3. Manufacturing Process of 3mm 4mm Nashiji obscure pattern glass

Nashiji Obscure Pattern Glass Manufacturing Flow

Raw Silica Sand + Flux → Batch Melting
(>1600℃, soda-lime-silicate formation) → Pattern Rolling
(Casting on Nashiji Rollers) → Annealing
(Stress relief in lehr) → Cut-to-Size / Edgework → Inspection & Testing
(ISO/ANSI standard) → Packing & Logistics

Each stage is monitored by automated sensors for thickness, pattern depth, and surface defects.
Testing covers glass optical, mechanical, and chemical stability in accordance with ISO 12543, ANSI Z97.1, and EN 572-5.

Key Features from a Technical Perspective

Material: High-purity soda-lime glass, with patterned surface etched via precision rolling for Nashiji obscure effect.
Pattern Consistency: Modern CNC-controlled rollers ensure raw Nashiji texture depth between 0.18-0.35mm, securing consistent diffusion of light and privacy.
Quality Control: Laser and camera inspection for surface wave, thickness, bubble, and pattern distribution.
Certification: Regular audits to ISO 12543, ANSI Z97.1, EN 572-5.
Resistance: Nashiji glass achieves superior weathering resistance, with testing showing color and structure stability after 1,500h accelerated weather exposure.
Service Life: 15~30 years in typical outdoor/indoor architectural use, as verified by third party SGS testing.

5. Custom Solutions & Typical Application Scenarios

Customization is a core competence of modern manufacturers for 3mm 4mm Nashiji obscure pattern glass. Solutions can be tailored in terms of dimension (cut-to-size, oversized), pattern density, tint, colored films, and even in-laminate assembly for safety. Edgework (arrissed, polished, beveled) and toughening/lamination options further empower project requirements.

Project Type: Residential (windows, bathroom partitions, glass doors), Commercial Buildings (offices, hotels, malls), Industrial Glazing (factory partitions, laboratory view panels), Water Treatment Facilities (chemical-resistant panels).
Case Example 1: Shanghai Pudong Hospital (2023) used 5,200m² of 4mm Nashiji obscure glass in lab partitions, ensuring high light throughput and chemical resistance.
Case Example 2: Zhejiang Petrochemical Plant (2022) - 3mm Nashiji employed for control room windowing, offering privacy + 25% less UV transmittance vs. standard patterned glass.
