5 Hom Plastic Moulding Rau Cov Khoom Siv Yas Kev Cai Manufacturers

Muaj ob hom plastics: thermoplastic thiab thermo-rigid. Thermoplastics yog meltable thiab thermoplastic tsis yog. Qhov txawv yog li cas cov polymers raug tsim. Polymers, los yog chains ntawm atoms, zoo li ib-dimensional hlua nyob rau hauv thermoplastics, thiab yog hais tias lawv yaj, lawv muaj peev xwm coj mus rau ib tug tshiab duab. Nyob rau hauv thermo-rigid lawv yog peb-dimensional tes hauj lwm uas ib txwm khaws lawv cov duab. Ntau yam txheej txheem yog siv los ua cov yas pwm los yog pwm, qee qhov tsuas yog ua haujlwm rau cov thermoplastics, lwm tus tsuas yog siv rau thermo-rigid thiab qee cov txheej txheem ua haujlwm rau ob qho tib si.

Kev rho tawm

Extrusion yog txheej txheem molding uas pib nrog "raws" cov khoom yas xws li granules, hmoov, lossis pearls. Ib lub hopper pub cov yas rau hauv lub rotating chamber. Lub chamber, hu ua extruder, sib tov thiab yaj cov yas. Cov yas yaj yog yuam tawm los ntawm kev tuag thiab siv cov khoom tiav. Cov khoom ntog rau ntawm txoj siv conveyor uas nws tau txias nrog dej thiab txiav. Qee cov khoom uas tuaj yeem tsim los ntawm extrusion muaj xws li nplooj ntawv, zaj duab xis thiab raj.

 

Kev txhaj tshuaj molding

Kev txhaj tshuaj molding siv tib txoj cai raws li extrusion. Cov yas nyoos yog pub los ntawm lub hopper rau hauv chav cua sov. Txawm li cas los xij, es tsis txhob raug yuam kom dhau los ntawm kev tuag, nws raug yuam mus rau hauv pwm txias nyob rau hauv siab. Cov yas txias thiab solidifies, thiab cov khoom yog ntxuav thiab ua tiav. Qee cov khoom tsim los ntawm kev txhaj tshuaj muaj xws li ntim butter, lub raj mis, cov khoom ua si thiab cov rooj tog vaj tog tsev.

 

Tshuab moulding

Tshuab moulding siv cua txhaj tshuaj tom qab cov yas tau extruded los yog txhaj. Extrusion tshuab moulding siv ib tug tuag uas tsim ib tug kub yas raj nrog ib tug txias pwm nyob ib ncig ntawm nws. Cov cua compressed yog txhaj los ntawm lub raj kom yuam cov yas kom coj cov pwm zoo. Qhov no tso cai rau cov tuam txhab tsim cov duab txuas ntxiv thiab tsis sib xws, tab sis yuav tsum tau txhaj tshuaj-pwm txhua tus ntawm lawv. Txhaj- tshuab kuj tseem siv cov pwm txhaj tshuaj, tab sis es tsis txhob tau txais cov khoom tiav, cov pwm yog ib theem nruab nrab uas cov yas yog rhuab kom tshuab mus rau nws cov duab kawg hauv ib qho pwm txias.

 

Kev sib txuam moulding

Compression molding yog cov txheej txheem ntawm kev noj cov yas ntim ua ntej, muab tso rau hauv pwm, thiab tom qab ntawd siv lwm pwm los txhuam los yog compressed rau hauv thawj pwm. Cov txheej txheem tuaj yeem ua tsis siv neeg lossis phau ntawv thiab tsim nyog rau ob qho tib si thermoplastic thiab thermo-rigid cov ntaub ntawv.

 

Thermoformed

Thermoforming yog cov txheej txheem ntawm cua sov ib zaj duab xis yas yam tsis muaj melting nws, softening nws txaus los ua daim ntawv ntawm pwm tiv thaiv uas nws yog nias. Cov chaw tsim khoom ua rau cov yas coj cov duab uas xav tau siv lub zog siab, lub tshuab nqus tsev lossis cov txiv neej pwm. Tom qab cov khoom tiav tau txias lawm, nws raug tshem tawm ntawm pwm thiab cov khoom seem yog rov siv dua los siv rau hauv zaj duab xis tshiab.

 

Yas txhaj tshuaj molding txheej txheem

Kev txhaj tshuaj molding yog ib txoj hauv kev tseem ceeb ntawm kev ua cov yas. Thawj kauj ruam hauv kev txhaj tshuaj molding yog pub cov yas granules rau hauv lub plhaw, uas tom qab ntawd pub cov granules rau hauv lub tog raj kheej. Lub thoob yog rhuab thiab muaj ib tug alternate ntsia hlau los yog ram injector. Ib qho kev hloov ntsia hlau feem ntau pom ntawm cov tshuab uas tsim cov khoom me me. Lub reciprocating ntsia hlau crushes cov granules, ua rau nws yooj yim dua rau cov yas liquefied. Nyob rau hauv pem hauv ntej ntawm lub thoob, lub reciprocating ntsia hlau tsav lub liquefied yas rau pem hauv ntej, txhaj cov yas los ntawm lub nozzle thiab mus rau hauv lub puab puab. Tsis zoo li lub thoob, cov pwm yog khaws cia txias kom tawv yas rau hauv qhov tseeb. Cov phaj pwm raug kaw los ntawm lub phaj loj (xa mus rau lub phaj txav tau). Lub phaj txav tau txuas nrog lub piston hydraulic, uas ua rau lub zog ntawm pwm. Qhov kaw clamping ntawm cov pwm yas tiv thaiv nws los ntawm kev khiav, uas yuav tsim deformations nyob rau hauv cov khoom tiav.
