Rotational molding txheej txheem yog ib ceg tseem ceeb ntawm cov yas molding ua

Rotational molding txheej txheem yog ib ceg tseem ceeb ntawm yas molding processing.Txij thaum lub sij hawm tuaj txog ntawm lub 1940s, tom qab ntau tshaj li ib nrab xyoo ntawm txoj kev loj hlob, nws cov cuab yeej thiab technology yog nce zoo meej, nyob rau hauv cov teb chaws Europe tsim lub teb chaws tau lug siv, los ntawm cov me nyuam cov khoom ua si. tsheb yas qhov chaw, mus txog rau lubloj engineering yas khoom.Tshwj xeeb tshaj yog loj thiab tshwj xeeb-zoo li tus hollow khoom, vim hais tias ntawm cov kev txwv ntawm cov tsoos txheej txheem ntawm nws tus kheej yam ntxwv, tsuas yog cia siab rau rotomolding molding txheej txheem kom tiav.

Qhov zoo

1, Tus nqi qisrotational molding pwm- tib qhov loj ntawm cov khoom, tus nqi ntawm rotomolding pwm yog li 1/3 rau 1/4 ntawm tus nqi ntawm cov tshuab molding, txhaj tshuaj molding, haum rau cov khoom yas loj;

2, Lub zog ntug ntawm cov khoom yog qhov zoo - lub thickness ntawm ntug ntawm cov khoom yuav ua tau ntau tshaj 5 hli, tag nrho cov teeb meem ntawm nyias ntug ntawm cov hollow khoom;

3, Rotomolding yas tuaj yeem tso ntau yam ntawm Mosaic daim;

4, Cov duab ntawm cov khoom rotomolding tuaj yeem ua tau zoo heev, thiab lub thickness tuaj yeem ntau dua 5 hli;

5, Rotomolding yas tuaj yeem tsim cov khoom kaw tag nrho;

6, Rotomolding cov khoom yas tuaj yeem sau nrogfoaming cov ntaub ntawv kom ua tiav kev txuag hluav taws xob;

7, Tsis tas yuav kho cov pwm, phab ntsa tuab ntawm cov khoom rotomolding tuaj yeem hloov kho dawb (ntau tshaj 2 hli);

8, Haum rau molding loj thiab ntxiv-loj qhov chaw;

9, Rotational molding khoom yog ib qho yooj yim los hloov cov xim ntawm cov khoom - rotaional molding txhua lub sij hawm cov khoom ncaj qha ntxiv rau pwm, yog li ntawd tag nrho cov ntaub ntawv mus rau hauv cov khoom los ntawm cov pwm tom qab tshem tawm cov molding tom ntej yuav tsum tau ntxiv cov khoom.Thaum peb siv ntau tshaj ib qho pwm rotomolding molding ntawm tib cov khoom yas, tab sis kuj muaj pwm sib txawv los ntxiv cov xim sib txawv ntawm cov ntaub ntawv, tib lub sij hawm rotomolding yas khoom ntawm cov xim sib txawv;

10, Txuag raw cov ntaub ntawv - cov phab ntsa thickness ntawm rotomolding yas khoom yog ntau yam thiab me ntsis thicker chamfer, yog li nws muaj peev xwm muab tag nrho ua si rau cov efficiency ntawm cov ntaub ntawv, yog conducive rau txuag raw cov ntaub ntawv;Tsis tas li ntawd, tsis muaj qhov khiav, rooj vag thiab lwm yam khoom pov tseg hauv cov txheej txheem molding.Thaum nws raug kho, yuav luag tsis muaj nqi rov ua dua tshiab hauv cov txheej txheem ntau lawm, yog li cov txheej txheem rau kev siv cov khoom siv siab heev.
