Production Process
Our production process ensures the highest quality standards through a series of meticulously controlled steps:
- Mixing: Ingredients are uniformly mixed in precise ratios.
- Melting: The mixture is heated to form a uniform glass liquid.
- Pressing: The glass shape is formed using a hydraulic machine.
- Tempering: Glass is cooled to achieve surface stress for durability.
- Cold and Hot Shock: Tests are conducted to ensure stability and low self-explosion rates.
- Glue Assembly: Components are assembled with precision to maintain structural integrity.
- Inspection: Rigorous testing ensures compliance with standard requirements.
- Packaging: Tailored packaging solutions meet customer needs worldwide.
