Liquion silicone rubber foaming arung arai ni a manghkang ni hpe hparan na matu, npawt nhpang hpe madung tawn nna, hkrang shapraw ai ladat ra ai.
Core philosophy: Makawp maga ai lam gaw sharai ai hta grau kaja ai. Manghkang law malawng gaw "masha, jak, arung arai, ladat, grup yin" a lam manga hta hkang lu ai atsam sum mat ai kaw na pru wa ai. Dai majaw, hparan ladat hpe mung ndai lam manga kaw na hkrang shapraw ai hku nna galaw ra ai.
Liquid silicone rubber foaming a matu hparan ladat gaw "formula" hte "process" lapran na hkrak ai rap ra lam hpe grau nna myit maju jung ai, grau nna foaming hte vulcanization lawan ai lam ni hpe shingdaw ai lam hpe grau nna myit maju jung ai.
一.Cell structure hte seng ai lam ni (n bung ai, hpaw nna pat da ai cell ratio, pore size)
1.Sign formula (material) - Ndai gaw ahkyak dik htum lahkam rai nga ai: Faming agent hte vulcanize agent: Chyam dinglik ai lam ni hku nna (DOE), foaming agent a decomposition temperature/ rate lapran na kaja dik htum shingdaw ai lam hpe tam u. Kaja dik ai masa gaw, bubbles ni jat wa hpang wa ai shaloi, rubber compound a viscosity gaw loi mi sha jat wa ai raitim, n-gun n rawng shi ai.
. Base adhesive a viscosity hpe gram lajang u: Htap htuk ai viscosity hpe lata u. Viscos grai law ai rai yang, bubble ni hpe hkai na matu yak na re; grai n law ai rai yang, bubbles ni gaw hpawng de chye ai.
2. Surface quality hte seng ai lam ni (roughness, skinning)
1.Mold temperature (method) hpe gram lajang ai : Ntsa kaw bubbles (sh) roughness nga ai rai yang: Dai mold temperature grai law ai majaw, npu na layer gaw foam hpe n-gun ja ai hte kalang ta byin shangun ai. Mold temperature hpe hkrak hkra jahkrat na matu shakut mai ai (sh) cold runner system hpe lang nna, rubber compound hpe n-gun n law ai shara hta n-gun dat shang wa hkra galaw mai ai.
2.N-gup a n-gun hpe hkam sharang u: Hkum hkrang n-gun byin ra ai shaloi, n-gup n-gu n-gun n-htum ai sha lawan ai hku n-gup n-gu hte matut mahkai lu na matu, n-gup n-gu n-gun grau tsaw ai hpe lang u. N-gun n rawng ai hte n-gun n rawng ai hkum hkrang ra ai shaloi, n-gun n law ai n-gun hpe lang u.
3,Density deviation hte shrinkage galai shai ai lam
. 60% kaw nna 80% daram hpe tsi htu ai n-gun a n-gun hpe jep joi ai lam ni hku nna hkrak hkrak chye lu na matu ra kadawn ai lam hpe hkrak tup chye na ra ai. Vulcanization aten hpe jat nna, dai arung arai a madung daw hpe mung hkum tsup ai hku n-gun dat nna, post{7}}}}} ai hpang na daw hpe shayawm ya lu na matu.
3.Ejection hte katsi ai (method, machine) : Product hpe demmold galaw ngut ai hpang, katsi ai a matu shaping fixture (fixture) hpe lang nna, n-gun n rawng ai hpe koi gam na matu. Ejector pin ni a shara hte n-gun hpe grau kaja hkra galaw u, dai hku nna, dai arung arai hpe n-gun atsam npu hta hkrak hkrak hte maren mara shapraw kau lu na matu.
