High Quality Multi Color Txhaj Tshuaj OVERMOLDED Cov Khoom Uas Yas
Overmolding tseem hu ua 2 zaugtxhaj tshuaj molding hauv Suav tebCov. Piv nrog rau cov khoom siv thib peb cov khoom sib txuas, cov txheej txheem overmolding ua rau cov txheej txheem sai dua thiab raug nqi, nws tau ua haujlwm dav hauv cov qauv yas.
Tshaj molding yog cais rau hauv 3 hom: ntxig molding, ob chav txhaj moulding, co-molding.
Ntxig molding: Qhov feem ntau siv los ua pwm mos elastomers kom txhav plastics, ntxig molding yog qhov kev lag luam uas yooj yim tshaj plaws los ua overmolding. Hauv kev teeb tsa ntxig, qhov nyuaj ntu tau muab cais ua cov cuab yeej ua ntej, thiab tom qab ntawd eject cov khoom mos hauv.
Elastomers yog adhesion daim ntawv cog lus, uas tuaj yeem siv tshuab xauv, tshuaj lom neeg thiab lwm txoj kev. Txhawm rau kom ua tiav cov tshuaj pleev ib ce, cov elastomer yuav tsum tau muaj cua sov txaus kom yaj ntawm qhov ntu ntawm cov ntu nyuaj kom ua tiav cov tshuaj sib txuas.
Ob-tshuab moulding: Qhov no dhau molding txheej txheem xav tau ob leeg txhaj tshuaj molding tshuab. Cov ntu nyuaj yog txhaj ua ntej, thiab tom qab ntawd coj los ntawm elastomeric pwm mus rau kev txhaj tshuaj molding tshuab, tiav cov txheej txheem ntawm cov ntu nyuaj rau hauv kev txhaj tshuaj elastomer. Thaum tshav kub kub substrate feem ntau yog semi-solid, gel xeev. Cov nopuabtuaj yeem tsim thiab txua qhov projecting tom qab ntawm ntu ntu rau ntawm cov substrate. Qhov no tuaj yeem ua tiav qhov kev ruaj khov rau kev siv tshuab.
Co-txhaj tshuaj molding: Hauv kev sib xyaw moulding, thaum lub substrate nyuaj thiab elastomer yog txhaj rau hauv tib lub pwm, qhov sib txawv ntawm cov khoom siv yog qhov tseem ceeb, nws yuav tsum tau ua tib zoo tswj.
Co-Txhaj Tshuaj yog kim heev thiab nyuaj rau kev tswj hwm; nws yog siv tsawg kawg muab piv nrog lwm 2 qauv. Txawm li cas los xij, vim hais tias qhov nyuaj thiab mos substrates elastomers nyob rau hauv lub xeev siab yaj, nws muab txoj kev sib koom tes zoo tshaj plaws ntawm qhov muag thiab tawv, qhov chaw ntawm cov pwm no kuj yog qhov zoo tshaj plaws.
