Our customization service starts with in-depth internal team alignment, tracking your exclusive gel polish production via live factory dashboards (±0.3mm printing accuracy). From formula R&D and color sampling to filling and packaging, our team follows through to ensure the 200 bottles/minute high-speed line perfectly meets your custom needs. We support small-batch customization (starting from 1,000 bottles), achieving formula-process-design alignment within 72 hours to let your brand launch new products quickly. Whether single-color or full-line development, we offer one-stop customization from concept to finished product.

We conduct 5000-cycle scratch tests (500g load, 2.5H hardness), ensuring ≥98% gloss retention (ΔE≤0.4, imperceptible color shift) for your custom gel polish, delivering military-grade resistance to infant nail scratches. This test fully simulates high-frequency wear scenarios such as handwashing, housework, and typing. It not only resists various daily frictions but also ensures the gel polish stays intact on nails for up to 3 weeks without peeling or lifting, maintaining a vibrant color and smooth finish. We also evaluate post-test aging to comprehensively guarantee the durability of your custom gel polish, building a long-lasting reputation for your brand.

The next round of competition in the nail industry is essentially a dual contest of supply chain agility and technological depth. BOZLIN is working with global partners to break through challenges, with "flexible customization capabilities + global compliance certifications" at its core, creating an efficient pathway for brands to access global markets.

From R&D formula discussions to production line inspections, our team collaborates professionally and efficiently to ensure every step of your custom request is precise and controlled. We have 8 IBD/CND certified trainers conducting 120 hands-on trainings annually, providing technical support for your custom products. Production team members are rigorously trained and certified, familiar with every detail of gel polish production, and able to respond quickly to your custom needs. Our team is not just executors—we're your custom consultants, offering professional advice and support anytime.

Our automated filling machine achieves ±0.01g precision (half a sesame seed's weight) for gel polish, paired with a vision-guided capping system for 0.3s/bottle high-speed capping. 99.95% nitrogen purging prevents oxidation, and laser coding assigns a unique ID to each bottle for pharmaceutical-grade traceability. We support 5ml to 30ml multi-spec customization, from brand samples to large bulk orders. The line offers flexible production, switching between bottle types and capacities quickly, and can fulfill small-batch custom orders (starting from 1,000 bottles) in 7 days, providing an efficient and flexible packaging solution for your brand.

Our gel polish holds 7 global certifications (EU REACH, US FDA, Germany LFGB, etc.), with QR-code traceability to verify original test reports (SGS, BV accredited). This builds a full-loop safety system from raw material procurement to finished product delivery. Whether for domestic filing or international export, we ensure compliance for your custom products, enabling smooth market access worldwide. We also track regulatory updates globally, providing ongoing compliance support to let your brand sell confidently across borders.

We subject gel polish to 4hr 85℃ baking + 12hr -40℃ freezing cycles, ensuring peel strength ≥18N/25mm (3× national standards). It maintains stable performance without fading, brittling or peeling even in extreme scenarios such as arctic logistics, tropical outdoors and long-term storage. This test comprehensively verifies product weather resistance and structural stability, providing cross-scenario reliable protection for your custom gel polish. Whether for cross-border e-commerce long-distance transportation or daily storage in offline salons, it can always maintain excellent quality for your customers' peace of mind.

We use a fully sealed vacuum mixing system to blend imported photo-curable resins with nano-pigments at -0.08MPa, isolating air to prevent pigment oxidation. The material then undergoes tri-stage precision grinding in a zirconia bead mill, controlling particle size below 5μm (1/15 of a hair’s diameter) for uniform dispersion. This process boosts color vibrancy by 30% for your custom gel polish and creates a dense coating with industry-leading adhesion, resisting peeling even under frequent nail filing. Whether you need high-opacity solid colors or sheer translucent shades, our precise grinding delivers your desired custom effect.

We degas gel polish materials for 20 minutes at -0.1MPa, using a spiral conveyor to spread the material into a thin film, eliminating 99.7% of micro-bubbles. Laser bubble detectors monitor fluid density in real time, ensuring deviation ≤0.05g/cm³, which prevents pinholes, shrinkage, or uneven surfaces after application. This process delivers a baby-smooth base for your premium custom gel polish, perfect for gradients, marbling, or mirror finishes. We also conduct batch sampling to ensure consistent quality for your custom products.

Welcome to BOZLIN Smart Factory, the core manufacturing base for high-end gel polish worldwide. What you may not know is that 1 out of every 10 bottles of high-end gel polish globally is produced here. With "world-class intelligent manufacturing + stringent safety standards" as our core, we provide professional nail product customization services to clients in 86 countries and regions, empowering brands to build core competitiveness in the global nail care market.

We have established a full-process quality inspection loop from raw materials to finished products, where every bottle of custom gel polish undergoes 30+ rigorous tests: raw materials are tested for purity and harmful substances via spectrometers, particle dispersion (≤5μm) is monitored under microscopes after mixing, bubble residual rate (＜0.01%) is controlled by laser detectors during degassing, ±0.01g precision verification is conducted after filling, and finished products undergo adhesion tests (ensuring 3-week durability), weather resistance tests, and compliance certifications such as EU EN71-3 and US FDA. Our QC team records batch testing data in real time via 0.1mm precision microscopes and data systems, supporting QR-code traceability. This ensures stable quality for large-scale production and precise quality control for small-batch customization, making every bottle of your custom gel polish safe, long-lasting, and compliant.

Our R&D team validated 0.5s/㎡ curing speed (3× faster than traditional methods) via new UV-LED tests, enhancing instant adhesion and scratch resistance. With 12 daily formula iterations, we optimize resin-pigment molecular structures to develop second-level response solutions for FMCG high-speed lines. This innovation boosts your production efficiency and enables faster service turnaround in nail salons, improving customer experience. We continue investing in R&D to provide industry-leading technical support for your brand.
