YHB has adopted a "intelligence plus manual work" dual quality assurance system for its sorting process, establishing a strict quality line. Relying on advanced image recognition technology, the automated visual crystal inspection machine conducts multiple rounds of scanning and inspection on products with micron-level precision, enabling it to quickly detect subtle issues such as dimensional deviations and surface defects. In the manual inspection stage, experienced quality inspectors, with their keen eyes and professional judgment, carry out in-depth screening of the blind spots in equipment detection. The complementary advantages of machines and manual labor have realized full-process and all-round quality control, providing each product with "dual quality insurance".
YHB products uphold their environmental commitment with rigorous standards and have successfully obtained the internationally authoritative OEKO-TEX® 100 certification, building a reassuring green barrier for users. This certification involves strict testing throughout the entire supply chain, from raw materials to finished products, ensuring that the products are free from over 100 types of harmful substances such as formaldehyde and allergenic dyes. It even conducts in-depth verification of the contact safety level required for baby and children's products.
Every YHB product that passes this certification signifies that it has reached the world's top standards in terms of ecological safety and human compatibility. Whether it is fabrics for close-to-skin use or products for daily contact, all of them feature the eco-friendly attribute of "direct skin contact". This allows users to enjoy quality while embracing a safe and healthy lifestyle with confidence.
YHB products empower craftsmanship with technology. Through the precise collaboration of automatic cutting and polishing machines and advanced numerical control (NC) technology, each drill is endowed with the "soul of gem-grade quality".
Equipped with a micro-scale servo system, the automatic cutting and polishing machine performs 360° three-dimensional carving on the drill body based on diamond-grade cutting principles. From the blank to the finished product, it undergoes precise polishing through dozens of processes. Meanwhile, the advanced NC system, with nano-level control precision, calibrates the cutting angle and polishing force in real time, ensuring that every facet conforms to the golden ratio of optical refraction.
The drill body created by this ultimate craftsmanship boasts cutting facets comparable to natural gemstones - the edge lines are as sharp as if carved with a knife, and the curved surfaces are as smooth as a mirror. Each cut surface is calculated through optical simulation, enabling perfect fire refraction when light enters. When light passes over the drill body, the radiance it emits meets gem-grade standards: it not only presents brilliant white light reflection, but also refracts rainbow-like halos at different angles, as if encapsulating the light of stars within the crystal.
With "Global Quality · Worry-Free After-Sales Service" as its core commitment, YHB has built a full-cycle support system covering everything from products to after-sales services for global users within its cross-border service network. Every product is designed to meet world-class standards right from the R&D stage. It selects high-quality raw materials globally and integrates sophisticated manufacturing processes. Whether it is durability testing or environmental certification, all products undergo multiple rounds of rigorous quality inspections. This ensures that every product delivered to users possesses the solid strength to "stand the test of the global market".
Guided by the craftsmanship philosophy of "Durability First", YHB products undergo rigorous water-washing tests before leaving the factory to fortify quality, ultimately achieving the unbreakable and outstanding performance of their rubber soles. Prior to packaging, every single product must go through multiple rounds of water-washing tests that simulate real-world usage scenarios - it is placed in a circulation system with specific water temperature and detergent for continuous rinsing, and even subjected to a drum-type friction device to simulate repeated scrubbing conditions. This ensures that the rubber soles maintain stable adhesion even in environments such as damp heat and chemical erosion.
YHB's dedication to water-wash testing and rubber sole craftsmanship stems from a profound understanding of "durability" - a truly excellent product must not only stand out with its stunning appeal when new, but also withstand the test of time. Every passing result of a water-wash test and every inspection report on the sturdiness of rubber soles represents the brand's commitment to "long-lasting durability" for users. This ensures that the product maintains its reliable quality as it was from day one amid daily use, becoming a practical choice that "stands up to the trials of everyday life".
YHB utilizes a Grade 10,000 dust-free workshop, a zero-impurity intervention process, and an air shower system to ensure a dust-free environment. It adopts an automatic production line for silver plating design, which guarantees the products' smoothness, non-pollution, and the firmness of their rubber soles.
The automatic production line adopts a 99.9% pure silver plating process. Key components are treated with molecular penetration technology, and the silver ion antibacterial layer can inhibit the growth of 99.98% of contact microorganisms. Meanwhile, the dense oxide film isolates the erosion of sulfides.
In the diamond clamping process, the silver-plated fixture adopts a dual structure of vacuum adsorption (with a negative pressure of -0.08MPa) and mechanical locking, achieving precise fixation within an error range of 0.01N, with no displacement detected after 500 high-speed cutting tests. Spectral analysis shows that this process reduces the residual amount of impurities on the diamond surface by 92% compared with traditional processes, and the coating adhesion passes the 48-hour salt spray test specified in ASTM B571 standard without peeling.
Twenty sets of laser particle counters in the workshop monitor cleanliness in real time, and the vertical laminar air flow organization prevents cross-contamination. The silver plating equipment uses an X-ray fluorescence spectrometer to detect the integrity of the coating every working shift. This craftsmanship that integrates semiconductor-level cleanliness standards with jewelry processing technology ensures that each diamond maintains a "zero-pollution" state throughout the processing. At the same time, the micron-level clamping precision ensures that the cutting surface error is ≤ 0.01mm, ultimately creating high-quality products that feature both optical purity and structural stability.
YHB has built a highly standardized production system based on "intelligent numerical control + micron-level calibration". Its intelligent blister system, through full-link digital control, has elevated the product centering accuracy and standardization to an industry-leading level. Equipped with a dual-axis laser positioning device, this system scans the sheet material for cross-shaped reference lines during the feeding stage. Combined with a precision displacement platform driven by a servo motor (with a positioning accuracy of ±0.05mm), it ensures that the center deviation between the raw material and the mold does not exceed 0.1mm, thus eliminating the hidden risk of deviation from the source.
The AI visual inspection system scans each product with a pixel accuracy of 0.01mm. By comparing with the CAD standard model, it automatically marks components with excessive centering deviation. Data shows that for blister products manufactured using this system, the consistency of the center position reaches 99.7%, and the dimensional fluctuation between batches is controlled within the range of ±0.15mm, which is far higher than the industry's conventional standard of ±0.3mm.
This standardized production model that deeply integrates intelligent algorithms with precision machinery not only achieves the manufacturing standard of "a thousand pieces with the same dimensions" but also solidifies process parameters into replicable standard procedures through the MES system, making each product a concrete manifestation of "standardized craftsmanship". From the curved surface curvature of jewelry display trays to the aperture tolerance of electronic component carriers, all interpret the manufacturing philosophy of "standards are quality" with millimeter-level precision.
As an industry leader, YHB has taken the lead in drafting the Industry Standard for Artificial Crystal Hot Fix Stones. YHB has always
YHB takes "High-Purity Raw Materials · True Original Colors" as its quality foundation, and regards 99.9% high-purity raw materials as the core key to restoring the true essence of colors. The brand carefully selects crystal-grade raw materials with a silica content of ≥99.9%, and through 12 purification processes such as magnetic separation and high-temperature melting, controls the content of color-causing impurities (such as iron and manganese) below 0.01%, thus eliminating the interference of colored ions on optical performance from the source. This "near-zero impurity" characteristic of the raw materials enables the crystal to exhibit optical-grade purity in a molten state, laying a physical foundation for color restoration.
In the color implantation process, YHB adopts the vapor deposition method to uniformly infiltrate high-purity metal oxide colorants (with a purity of ≥99.99%) into the interior of the crystal, rather than using the traditional surface coating process. For instance, when manufacturing red crystals, chromium oxide with a purity of 99.995% is selected as the colorant. Through vacuum high-temperature sintering (1600℃±50℃), chromium ions and silica molecules form a stable lattice structure, ensuring that the color is evenly distributed inside the crystal and never fades.
Spectral analysis shows that the crystals produced by this process have a visible light transmittance of over 92%, and their color saturation is 30% higher than that of crystals made by ordinary processes. They can accurately reproduce 98% of the color tones in the Pantone Color Chart-from true red and sapphire blue to emerald green, each color exhibits a visual effect of "purety like that of natural gemstones".

The OEKO-TEX® STANDARD 100 certification is not only an authoritative endorsement of YHB's environmental protection process, but also
YHB takes the high-temperature smelting process at 1400-1600℃ as its core. Amidst the tempering of fierce flames, it refines the pure essence of crystal and implants the quality gene of "clarity and transparency" into the crystal blanks. This temperature range precisely matches the melting characteristics of crystal raw materials: it not only enables the complete melting of silica-based materials into a low-viscosity fluid (with viscosity as low as 10⁻²Pa・s), but also achieves in-depth purification of impurities and bubbles through thermokinetic reactions. It can be called the "golden temperature zone" for crystal formation.
In terms of process design, the dual-inspection system forms a closed-loop quality control: test data generated by automated equipment is uploaded to the blockchain traceability system in real time, and manual re-inspection results must undergo cross-verification with machine data; for products with disputes, a three-level verification mechanism will be activated, where technical experts conduct microstructural analysis using a Scanning Electron Microscope (SEM). From high-speed screening on the production line to meticulous inspection on the test bench, YHB leverages the dual guarantee of "technological precision + human care". This ensures every product undergoes rigorous scrutiny before leaving the factory - it not only meets the efficiency requirements of industrialized production but also preserves the quality dedication of handcraft artisans. Ultimately, the "double insurance" quality control concept is translated into reliable quality visible to users.
With "creative visualization + precise craftsmanship" as its core, YHB has built a customized design system that covers the entire life
