1. Tswj pwm tsim
1. Ua ntej ntawm tag nrho cov, peb yuav tsum to taub tag nrho cov pwm qauv, cov khoom, hardness, precision thiab lwm yam kev xav tau ntawm cov neeg siv, xws li seb lub shrinkage npaum li cas ntawm cov khoom yas tsim yog lawm, seb cov khoom 3D loj yog ua tiav, thiab coj tsim nyog. kev soj ntsuam.
2. Ua tib zoo xav txog qhov chaw uas cuam tshuam rau qhov pom ntawm cov khoom siv tshuaj molding, xws li shrinkage kab noj hniav, ndlwg cim, lub kaum sab xis, vuam kab thiab tawg.
3. Simplify cov txheej txheem ntawm cov pwm kom ntau li ntau tau yam tsis muaj kev cuam tshuam cov khoom muaj nuj nqi thiab cov qauv zoo ntawm cov tshuaj molded ib feem.
4. Txawm hais tias qhov kev xaiv ntawm qhov chaw seem yog qhov tsim nyog, kev ua pwm, tsim cov tsos thiab deburring ntawm cov khoom tsim yuav tsum tau ua tib zoo xaiv.
5. Txawm hais tias txoj kev ejecting yog tsim nyog, seb lub laub pas nrig, stripping phaj, ejecting lub tes tsho los yog lwm txoj kev siv, thiab seb txoj hauj lwm ntawm lub thawb pas nrig thiab lub stripping phaj yog tsim nyog.
6. Txawm hais tias kev siv cov txheej txheem rub tawm sab nraud yog qhov tsim nyog, qhov kev txiav txim yog hloov tau thiab txhim khu kev qha, thiab yuav tsum tsis muaj stagnation.
7. Cov txheej txheem twg ntawm kev tswj qhov kub thiab txias yog qhov tsim nyog rau cov khoom siv yas, uas cov txheej txheem kev ua haujlwm yog siv rau kev tswj qhov kub thiab txias, tswj dej kub, coolant, thiab lwm yam, thiab seb qhov luaj li cas, qhov ntau, thiab qhov chaw ntawm qhov coolant qhov tsim nyog.
8. Daim ntawv ntawm lub rooj vag, qhov loj ntawm cov khoom siv channel thiab qhov chaw nres nkoj pub, thiab seb qhov chaw thiab qhov loj ntawm lub rooj vag puas tsim nyog.
9. Kev cuam tshuam ntawm kev kho cua sov deformation ntawm ntau yam modules thiab pwm cores thiab seb qhov kev xaiv ntawm cov qauv yog tsim nyog.
10. Seb lub ntim ntim, kev txhaj tshuaj siab thiab clamping quab yuam ntawm lub tshuab txhaj tshuaj molding yog txaus, seb lub nozzle R, lub qhov taub ntawm lub tes tsho sprue, thiab lwm yam.
Kev tsom xam thiab kev npaj ntawm cov khoom no yuav tsum nruj me ntsis tswj los ntawm thawj theem ntawm cov khoom.

Thib ob, kev tswj cov txheej txheem tsim khoom
Txawm hais tias peb tau txiav txim siab tag nrho thiab npaj rau theem tsim, tseem yuav muaj ntau yam teeb meem thiab teeb meem hauv kev tsim khoom tiag tiag. Peb yuav tsum sim peb qhov zoo tshaj plaws kom ua tau raws li lub hom phiaj tseem ceeb ntawm kev tsim khoom hauv kev tsim khoom, thiab nrhiav kev ua haujlwm zoo, kev lag luam ntau dua thiab tsim nyog hauv kev ua haujlwm tiag tiag. txheej txheem txhais tau tias.
1. Xaiv cov cuab yeej siv hluav taws xob thiab hloov tau yooj yim rau 2D thiab 3D kev daws teeb meem.
2. Cov cuab yeej tsim nyog thiab cov khoom siv kuj tseem tuaj yeem txiav txim siab rau kev npaj cov khoom siv hauv kev tsim khoom, thiab kev siv cov cuab yeej tsim nyog tuaj yeem tiv thaiv cov khoom seem los ntawm kev deformed, tiv thaiv cov khoom seem los ntawm qhov hloov pauv ntawm qhov shrinkage, tiv thaiv cov khoom seem los ntawm kev demolded thiab deformed, txhim kho. lub precision ntawm pwm manufacturing, txo me me yuam kev, tiv thaiv kev hloov ntawm pwm precision, thiab lwm yam., ib tug series ntawm ntau lawm txheej txheem yuav tsum tau thiab cov kev daws teeb meem.
3. Ntawm no yog cov laj thawj ntawm qhov yuam kev ntawm qhov tsim ntawm British Plastics Association (BPF) thiab kev faib tawm ntawm qhov kev faib ua feem:
A: Qhov yuam kev tsim pwm yog li 1/3, B qhov yuam kev tshwm sim los ntawm pwm hnav yog 1/6C qhov yuam kev tshwm sim los ntawm qhov tsis sib xws ntawm qhov qis ntawm qhov tsim yog li 1/3, thiab qhov yuam kev tshwm sim los ntawm qhov tsis sib xws ntawm predetermined shrinkage tus nqi thiab qhov tseeb shrinkage tus nqi yog hais txog 1/3 1/6
tus
Qhov yuam kev tag nrho=A ntxiv rau B ntxiv rau C ntxiv rau D, yog li nws tuaj yeem pom tias kev tsim cov pwm pwm yuav tsum tsawg dua 1/3 ntawm qhov ntev ntev ntawm qhov tsim, txwv tsis pub nws yuav nyuaj rau cov pwm los lav qhov loj geometric ntawm qhov tsim.
3. Feem ntau tswj kev tsim khoom
Kev hloov pauv hauv qhov ntev geometric tom qab cov khoom yas tau tsim yog ib qho teeb meem tshwm sim, thiab nws yog qhov tshwm sim uas feem ntau tshwm sim:
1. Kev tswj cov khoom kub thiab pwm kub. Cov khoom sib txawv ntawm cov yas yuav tsum muaj qhov ntsuas kub sib txawv. Cov ntaub ntawv yas nrog cov dej tsis zoo thiab kev siv ntau tshaj ob hom kev sib tov yuav muaj qhov sib txawv. Cov ntaub ntawv yas yuav tsum tau tswj ntawm qhov zoo tshaj plaws ntws Cov no feem ntau yooj yim ua nyob rau hauv tus nqi ntau, tab sis kev tswj pwm kub yog qhov nyuaj dua. Cov duab geometric sib txawv, qhov ntau thiab tsawg, thiab phab ntsa thickness sib txawv ntawm qhov sib txawv tsim muaj qee qhov kev xav tau rau cov tshuab cua txias. Cov pwm kub yog qhov loj Tswj lub sijhawm txias;
Yog li ntawd, sim ua kom cov pwm ntawm qhov tso cai qis qis kom luv lub voj voog txhaj tshuaj thiab txhim kho kev tsim khoom. Yog hais tias pwm kub hloov, tus nqi shrinkage kuj yuav hloov, pwm kub yuav nyob ruaj khov, thiab qhov tseeb qhov seem yuav ruaj khov. Cov teeb meem xws li deformation, gloss tsis zoo, thiab qhov chaw txias ua rau lub cev muaj zog ntawm cov yas hauv lub xeev zoo tshaj plaws. Ntawm chav kawm, muaj cov txheej txheem debugging, tshwj xeeb tshaj yog cov kab noj hniav molded feem ntau nyuaj. Yog li ntawd, cov pwm kub tsis tuaj yeem hloov pauv arbitrarily thaum lub sij hawm ntau lawm txheej txheem, thiab qhov chaw ntawm pwm kub yuav tsum nyob rau hauv lub pom zoo kub ntau yam ntawm cov khoom.
2. Kev hloov kho thiab tswj lub siab thiab tso pa tawm:
Kev txhaj tshuaj siab yog qhov tsim nyog thiab qhov sib txuam ntawm lub zog clamping yuav tsum tau txiav txim siab thaum lub pwm yog debugged. Cov cua hauv qhov sib txawv uas tsim los ntawm cov pwm kab noj hniav thiab cov tub ntxhais thiab cov roj uas tsim los ntawm cov yas yuav tsum tau tawm ntawm cov pwm los ntawm qhov tso pa tawm, xws li tso pa tawm yog tias huab cua tsis du, yuav muaj qhov txhaws tsis txaus, ua rau cov khoom siv vuam. cov cim los yog kub hnyiab; daim duab
Peb qhov kev ua tsis zoo no qee zaum tshwm sim nyob rau tib lub sijhawm. Thaum muaj cov phab ntsa tuab nyob ib ncig ntawm cov phab ntsa nyias nyias ntawm qhov tsim, cov cim shrinkage yuav tshwm sim thaum pwm kub qis dhau, thiab kub hnyiab yuav tshwm sim thaum pwm kub siab dhau. Feem ntau yuav muaj cov cim vuam ntawm qhov chaw hlawv tib lub sijhawm, thiab cov grooves feem ntau tsis quav ntsej, thiab feem ntau nyob rau hauv lub xeev me me, yog li feem ntau, tsuav yog tsis muaj burrs raug tsim; Cov qhov cua loj dua, kom cov pa uas dhau los ntawm lub xub pwg tuaj yeem tawm sai sai ntawm cov pwm. Yog tias muaj qhov xav tau tshwj xeeb, lub qhov tso tawm yuav tsum qhib rau ntawm tus pin ejector. Qhov laj thawj yog tib yam. Ua ntej, tsis muaj flash, thiab qhov thib ob, huab cua tso tawm Ntev npaum li nws ua haujlwm zoo, nws yuav ua.
Qhov tob ntawm lub xub pwg nyom yuav tsum sib sib zog nqus li sai tau, thiab lub qhov cua loj loj yog muab rau tom qab ntawm lub xub pwg kom cov roj uas hla lub xub pwg tuaj yeem tawm sai sai ntawm cov pwm. Qhov laj thawj yog tib yam, ib qho yog tias tsis muaj flash, thiab lwm qhov yog tias huab cua tuaj yeem tso tawm sai sai thiab cov nyhuv tuaj yeem ua tiav zoo.
3. Supplementary shaping tswj kev txhaj tshuaj molded qhov loj me
Vim tias qhov sib txawv ntawm cov duab thiab qhov loj ntawm qee qhov yas, deformation thiab warping yuav tshwm sim nyob rau hauv ntau qhov sib txawv nrog rau kev hloov ntawm kub thiab siab poob tom qab demoulding. Lub sijhawm no, qee qhov kev pabcuam pabcuam tuaj yeem hloov kho kom sai thiab nrawm Siv cov kev ntsuas kho, thiab tom qab nws tau txias thiab zoo li qub, kev kho kom zoo dua qub tuaj yeem tau txais. Yog tias kev tswj hwm nruj tau ua kom ntseeg tau thoob plaws hauv cov txheej txheem txhaj tshuaj molding, qhov loj ntawm qhov txhaj tshuaj molded qhov chaw yuav raug tswj kom zoo.
