Lub tshuab tshuab zaj duab xis yog ua los ntawm high-voltage polyethylene thiab low-pressure polyethylene li raw khoom. Nws yog rhuab thiab nyem tawm, tsam plab thiab ncab, thiab ua rau hauv cylindrical zaj duab xis. Cia peb ua kom paub cov txheej txheem ntxuav ntawm lub tshuab molding pwm header
Ntxuav lub taub hau thiab kauv lub cev. Thaum ntxuav, siv cov roj paraffin lossis methyl silicon, thiab maj mam so cov tshuaj txhuam nrog 1000 qhov chaw ntawm cov ntawv xuab zeb kom txog thaum nws huv. Thaum hloov cov khoom siv, qhov kub thiab txias (qhov sib txawv thiab cov khoom siv ntshiab yog qhov sib txawv ntawm qhov kub thiab txias) thaum hloov cov khoom siv.
Qhov tseem ceeb yog tias nyob rau hauv cov txheej txheem ntau lawm, nws yog qhov zoo tshaj plaws los ntxiv me ntsis ntawm methyl silicon roj rau cov khoom nyob rau hauv ib lub lim tiam, uas yog, koj muaj peev xwm lubricate lub ntsia hlau qauv, thiab koj muaj peev xwm tshem tawm cov pwm.
