Txhim kho cov moulding qhov tseeb ntawm cov pob tawb-hauv qab tshuab: lub luag haujlwm ntawm kev hloov kho cov khoom lag luam

Khoom Siv Raw Khoom Siv: Cov khoom siv tau, tso lub hauv paus rau qhov tseeb
Cov khoom siv raw khoom yog cov tseem ceeb ntawm lub xwmfab hauv qab tshuab, uas cuam tshuam ncaj qha cuam tshuam txog cov khoom siv raw thiab ruaj khov ntawm cov khoom siv roj. Txhawm rau txhim kho cov khoom siv pwm, qhov ruaj khov thiab muaj txiaj ntsig ntawm cov khoom siv raw yuav tsum yog ua kom ua ntej.
Nyob rau hauv raw khoom siv system, siab, kub thiab ntws yog peb tus yuam sij hloov kho. Los ntawm kev kho lub siab ntawm cov khoom siv raw, txhaws cov khoom siv raw hauv cov teeb meem pwm tuaj yeem tswj tau, yog li zam kev teeb meem xws li tsis muaj peev xwm los yog txeej. Nyob rau tib lub sijhawm, qhov ntsuas kub ntawm cov ntaub ntawv nyoos kuj muaj qhov cuam tshuam tseem ceeb ntawm kev ua cov pwm. Qhov tsim nyog qhov ntsuas kub tuaj yeem ua kom cov tshuaj thiab cov yas ntawm cov khoom siv raw thiab txo qhov kev pheej hmoo ntawm kev ntxhov siab thiab deformation thaum lub sij hawm moulding txheej txheem. Tsis tas li ntawd, cov kev cai ntawm kev ntws tuaj yeem ua kom cov kev faib tawm ntawm cov khoom noj raw thaum lub sijhawm moulding txheej txheem, tsis txhob muaj kev tsis txaus siab hauv zos lossis tsub zuj zus.
Moulding txheej txheem tsis: Kho kom meej, kev ua kom pom zoo moulding nyhuv
Moulding txheej txheem tsis yog qhov txuas tseem ceeb los txhim kho cov khoom siv ntawm square hauv qab cov thawv hauv qab. Cov kev ntsuas no suav nrog qhov ntsuas kub, qhov siab thiab nrawm ntawm lub tshuab moulding, uas cuam tshuam rau qhov loj me, cov khoom thiab cov khoom siv ntawm cov khoom.
Qhov kub yog ib qho tseem ceeb tshaj plaws hauv cov txheej txheem moulding. Los ntawm kev kho qhov kub ntawm lub tshuab moulding, cov txheej txheem melting thiab txheej txheem raw tuaj yeem tswj tau qhov tseeb ntawm qhov tseeb thiab cov khoom lag luam zoo nkauj. Kev kub dhau heev yuav ua rau cov khoom siv raw rau yaj ntau dhau, ua rau muaj Flash thiab Burrs; Tsawg dhau qhov kub tsawg yuav ua rau cov khoom siv raw kom tsis txhob salormation thiab shrinkage. Yog li ntawd, raws li cov yam ntxwv ntawm cov ntaub ntawv raw thiab cov kev xav tau ntawm cov khoom, raug kho kom haum qhov ntsuas kub ntawm lub tshuab moulding yog qhov tseem ceeb los txhim kho cov khoom moulding.

Ntxiv rau qhov kub, siab thiab nrawm kuj tseem yog qhov tseem ceeb cuam tshuam rau cov khoom siv pwm. Los ntawm kev kho lub siab ntawm lub tshuab moulding, cov txheej txheem sib xyaw thiab puv cov khoom siv raw hauv cov pwm tuaj yeem tswj tau kom muaj zog thiab cov khoom nruj ntawm cov khoom. Kev nrawm yuav cuam tshuam rau tus nqi kom txaus thiab sau lub sijhawm ntawm cov ntaub ntawv raw, zam kev ua kom pom kev tsis xws luag los ntawm txhaws nrawm nrawm lossis qeeb.

Cua Txias Zog: Kev Lom Zem Ceev, Txo Cov Txiaj Ntsig
Lub kaw lus txias yog lwm qhov tseem ceeb ntawm lub square hauv qab lub thawv ntim molding tshuab. Nws yog lub luag haujlwm rau kev txo qis qhov kub ntawm cov khoom tom qab cov txheej txheem molding ua tiav, kom nws tuaj yeem ua kom sai thiab tsau.

Qhov kub thiab ntws tus nqi ntawm lub kaw lus txias yog qhov tseem ceeb cuam tshuam rau cov nyhuv txias. Los ntawm kev kho qhov ntsuas kub ntawm lub kaw lus txias, lub sijhawm cua txias ntawm cov khoom lag luam tuaj yeem tswj tau, yog li tsis txhob deformation thiab shrinkage ntawm cov khoom vim kev kub ntxhov. Nyob rau tib lub sijhawm, cov kev ntsuas ntws kom muaj kev faib tawm ntawm cov pwm txias ntawm cov pwm thiab cov khoom lag luam, txhim kho qhov ua kom txias. Hauv kev ua haujlwm tiag tiag, qhov ntsuas kub thiab ntws tus nqi ntawm lub txias txias yuav tsum tau kho kom haum raws li qhov loj me, cov khoom siv ntawm cov khoom. Rau cov khoom lag luam uas muaj loj loj thiab ntau cov duab, nws yuav tsim nyog los txais yuav cov cheeb tsam txias kom ntseeg tau tias txhua qhov tuaj yeem txias thiab muaj kev sib cais.
