Heavy Cast Decorative Lighting | 3D Relief Patterns | Luxury Hospitality OEM
Premium centrifugal cast glass lamp shade manufacturer. 1050°C molten pour, 800-1200 RPM precision casting. Deep 3D relief, jewel-tone colors, 2-8kg heirloom quality. Custom molds for luxury hotels & heritage restoration.
Mold Engineering: Complex 3D reliefs are carved using CNC-engraved aluminum molds or hand-carved cast iron molds, with surfaces plated with chromium to extend the lifespan to over 2000 cycles. Before each mold is used, a boron nitride release agent is applied to ensure complete transfer of the pattern.

Centrifugal force doesn’t just shape glass — it compacts it. Molecular density increases, bubbles vanish, and patterns emerge with jewel-like depth impossible in blown or pressed methods. This is gravity-defying mass, frozen in light.

Centrifugal casting exploits rotational force (F=mω²r) to drive molten glass into mold cavities at 5-10× atmospheric pressure. This force compaction eliminates bubbles, captures micro-detail, and creates radial symmetry perfect for floral, geometric, and figurative relief patterns.
6 steps to cooperation
Three factors: (1) Mold cost $5,000-15,000 vs $500-3,000 for other methods, (2) Cycle time 10-15 minutes vs 30-45 seconds for pressing, (3) Material usage 2-8kg vs 0.2-1kg. However, for patterns >2mm depth or weights >1kg, centrifugal is the only viable method. Amortized over 500+ units, per-piece cost becomes competitive.
Standard 3-5mm depth for clear definition. Maximum 8mm possible but increases wall thickness to 10mm+ and weight proportionally. Deep undercuts (>90°) require multi-part molds and show seam lines.
Yes, but thermal management critical. Dense glass (4-10mm) insulates well — LED heat must dissipate through fixture housing, not shade. We design integrated heat sinks or specify low-heat COB modules. Surface temp must stay <80°C for annealed glass.
We maintain a library of 200+ historical color formulations. For unique matches, we perform spectrophotometry on original samples and custom-batch glass. Success rate 95%+ for colors; mercury glass effects require artistic hand-spraying for authentic variation.
Practical limit Φ400mm/8kg for handling safety. Larger designs use segmented construction — multiple cast sections joined with hidden metal hardware or UV-cured optical adhesive. Record: Φ1.2m chandelier assembled from 8 cast petals.
Glass hardness 5.5 Mohs — patterns are permanent and wear-resistant. However, deep relief can collect dust; we recommend annual compressed air cleaning. For high-touch areas (table lamps), specify smooth surfaces or shallow texture.
The 72-hour annealing is non-negotiable. Centrifugal force compacts glass at molecular level — without stress relief, these dense shades would self-destruct months later. We wait so your grandchildren inherit functional art.
CNC aluminum mold or handmade cast iron mold, with chrome plating on the surface and boron nitride spraying
The tank furnace is at 1550°C, with the colorant homogenized, and the material is discharged at 1050°C
Inject a fixed amount of molten glass (2-8kg) into the center of the rotating mold
Spin at 800-1200 RPM for 30-90 seconds to compact the glass using centrifugal force
Slow down the rotation and cool it down to 600°C with air cooling, then open the mold
Maintain at 560°C for 72 hours to eliminate stress
