About

Founded in 2014, Guangdong Qiangdan Technology Co., Ltd. derives its name from the last characters of the founder and his wife’s given names. As a brand focused on mid-to-high-end mobile phone tempered glass, the company integrates R&D, design, production, promotion, and sales. After 12 years of development, it has built a solid operational layout, boasting two modern production plants covering over 30,000 square meters, a 5,000-square-meter brand operation headquarters, a total of 500 employees, and a total investment exceeding 200 million RMB—laying a solid foundation for the brand’s global business expansion. Leveraging the 600,000-unit daily production capacity of its two self-operated plants and a strong R&D and operation team of over 100 people, the brand ensures stable product quality and efficient delivery to meet the needs of the global market.

Research and development

As a R&D-focused manufacturer deeply engaged in the mobile phone tempered glass film sector, we have always adhered to the R&D philosophy of "breaking bottlenecks through technology and defining R&D based on needs". This ensures that every technological breakthrough precisely addresses user pain points, and every product stands the test of both the market and time.

In terms of R&D direction, we reject "follow-the-trend innovation" and insist on identifying needs from users' real usage scenarios. To tackle the pain points of "bubbles easily forming during film application and edges easily lifting", we set up a dedicated R&D team. After 180 days of repeated testing, we developed the "nano-level adhesive coating + flexible edge buffer technology", which increases film adhesion by 30% and enhances edge durability by 50%. To solve the industry-wide challenge of "difficulty in applying films to curved screens and compromised protection effectiveness", we collaborated with university material laboratories to develop high-toughness ultra-thin glass substrates, paired with an adaptive curved surface fitting process—breaking the contradiction between curved screen protection and user experience. We are well aware that R&D goes beyond technological breakthroughs; it also lies in meticulous quality control. Before the implementation of any new technology, it must undergo three rigorous verification procedures: "100,000 wear-resistance tests, 500 drop simulations, and exposure to extreme temperatures ranging from -20℃ to 60℃". This guarantees that the product delivers stable protective performance in various scenarios.

We have always believed that excellent R&D should not be about "piling up technologies", but rather "precise empowerment". With user needs as the anchor, we use continuous technological iterations to break industry bottlenecks, turning every tempered glass film into a "perfect integration of technology and needs" and providing users with more reliable and comfortable screen protection solutions.

Design As a manufacturer specializing in R&D and production of mobile phone tempered glass films, we adhere to the core design philosophy of "ultimate protection, seamless experience", making every film an "invisible guardian" for mobile phones. In protective design, we reject "compromised protection": We select high-alumina-silica glass, enhance surface hardness to 9H via multiple strengthening processes to resist daily scratches and key bumps. We also optimize the anti-explosion structure—even if broken accidentally, micro-particle adsorption technology prevents glass residue splashing, maximizing screen and user safety. We know "protection isn’t the end; experience is key", so we refine details: Precise laser cutting ensures "seamless fit" with different phone screens; edges undergo 2000 rounds of curved polishing to avoid uncomfortable bumps. Equipped with high-transparency optical coating (99.8% light transmittance), it restores screen’s original colors and reduces fingerprints, letting users enjoy strong protection without affecting operation or visual experience. We believe a good tempered glass film shouldn’t be a "burden" but an "extension" of the phone—it safeguards the screen with solid technology and integrates into daily use via delicate design, allowing users to enjoy mobile convenience and fun with peace of mind and comfort.

Sales

As a manufacturer specializing in the production and sales of mobile phone tempered glass films, we have always adhered to the sales philosophy of "customer-centricity, win-win and symbiosis". We regard every cooperation as the starting point of a long-term partnership, and create sustainable value for customers with professionalism and sincerity.

In customer service, we reject "one-time transactions" and insist on providing customized solutions based on customer needs:

• · For offline retail customers, we offer flexible minimum order quantity policies and visualized inventory management support, along with exclusive display materials to help terminal stores improve sales turnover rates.

• · For brand cooperation customers, we set up dedicated docking teams to follow up the entire process from product specification customization, packaging design to logistics and distribution, ensuring accurate and controllable delivery cycles.

• · Even for customers with small-batch purchases, they can enjoy unified after-sales support: if there are product quality issues, we will respond and handle them within 24 hours, ensuring customers have no worries.

We have always believed that excellent sales should not be "one-way promotion", but "value co-creation": Guided by customers' business goals, we use cost-effective products, flexible cooperation models and thoughtful services to reduce customers' cooperation costs and increase cooperation benefits. Ultimately, we achieve long-term win-win results between the manufacturer and customers, and jointly deepen the development of the mobile phone accessories market.
