Silicone rubber molds ni hpe grai kaja ai hku n-gun ja ai-hpyen n-gun hpe hkam sharang lu ai, n-gun n-gun n-rawng ai, bai gram lajang lu ai atsam ni a majaw, lata hte galaw ai, tsi hpaji, electronic zawn re ai hpaga lam ni hta, arung arai ni hpe bai galaw shapraw ai hta grai lang ma ai.
Molding galaw ai lam hta madung hku nna ahkyak ai lahkam mali lawm ai: kayau kaya ai, n-gun n rawng ai, vulcanization galaw ai, hte post- galaw ai.
Langai, mixing gaw madung re. Silicone rubber hpe gaw, npawt nhpang rubber hpe, n-gun rawng ai baw langai hte, n-gun rawng ai 10:1 (sh) 1:1 hku nna, n-gun rawng ai baw langai hte kayau nna galaw ai. Mixing hpe n bung ai hku n byin hkra uniform galaw ra ai. Nkau mi gaw, n-gun n rawng ai silicone rubber hpe jai lang nna, kayau ngut ai hpang n-gun n rawng ai sha mai tsai wa nna, lawan ladan galaw na matu htuk manu ai.
Lahkawng, degassing galaw ai gaw, n-gup magap a quality hpe hkrak hkra machyi shangun ai. Mix galaw ngut ai hpang, silicone rubber hpe nbung n-gun hpe shapraw kau na matu (sh) nbung n-gun hpe shapraw kau na matu vacuum galaw ra ai. N rai yang, n-gun dat ngut ai hpang, n-gun dat hta nbung hka htung ni byin wa nna, n-gun dat hpe bai gram lajang lu ai atsam hpe shayawm ya lu ai. Vacuum degassing hpe -0.09 MPa hta minit 5-10 laman nbung n-gun yawng hpe shapraw kau ai aten du hkra galaw ai.
Vulcanization gaw madung lahkam re. Nta -katsi ai vulcanized silicone rubber hpe kayau ngut ai hpang shingra tara hku nna mai tsai wa ai, laksan hku nna hkying hkum loi mi kaw nna hkying hkum 24 laman, grup yin katsi ai hte catalyst a n-gun hta hkan nna mai tsai wa ai. Kaja ai hku galaw na matu, n-gun ja ai vulcanization (ga shadawn, 80-150℃hta minit law law hkru ai) gaw, n-gun ja ai aten hpe grai shayawm ya lu ai. Molding galaw ai shaloi, npawt nhpang n-gun (ga shadawn, wax (sh) resin mold) hpe n-gun n rawng ai plate langai mi hta ngang ngang jum da nna, silicone rubber hpe ru bang nna, n-gun n rawng hkra film langai mi hpe ka-up da ai.
Hpang jahtum, post- galaw ai hta trim galaw ai hte n-gun shaja ai lam ni lawm ai. Demolding galaw ngut ai hpang, mold jut ni hpe gang je kau nna, n-gun rawng hkra galaw ra ai. Hkrak ai npawt nhpang ni hpe n-gun grau jat wa na matu silicone rubber hte bai-hkap la mai ai. Nkau mi hta, n-gun grau law hkra shapraw na matu, n-gun dat hpe n-gun dat a ntsa de chya ya ai.
Silicone rubber molds ni gaw, n-gun rawng ai molding galaw ai ladat hpe jaw ya ai, manu hte hkrak ai lam hpe rap ra hkra galaw ya ai majaw, grai sawng ai shingnip shingna (sh) n-gun rawng ai arung arai ni hpe bai galaw na matu grau nna htuk manu ai. Material science hta rawt jat wa ai hte maren, n-gun ja ai-hkum hkrang n-gun ja ai silicone rubber gaw, n-gun ja ai hte myi prwi hpe n-hkap la lu ai, shi a jai lang ai shara ni hpe grau jat wa shangun na re.
