Blow molding ngu ai gaw plastic galaw ai bungli hta grai lang ai galaw shapraw ai ladat langai rai nga ai. Katsi ai plastic parison hpe n-gun dat langai hta bang nna, n-gun dat a kata na bunghku ni hte maren byin hkra, nbung hpe lang nna n-gun dat dat ai. Hpang jahtum, katsi mat nna, n-gun n rawng ai daw langai byin wa ai. Ndai ladat gaw, akyu rawng ai, n-gun rawng ai, manu jahpu-htuk manu ai zawn re ai akyu ni hpe jaw ya ai majaw, bungli amyu myu hta hollow plastic daw ni hpe galaw shapraw na matu htuk manu ai.
Hpaga lam hta, blow moulded parts ni hpe, tsi mawan barrel, sau tank, nli gat ai tsi ntsin htung zawn re ai, shingbyi shara hte htaw sa ai arung arai amyu myu hpe galaw shapraw na matu grai lang ma ai. Ndai arung arai ni gaw, laksan hku nna, n-gun ja ai tsi mawan ni hpe ninghkap lu ai atsam hte npawt nhpang n-gun ja ai lam ni hpe ra sharawng ai majaw, n-gun ja ai-polyethylene (HDPE) shing nrai, polypropylene (PP) zawn re ai arung arai ni kaw na galaw shapraw chye ai. Blow molding hpaji masa hku nna, wan sau tank, hka tank, hpaga lam hta hka htung ni hpe shinggyin tawn da ai hka htung ni zawn re ai, liter loi mi kaw nna cubic meter law law du hkra kaba ai hka htung ni hpe mung galaw lu nna, hpaga lam amyu myu a ra kadawn ai lam ni hpe hkap la lu ai.
Blow molded parts ni hpe mung, masha lang ai arung arai ni a gat lawk hta grai lang ma ai. Ga shadawn, plastic ntsin htung (mineral hka ntsin htung hte lu sha ntsin htung zawn re ai) ni gaw, blow moulded galaw ai arung arai ni hta grau nna lang ai. Dai ni hpe PET (polyethylene terephthalate) hte galaw ai rai nna, dai gaw grai kaja ai nsam hte n-gun rawng ai atsam ni hpe jaw ya ai. Blow molding hpe mung, ginsup hpa ni, ginsup arung arai ni (float hte ball zawn re ai), nta kata lang ai hka htung ni (laundry detergent bottles hte cosmetic bottles zawn re ai) ni hpe galaw shapraw ai hta mung grai lang ma ai, hpa majaw nga yang, dai gaw grai sawng ai hkrang ni hpe lu la nna, galaw shapraw ai atsam grai law ai majaw re.
Blow molding hpaji hpe mawdaw hte tsi hpaji zawn re ai high-end sector ni hta mung jai lang mai ai. Mawdaw hpaga lam hta, blow molded parts ni hpe lang nna, nbung n-gun, sau htu ai shara, instrument panel nta ni zawn re ai n-gun n law ai arung arai ni hpe galaw lu ai majaw, mawdaw a n-gun hpe shayawm ya lu nna, sau hpe mung grau kaja hkra jai lang lu ai. Tsi hpaji hta, blow molding hpe lang nna, n-gun n rawng ai ntsin htung ni hte tsi mawan ni hpe shinggyin tawn da ai ntsin htung ni hpe galaw shapraw ai rai nna, shim lum lam hte san seng lam hpe hkamja lam a matu tsi hpaji-grade madang ni hte maren rai ra ai arung arai ni ra ai.
Material science hte mold hpaji masa ni rawt jat wa ai hte maren, blow molding application ni a shingdu labau gaw matut nna jat wa nga ai. Htawm hpang de, ndai ladat gaw grau dam lada ai hpaga lam ni hta ahkyak ai lit hpe gun hpai na re, grau nna grup yin hpe makawp maga ai lam, n-gun n law ai lam, hte -htuk manu ai hku galaw shapraw ai lam ni hta grau kaba ai atsam hpe madun dan na re.
