Pwm kub tshuab, tseem hu ua pwm kub tswj tshuab, yog dav siv nyob rau hauv yas molding, lub teeb qhia phaj tuag-casting, roj hmab log tsheb, rollers, tshuaj reactors, bonding, banburying thiab lwm yam lag luam. Hauv kev nkag siab dav, nws yog hu ua cov cuab yeej tswj qhov kub thiab txias, uas suav nrog kev tswj qhov kub thiab txias hauv ob qho tib si cua sov thiab khov.
Kev siv ntawmpwm kub tshuabnyob rau hauv kev lag luam plastics yog feem ntau, lub luag haujlwm tseem ceeb yog:
1. Txhim kho molding efficiency ntawm cov khoom;
2. Txo kev tsim cov khoom tsis raug;
3. Txhim kho qhov zoo ntawm cov khoom thiab txo qhov tsis xws ntawm cov khoom;
4. Ceevnce kev nce qib ntau lawm, txo kev siv hluav taws xob thiab txuag hluav taws xob.
Tseem muaj ntau chav rau daim ntawv thov ntawm lubpwm kub tshuabhauv kev lag luam tuag casting, tshwj xeeb hauv kev tsim cov magnesium alloys thiab aluminium alloys. Cov pwm kub tsis sib xws lossis tsis tsim nyog yuav ua rau qhov tsis ruaj khov ntawm qhov castings, thiab deformation ntawm castings thaum lub sij hawm tsim khoom. Cov teeb meem xws li thermal siab, pwm sticking, deg depression, sab hauv shrinkage kab noj hniav thiab thermal npuas yog generated. Nws kuj tseem cuam tshuam rau lub voj voog ntau lawm, xws li lub sijhawm sau, lub sijhawm txias thiab lub sijhawm txau tag nrho tsim cov khoom tsis ruaj khov. Lub neej ntawm cov pwm kuj tseem yuav ua rau kub tawg hauv cov hlau kim vim qhov cuam tshuam ntawm supercooling thiab superheating, ua kom nws cov laus.
Nyob rau hauv ib lub Hoobkas niaj hnub, teb rau kev sib tw ua lag luam, nws yog ib qho tseem ceeb kom txuag tau cov neeg ua haujlwm, txhim kho kom zoo, thiab txo cov nqi. Kev siv cov tshuab pwm kub tuaj yeem txo cov pwm preheating lub sij hawm, txhim kho qhov zoo ntawm cov khoom tiav, thiab tag nrho automate ntau lawm. Txhim kho pwm lub neej yog ib qho tseem ceeb ntawm kev tsim cov khoom tsim tau.
Kev siv ntawmkub tswj tshuabhauv lwm qhov kev lag luam yog qhov tsim nyog rau cov khoom siv sib xyaw, thiab cov npe sib txawv. Nws yog hu ua roj rhaub nyob rau hauv cov menyuam kub tswj ntawm PVC ntawv, kub tswj ntaus ntawv nyob rau hauv cov khoom extruder, thiab kub tswj system los yog kub tswj tshuab nyob rau hauv roj hmab tov khoom. Kev kub ceev ceev, ua raws li cov txheej txheem ua kom sov. Tom qab cua sov hauv cov khoom siv roj hmab, yuav tsum tau ua kom txias thiab txias mus ntev.
