In addition, we have established long-term R&D cooperation relations with many universities and scientific research institutions, introduced cutting-edge R&D concepts and technologies, regularly carried out R&D training and technical exchanges, continuously improved the professional capabilities of the R&D team, and ensured that R&D technology is always at the forefront of the industry.

　　Systematic R&D Process, Ensuring the Implementation of R&D Achievements. We have established a full-process systematic R&D system of "market research — demand analysis — scheme design — sample R&D — test optimization — mass conversion". Each R&D link is strictly controlled and accurately grasped to ensure that R&D achievements can be quickly converted into mass production capacity to meet the market's bulk purchase needs. Step 1: Market Research and Demand Analysis: Set up a professional research team to conduct in-depth research on the core needs of bulk purchase groups such as schools, stationery dealers and enterprise customers, analyze the pain points and deficiencies of existing metal pencil boxes in the market, collect multi-dimensional demand data such as materials, structures, sizes, prices and customization, and form a detailed demand research report to point out the direction for R&D work; Step 2: Scheme Design: Combining with the demand research report, the R&D team carries out multi-dimensional design such as product structure, material selection, process design and customization scheme, forms multiple sets of R&D schemes, and determines the optimal R&D scheme through repeated demonstration, comparison and optimization, ensuring that the scheme not only meets the needs of mass production, but also meets the core demands of customers; Step 3: Sample R&D: Relying on cutting-edge R&D equipment, develop samples according to the optimal scheme, accurately control every detail, create samples that meet the standards, and conduct preliminary tests on the structure, material and process of the samples; Step 4: Test Optimization: Establish a strict sample testing system to conduct comprehensive tests on the durability, sealing, storage, environmental protection and mass adaptability of samples, simulate mass production scenarios and daily use scenarios, collect test data, and conduct repeated optimization and improvement for the problems found in the tests until the samples meet the mass production standards and customer needs; Step 5: Mass Conversion: Convert the optimized R&D achievements into mass production processes, formulate standardized mass production processes, optimize production equipment and production parameters, ensure that R&D achievements can be efficiently and stably converted into bulk products, and realize seamless connection between R&D and production.

　　Outstanding Core R&D Highlights, Empowering the Competitiveness of Bulk Products. Focusing on the core needs of bulk metal pencil boxes, breaking through traditional R&D bottlenecks, creating three core R&D highlights, balancing practicality, economy and adaptability, and improving the market competitiveness of bulk products. First, material R&D innovation: Select cost-effective and durable metal materials, focusing on 0.25-0.3mm thick cold-rolled iron plate and tinplate. After special anti-rust and anti-scratch treatment, the salt spray test can reach 120 hours, which is not easy to oxidize and rust even in humid environment. At the same time, it reduces material costs, adapts to the cost control needs of mass production. The materials meet national environmental protection standards and children's product safety standards, with no harmful residues and no excessive heavy metals, which can be used safely. It also supports multiple material choices such as frosted iron and matte metal, adapting to the needs of different customers; Second, structural R&D optimization: Aiming at mass use scenarios, optimize the pencil box structure design, adopt one-piece stamping structure, and the corners are rounded and polished to avoid scratching clothes or fingers. At the same time, design layered storage compartments, which can flexibly store various stationery such as pencils, gel pens, erasers and rulers, balancing storage practicality and use convenience. Some styles can be designed with magnetic suction opening and closing, buckle closing and other structures to improve the use experience. At the same time, optimize the structural process, reduce the difficulty of mass production and improve production efficiency; Third, process R&D upgrading: Develop efficient processes suitable for mass production, optimize core processes such as stamping, welding, printing and polishing, adopt intelligent CNC stamping technology, control stamping accuracy within ±0.01mm to ensure consistent size of bulk products, adopt environmental protection printing technology, support four-color and spot color printing, with clear printing and not easy to fade, adapting to mass customization needs. At the same time, optimize the process flow, shorten the production time of a single product to less than 1 minute, greatly improve mass production efficiency and reduce production costs.

　　Fruitful R&D Achievements, Adapting to Diverse Bulk Needs. After years of R&D accumulation, we have formed rich R&D achievements, creating a variety of series and specifications of bulk metal pencil box products, covering three series: student version, office version and gift version. Each series has a variety of sizes and styles to choose from, adapting to the needs of different bulk purchase scenarios. Student version: Focus on simplicity and practicality, the size is suitable for students' schoolbags, adopt wear-resistant and scratch-resistant materials, design layered storage, adapt to scenarios such as school bulk purchase and stationery store bulk purchase, and support campus logo and school motto customization; Office version: Focus on simplicity and elegance, adopt matte metal materials, with outstanding texture, design reasonable storage space, adapt to scenarios such as enterprise bulk purchase and office gift bulk customization; Gift version: Focus on delicacy and beauty, adopt high-end processes such as gold stamping and screen printing, support brand logo and pattern customization, adapt to scenarios such as enterprise gift bulk customization and holiday gift bulk stock-up. At the same time, the R&D team continues to promote technological iteration, investing 8% of sales in R&D innovation every year, and has obtained a number of R&D patents, covering multiple fields such as structural design and process optimization. It continuously optimizes product quality and mass adaptability, and can quickly carry out customized R&D according to customers' personalized bulk needs, completing sample making within 7 working days, ensuring that bulk products not only meet customer needs, but also have high quality and high cost performance, empowering bulk purchase with R&D achievements and helping customers achieve differentiated competition.
