Low Pressure Overmolding yog dab tsi?
Tsis tshua muaj siab overmolding yog hais txog cov txheej txheem ntawm kev siv cov khoom siv thib ob dhau ntawm lub hauv paus substrate uas siv cov kev txhaj tshuaj tsawg. Tsis zoo li ib txwm overmolding uas siv siab - lub tshuab siab los yuam cov ntaub ntawv rau hauv pwm, qis -siab overmolding siv txo siab los tsim kom muaj kev tswj xyuas ntau dua, cov txiaj ntsig zoo. Qhov tsis tshua muaj siab tso cai rau kev siv cov khoom rhiab, xws li cov khoom siv hluav taws xob lossis cov khoom siv me me, tsis muaj kev pheej hmoo rau kev puas tsuaj thaum lub sij hawm molding. Nws yog txheej txheem ntau yam siv los ua ke ob yam khoom sib txawv, feem ntau hauv cov ntawv thov uas xav tau yooj yim, tiv thaiv, lossis kev zoo nkauj. Kev txhaj tshuaj tsawg ua kom cov ntaub ntawv ntws zoo thiab sib npaug ntawm lub hauv paus tivthaiv, tsim kom muaj kev sib raug zoo thaum tiv thaiv cov qauv hauv qab.
Cov Txheej Txheem Tsis Txaus Siab Overmolding
Qhov qis- cov txheej txheem siab dhau los ua ke ua ke ob txoj haujlwm tseem ceeb: muab cov khoom sib xyaw rau hauv pwm thiab tom qab ntawd qhwv nws nrog cov khoom siv thib ob txhaj rau ntawm qhov tsis tshua muaj siab. Cov txheej txheem no txhawb kev tsim cov duab nyuaj, tso cai rau cov khoom siv softer kom ua raws li kev ruaj ntseg ntawm lub substrate thaum tuav cov thawj daim ntawv thiab kev ua haujlwm ntawm ob txheej. Thaum lub sij hawm molding, cov khoom overmolding yog rhuab thiab coj mus rau hauv lub pwm kab noj hniav, qhov twg nws nyob ib ncig ntawm lub tso substrate. Vim tias qhov kev txhaj tshuaj siab tsawg, lub substrate yog tiv thaiv los ntawm distortion, uas ua rau muaj zog, pom kev txaus siab rau cov khoom kawg.
Cov kauj ruam tseem ceeb
Qhov chaw substrate:Lub hauv paus tivthaiv, txawm tias hlau, yas, lossis cov khoom siv hluav taws xob rhiab heev, ua tib zoo muab tso rau hauv pwm kab noj hniav, thiab ua kom sov hauv kev npaj rau molding.
Pwm Insertion: Cov khoom tiv thaiv yuav tsum tau muab tso rau hauv ib nrab ntawm cov pwm. Lwm ib nrab ntawm cov pwm raug kaw los tsim ib qho chaw nyob ib ncig ntawm cov khoom. Cov khoom siv hluav taws xob lossis cov khoom uas xav tau encapsulation tau muab tso rau hauv cov pwm kab noj hniav. Lub sijhawm thauj khoom feem ntau yog 5-10 vib nas this.
Overmolding: Ib lub tshuab moulding uas tsis tshua muaj siab maj mam muab cov kua dej thermoplastic rau hauv cov pwm kab noj hniav kom txog thaum nws puv. Cov khoom siv molten yog txhaj rau hauv pwm ntawm qhov tsis tshua muaj siab. Kev txhaj tshuaj tas mus li yog siv los them nyiaj rau shrinkage thaum lub caij txias.
Tsawg-Kev Txhaj Tshuaj: Cov khoom siv thib ob, xws li thermoplastics, elastomers, lossis silicone compounds, yog maj mam txhaj ib ncig ntawm lub substrate ntawm kev txo qis.
Txias & Solidification: Cov khoom siv txhaj tshuaj tau tso cai kom txias, ua kom muaj kev ruaj ntseg thiab ruaj khov ntawm ob cov ntaub ntawv.
Ntu Ejection: Thaum cov khoom tiav lawm, nws raug tshem tawm ntawm pwm, npaj rau kev siv lossis kuaj.
Cov khoom siv nyob rau hauv Low Pressure Overmolding
Cov thermoplastics: Cov yas no, xws li polypropylene (PP), polyethylene (PE), thiab polyvinyl chloride (PVC), yog dav siv nyob rau hauv qis - siab overmolding vim lawv yooj, tsis tshua muaj nqi, thiab yooj yim ntawm kev ua.
Elastomers: Cov ntaub ntawv zoo li cov thermoplastic elastomers (TPE) thiab roj hmab feem ntau xaiv rau lawv qhov yooj yim thiab muaj peev xwm los tsim cov khoom muag, tactile hauv cov neeg siv khoom lossis cov khoom siv kho mob.
Engineering Plastics: Cov ntaub ntawv muaj zog xws li polycarbonate (PC), nylon (PA), thiab polyoxymethylene (POM) yog siv thaum xav tau kev ua haujlwm siab thiab ua haujlwm ntev, tshwj xeeb tshaj yog hauv kev siv tsheb lossis kev lag luam.
