Plastic extruders ni gaw plastic ni hpe galaw ai bungli hta madung arung arai ni rai nna, plastic arung arai ni hpe galaw shapraw ai hta grai law hkra jai lang ai, pipe, profile, sumla hkrung, wire hte cable insulation zawn re ai ni hpe galaw shapraw ai hta grai law hkra jai lang ai. Shanhte a bungli galaw ai npawt tara gaw, n-gun ja ai plastic raw materials (granules (sh) powder zawn re ai) hpe shinggrup nna, shinggrup ai screw kaw na pru wa ai katsi ai hte n-gun atsam hku nna, n-gun ja ai hku nna, hkrang langai a akyu hpe shabyin ya na matu, matut manoi shapraw kau na matu re.
Plastic extruders ni gaw madung hku nna ahkyak ai daw masum lawm ai: extrusion system, drive system, hte katsi ai hte katsi ai ladat. Hopper, screw, barrel ni lawm ai extrusion system gaw, dai arung arai ni a madung rai nga ai. Plastic raw material gaw hopper kaw na barrel kata de shang nna, shinggrup ai screw hte shawng de htawt sit ya ai, plastic hpe barrel shinggan kaw nga ai katsi ai jak hte loi loi hte htum mat ai. Screw design gaw plasticizing effect hte galaw shapraw ai atsam hpe hkrak hkra machyi shangun ai. Common screw amyu ni hta, n bung ai plastic raw materials hte process ra ai lam ni a matu htuk manu ai, kalang ta bai galai shai ai lam, akajawng sha- galai shai ai lam, garan ginhka ai lam ni lawm ai. Drive system gaw screw rotation a matu ra ai n-gun hpe jaw ya nna, n-gun n-gun, shayawm ai, bearings ni lawm ai majaw, n-gun rawng ai screw speed hpe hkam la lu ai. Hka lum ai hte katsi ai ladat gaw, barrel a nbung katsi ai hpe hkrak sha hkang lu ai, grai katsi ai hte hten za ai hpe pat shingdang ai sha n-ga, kaja dik htum plastic hka lim ai hpe hkam la lu ai.
Plastic extruders ni hpe single{0}}screw, twin-screw, hte shanhte a application hta hkan nna, multi{2}}screw ni hku nna garan ginhka mai ai. Single-screw extruders ni gaw, asan sha re ai hkrang hte manu n law ai, general-}hkawm plastic law malawng hpe galaw na matu htuk manu ai. Twin-screw extruders ni hpe shanhte a jat jat ai kayau kaya ai atsam hte, n-gun ja ai- n-pre ai lam ni a matu jai lang chye ai, dai ni gaw, n-gun ja ai, galai shai ai, jahpring ai, n-gun rawng ai lam ni hpe galaw ai. Multi-}screw ni hpe madung hku nna laksan polymer arung arai ni hpe galaw na matu lang ai. Dai hta n-ga, dai ni na aten na extruder ni hpe gaw, n-gun, n-gun, lawan ai lam zawn re ai parameter ni hpe hkrak hkrak gram lajang lu ai, galaw shapraw ai atsam hte product quality zawn re ai parameter ni hpe hkrak hkrak gram lajang lu ai.
Plastic extruders ni gaw gawgap ai lam, mawdaw, tsi hpaji, hte shinggyin la ai bungli ni hta ahkyak ai lit nga ai. Ga shadawn, PVC pipe extruder ni hpe hka hte hka lim ai pipe ni hpe shapraw na matu lang nna, n-gun n rawng ai sumla hkrung extruder ni hpe lang nna malu masha shinggyin ai sumla hkrung ni hpe galaw shapraw ai. Hkringmang daju gaw, grup yin hpe makawp maga ai lam hte n-gun atsam hpe makawp maga ai lam, akyu rawng ai lam hte n-gun atsam hpe makawp maga ai lam, n-gun atsam hpe makawp maga na matu ra sharawng ai lam ni law wa ai hte maren, hpaji masa hte hkrak tup ai lam de plastic galaw shapraw ai lam hpe shabyin ya nga ai.
