Curing glass - tests
| |||
Procedure of samples takeoff to test impact resistance, resistance to thermal shock and tension measurements.
From the molding line after quality receiver we take away every hour 2 pieces glasses. The both pieces go for test impact resistance. Increased impact resistance we create by warming of the oral edge and its subsequent rapid cooled on the line Biebuyck.
