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.

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.

We offer professional technical training on gel application and extensions (supported in 7 languages), along with material display and promotion design to boost your store's competitiveness. We collaborate with top domestic nail academies for style design and practical demonstrations, helping your brand build differentiation. As your growth partner, we share industry trends, color forecasts, and marketing tips to make your custom products stand out. Whether you're a small salon or a chain, we provide tailored value-added services for mutual growth.

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.

After a wonderful Chinese New Year holiday rest, we're energized and ready to reconnect. A new year brings a fresh start, and there's no better time to pick up where we left off—or start something completely new. Our team is here, fully committed to understanding your needs and delivering the quality you deserve. Let's walk into 2026 together and make it a year to remember.

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.

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.

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.

Welcome to BOZLIN Smart Factory, the core manufacturing base for high-end gel polish worldwide.

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.

Our R&D team uses Olympus BX63 microscopes to monitor pigment dispersion (5μm precision), adding color paste in 0.01g increments for ΔE＜1 precise coloring (imperceptible to the naked eye). With a database of 500+ mature base formulas, we quickly respond to custom requests—whether low-VOC eco-formulas, fast-curing formulas, or special effects (cat eye, holographic)—completing R&D and sampling in 7 days. The lab also has small-scale constant-temperature dispersion testers and micro vacuum defoamers, ensuring 1:1 parameter matching between lab trials and mass production for smooth formula scaling.

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.

We have established a delivery system integrating "production-logistics-delivery". Domestic orders are shipped within 24 hours, using custom shockproof packaging to secure gel polish bottles, preventing breakage or leakage during transportation and ensuring your custom products (with 3-week long-lasting adhesion technology) arrive intact. For international orders, we connect with customs green channels, providing MSDS, EU REACH/US FDA compliance documents, and completing customs clearance within 3 working days, supporting fast delivery to our global agent network covering 12 countries. Whether for small-batch customization (starting from 1,000 bottles) or large-scale bulk orders, our intelligent warehouse system enables rapid sorting and shipping, with QR-code traceability for real-time logistics tracking, allowing you to expand globally with confidence.
