Cov pellets yas yog pub rau hauv ib kawg ntawm lub thoob thiab xa nws qhov ntev los ntawm cov ntsia hlau thaum nws tig. Nyob rau ntawm cov yas txoj kev taug kev mus rau qhov ntev ntawm cov ntsia hlau thiab lub thoob nws yog melted, compressed thiab yuam los ntawm ib tug tsis rov qab valve (check nplhaib, pob check). Raws li cov yas molten raug yuam hla lub valve tsis rov qab thiab xa mus rau pem hauv ntej ntawm lub hau ntsia hlau, cov ntsia hlau raug yuam rov qab rau hauv lub thoob.

Kev tshawb fawb moulding txoj kev xav pom zoo tias cov pwm yuav tsum tau ntim nrog molten yas kom sai li sai tau rau 90-95% ntawm tag nrho qhov hnyav, qeeb qhov nrawm raws li qhov seem ntawm seem tau ntim, thiab hloov mus rau qhov siab "tuav" theem xwb. raws li ib feem yog sau thiab pib ntim. Lub sijhawm tuav no yog ib feem tseem ceeb ntawm cov txheej txheem. Qhov no thaum qhov kawg ntim ntawm qhov tshwm sim thiab thaum ntau ntawm cov cua sov hloov tawm ntawm qhov molded thiab mus rau hauv pwm hlau. Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau, yuav tsum muaj cov yas molten txaus nyob rau hauv pem hauv ntej ntawm lub hau ntswj kom muaj peev xwm hloov tau qhov Tuav Siab los ntawm kev sib tw khiav thiab dhau ntawm qhov molded.

Lub hom phiaj yog tuav lub siab tiv thaiv ib feem kom txog rau thaum nws tau txias txaus kom qhov ntev thiab qhov tsos thaum ejected los ntawm pwm. Qhov no tsuas yog ua tiav nrog lub cushion ntawm yas nyob rau hauv pem hauv ntej ntawm lub hau.
