Thaum tsim cov khoom yas rau ntau lawm, tsim pwm yog ib feem tseem ceeb ntawm cov txheej txheem. Cov pwm yog cov cuab yeej siv los tsim cov khoom kawg, yog li nws yog ib qho tseem ceeb los xyuas kom meej tias cov pwm tsim nrog precision thiab raug. Qhov no yog qhov tseem ceeb ntawm daim duab kos duab los ntawm cov yas.
1. Qhov ntev
Qhov tseem ceeb tshaj plaws ntawm kev kos duab yas yog qhov ntev. Cov qhov ntev no txhais qhov loj thiab cov duab ntawm cov khoom kawg. Nws yog ib qho tseem ceeb uas cov no yog qhov tseeb raws li qhov ua tau, vim qhov txawv ntawm qhov ntev tuaj yeem ua rau muaj qhov tsis xws luag hauv cov khoom kawg.
2. Phab ntsa Thickness
Nws hais txog lub thickness ntawm cov khoom yas nyob rau hauv ntau qhov chaw ntawm cov khoom. Cov phab ntsa tsis sib xws tuaj yeem ua rau warping lossis sagging nyob rau hauv cov khoom kawg, yog li nws yog ib qho tseem ceeb kom ua tib zoo txheeb xyuas cov phab ntsa thickness nyob rau hauv ntau qhov chaw.
3. Qhov chaw ntawm lub rooj vag
Lub rooj vag yog qhov chaw uas cov khoom siv yas molten nkag mus rau hauv pwm thaum lub sijhawm txhaj tshuaj. Qhov chaw thiab qhov luaj li cas ntawm lub rooj vag ua lub luag haujlwm tseem ceeb hauv kev ua kom cov khoom yas ntim cov pwm tag nrho thiab sib npaug. Nws yog ib qho tseem ceeb uas yuav tau txiav txim siab txog yam xws li rooj vag loj, qhov chaw, thiab kev taw qhia thaum tsim cov khoom siv yas kos duab.
4. Ejector Pin Qhov chaw
Ejector pins yog siv los tshem tawm cov yas ntawm pwm thaum nws tau tsim. Nws yog ib qho tseem ceeb uas yuav tau xav txog qhov chaw thiab kev taw qhia ntawm cov pins no, nrog rau cov duab thiab qhov tob ntawm ejector tus pin nyem, kom ntseeg tau tias lawv tsis tawm cov cim lossis kev puas tsuaj ntawm cov khoom kawg.
5. Draft Angle
Draft lub kaum sab xis hais txog lub kaum sab xis ntawm ob sab ntawm cov yas thiab ua lub luag haujlwm tseem ceeb hauv cov txheej txheem pwm tso tawm. Yog tsis muaj lub kaum sab xis tsim nyog, cov khoom yas yuav lo rau hauv pwm los yog nyuaj rau tshem tawm. Lub kaum sab xis yuav tsum tau tsim los xyuas kom meej tias cov yas yuav yooj yim tso tawm ntawm pwm.
6. Nto tiav
Ib qho kev nthuav dav uas qhia txog qhov haum rau lwm yam khoom;
Engraving, artwork thiab kab noj hniav;
Pwm daim ntawv lo (yog tias muaj nyob rau hauv pwm);
Txhua yam ntaub ntawv stacking (yog tias tsim nyog);
Qhov hnyav (siv qhov xav tau ntawm cov yas ntom ntom);
Ib feem ntim (yog tias ntim thiab hnyav);
Center ntawm lub ntiajteb txawj nqus (yog tias tsim nyog);
Kev txheeb xyuas ntawm cov yas lossis steel qhov loj me;
Txheeb xyuas tag nrho cov kab sib cais thiab cov kab sib cais, suav nrog txhua qhov kev xav tsis sib haum.
Thaum daim duab kos tiav lawm, nws yuav tsum tau tshuaj xyuas nrog tus neeg siv khoom thiab sab hauv ntawm lub tshuab moldmaker qhov chaw. Tom qab kuaj xyuas tag nrho cov khoom saum toj no, cov neeg tsim khoom tuaj yeem xyuas kom meej tias cov khoom kawg yog tsim kom raug thiab ua tau zoo.
