Manufacturing Process Overview & Flowchart

Raw Material Selection
(Sand, soda, limestone, industrial-grade cullet – ISO 14021)

→

Batch Melting
(Furnace 1500°C; EN 572 melt standards)

→

Pattern Rolling
(Molten glass passes between textured Nashiji rollers)

→

Annealing
(Stress removal, achieves uniform strength—ISO 12543-1)

→

CNC/Edge Finishing
(Precision shaping, holes, bevels, corner cut—CNC)

→

Final Quality Inspection
(Optical, impact, thickness—per EN 572-8; fully documented)

The above process is strictly monitored at each quality control stage. The raw composition (SiO2>72%) ensures inherent corrosion resistance and stable optical performance, while the Nashiji roller precisely imprints the signature raindrop pattern.

Key Technical Advantages:

Excellent pattern uniformity, which preserves privacy while optimizing daylighting.
High chemical stability for exposure to industrial fluids and atmospheric pollutants (critical in petrochemical and metallurgy sectors).
Superior edge quality via CNC, meeting flatness and dimensional tolerances (≤0.3mm deviation per meter).
Comprehensive batch testing—every sheet is tested for impact (ANSI Z97.1) and visual distortion (ISO 9050 transmittance).

Application Scenarios & Technical Advantages

Office partitions & privacy windows: Used extensively in modern workspaces, Nashiji pattern provides visual privacy while allowing high natural light, reducing dependence on artificial lighting by 15-24% per GlobalSpec Facade Glazing Study.
Sanitary partitions & shower enclosures: High mold/mildew resistance, easy to clean, superior privacy, and certified anti-slip matte quality.
Chemical, metallurgy & industrial sectors: Corrosion resistance and durability under fluctuating thermal/physical conditions (see application case below).
Residential & furniture: Used in cabinet/wardrobe doors, glass tabletops, display units—pattern maintains aesthetics while hiding clutter.
