Diagrama de fluxo do processo de fabricação de garrafas de vidro

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: Falando em geral, a fabricação de garrafas de vidro principalmente em quatro fases:

• (1) Preparation of raw material.
• The bulk raw materials (quartz sand, carbonato de sódio, limestone, feldspar, etc.) 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. Geralmente, 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.

A tecnologia de produção do vidro desde o início até a obtenção do produto final consiste em grandes investimentos e um profundo conhecimento das fórmulas químicas de fabricação. Para grandes empresas, esses são os requisitos básicos. É possível obter este material por meio de dois métodos: o processo Fourcault e o processo do vidro float. A tecnologia do processo Fourcault é baseada na laminação de massa de vidro quente através de rolos especialmente projetados.
