Tsiaj Txhaj Tshuaj Molding

PET (Polyethylene Terephthalate) yas txhaj tshuaj molding muaj zog, hnav, thiab khoom noj khoom haus-cov khoom muaj kev nyab xeeb nrog kev pom meej zoo, dav siv hauv ntim khoom, cov khoom siv, thiab cov khoom siv tsheb.

Polyethylene terephthalate (PET) tseem hu ua polyester. Lub rheology ntawm lub xeev molten PET yog qhov zoo heev, thaum lub siab muaj kev cuam tshuam ntau dua rau nws cov viscosity tshaj qhov kub thiab txias. Yog li ntawd, tus qub yog feem ntau leveraged los hloov lub fluidity ntawm PET yaj.
Nws yog cov khoom ntim zoo heev, tso cai rau kev tsim muaj tswv yim zoo heev thaum cov kws tshaj lij txhaj tshuaj.

PET yog rhiab heev rau cov dej noo ntawm qhov kub thiab txias thiab nthuav tawm ntau warpage thaum ntxiv nrog iav fibers. Kev txhawb nqa ntawm crystallinity yog ua tiav los ntawm kev ntxiv cov tshuaj nucleating thiab siv lead ua accelerators. Crystalline moldings nthuav tawm siab modulus, gloss, thiab kub distortion kub. Warpage yog txo qis los ntawm kev sib ntxiv ntawm particulate fillers xws li mica. Thaum siv cov pwm kub qis, pob tshab moldings.

Kauj Ruam 1: Resin Preparation
Polyethylene Terephthalate (PET) resin yuav tsum tau ua kom huv si ua ntej- ziab ua ntej molding kom tshem tawm cov dej noo. PET yog hygroscopic heev, thiab cov dej seem seem tuaj yeem ua rau hydrolytic degradation, ua rau cov saw hlau tsis muaj zog thiab ua rau cov khoom tawg lossis puas. Kev ziab yog feem ntau ua tiav ntawm 160℃txog 180℃rau 4 mus rau 6 teev, siv lub tshuab dehumidifying lossis desiccant system.

Kauj Ruam 2: Melting thiab Txhaj Tshuaj
Tom qab ziab, PET resin yog pub rau hauv lub thoob ntawm lub tshuab txhaj tshuaj molding. Lub thoob yog rhuab mus rau qhov kub ntawm 250℃thiab 280 degree, nyob ntawm seb cov qib tshwj xeeb ntawm PET thiab ib feem tsim. Ntawm qhov kub no, cov resin yaj thiab tom qab ntawd txhaj rau hauv qhov siab siab -feem ntau ntawm 10,000 txog 30,000 psi- rau hauv cov pwm kab noj hniav. Qhov kev kub siab no ua kom tiav cov pwm ua tiav, tshwj xeeb tshaj yog nyob rau hauv qhov chaw nrog cov geometry nyuaj lossis cov phab ntsa nyias.

Kauj Ruam 3: Txias thiab Solidification

Thaum lub molten PET puv cov pwm, nws yuav tsum txias thiab khov kho raws li kev tswj hwm. Kev ua kom txias yog feem ntau ua tiav los ntawm dej- cov kab pwm txias txias, tswj kom tsis txhob muaj qhov kub thiab txias kom tsis txhob muaj cua sov, shrinkage, lossis kev ntxhov siab sab hauv. Lub sij hawm txias nws txawv nyob ntawm qhov tuab thiab qhov loj ntawm qhov molded tab sis yog ib kauj ruam tseem ceeb hauv kev ua tiav qhov tseeb qhov tseeb thiab lub zog txhua yam.

Kauj Ruam 4: Tshem tawm thiab Tshaj Tawm -Kev ua tiav

Tom qab solidification, pwm qhib, thiab ib feem yog ejected siv ib tug ejection system (ejector pins, tes tsho, los yog daim hlau). Ib feem yog npaj txhij rau kev tshaj tawm - ua tiav, uas yuav suav nrog:

Trimming tshaj flash

Polishing los yog nto tiav

Txheej lossis luam ntawv yog tias xav tau

Thaum kawg, ib feem tau txais kev tswj xyuas zoo kom ntseeg tau tias nws ua tau raws li tag nrho cov qauv, txhua yam, thiab kev zoo nkauj.
