Heat Bending Glass

Heat Bending Glass is manufactured by heating flat glass until it becomes soft, bending it over a customized mold, and then cooling it naturally to achieve the desired shape. This process allows seamless creation of single-curved, double-curved, and complex 3D forms, making it widely used in furniture, interior decoration, and home appliances.

Heat Bending Glass (Curved Annealed Glass)

Custom-formed glass solutions for interior, furniture, and decorative applications.

Heat Bending Glass is manufactured by heating flat glass until it becomes soft, bending it over a customized mold, and then cooling it naturally to achieve the desired shape. This process allows seamless creation of single-curved, double-curved, and complex 3D forms, making it widely used in furniture, interior decoration, and home appliances.

Unlike tempered curved glass, heat-bent glass remains annealed after forming. It offers excellent formability and aesthetic flexibility, but lower strength and safety performance — suitable for applications without strict safety or impact requirements.

Heat Bending VS. Tempered Curved Glass (Quick Comparison)

Characteristic	Heat Bending Glass	Tempered Curved Glass
Core Process	Heating → Mold Bending → Slow Cooling (annealing)	Heating → Mold Bending → Rapid Cooling (tempering)
Nature	Ordinary annealed glass	Safety glass
Strength	Same as normal glass, lower strength	3–5× stronger, high impact resistance
Safety	Breaks into sharp pieces	Breaks into small safe particles
Thermal Stability	Weak, sensitive to heat stress	Excellent, withstands high temperature differences
Spontaneous Breakage	No	Very low probability (~0.3%)
Applications	Furniture, décor, appliances	Facades, skylights, balustrades, structural glazing
Cost	Lower	Higher

Art and Sculptures

Architectural Art: Curved glass can be integrated into architectural art pieces to provide a dynamic and futuristic look.

Retail and Commercial Displays

Point of Sale Displays: Retail stores often use curved glass in point-of-sale displays to draw attention and create an elegant, high-end look.
Storefronts and Showcases: Curved glass is frequently used in storefront windows or product showcases, enhancing product visibility and the overall design of the store.

Manufacturing Process

Raw Glass Preparation
Cutting, edging, and chamfering the selected glass to avoid edge stress.
Mold Fabrication
Customized steel or ceramic molds built according to single curve, double curve, or complex shapes.
Heating & Softening
Glass is heated gradually to 600–650°C until soft enough for forming.
Bending & Forming
The glass conforms to the mold by gravity or controlled mechanical force.
Cooling & Annealing
Slow cooling eliminates internal stress; tempered versions undergo rapid cooling for strengthening.
Post-processing
Cleaning, inspection, and optional second-stage processes (laminating, coating, printing, etc.).

Q: What specifications do I need to provide when customizing curved glass?

A: You need to clarify four key details: ① Bending radius (critical for shaping complexity, especially for small-radius designs); ② Exact dimensions (must match your design drawings, with standard size range 150×150mm–12000×3600mm); ③ Thickness (4mm–12mm is common, selected based on scenarios like building facades or furniture); ④ Glass type (e.g., tempered, laminated, Low-E glass) as per usage needs.

Q: What is the delivery time for curved glass, and can it be expedited?

A: The standard delivery time is 7 days. Expedited service is available for urgent projects, but the specific timeline depends on your order quantity, customization complexity (e.g., double-curvature designs), and production schedule.

Q:What surface treatments and coatings are available for curved glass?

A: Common options include: ① Edge treatments (flat, rounded, beveled); ② Decorative finishes (sandblasting for matte effects, brushed textures); ③ Functional coatings (UV protection, anti-reflective, self-cleaning); ④ Drilling (for mounting/installation). Custom treatments can be requested based on your design needs.
