Abstract
Description
2Dガラス板が金型100の上にある間に、成形温度、例えば、107ポアズから1011ポアズ(106Pa・秒から1010Pa・秒)のガラス粘度に対応する、またはガラスのアニール点と軟化点の間の、温度範囲にある温度に、2Dガラス板を加熱する工程を含む、一般的な熱再成形プロセス、
に用いることができる。加熱される2Dガラス板は加熱されると垂下し始めることができる。一般に、ガラス板を成形面122と共形にし、よってガラスを3Dガラス品に成形するため、次いでガラス板と金型100の間に真空が印加される。3Dガラス品の成形後、3Dガラス品は、3Dガラス品のハンドリングが可能になるであろう、ガラスの歪点より低い温度まで冷却される。
