Kev tsim cov pin- hom cable ties suav nrog kev ua cov ntaub ntawv polymer thiab cov txheej txheem molding precision. Cov txheej txheem synthesis ncaj qha cuam tshuam rau cov khoom siv kho tshuab, qhov tseeb qhov tseeb, thiab kev ntseeg tau. Cov txheej txheem tag nrho tuaj yeem muab faib ua raw khoom xaiv thiab pretreatment, extrusion molding, txhaj tshuaj molding ntawm lub xauv mechanism, post- ua, thiab kuaj. Txhua theem yuav tsum muaj kev sib koom tes tswj xyuas kom muaj kev sib luag thiab kev ua haujlwm ntawm cov khoom kawg.
Cov ntaub ntawv raw feem ntau muaj xws li engineering yas granules, feem ntau suav nrog nylon (PA66), polypropylene (PP), polyester (PBT), los yog hloov cov formulations ntawm no. Cov granules no yuav tsum tau ziab ua ntej noj kom tshem tawm cov dej noo thiab tiv thaiv npuas los yog txo lub zog thaum lub sij hawm molding. Qhov kub thiab lub sij hawm ziab ziab yog nyob ntawm cov khoom siv; Piv txwv li, nylon feem ntau yuav tsum tau ziab ntawm 80-120℃rau ob peb teev kom ntseeg tau tias cov ntsiab lus noo noo txo mus rau qib zoo.
Cov hlua txuas txuas ntxiv ntawm txoj hlua khi yog tsim los siv cov txheej txheem extrusion molding. Cov granules qhuav yog pub rau hauv ib qho extruder, uas lawv melted thiab plasticized nyob rau hauv lub cua sov cheeb tsam, ces extruded los ntawm ib tug tuag nrog ib tug tshwj xeeb ntoo khaub lig-sectional duab, tsim ib tug sawb nrog tas mus li hniav. Kev tswj nruj ntawm qhov kub thiab txias qhov profile thiab rub ceev yog tsim nyog thaum lub sij hawm extrusion kom paub meej thiab sib npaug sib npaug ntawm cov hniav profiles, thaum tsis txhob muaj kev ntxhov siab sab hauv lossis qhov tsis xws luag. Tom qab extrusion, lub pluaj yog txias, zoo li tus, thiab qhov txhab rau kev txiav tom qab.
Lub tshuab xauv lub tshuab feem ntau yog tsim los ntawm kev txhaj tshuaj molding, nrog rau lub pluaj lossis los ntawm ob- txheej txheem sib dhos. Hauv kev tsim qauv, cov pwm muaj lub pluaj channel thiab lub kaw lus kaw lus kab noj hniav, thiab cov yas molten ib txhij ua cov pluaj thiab lub xauv rau hauv ib qho kev txhaj tshuaj, kom ntseeg tau tias kev sib txuas lub zog thiab qhov chaw raug. Rau kev tsim cov txheej txheem sib cais, cov txheej txheem xauv yog thawj zaug txhaj tshuaj molded cais, thiab tom qab ntawd ua ke nrog cov pluaj los ntawm kev sib cuam tshuam los yog thermal vuam. Kev tswj xyuas meej ntawm kev txhaj tshuaj, tuav lub sijhawm, thiab tus nqi cua txias yog qhov tseem ceeb thaum txhaj tshuaj molding los tiv thaiv kom tsis txhob shrinkage, warping, los yog cov hniav tsis zoo nyob rau hauv lub xauv mechanism.
Tom qab molding, cov hlua txuas tau raug txiav, deburring, tshuaj xyuas saum npoo, thiab kev ntsuas kev ua haujlwm tsim nyog, suav nrog lub zog tensile, xauv lub zog tuav, thiab kev txheeb xyuas ib puag ncig. Rau cov kev siv tshwj xeeb, cov khoom siv ntxiv xws li iav fiber reinforcement, nplaim retardants, los yog UV stabilizers tuaj yeem qhia tau thaum lub sij hawm ua ke los txhim kho cov cua sov, tiv thaiv kev laus, lossis hluav taws kub.
Zuag qhia tag nrho, cov txheej txheem synthesis ntawm cable sib txuas ua ke cov khoom siv polymer ua tshuab nrog precision pwm tsim. Lub qhov rais txheej txheem ruaj khov yuav tsum raug tsim los hla ntau yam tsis xws li qhov kub thiab txias, siab, thiab ceev kom ua tiav siab - cov khoom zoo uas muaj lub zog siab, ua haujlwm ntev, thiab yooj yim ntawm kev sib dhos. Cov txheej txheem no tsis tsuas yog qhia txog kev sib koom ua ke ntawm cov ntaub ntawv tshawb fawb thiab kev tsim khoom siv thev naus laus zis tab sis kuj tseem tsim lub hauv paus ruaj khov rau lawv cov ntawv thov kev ntseeg siab hauv ntau yam.
