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.
Preparation of glass raw materials and tube drawing
Quartz sand, soda ash, borax, and other raw materials are mixed in precise proportions based on the product's desired chemical properties (such as heat resistance and coefficient of expansion). The mixture is then melted into a uniform molten glass in a furnace at temperatures exceeding 1500°C. Advanced tube drawing or blowing equipment then controls the molten glass into straight tube billets of a specific diameter, wall thickness, and length.
Hot working shaping of pipe nozzle
A specially designed blowtorch flame is used to locally rotate and heat the end of the glass tube, softening it to a molten state. The operator then, relying on their experience, finely processes the inner and outer diameters of the tube mouth to the target dimensions by blowing air, using flaring tools, or relying on the glass's own gravity, preparing it for subsequent connection operations.
Uniformly heat and soften the entire tube
The section of glass tube to be bent is smoothly fed into a dedicated heating furnace or heated evenly and slowly over a flame of a row of lamps. This process softens the entire glass to a bright red, viscous, fluid state, achieving optimal plasticity and laying the foundation for the next step of bending and shaping.
Bending and shaping in the mold
Glass that has undergone heat bending accumulates significant internal stress. The formed part must immediately be placed in a precision annealing furnace, where it undergoes a strictly controlled thermal cycle of "heating-holding-slow cooling" to thoroughly and evenly eliminate this internal stress. This is crucial for ensuring the product's structural stability and preventing future spontaneous cracking.

Perform anti-static treatment
Glass is an excellent insulator, but it's susceptible to static electricity generated by friction, which can attract dust. For applications requiring cleanliness (such as optical instruments and semiconductor devices), glass is coated with a transparent antistatic coating or manufactured using conductive glass containing metal filaments to meet the specific needs of the environment.
Final quality inspection
The core of quality inspection is to use a polarizing stress meter to conduct a comprehensive scan to ensure that there are no residual stress points; secondly, dimensional accuracy, bending angles and appearance defects (such as bubbles, stones, and cracks) are strictly checked.
Protective packaging
Qualified products will be packed in protective boxes with independent slots to ensure that each product will not be collided during transportation and is delivered safely to customers.

Materials
High Borosilicate Glass Tubing (COE 33):
Composition: Primarily silica (≈80%) and boron trioxide (≈13%), with minimal alkali content.
Key Properties: Exceptionally low coefficient of thermal expansion (CTE ~33 x 10⁻⁷/K). This grants outstanding thermal shock resistance.
Processing: Specifically designed for direct flame working (“lampworking”). Its low CTE allows rapid, localized heating and cooling without cracking, enabling complex shaping.
Performance: Highly resistant to thermal stress, chemicals, and thermal cycling. Maintains clarity and structural integrity under temperature changes.
Result: Ideal for precisely forming intricate, durable glass lampshades via flame manipulation, as it can withstand significant thermal gradients during shaping. Its surface is inherently smooth.
Material Advantages:
Exceptional Thermal Shock Resistance: The low coefficient of thermal expansion (COE ~33) enables rapid, localized heating and cooling with the torch without cracking, crucial for detailed manipulation and assembly.
High Working Temperature Stability: Maintains viscosity and shape integrity at flame-working temperatures, allowing precise control over forming.
Superior Mechanical Strength & Durability: Results in thinner, lighter, yet highly robust lampshades resistant to breakage and thermal stress during use.
Chemical & Thermal Resilience: Highly resistant to water, chemicals, and thermal cycling, ensuring long-term clarity and performance in lighting applications.
Inherently Smooth Surface: Delivers excellent optical clarity without requiring extensive surface finishing post-working.
