Focusing on key components of Little Genius smartwatches, we adopt a composite PVD process combining magnetron sputtering and multi-arc ion plating to precisely match the brand's color needs. It can achieve diverse color effects such as solid colors and gradients, with a color error ≤±2% and strong consistency in mass production, adapting to the differentiated designs of various product series.
Long-lasting Vivid Colors: PVD coatings show no fading after 2000 hours of UV aging tests, maintaining a fresh appearance during long-term wear.
Eco-friendly and Safe: Vacuum-based dry plating produces no heavy metal-containing wastewater, passing ROHS and REACH certifications, and meeting safety standards for children's skin contact.
Wear-resistant and Kid-friendly: With a coating hardness of 2200HV, it withstands over 100,000 cycles of wear tests without scratches; salt spray tests exceeding 500 hours ensure corrosion resistance. The coating adhesion reaches 4B level, remaining intact even after 1.5-meter drop tests.
Collaborating with Little Genius' R&D team, we optimize PVD pre-treatment processes for component materials without affecting assembly precision or functional use. Supported by 16 high-precision PVD equipment, our annual production capacity exceeds 1 million units. Through full-process quality control, we ensure stable supply. The solutions have been applied to mainstream models in the Q Series and Z Series, gaining recognition from both the brand and consumers.
Components undergo automatic eco-friendly cleaning pre-treatment; PVD plating parameters are monitored in real-time during the process. Before delivery, products pass multiple tests including wear resistance, salt spray, and harmful substance detection, with complete test reports provided to meet strict standards for children's products.
