Mould kub tshuab, tseem hu ua pwm kev tswj qhov kub thiab txias, uas yog siv dav hauv ntau qhov kev lag luam xws li yas moulding, lub teeb qhia phaj tuag casting, roj hmab log tsheb, yob, tshuaj lom neeg, sib txuas, thiab sib xyaw sab hauv. Hauv kev paub dav, nws yog hu ua cov khoom siv tswj kev ntsuas kub, uas suav nrog kev tswj qhov kub thiab txias hauv ob yam: cua sov thiab txias.Tam sim no lub tshuab kub pwm feem ntau muab faib ua cov dej kub ua tshuab thiab cov roj kub ua tshuab.Qhov kub tswj los ntawm lub pwm kub tshuab feem ntau tuaj yeem ncav cuag qhov sib ntxiv lossis rho tawm 0.1 degrees.
Pwm kub tswj tau siv dav hauv kev lag luam plastics, thiab lawv cov haujlwm tseem ceeb yog:
1. Txhim kho cov khoom lag luam molding ua haujlwm;
2. Txo cov khoom tsim tsis raug;
3. Txhim kho cov tsos ntawm cov khoom thiab suppress khoom kho teeb meem;
4. Ua kom zoo dua ntawm kev nce qib, txo kev siv zog thiab txuag hluav taws xob.
Tseem muaj ntau chav rau siv ntawm lub tshuab pwm kub nyob hauv kev lag luam tuag-ua lag luam, tshwj xeeb hauv kev tsim khoom siv ntawm cov khoom siv hlau nplaum thiab txhuas cov khoom siv alloys. Cov pwm tsis sib xws los yog pwm tsis zoo yuav ua rau qhov loj ntawm cov hlau nplaum tsis ruaj khov, thiab cov casting yuav txawv thaum lub txheej txheem ntau lawm. Cov tsis zoo xws li lub siab thermal, pwm plhaw, qhov kev nyuaj siab saum npoo, lub ntsej muag ntsws, thiab ua npuas dej kub. Nws tseem muaj qhov cuam tshuam rau kev voj voog ntau lawm, xws li sau lub sijhawm, cua txias lub sijhawm thiab tshuaj tsuag lub sijhawm tag nrho cov khoom hloov tsis ruaj khov. Lub neej ntawm cov pwm tseem yuav ua rau thermal tawg ntawm cov hlau kim vim qhov cuam tshuam ntawm overcooling thiab overheating, uas ua rau nrawm nws laus.
Hauv lub Hoobkas tshiab, teb rau kev sib tw hauv kev ua lag luam, kev lag luam ua lag luam ntawm kev txuag tus txiv neej, txhim kho kom zoo, thiab txo tus nqi yog qhov nrawm. Kev siv lub tshuab ua pwm kub tuaj yeem txo lub sijhawm preheating ntawm lub pwm, txhim kho qhov zoo ntawm cov khoom ua tiav thiab ua tiav cov tshuab ua kom tiav. Kev txhim kho lub neej pwm yog qhov tsim nyog los txhawm rau ua kom cov khoom lag luam.
