Precision Thermoformed Lighting | Shallow Profile Wall & Ceiling Solutions | OEM/ODM
Custom curved glass lamp shade manufacturer. CNC thermal forming 650-720°C, shallow profile 15-40mm depth. Uniform light diffusion for wall sconces, flush mounts & architectural lighting. Fire-polished edges.
Hot bending process control: The temperature gradient in the infrared heating zone is maintained at ±5°C to prevent optical distortion. For large curvature (R<150mm), vacuum suction molding is used to assist in forming, ensuring precision in fitting the mold.

When ceiling height is precious and clean lines are sacred, curved glass transforms two-dimensional sheets into three-dimensional luminaires. Zero visual weight, maximum luminous impact.

Thermal forming (heat slumping) utilizes CNC-controlled infrared heating zones to soften glass to plastic state (viscosity 10⁷·⁶ poise) at 650-720°C, then gravity-sag or vacuum-form over precision ceramic molds. Controlled cooling preserves optical clarity while locking curvature within ±0.5mm tolerance.
6 steps to cooperation
Practical minimum 15mm depth for Φ200mm diameter (R≈300mm). Shallower profiles risk spring-back and optical distortion. For <15mm, consider flat edge-lit panels (different technology, not true curved glass).
Annealed curved glass retains base material strength. For safety-critical applications, we post-temper after forming (curved tempered), achieving 5× strength with maintained curvature (±1mm tolerance relaxation).
Yes. We reverse-engineer ceiling radius from site templates or 3D scans, then CNC machine matching ceramic molds. Tolerance ±2mm over 600mm span. For compound curves (saddle shapes), vacuum forming enables 3D contouring.
Three strategies: (1) Thickness increase to 4-5mm for >Φ400mm, (2) Ribbed or stepped reinforcement on hidden surface, (3) Tempering for structural rigidity. Engineering consultation included for >Φ500mm designs.
Yes with proper edge sealing. Our fire-polished rims with silicone gasket achieve IP44 (splashing water). For IP65 (jets), specify laminated curved glass or additional frame sealing. Not recommended for submersion.
Annealed: 2000×1000mm (limited by kiln size). Tempered: 1200×600mm (quench uniformity limit). Larger areas use butt-jointed multiple pieces with optical-grade UV adhesive (seam nearly invisible when lit).
The magic happens in the thermal gradient — too hot, glass flows and thins; too cold, it resists and springs back. Our CNC zone control maintains the 50°C sweet spot across 600mm spans, achieving curvature accuracy impossible in manual kilns.
