Cov khoom siv xaiv thiab sib txuam
Kev vam meej ntawm TPE overmolding ob- xim txhaj tshuaj molding feem ntau nyob ntawm kev xaiv thiab sib txuam ntawm cov ntaub ntawv. Thaum xaiv cov ntaub ntawv TPE, yam xws li hardness, elasticity, hnav tsis kam, kev laus tsis kam, thiab kev sib raug zoo nrog cov yas tawv yuav tsum raug txiav txim siab. Nyob rau tib lub sijhawm, kev xaiv cov yas nruj yuav tsum xav txog yam xws li lub zog, kev nruj, kev ua haujlwm, thiab kev sib koom ua ke nrog TPE.
Pwm Tsim thiab tsim khoom
Pwm tsim thiab kev tsim khoom yog qhov tseem ceeb ntawm TPE overmolding ob -xim txhaj tshuaj molding. Pwm tsim yuav tsum xav txog cov khoom tsim, qhov ntev, cov duab, thiab kev txhaj tshuaj molding txheej txheem, kom ntseeg tau tias cov pwm kab noj hniav raug, demolding qauv, thiab qhov rooj qhov chaw ua tau raws li cov kev xav tau ntau lawm. Tsis tas li ntawd, kev tsim khoom zoo ntawm cov pwm ncaj qha cuam tshuam rau cov khoom molding zoo thiab ntau lawm efficiency.
Txhaj Molding Txheej Txheem Tswj
Kev txhaj tshuaj molding txheej txheem tswj yog ib qho ntawm cov thev naus laus zis tseem ceeb hauv TPE overmolding ob -xim txhaj tshuaj molding. Thaum lub sij hawm txhaj tshuaj, tsis xws li kev txhaj tshuaj kub, txhaj tshuaj siab, txhaj tshuaj ceev, thiab tuav lub sij hawm yuav tsum tau nruj me ntsis tswj kom ntseeg tau tias ob cov ntaub ntawv muaj peev xwm tag nrho daim ntawv cog lus thiab tsim ib tug unified khoom. Ib txhij, yuav tsum tau them nyiaj rau cov txheej txheem preheating thiab txias ntawm pwm kom tsis txhob muaj qhov tsis xws luag xws li cov khoom deformation lossis shrinkage.
Chemical Bonding thiab Physical Locking: Ob txoj hauv kev tuaj yeem siv los ua kom muaj kev sib raug zoo ntawm TPE thiab cov yas tsis muaj zog: kev sib txuas tshuaj lom neeg thiab lub cev locking. Cov tshuaj sib txuas nruj nreem khi ob cov ntaub ntawv ua ke los ntawm kev sib xyaw ua ke, kev nkag mus, thiab molecular entanglement. Kev ntsuas lub cev, ntawm qhov tod tes, siv cov qauv tshwj xeeb (xws li snap- haum lossis xov) txhawm rau txhawm rau ntsuas ob yam khoom ua ke. Hauv kev siv tswv yim, ob txoj hauv kev no feem ntau siv ua ke kom tau txais txiaj ntsig zoo dua.
