Ib, Yuav ua li cas molded pulp pwm ua haujlwm
Muab cov ntaub ntawv pov tseg nrog dej los ua ib lub pulp
Siv cov pwm los ntub cov fibers hauv lub tshuab nqus tsev
Daim ntawv ntub dej uas tau ua ntej - tsim
Cov khoom kawg yog ua tom qab nws tau compressed thiab qhuav.
Thaum lub sij hawm cov txheej txheem no, cov pwm tsis tsuas yog tsim cov khoom, tab sis nws kuj muaj kev cuam tshuam ncaj qha rau:
Lub zog ntawm cov qauv thiab uniformity ntawm molding
Qhov zoo ntawm qhov chaw thiab efficiency ntawm ntau lawm
ob ️⃣ Kev tsim tshwj xeeb xav tau rau ntim khoom siv hauv tsev
Cov khoom siv hauv tsev yog qhov nyuaj, yog li lawv cov khoom ntim yuav tsum zoo dua:
Irregular structures thiab nto nrog ob peb nkhaus, xws li cua fryers thiab teeb vaj tse
Cov ntsiab lus tsis muaj zog (screen, pob qhov rooj, thiab interface)
Cov qauv siab rau qhov zoo li (kos-resistant, siab-resistant)
Cov chav kawm hnyav sib txawv (los ntawm 0.5 kg txog 30 kg thiab ntau dua)
Yog li, kev tsim pwm yuav tsum ua raws li cov kev xav tau no:
👉 Cov txheej txheem yuav tsum tuaj yeem hloov mus rau cov qauv sib txawv, muab kev tiv thaiv buffering, thiab ua kom yooj yim.
peb 3 Peb lub hom phiaj tseem ceeb ntawm kev tsim pwm
Cov khoom tiv thaiv: absorbing cuam tshuam los ntawm cov qauv
Haum: Haum cov duab ntawm cov khoom zoo kawg nkaus
Txhawb Kev Tsim Khoom: Ua kom muaj kev tsim khoom ruaj khov thiab ua haujlwm tau zoo
2, Kev soj ntsuam cov khoom raws li cov qauv ntawm cov khoom siv hauv tsev
Pwm tsim yuav tsum ua raws li cov ntaub ntawv 3D, uas suav nrog cov ntaub ntawv tseem ceeb xws li
Qauv hauv STEP/IGES
Cov qauv rau kev muab cov khoom sib xyaw ua ke
Kev faib tawm ntawm qhov chaw ntawm lub ntiajteb txawj nqus
Kev ntsuam xyuas tseem ceeb:
Raised qauv (khawm, interface)
Cov chaw tsis muaj zog ( iav panels, ornamental parts)
Zone ntawm cov qauv muaj zog (qhov chaw rau kev txhawb nqa, plhaub)
ob txoj cai tsim rau cov ntsiab lus txhawb nqa
Lub ntsiab lus txhawb nqa yog qhov tseem ceeb tshaj plaws ntawm kev txheeb xyuas qhov kev tiv thaiv zoo li cas:
Yam tsawg kawg peb lub ntsiab lus ntawm kev txhawb nqa (kom ruaj khov)
Nyob deb ntawm qhov chaw tsis muaj zog
Ze rau cov chaw uas muaj cov qauv tsim muaj zog
Cov txheej txheem tsim uas siv ntau heev:
Kev tiv thaiv rau cov ces kaum
Cov qauv rau nqa los ntawm hauv qab
Enveloping tsau qauv peb Buffers qauv tsim (core technology) rau
Cov qauv ntawm molded pulp muab nws lub peev xwm buffering, tsis yog cov khoom nws tus kheej.
Qee cov qauv sib xws yog:
Ripple qauv (ntau saj zawg zog)
Cov qauv ntawm kev txhawb zog (kom nws muaj zog)
Hollow qauv (absorbing zog los ntawm kev cuam tshuam)
Cov cai tsim:
👉 Ua kom ntev txoj kev cuam tshuam thiab txo qis qhov cuam tshuam.
3, Qhov tseem ceeb ntawm kev tsim qauv tuag:
1. Sib faib kab tsim
Puas yog nws yooj yim tshem tawm cov pwm
Nws puas hloov cov khoom zoo li cas
Cov pwm nyuaj npaum li cas
Tsim tswv yim:
Muab qhov kev siv ntawm ib qho kev sib cais ua ntej
Nyob deb ntawm cov qauv uas yog upside down
Khaws cov kev taw qhia ntawm demolding tib yam . 2. Draft Angle
Thaum tsimmolded pulp, qhov demolding txoj kab nqes yog qhov tseem ceeb uas tsis tuaj yeem tsis quav ntsej:
Qhov zoo tshaj plaws yog 2℃txog 5 degree.
Cov kab noj hniav sib sib zog nqus: loj dua yog qhov zoo dua
Muaj nuj nqi:
Txhob pwm los ntawm kev sib khi
Ua kom muaj txiaj ntsig ntau dua
Peb: Tsim cov phab ntsa thickness thiab xyuas kom meej tias nws yog txawm. Xya
Lub thickness ntawm ib txwm yog:
2mm rau 5mm
Cov ntsiab lus xav txog thaum tsim:
Uniform thickness (kom qhuav tsis sib xws)
Lub zos thickening nyob rau hauv qhov chaw tseem ceeb
Tsis txhob cia nws tuab heev, uas yuav ua rau tawg los yog sluggish qhuav.
plaub ️⃣ Tsim cov dej ntws thiab qhov nqus dej
Cov pwm siv lub tshuab nqus tsev adsorption molding, yog li nws yuav tsum tau tsim:
Lub qhov rau lub tshuab nqus tsev Drainage channel
Yam tseem ceeb:
Aperture: Tsis txhob thaiv nws
Distribution: Txawm kev pab them nqi
Qhov ntom ntom: muaj qhov cuam tshuam ntawm cov khoom tuab npaum li cas
tsib ️⃣ Xaiv cov khoom pwm
Cov khoom siv feem ntau siv:
Aluminium mould: Ntau yam meej thiab zoo rau kev ua ntau yam hauv ib zaug
Pwm tooj liab: muaj zog heev thiab ntev - kav ntev
Resin pwm: zoo rau kev kuaj
Cov txheej txheem rau kev xaiv:
Qhov project Theem (Sampling vs. Mass Production) tus nqi peev nyiaj xav tau
4, Tsim kom hloov cov txheej txheem thiab optimizing loj ntau lawm:
1. Xaiv cov txheej txheem molding
Cov txheej txheem tseem ceeb yog
Wet Press: heev meej, du nto, thiab raug nqi ntau heev.
Dry Press raug nqi ntau dua
Qhov saum npoo tsis du heev.
Qhov tseeb yog qhov nruab nrab, thiab tus nqi shrinkage thiab qhov loj me yog ob qho tib si.
Thaum lub sij hawm ziab, lub pulp yuav me me:
Feem ntau, 1% mus rau 3%
Hauv kev tsim, koj yuav tsum:
Them rau qhov loj me ua ntej
Nyob deb ntawm cov ntu loj uas tsis sib xws. Peb: Nesting thiab Stacking Design. Rau:
Ua kom muaj kev thauj mus los thiab khaws cia kom zoo li sai tau:
Nestable (ua kom me me)
Yooj yim rau pawg, uas ua rau nws ruaj khov dua
Yuav tsim li cas:
Cov qauv uas yog slanted
Teeb tsa cov ntsiab lus convex
plaub ️⃣ Automated ntau lawm adaptation
Cov kev xav tau rau kev tsim khoom niaj hnub:
Neeg hlau nqa thiab tsis siv neeg kis tau tus mob
Tsim tswv yim:
yooj yim to taub cov qauv
Zoo sib xws thiab repeatable
Nyob deb ntawm cov buckles nyuaj
