Plastic ni hpe galaw shapraw ai hta ahkyak ai ladat langai hku nna, blow molding hpaji masa gaw, arung arai ni hpe grau kaja hkra galaw shapraw ai hta ahkyak ai sha n-ga, dai ni na aten na hpaga lam hpe rawt jat galu kaba wa hkra, arung arai ni hpe atsawm sha jai lang lu hkra, engineering application ni a lamu ga jarit ni hpe jat wa hkra galaw ai hta ahkyak ai lit nga ai.
Materials science a ningmu hku yu yang, blow molding gaw gas pressure hpe lang nna, n-gun rawng ai plastic hpe maren mara n-gun rawng hkra galaw nna, n-gun rawng ai plastic hpe n-gun rawng ai daw langai mi byin shangun ai. Ndai ladat gaw polymer a rheological akyang lailen, n-gun rawng ai lam, molecular orientation ni lawm ai n-gun rawng ai lam ni a matu grai ahkyak ai lam ni nga ai. Ga shadawn, blow-up ratio hte cooling rate hpe hkrak hkrak hkang lu ai hku nna, dai arai a jak rung atsam hte nhtoi htoi ai hpe, bungli galaw ai shara amyu myu a ra kadawn ai lam ni hpe hkan nna, gram lajang lu ai. Dai hta n-ga, ndai hpaji masa gaw, non-equilibrium masa ni hta nga ai polymer arung arai ni a hkrang bung ai lam ni hpe hkaja na matu laklai ai chyam dinglik shara langai mi hpe jaw ya nna, dai arung arai ni a npawt nhpang matut mahkai lam ni hpe grau sung hkra chye na hkra karum ya nga ai.
Engineering application ni hta, blow-molded parts ni a n-gun n law ai shingra tara gaw, htaw sa ai n-gun lang ai lam hpe grai shayawm ya nna, hkai sun galaw shapraw ai lam a rawt jat galu kaba wa ai masa hte maren rai nga ai. Ga shadawn, mawdaw sau tank hte tsi mawan ni hpe shinggyin tawn ai tank zawn re ai laklai ai arung arai ni gaw, shanhte a n-gun kaba ai-to-hkum hkrang n-gun hpe, nbung n-gun n-gun jat ai lam a masat masa ni hpe hkrak hkrak hkang lu ai hku nna madun dan ai (temperature gradients hte mold geometry zawn re ai ni). Ndai lam gaw, coupled computational fluid dynamics hte thermodynamics shingdaw ai lam ni zawn re ai, hpaji amyu myu sawk sagawn ai lam ni hpe shadut ya nga ai. Dai hta n-ga, ndai hpaji masa gaw manu n law ai-, yak hkak ai shingnip shingna ni hpe hpawng de da ai hku galaw lu shangun nna, tsi mawan hte nbungli hpaji zawn re ai ginra ni hta ningnan ai hkrang shapraw ai lam ni a matu ahkaw ahkang nnan ni hpe hpaw ya lu ai.
Hkringmang daju a ningmu hku yu yang, blow molding gaw, n-gun n-gun hte n-gun jai lang ai lam hpe shayawm ai hku nna, circular economy ngu ai myit masa hpe hkrang shapraw ya ai. Hpaji ninghkring ni gaw, grup yin hpe grau nna akyu jaw lu na matu, bio-based plastics hte bai jai lang mai ai arung arai ni a matu blow molding ladat ni hpe gyin shalat nga ai.
Tsun ga nga yang, blow molded parts ni gaw, hpaga lam hta galaw shapraw ai arung arai ni sha n-ga, arung arai hpaji, engineering, grup yin makawp maga lam ni hpe matut mahkai ya ai hub langai mung rai nga ai. Shanhte a hpaji masa manu gaw hpaji hparat hpaji ningnan ni hte matut nna sung wa nga ai.
