Cov txheej txheem tsim cov yas fasteners feem ntau suav nrog ob peb kauj ruam tseem ceeb: kev npaj cov khoom raw, molding, ua, thiab tom qab- ua.
Ua ntej, xaiv cov khoom siv raw yog thawj kauj ruam hauv kev tsim cov yas fasteners. Cov ntaub ntawv yas siv feem ntau suav nrog polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), thiab polyester (PET). Cov ntaub ntawv no muaj lub zog zoo txhua yam, corrosion kuj, thiab moldability. Kev ziab kom qhuav ntawm cov khoom siv raw yog qhov tseem ceeb los tiv thaiv kev ya raws los ntawm kev cuam tshuam rau kev ua haujlwm tom ntej.
Tom ntej no yog cov txheej txheem molding, feem ntau yog siv kev txhaj tshuaj molding, extrusion molding, los yog compression molding. Kev txhaj tshuaj molding yog cov txheej txheem ntau tshaj plaws, qhov twg cov yas granules qhuav tau rhuab mus rau lub xeev molten thiab tom qab ntawd txhaj rau hauv pwm, qhov chaw uas lawv txias los ua cov khoom xav tau. Extrusion molding yog tsim rau kev tsim cov yas ntev, nyias nyias thiab feem ntau siv rau hauv kev tsim cov kav dej yas.
Tom qab molding, post- tej zaum yuav tsum tau ua, xws li deburring, sanding, thiab nto kho. Cov kauj ruam no txhawm rau txhim kho cov khoom zoo li thiab kev ua tau zoo. Thaum kawg, kev tshuaj xyuas zoo yog ua los xyuas kom meej tias qhov ntev, lub zog, thiab kev ntseeg siab ntawm cov yas fasteners ua tau raws li cov qauv tsim nyog.
