Cov txheej txheem ntawm kev nqus tshuaj

txhaj tshuaj moldingyog piav qhia ua ib qho txheej txheem tsim khoom rau kev tsim cov khoom thiab cov khoom los ntawm thermoplastics thiab thermosetting cov khoom. Tsab xov xwm no piav qhia txog txoj kev injection molding thiab tshwj xeeb tshaj yog yuav ua li cas cov khoom nrog cov ntsiab lus siab heev raug tsim hauv txoj kev injection molding.

Tsim thiab Prototyping

Cov txheej txheem injection molding pib nrog kev ua, qhov twg ib qho khoom lossis ib qho khoom raug tsim thiab kos. Qhov no yog ua los ntawm cov engineer siv CAD (computer-aided design) programs los tsim cov duab 3D tiag tiag ntawm cov khoom. Cov kauj ruam tom ntej yog kev tsim cov qauv uas yog siv los tshuaj xyuas qhov tsim raws li nws cov kev ua tau zoo thiab pom kev.

Cov Cuab Yeej thiab Mold Tsim

Tom qab cov txheej txheem no tau ua tiav, cov kauj ruam tom ntej yog kev tsim cov qauv uas tsim los ua kom haum rau cov qauv ntawm qhov chaw. Cov khoom rau kev tsim cov qauv uas siv rau kev ntxig cov qauv tau tsim nrog kev txawj ntse zoo heev, ua rau lawv muaj peev xwm ua tau kom tuav tau cov siab thiab kub siab ntawm txoj haujlwm ntxig cov qauv.

Kev Xaiv Khoom thiab Kev Npaj

Lawv hais tias cov khoom yog ib qho ntawm cov ntsiab lus tseem ceeb tshaj plaws ntawm kev ntxig cov qauv. Cov thermoplastic pellets uas siv yog raws li qhov chaw uas npaj rau lawv cov ntsiab lus xws li lub zog, kev hloov pauv, thiab txawm tias kub tiv thaiv ntawm qhov chaw ntawd. Lawv tom qab ntawd mus dhau ib txheej txheem ntawm kev qhuav tom qab ntawd yog qhov kev thov kub txog thaum muaj qhov dej molten kom tso cai rau cov pellets kom raug ntxig rau hauv cov qauv.

Kev Ntxig thiab Kev Txias

Cov yas uas melted tau raug injected mus rau hauv qhov cavity ntawm lub mold hauv qab qhov siab uas nplij qhov chaw sab hauv ntawm qhov cavity. Cooling ntawm lub mold yog ua kom txias thiab solidify cov yas-formed feem. Qhov ceev ntawm qhov txias yog tswj hwm kom zoo kom tsis txhob muaj distortion thiab kom tau qhov tseeb uas xav tau.

Ejection thiab Xyuas

Thaum cov kev xav tau txias tau ua tiav, lub mold qhib, thiab qhov feem uas tau molded raug ejected tawm ntawm qhov cavity. Cov khoom siv lubrication raug tshuaj xyuas rau txhua yam traces ntawm defects, tshwj xeeb tshaj yog rau flashing, sink marks thiab tsis tiav filling. Cov defects pom tau raug kho thiab cov npoo ntawm qhov feem uas rough thiab lwm yam khoom plig raug txiav tawm thaum kawg ntawm txoj haujlwm.

Peb tsom mus rau peb cov neeg siv khoom xav tau, nrog rau kev tsom mus rau kev muab cov khoom plig yas injection molded zoo. Ua ib lub koom haum uas txaus siab rau kev saib xyuas cov ntsiab lus, kev tsim kho thiab kev txaus siab ntawm cov neeg siv khoom, HSM muab thiab kho cov kev daws teeb meem yas injection molding rau cov neeg siv khoom thoob plaws lub ntiaj teb. Yog tias yog kev tsim qauv lossis kev tsim khoom ntau, Cov neeg siv khoom tuaj yeem ntseeg HSM's injection molding muaj peev xwm los muab cov khoom zoo thiab kev ua haujlwm rau lawv cov khoom.
