Txhua qhov yas yuav tsum muaj cov txheej txheem tsim khoom tshwj xeeb uas tuaj yeem sib txawv ntawm ib yam khoom mus rau lwm qhov.Kev txhaj tshuaj molding yog siv los tsim cov khoom siv thaum tshuab moulding yog siv los ua cov khoom yas nrog rau qhov chaw hollow, xws li lub raj mis thiab ntim.
Txhaj stretch tshuab moulding combines cov kev txhaj tshuaj molding thiab tshuab molding txheej txheem.Cov yas yog thawj molded rau hauv ib qho khoom preform, los tsim ib tug threaded lub raj mis caj dab.Thaum lub preform txias nws yog pub rau hauv lub tshuab nqus tsev tshuab mould.Tom qab ntawd lub preform yog reheated siv lub tshuab cua sov infrared thiab tshuab mus rau hauv lub raj mis yas nrog cua compressed cua.
Txoj Kev Txhaj Molding
Kev txhaj tshuaj molding yog siv los tsim cov khoom ntim ntau dua ntawm cov khoom yas xws li qhov loj ntawm cov khoom loj mus rau cov khoom me me uas xav tau qhov tseeb micro-precision.
Muaj ntau ntau hom kev tsim khoom raws li kev txhaj tshuaj molding, xws li thermoplastic txhaj molding, tshaj molding, ntxig molding, txias khiav molding thiab kub khiav molding.
Thermoplastic Txhaj Molding
Thermoplastic txhaj molding siv thermoplastic polymer, txhais tau tias nws hloov mus rau lub xeev ua kua thaum rhuab.Tsis zoo li cov thermoset yas uas txias rau hauv cov khoom ruaj khov, cov thermoplastics tuaj yeem xa mus rau hauv cov kua tom qab txias rau hauv cov khoom.
Overmolding
Overmolding, los yog ob qho kev txhaj tshuaj molding, yog txheej txheem uas npog cov pwm txhaj tshuaj rau lwm yam khoom, xws li hlau, txhawm rau txhim kho kev ua haujlwm lossis ua haujlwm ntev ntawm cov khoom.Cov khoom siv roj hmab zoo li, hu ua thermoplastic elastomer (TPE), yog cov khoom siv ntau dhau.Ib qho piv txwv ntawm daim ntawv thov TPE overmold yog tus tuav tuav ntawm tus txhuam hniav.Overmolds kuj tseem siv tau los kaw cov khoom lag luam nrog cov khoom ua los ntawm ntau cov pwm txhaj tshuaj.
Ntxig Moulding
Zoo li overmolding, ntxig molding yog ib qho kev txhaj tshuaj molding txheej txheem uas muab ob los yog ntau tshaj cov khoom rau hauv ib qho khoom tiav.Ntxig txhaj tshuaj molding inserts ib tug tivthaiv rau hauv lub txhaj tshuaj pwm kab noj hniav thiab cov khoom yas yog sau nyob ib ncig ntawm lub insert.Inserts tuaj yeem ntxiv dag zog rau cov khoom lag luam thiab tshem tawm qhov xav tau ntawm cov khoom ntxiv kom txo cov khoom hnyav.
Txias Runner Txhaj Molding
Cov neeg khiav dej txias pwm siv lub tshuab ua kom puv cov neeg khiav dej num uas txhaj cov yas yas rau hauv pwm kab noj hniav.Nyob rau hauv 2 phaj pwm, lub tshuab khiav thiab qhov chaw txuas nrog, thiab ib qho ejection system yuav raug siv los cais cov khub ntawm pwm.Cov neeg khiav dej txias tuaj yeem txo cov khib nyiab los ntawm kev rov ua dua thiab rov ua dua cov khoom, tab sis qhov no tuaj yeem ua rau lub sijhawm tag nrho. .Cov tshuab khiav txias tuaj yeem siv rau ntau hom polymers thiab tuaj yeem tso cai rau kev hloov xim yooj yim.
Kub Khiav Pwm
Kub khiav pwm siv lub manifold kom sov melted yas resin thiab xa cov khoom los ntawm lub rooj vag mus sau cov pwm kab noj hniav.Ob lub ntsiab ntawm cov kub khiav pwm yog sab nraud rhuab thiab sab hauv rhuab.Cov pwm sab nraud tuaj yeem siv tau nrog cov khoom siv polymer uas tsis tshua muaj kev cuam tshuam rau thermal variations thaum nyob rau hauv rhuab kub khiav pwm tso cai rau kev tswj zoo ntawm cov khoom ntws.
Vim tias kub khiav molding tsis tas yuav siv cov neeg khiav dej num, cov khoom siv pov tseg yuav raug txo kom tsawg thiab cov khoom siv rov ua dua tshiab thiab rov ua dua thiab cov txheej txheem ntawm cov yas yas tsis cuam tshuam rau tag nrho cov sij hawm khiav.
Tshuab Moulding txheej txheem
Thaum lub sij hawm tshuab molding txheej txheem, cov khoom siv yas raw yog zoo li lub raj hollow nrog ib qho qhib kawg hu ua parison.Lub parison yog nias rau hauv ib lub pwm hlau txias thiab compressed cua yog yuam mus rau hauv parison.Thaum cov yas tsim txias thiab tawv, cov pwm hlau qhib thiab tshem tawm cov khoom.
