Process of curved glass for appliances: Empowering the Texture and Performance Innovation of High-end Home Appliances

Introduction:

Amid the wave of consumption upgrading and home appliance intelligence, appearance texture and functional practicality have become the core competitiveness of high-end home appliances. Shunde Dehong Glass Industry Co., Ltd. focuses on making the curved glass for kitchen appliances and has been providing the glass products that boast both artistic and durable characteristics through precise craftsmanship. The company gives design vigor and quality assurance to the kitchen appliance products such as refrigerators, ovens, and gas stoves.

What is Hot Bent Glass?

Hot Bent Glass: It was developed through the process of heating a flat glass in order to make it malleable. This glass was bent into a particular shape through a special mold as it was cooled. This is one of the fundamental categories of heat bent glass. Hot bent glass can be classified into cylindrical bent glass, single bent glass, compound bent glass, and a few others that are able to achieve specific radiums depending upon the needs of home appliances. Hot bent glass has a great capability in comparison to normal glass as it not only has a smoothed appearance but also has optimized product holding as well as adaptability in space. It also has a very efficient capability concerning optical transparency as well as a stronger ability for structural integrity. The major parameters include Curvature Tolerance and Optical Distortion.

The Process of Curved Glass

The production technology of hot bent glass involves a sophisticated and normalized procedure. In this regard, the first procedure involves the cutting and grinding of raw glass. This requires the use of high-purity soda lime silica glasses or high-aluminum silicate glasses. In this next procedure, it is necessary to cut the glasses using CNC Cutting equipment. Next, there is fine grinding.The second step is cleaning and drying: use high-pressure spray and ultrasonic cleaning technology to thoroughly remove oil, dust and other impurities on the glass surface, then dry at high temperature to ensure no water marks on the surface, avoiding affecting the hot bending effect. The third step is high-temperature hot bending forming: send the glass into a continuous hot bending furnace, heat it to 600-700℃ to soften it, then fit the custom mold for natural forming or pressure shaping. Precisely adjust the heating and cooling rate through an intelligent temperature control system to ensure uniform radian and flat curved surface, avoiding mold marks or twist deformation. The fourth step is tempering strengthening treatment: the formed hot bent glass quickly enters a quenching chamber, and tempering is realized through upper and lower convection air cooling, so that the glass surface forms uniform compressive stress and the interior generates tensile stress, greatly improving impact resistance and thermal shock resistance. The final step is quality inspection and post-processing: use laser scanning method to detect curved surface deviation, combined with manual re-inspection of appearance defects. At the same time, screen printing, Anti-Fingerprint Coating, electromagnetic shielding film lamination and other post-processing can be carried out according to requirements to meet the functional and appearance needs of home appliances.

Advantages

The core advantages of hot bent glass are precisely matched to the usage scenarios and high-end positioning of kitchen appliances. Firstly, excellent structural performance: after tempering, the impact resistance is 3-5 times that of ordinary glass, and the maximum heat resistance temperature can reach more than 450℃, which can withstand long-term high-temperature operation and daily collision of kitchen appliances. It breaks into obtuse small particles, ensuring higher safety. Secondly, high-end aesthetic value: the smooth curved lines break the monotony of flat design, can adapt to embedded and integrated kitchen styles, enhance the recognition and texture of home appliance products, and become an important carrier for brand differentiated competition. Thirdly, diversified functional integration: it can be compatible with screen printing shielding, touch sensing, ultraviolet blocking and other functions, which can not only meet the signal transmission needs of home appliance control panels, but also realize personalized appearance customization. Fourthly, easy cleaning and durability: the surface is dense and smooth, combined with anti-fingerprint coating, oil stains and dirt can be easily wiped, and it is not easy to scratch and age after long-term use, with low maintenance cost. Fifthly, precision customization capability: according to the needs of home appliance manufacturers, products with different radians, thicknesses and colors can be customized to adapt to the design needs of various scenarios such as refrigerator panels, oven doors and stove tops.

Application Range

The application scenarios of hot bent glass have fully covered the core categories of kitchen appliances, becoming a standard component of high-end products. In the field of ovens and steam ovens, hot bent glass is used for door panels, which can not only withstand high-temperature baking, but also facilitate users to observe the cooking state through excellent light transmittance. Combined with a multi-layer composite structure, it can also improve heat insulation performance and reduce heat loss. On stoves and induction cookers, the curved glass countertop is designed in line with ergonomics, easy to clean and beautiful in shape. At the same time, it has scratch-resistant, high-temperature resistant and impact-resistant characteristics, adapting to different cooking environments. In refrigerators and freezers, hot bent glass can be used for door panels or shelves, which not only improves the product appearance grade, but also achieves cold storage and anti-condensation effects through functional coatings, optimizing energy consumption performance. In addition, on small household appliances such as dishwashers and microwave ovens, the curved glass panel can integrate into the home design style, while meeting the functional needs of touch operation and safety protection, bringing users a better experience. In the future, with the development of smart home appliances, hot bent glass will be deeply integrated with sensors and display panels, expanding more application scenarios.

As a comprehensive glass processing enterprise, Dehong Glass has always adhered to the philosophy of "quality as the foundation and innovation as the core". Its products cover various kitchen appliance scenarios such as smart integrated stoves, embedded steam ovens, range hoods and dishwashers, providing global customers with one-stop solutions from customized design, process R&D to mass production. In the future, we will continue to focus on the directions of thinning, multi-functional integration and customized design, and use more advanced process technology to promote the transformation of home appliance arc glass from structural parts to comprehensive components integrating aesthetics, functions and intelligent interaction.
