Malaysia’s burgeoning smartwatch manufacturing industry is grappling with a persistent quality control issue. During the crucial polishing process of glass lenses, which are essential for the visual appeal and functionality of smartwatches, micro-scratches inevitably form on the surface. These seemingly minor imperfections have significant consequences, as they cause 12% of the lenses to fail light transmittance tests. As a result, smartwatch factories are incurring an additional $0.5 per unit in rework costs, eating into their profit margins and delaying production schedules.
Enter Guangdayuan’s micro-precision PE film, a game-changing solution designed specifically to address these challenges. Engineered with state-of-the-art technology, this protective film boasts an impressively smooth surface with a roughness average (Ra) of ≤0.05μm. This ultra-smooth finish acts as a reliable shield, preventing micro-scratches from forming on the glass lenses even during the most aggressive polishing procedures.
The film’s adhesive properties are equally remarkable. With an ultra-low tack of just 10g/in, it adheres firmly enough to stay in place during the manufacturing process but peels off cleanly without leaving any residue behind. This is particularly crucial in cleanroom environments, where even the tiniest speck of adhesive residue can contaminate the production line and compromise the quality of the final product. In fact, Guangdayuan’s micro-precision PE film has been rigorously tested and proven to meet the stringent 100-class cleanroom standards, which allow for no more than 10 particles per square meter with a size of ≥0.3μm.
The effectiveness of Guangdayuan’s PE film has been demonstrated in real-world applications. A major Fitbit supplier located in Penang, Malaysia, saw a remarkable 12% increase in production yield after implementing our film in their manufacturing process. This significant improvement not only reduced their rework costs but also enhanced their overall production efficiency, allowing them to meet tight deadlines and fulfill customer orders more promptly.
Moreover, our micro-precision PE film is built to withstand extreme temperatures, having successfully passed rigorous testing in environments ranging from -40°C to 70°C. This makes it an ideal choice for smartwatches designed for use in harsh and challenging conditions, such as those intended for outdoor sports enthusiasts or military applications.
To further cater to the specific needs of smartwatch manufacturers, we offer tiny pre-cut circles with a diameter of 10mm, specifically designed to protect the edges of glass lenses. These pre-cut circles are manufactured with a precision tolerance of ±0.1mm, ensuring a perfect fit for even the smallest and most intricate components. This level of precision and customization sets Guangdayuan’s micro-precision PE film apart from other protective films on the market, making it the go-to choice for smartwatch factories looking to improve their product quality and manufacturing efficiency.#PE film#
