Dab tsi yog qhov txhaj tshuaj molding ob zaug?

 

Ob chav txhaj tshuaj molding, tseem hu ua ob-shot molding los yog 2K molding, yog ib qho kev txhaj tshuaj molding tshwj xeeb uas siv los tsim cov khoom nyuaj nrog ntau yam xim, cov ntaub ntawv, lossis cov khoom siv hauv ib qho kev ua haujlwm. Cov txheej txheem no yuav tsum tau txhaj ob cov ntaub ntawv sib txawv lossis xim rau hauv ib lub pwm kab noj hniav los tsim ib qho kev sib xyaw nrog cov yam ntxwv sib txawv.

 

Nov yog li cas cov txheej txheem txhaj tshuaj molding ob zaug ua haujlwm:

 

1. Pwm tsim: Thawj kauj ruam hauv kev txhaj tshuaj ob zaug yog tsim cov pwm kom haum rau ntau yam khoom lossis xim. Cov pwm muaj ob lossis ntau qhov kab noj hniav, txhua qhov sib haum mus rau ib qho chaw tshwj xeeb lossis qhov tshwj xeeb ntawm qhov kawg. Cov kab noj hniav yog tsim los tso cai rau kev tso npe thiab kev sib koom ua ke ntawm cov khoom sib txawv lossis xim.

 

2. Kev txhaj tshuaj thawj zaug: Hauv thawj txhaj tshuaj molding txheej txheem, thawj cov khoom siv los yog xim yog txhaj rau hauv pwm kab noj hniav los tsim lub hauv paus lossis substrate ntawm ib feem. Cov khoom siv no yuav yog cov khoom siv thermoplastic, xws li ABS, PC, lossis PP, nyob ntawm seb qhov yuav tsum tau ua.

 

3. Pwm kev sib hloov lossis txav: Tom qab txhaj tshuaj thawj zaug, cov pwm tuaj yeem tig los yog txav mus rau qhov chaw thib ob rau kev txhaj tshuaj thib ob. Qhov no tso cai rau kev sib raug zoo ntawm cov ntaub ntawv sib txawv lossis xim thiab ua kom ntseeg tau tias lawv tau sib xyaw ua ke.

 

4. Kev txhaj tshuaj thib ob: Hauv kev txhaj tshuaj thib ob ntawm kev txhaj tshuaj molding txheej txheem, cov khoom siv thib ob lossis xim yog txhaj rau hauv pwm kab noj hniav kom tsim cov yam ntxwv ntxiv lossis txheej txheej rau saum thawj txhaj tshuaj. Cov khoom no yuav yog cov khoom siv thermoplastic sib txawv lossis cov khoom siv sib xws, xws li TPE (thermoplastic elastomer) lossis TPU (thermoplastic polyurethane).

 

5. Kev ua kom txias thiab ejection: Thaum ob qho kev txhaj tshuaj tau txhaj, cov pwm yog txias kom khov cov ntaub ntawv thiab qhov sib xyaw ua ke yog ejected ntawm pwm kab noj hniav. Tom qab ntawd, qhov yuav tsum tau ua tiav cov txheej txheem ntxiv, xws li trimming, deburring, lossis sib dhos, raws li xav tau.

 

Muab ob npaug rau txhaj tshuaj molding muaj ntau qhov zoo dua li cov txheej txheem molding, suav nrog:

 

- Txo cov sij hawm sib dhos thiab cov nqi: Los ntawm kev sib koom ua ke ntau yam khoom lossis cov yam ntxwv rau hauv ib feem, ob chav txhaj tshuaj molding tuaj yeem tshem tawm qhov xav tau ntawm kev ua haujlwm sib dhos, txo cov nqi zog thiab lub sijhawm sib dhos.

 

- Txhim kho ib feem ua haujlwm: Ob chav txhaj tshuaj molding tso cai rau kev sib koom ua ke ntawm cov khoom sib txawv nrog cov khoom sib txuas, xws li cov khoom muag muag, cov ntsaws ruaj ruaj, los yog cov ntxig rau hauv ib feem, txhim kho nws txoj haujlwm thiab kev ua haujlwm.

 

- Txhim kho qhov zoo nkauj: Muab ob npaug rau txhaj tshuaj molding ua rau kev tsim cov khoom nrog cov qauv tsim, cov qauv, thiab cov qauv xim uas yuav nyuaj lossis tsis tuaj yeem ua tiav nrog cov txheej txheem molding.

 

Zuag qhia tag nrho, ob chav txhaj tshuaj molding yog ntau yam thiab muaj txiaj ntsig txheej txheem uas yog siv los tsim cov khoom zoo, qhov nyuaj rau ntau yam kev siv, suav nrog tsheb, khoom siv, khoom siv hluav taws xob, khoom siv kho mob, thiab lwm yam.
