Exquisite metal sole pad, high-strength wear resistance, corrosion resistance, practical and elegant.
Glassware production process:
①Pre-processing of raw materials. Crush the bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.) to dry the wet raw materials, and remove iron from the iron-containing raw materials to ensure the quality of the glass.
② Preparation of batch materials.
③Melting. The glass batch material is heated at high temperature (1550~1600 degrees) in a pool furnace or a pool furnace to form a uniform, bubble-free liquid glass that meets the molding requirements.
④Forming. Put the liquid glass into the mold to make glass products of the required shape, such as flat plates and various utensils.
⑤ Heat treatment. Through annealing, quenching and other processes, the internal stress, phase separation or crystallization of the glass is eliminated or generated, and the structural state of the glass is changed.
