Our production process
BO-GLASS specializes in customized glass molding services, offering end-to-end solutions from prototype development to mass production. Our China-based facility features a 10-ton daily capacity borosilicate glass furnace, in-house tempering ovens with high-pressure air quenching systems for rapid cooling, and comprehensive post-processing equipment including precision cutting, polishing, and grinding. We deliver high-quality glass components of any size or complexity, supported by expert technical guidance, optimized production workflows, and seamless design-to-manufacture transitions, ensuring efficient project execution with competitive pricing and tailored engineering solutions.
Mold pretreatment
Mold cleaning Soak the graphite mold in anhydrous ethanol for 10 minutes, ultrasonically clean for 5 minutes, and blow dry with compressed air. Use a spray gun to evenly spray boron nitride suspension (BN: ethanol = 1:10), and dry at 80°C for 1 hour to form a 20μm isolation layer.
Light transmission detection screening
Place the glass rod vertically in front of the light source and rotate 360° to observe the uniformity of light transmission. Rejection criteria: bubbles > 0.05mm, stones, stripe distortion. Marking and re-cutting: Mark the defective section with an oil pen, and retain the qualified part after cutting.
Cutting glass rods
Cut with a diamond scribing knife, The cut is polished with butane flame (1300°C instantaneous burning to eliminate microcracks).
Material quality inspection
It includes the uniformity of light transmittance of glass raw materials (bubbles, stones, streak defects), melting state (temperature fluctuations, softening sag), structural integrity after molding (cracks, thickness deviation), etc.
Melting of glass
Temperature control: Borosilicate glass: 820°C±5°C (monitored by infrared thermometer). Observe the softening state: the glass rod sags 3~5mm and is orange-red and translucent. Defoaming by rotation: The high-temperature resistant tweezers rotate at a constant speed of 2~3 rpm, and the axial temperature difference is ≤10°C/cm. If bubbles are found, immediately immerse it in a 600°C preheated graphite crucible and let it stand for defoaming.
Pressing and molding
The softened glass is transferred to the center of the mold within 5 seconds (the mold is preheated to 200°C). Prepress the auxiliary press (2MPa/5 seconds) for initial shaping. The hydraulic press pressurizes to 10MPa and maintains the pressure for 15 seconds (pressure error ±0.5MPa). The verticality of the pressure direction is ≤1° to avoid uneven thickness caused by eccentricity.
Initial inspection
Initial inspection is the first rapid quality inspection link after the glass is pressed and formed. It aims to screen appearance and basic structure defects through visual inspection and simple tools to prevent unqualified products from flowing into subsequent high-cost processes (such as annealing and grinding).
Annealing
The internal stress of the glass is eliminated through gradient cooling to prevent cracking or deformation caused by excessive cooling, thus ensuring the structural stability of the finished product.
Grinding
Precision grinding of edges or surfaces of molded glass parts to correct dimensional tolerances and improve optical surface flatness and appearance consistency.
Cleaning
Use ultrasonic cleaning process to remove residual particles, and after drying, use shock-proof and scratch-proof material to package to avoid damage during transportation and storage.

Materials
High Borosilicate 3.3 Glass Rods (e.g., Duran, Pyrex type):
Composition: Primarily silica (SiO₂ ≈ 80%) and boron trioxide (B₂O₃ ≈ 13%), with low alkali content.
Key Property: Exceptionally low coefficient of thermal expansion (CTE ~3.3 x 10⁻⁶/K).
Thermal Performance: Outstanding thermal shock resistance and high chemical durability. High strain point (~520°C).
Optical: Good transmission in the visible spectrum, suitable for many lens applications.
Processing Advantage: Low CTE ensures dimensional stability during the high-temperature pressing cycle and subsequent controlled annealing, critical for precision lens shape and minimizing stress-induced birefringence. Its viscosity-temperature profile allows effective flow into molds while maintaining shape integrity. Inherently resistant to weathering and many chemicals.
Exceptional Thermal Stability: Ultra-low CTE (~3.3×10⁻⁶/K) minimizes thermal stress during high-temperature pressing and annealing cycles, preventing cracking and ensuring dimensional accuracy.
Superior Stress Resistance: Inherently high resistance to thermal shock maintains optical homogeneity, critical for minimizing stress-induced birefringence in finished lenses.
Controlled Viscosity Flow: Optimal viscosity profile at pressing temperatures enables precise mold filling while retaining intricate shape definition post-pressing.
Chemical & Environmental Durability: High resistance to weathering, water, and chemicals ensures long-term lens clarity and performance stability.
Annealing Efficiency: Low CTE allows faster, more controlled annealing cycles without compromising lens integrity or inducing distortion.
Material Consistency: High purity and homogeneity contribute to predictable optical performance and reduced defects.
