias lub chav siab mov yog tsis txaus.Txhawm rau kom yooj yim rau kev sib txuas ntawm cov txheej txheem molding, cov hlaws xa tuaj ua ntej yuav tsum tau ripened.Yog li ntawd, cov nyhuv ntawm ripening yog zoo heev, uas yog ze ze rau qhov tsis muaj cov khoom.

3. Cov khoom siv tsis txaus

Thaum cov pwm tsim, cov khoom siv tsis txaus yog feem ntau yog vim "bridging" tshwm sim ntawm qhov chaw noj mov, uas yuav ua rau cov khoom siv tsis txaus, uas ua rau muaj qhov tshwm sim ntawm molding tsis txaus.

4. Pwm tsis zoo

Xyuas seb puas muaj cov kab mob khaub thuas, lossis seb txoj haujlwm puas yog.Rau cov pwm nrog lub qhov tob tob, lub qhov tso pa tawm thiab lub qhov tso tawm yuav tsum tau ntxiv rau ntawm qhov qis qis, thiab qhov tsim nyog qhov chaw tso tawm tuaj yeem qhib rau ntawm qhov chaw clamping.Lub qhov tso pa yuav tsum tau teem rau ntawm qhov kawg filling ntawm kab noj hniav.Yog tias qhov chaw nres nkoj tso tawm tsis tsim nyog, nws yuav ua rau lub filling yuav luv ntawm cov khoom.
