Heat-Resistant Industrial & Designer Lighting | Thermal Shock ΔT150°C
Industrial machine pressed glass lamp shade factory. Automated pressing delivers ±0.3mm dimensional repeatability across 10,000+ units. Tempered, alabaster & opal finishes. Hospitality & retail lighting solutions.
Technical note box: Complex shapes are achieved through the use of multi-part molds (3-6 part molds) with zero draft angle design, coupled with automatic demolding robots, ensuring the intact removal of thin-walled deep-cavity products.

Machine pressing utilizes H13 tool steel molds (Rockwell hardness 48-52 HRC) with automated glass gob weight control (±2%), pressing force 0.5-2.5MPa, and precision timing (15-45 second cycle) to achieve injection-molding-level repeatability in glass.

6 steps to cooperation
Standard MOQ 500pcs per design. Lead time 3-4 weeks including mold making (7-10 days for new designs). For 5,000+ units, 2-week express production available. Repeat orders: 1-2 weeks.
Three controls: (1) All glass from single furnace batch for orders <10,000pcs, (2) Inline spectrophotometer monitoring with automatic furnace chemistry adjustment, (3) Sample retention comparison for multi-batch large orders. Guaranteed ΔE<1.0.
Yes, our DFM team optimizes designs for pressing: adding draft angles (minimum 1°), uniforming wall thickness, simplifying undercuts. 90% of blown silhouettes can be adapted while maintaining 95% visual similarity at 40% lower cost.
Tempered (our standard): Surface compression >69MPa, breaks to small granules, 5-7× strength, 250°C max. Heat-strengthened: Surface compression 24-52MPa, breaks to larger pieces (not safety), 2× strength, 200°C max. We recommend tempered for all overhead/safety applications.
Mold cost $3,000-8,000 amortized over first order or paid upfront. Client-owned molds stored free for 2 years; exclusivity contract available preventing production for competitors. Mold modifications (size variants) at 30% of original cost.
Yes. Standard pressed glass handles 120°C continuous (adequate for LED). For high-lumen density COB arrays, specify our low-iron borosilicate-pressed option (300°C rating, +15% cost) or integrated heat sink interfaces.
Our pressing lines run 24/7 with 99.7% OEE (Overall Equipment Effectiveness). Every shade is laser-marked with batch code, linking to complete production data — furnace temperature, mold ID, operator, inspection results — for full traceability.
From raw glass selection to precision finishing, we control every step to deliver consistent and high-quality glass lamp shades.
