Flussdiagramm für den Herstellungsprozess von Glasflaschen

The production process of glass bottles includes raw material preparation, melting, molding, cooling annealing, surface treatment and testing. The raw materials are dried and melted into molten glass, which is made into glass bottles through molding technology. Cooling annealing improves stability, and finally surface treatment and quality inspection are carried out. Each step is strictly controlled to ensure high-quality products. The main process is as follows: Im Allgemeinen, Die Herstellung von Glasflaschen erfolgt hauptsächlich in vier Phasen:

• (1) Preparation of raw material.
• The bulk raw materials (quartz sand, Soda, limestone, feldspar, usw.) are crushed, the wet raw materials are dried, and the iron-containing raw materials are deironed to ensure the quality of the glass.
• (2) Melting in a furnace.
• The glass material is heated at high temperature (1550~1600 degrees) in a pool kiln or pool furnace to form a uniform, bubble-free liquid glass that meets the molding requirements.
• 
• (3) Forming by molds.
• Liquid glass is placed in a mold to make glass products of the desired shape. Generally, the preform is formed first, and then the preform is formed into a bottle body.
• (4) Finishing into packing.
• Through annealing, quenching and other processes, the stress, phase separation or crystallization inside the glass can be cleared or generated, and the structural state of the glass can be changed.
• 

Die Technologie der Glasproduktion vom Anfang bis zum Erhalt des Endprodukts besteht aus großen Investitionen und einer gründlichen Kenntnis der chemischen Formeln der Herstellung. Für große Unternehmen, Das sind die Grundvoraussetzungen. Dieses Material kann auf zwei Arten gewonnen werden: das Fourcault-Verfahren und das Floatglasverfahren. Die Technologie des Fourcault-Verfahrens basiert auf dem Rollen heißer Glasmasse durch speziell entwickelte Walzen.
