Ntsiab cai thiab hom hom phwj fais ntawm txhaj tshuaj molding tshuab
May 16, 2019
Cov hauv paus ntsiab lus ntawm lub hau ntsaws taub ntawm cov tshuaj molding tshuab:
Lub ntsiab ntawm tus ntsia hlau ciav hlau yog cov kab ntsig pa uas muaj peev xwm muab tso rau hauv qhov zawj ntawm lub tshooj melting los yog qhov ntsuas ntawm cov ntsia hlau los yog cov cylindrical ciav hlau tsis muaj qhov zuam tom kawg ntawm cov seem ntsuas. Cov pins raug teem nyob rau hauv ib qho kev tsim, thiab qhov ceev yuav txawv ntawm ib qho mus rau lwm qhov. Tus cylindrical pin yog tsim los ntawm haum tus pin rau hauv lub qhov ntawm lub hau; lub square los yog pob zeb diamond tus pin yog tsim los ntawm milling tus pin ncaj qha rau ntawm lub hau.
Yog tus pins muaj nyob rau hauv thaj chaw melting, tus pin yuav tawg tau lub txaj khoom, rhuav tshem ob theem, khiav cov khoom ua kua thiab ua kua ua ke, thiab nce thaj chaw sib txuas ntawm qhov kawg ntawm txheej txheem cov khoom tawg thiab cov khoom muaj nyob, thiab txhawb Melt. Yog hais tias tus pin tso rau hauv huab cua hloov cheeb tsam, nws cov kev ua haujlwm tseem ceeb yog faib cov dej, nce lub interface, pauv qhov kev coj ua ntawm qhov ndlwg, thiab rearrange cov ndlwg. Muab faib thiab sib txuas ntau lub sij hawm, hloov cov kev taw qhia khiav mus rau homogenize hmoov qhuav thiab kub.
Qhov seem tov yog ib qho kev voj voos nyob hauv qhov kawg ntawm qhov qis qis homogenization, thiab lub sab nraud yog sib npaug rau sab nraud ntawm lub hau ntswj. Cov grooves raug muab faib ua pawg, txhua qhov ntawm yog ib thaj chaw ntawm cov khoom. Cov khoom faib tawm ntawm qhov zawj, ua ke rau hauv qhov chaw sib txuas, ces muab faib thiab sib koom ua ke. Lub hauv paus ntsiab lus zoo li tus pin yam.
Txhaj tshuaj molding tshuab ntsia hlau thawv hom:
1. Gradient hom Gradient ntaus nrau nta: ntev compression seem, lub zog hloov tshiab thaum lub sij hawm yas plawg yog tsawg, thiab nws yog feem ntau siv rau cov khoom uas tsis thermal stability xws li PVC.
2, mutant hom mutant screw nta: luv dua compression seem, ntau lub zog conversion thaum plasticization, feem ntau siv nyob rau hauv polyolefin, paj thiab lwm yam crystalline plastics
3, General-purpose general-purpose screw nta: general-purpose screw nrog muaj zog adaptability, yuav hloov mus ua ntau yam ntawm cov yas, tsis txhob nquag hloov ntawm lub hau ntswj.
