Kupanga kwachitsulo kwachitsulo ndi njira yofunika yopangira kukakamiza kutengera pulasitiki ya pulasitiki yachitsulo.Chitsulo cha extruder ndichida chofunikira kwambiri chazitsulo.

Extrusion ndi imodzi mwanjira zazikulu zopangira zitsulo zopanda mafuta ndi chitsulo ndi zida zachitsulo ndikupanga ziwalo. Imeneyi ndi njira yofunikira yokonzekera ndikukonzekera zinthu zosiyanasiyana zapamwamba monga zida zopangira ndi ufa.

Kuchokera pakatentha kotentha kwazitsulo zazikuluzikulu, kutulutsa kotentha kwamakalata akuluakulu okhala ndi ma tubular, extrusion yozizira yazigawo zazing'ono kwambiri, kulimbitsa molunjika ndikuwumba kwa zinthu zopangidwa ndi ufa ndi tinthu tating'onoting'ono monga zinthu zopangira, kuzinthu zovuta kukonza zotere monga mankhwala ophatikizana komanso zida zopitilira muyeso, ukadaulo wamakono wa extrusion wakhala ukugwiritsidwa ntchito kwambiri.

Njira zopangira extrusion ndizabwino kwambiri za extrusion, reverse extrusion, lateral extrusion, glass lubrication extrusion, hydrostatic extrusion, extrusion.Extrusion processing imadziwika ndi kupsinjika kwamphamvu katatu, komwe kumathandizira kukonzanso kupindika kwa pulasitiki kwazitsulo, kukonza mtundu wa malonda, kukonza magwiridwe antchito amkati ndi magwiridwe antchito.

Kuphatikiza apo, kukonza kwa extrusion kumakhalanso ndi mitundu ingapo yamafunsidwe, kusinthasintha pakupanga, njira yosavuta komanso kugulitsa zida zochepa.

Ma alloys osakhala ndi fungo okhala ndi malo otsika osungunuka, monga aluminiyamu ndi alloys ya aluminiyamu, ndi zida zomwe amagwiritsidwa ntchito kwambiri mu processing extrusion.
