Manufacturing Process: Precision and Quality Assurance

The production of 3mm 4mm Nashiji obscure pattern glass involves a sophisticated sequence of steps, ensuring consistent quality and the distinctive 'pear skin' texture. The primary materials consist of high-quality silica sand, soda ash, limestone, and other raw ingredients, carefully selected for purity and specific melt characteristics. The process is a variation of the rolled glass method, meticulously controlled to meet international standards such as ISO 9001 for quality management.

Process Flow:

1. Raw Material Batching: Precise quantities of silica sand, soda ash, limestone, and cullet (recycled glass) are weighed, mixed, and fed into the furnace. This ensures the correct chemical composition for optimal glass properties.
2. Melting: The batch materials are melted in a high-temperature furnace (typically around 1500-1600°C) until a homogeneous molten glass mass is achieved. Energy efficiency is a key consideration at this stage, with advanced furnace designs minimizing fuel consumption.
3. Forming (Rolling): The molten glass flows from the furnace onto a casting bed, where it passes between two synchronized rollers. One roller is smooth, and the other has the Nashiji pattern engraved on its surface. This imprints the characteristic texture onto one side of the glass sheet, while the other side remains smooth. The thickness (3mm or 4mm) is precisely controlled by the gap between the rollers.
4. Annealing: The formed glass sheet enters an annealing lehr, a controlled cooling chamber. Here, the glass is slowly cooled from high temperatures to ambient temperature. This critical step relieves internal stresses that develop during rapid cooling, preventing breakage and enhancing the glass's mechanical strength and durability.
5. Cutting and Inspection: Once annealed, the continuous glass ribbon is cut into specific dimensions. Each sheet undergoes rigorous quality inspection for thickness, pattern consistency, visual defects (bubbles, stones, scratches), and overall optical quality. Compliance with standards like ANSI Z97.1 for safety glazing is verified.
6. Finishing and Packaging: Edges may be processed (e.g., seamed, polished) as per customer requirements. Finally, the glass sheets are cleaned, packed securely with interleaf material to prevent scratching, and prepared for shipment.
