Ts'ebetso ea kenyelletso
3/4 ea lihlahisoa tse betliloeng tse entsoeng li etsoa ke extrusion e hlabang e butsoang. Ts'ebetso ea extrusion ke ho qobella thepa ho phunya lesoba kapa ho shoa ho etsa sehlahisoa.

Ts'ebetso ea ho betla ha extrusion e na le mehato e 5: 1. Preform ea polasetiki (extrusion ea tube ea polasetiki e sekoti). Koala hlobo e tlamang holima parison, ts'oara hlobo ebe o khaola parison. 3. Letsa hlobo leboteng le batang la sekoti, lokisa ho buloa le ho boloka khatello e itseng nakong ea pholileng. 4. Bula hlobo 'me u tlose likarolo tse phatlohileng. 5. Fokotsa khanya ho fumana sehlahisoa se felile.

Extrusion sekoti thulaganyou e bohloko bōpa
Extrusion sekoti bohloko bōpa ke ho qhibiliha le plasticize polasetiki ka extruder ka, 'me ka nako eo extrude e parison tubular ka shoa tubular. Ha parison e fihla bolelele bo itseng, parison e futhumatsoa ka hlobo ea moea. Moea o petelitsoeng o fehloa kahare ho etsa parison e haufi le lebota la sekoti sa hlobo ho fumana sebopeho sa mokoti, mme tlasa maemo a ho boloka khatello e itseng, kamora ho pholisa le ho bopa, sehlahisoa se fefiloeng se fumanoa ka ho thelisoa. Tshebetso ea extrusion bohloko bohloko ke tse latelang.
Polasetiki → polasetiki le extrusion → parison ea maqhubu → ho koaloa ha hlobo → ho thehoa ha theko ea litheko → ho phomola → ho bula hlobo
Motsoako oa likhahla tsa extrusion o ka aroloa ka methati e mehlano e latelang, joalo ka ha ho bonts'itsoe ho Setšoantšo sa 1-1.
① The polymer e qhibiliha ka extruder, 'me ho qhibiliha ho thehoa hore e be parison ea lefuba ka lefu.
Ha parison e fihla bolelele bo reriloeng esale pele, hlobo ea bohloko e koetsoe, parison e ts'oarelloa lipakeng tsa halofo tse peli tsa hlobo, 'me parison ea sehiloe ebe e isoa seteisheneng se seng.
Inject moea o petelitsoeng ka har'a parison ho kenya parison ho e atametsa mohahong oa hlobo ho theha.
④ Phola.
PBula hlobo 'me u ntše sehlahisoa se entsoeng.
