Qhov loj tshaj plaws ntawm HDPE hauv kev txhaj tshuaj molding yog nws cov kua dej zoo thiab ua kom dav kub ntau yam. Nws tuaj yeem sau cov pwm ua nyuaj hauv lub xeev molten thiab yog qhov tsim nyog rau kev tsim cov khoom me me lossis cov khoom lag luam nyias. Qhov cua txias thiab solidification ceev yog nrawm nrawm, tab sis nws yooj yim kom kho kom zoo dua los ntawm kev kho lub sijhawm tuav thiab siab.
HDPE yog rhiab rau pwm txias thaum txhaj tshuaj molding. Tsim kom muaj kev ua kom muaj zog ua kom muaj qhov kub thiab txias tuaj yeem txo cov kev ntxhov siab sab hauv thiab qhov tsis xws luag, tab sis kev kub siab dhau yuav ua rau muaj kev nyuaj. Nws cov khoom muaj cov khoom muaj zog zoo tab sis tsis muaj zog rigidity. Nws yog feem ntau siv los tsim cov khoom lag luam hnav xws li cov khoom ua si txhua hnub thiab cov khoom ua si uas tsis tas yuav muaj zog. Tus Pwm Tsim Tsim yuav tsum tau tseg Shrinkage Allowance thiab ua kom zoo dua cov demolding lub kaum ntse ntse kom ntseeg tau tias cov khoom tiav zoo ntawm cov khoom tiav.

HDPE
HDPE (high-ntom polyethylene) muaj cov zoo corrosion tsis kam thiab yooj. Nws feem ntau siv nyob rau hauv kev txhaj tshuaj moulding ntau lawm cov thawv ntau, yam muaj thiab lwm yam khoom siv yas. Nws yog rhuab thiab melted thiab tom qab ntawd txhaj rau cov pwm kom nrawm moulding, uas haum rau kev tsim ntau ntau pawg ntau lawm.
