Promotional shaped tin box, as an exclusive customized metal container for promotional scenarios, its R&D core focuses on four core goals: promotional drainage, brand communication, practical adaptation, and batch landing. It breaks the industry pain points of traditional promotional boxes such as "single shape, weak functionality, low brand recognition, and poor adaptability". After five core stages of market research, scheme design, process R&D, sample testing, and batch optimization, it has been elaborately developed for several months. Finally, it has created a shaped promotional tin box that combines promotional attributes, brand texture, and practical value, becoming the core carrier for enterprise promotion, activity drainage, and brand promotion. It not only meets the drainage needs of promotional scenarios but also conveys brand concepts, realizing the original R&D intention of "win-win between promotion and brand".

　　This R&D work is guided by market demand, centered on brand communication, based on practicality and durability, and targeted at batch landing. A professional R&D team has been set up, covering talents in various fields such as market research, industrial design, material R&D, and process engineers. The closed-loop R&D process of "research-design-R&D-test-optimization" is followed throughout. Each R&D link has been repeatedly polished and strictly controlled to ensure that the product not only meets the core needs of promotional scenarios but also has the advantages of mass production, high cost performance, and strong adaptability. At the same time, it takes into account the texture of metal materials and the creativity of shaped design, making the promotional box no longer a simple "gift container", but also a mobile carrier for brand communication, improving the grade and effect of promotional activities.

　　1. Early R&D Stage: Market Research and Demand Analysis, Laying the Foundation for R&D. The core premise of R&D is to accurately match market demand. In the early stage of this R&D, the team carried out a 30-day comprehensive market research, covering multiple mainstream promotional scenarios such as food, beauty, digital, catering, and cultural and creative industries. It visited more than 200 enterprise customers and more than 50 offline promotional activity sites, collected more than 1,000 valid research samples, comprehensively analyzed the core pain points and needs of promotional scenarios, and clarified the direction and focus for the R&D work.

　　The research results show that the current promotional box market has four core pain points: first, the shape is single, mostly conventional square and round, lacking creativity, which is difficult to attract consumers' attention and cannot meet the core demand of promotional drainage; second, the functionality is weak, it can only be used as a gift container, has no additional practical value, and is easy to be idle after the promotion, which cannot realize long-term brand exposure; third, the brand adaptability is poor, the customization space is limited, it is difficult to accurately convey brand concepts and core information, and the brand recognition is low; fourth, mass production is difficult, shaped design is prone to process defects, and the cost is high, which cannot meet the needs of enterprises for bulk purchase. In response to the above pain points, the R&D team clarified three core R&D directions: first, the R&D of creative shaped designs, balancing visual appeal and mass production feasibility; second, the R&D of function integration, adding practical functions, extending the service life of products, and realizing long-term brand exposure; third, the R&D of customized adaptation, optimizing customization processes, reducing bulk customization costs, and improving brand communication efficiency.

　　At the same time, the R&D team decomposed differentiated R&D priorities according to the promotional needs of different industries: the food industry focuses on moisture-proof, sealing, and food safety, and needs to adapt to the storage needs of snacks, candies and other products; the beauty industry focuses on exquisite texture and portability, and needs to fit the storage and display of beauty samples and trial packs; the digital industry focuses on drop-proof and wear-resistant, and needs to protect small digital accessories; the cultural and creative industry focuses on creative design and personalization, and needs to adapt to the tone of cultural and creative products. In addition, the team also investigated the core parameters such as materials, processes, and costs in the current metal box industry, compared the cost performance of different materials and the feasibility of different processes, providing data support for subsequent material selection and process R&D, ensuring that the R&D products not only meet market demand but also have industry competitiveness.

　　2. Mid-term R&D Stage: Scheme Design and Core Breakthroughs, Creating Product Differentiation. The mid-term R&D focuses on R&D work in four dimensions: shape, material, process, and function. Combined with the early research needs, the design scheme is repeatedly optimized, multiple technical difficulties are broken through, and product differentiation advantages are created to ensure that the product has both creativity, practicality, and mass production.

　　In terms of shaped design R&D, the R&D team abandoned the traditional conventional shapes, and designed a variety of creative shaped schemes combined with the drainage needs of promotional scenarios and the brand tone of different industries, including three categories: brand LOGO shape, product shape, and festival-specific shape, such as snack shape for the food industry, lipstick shape for the beauty industry, earphone shape for the digital industry, and heart and star shapes for festival scenarios. To balance visual appeal and mass production feasibility, the team adopted the R&D idea of "creative simplification + structural optimization". While retaining the shaped creativity, it optimized the shape lines, avoided overly complex edges and arcs, and reduced process difficulty. For example, for the brand LOGO shape, the R&D team used 3D modeling technology to simplify and optimize the LOGO outline, ensuring that the shape is smooth and has no sharp edges, which not only restores the brand logo but also facilitates mass stamping forming; for the festival shape, the shape ratio is optimized to ensure that the shape is full and the structure is stable, and the overall size is controlled to adapt to the portability needs of promotional gifts. In addition, the team repeatedly adjusted the shape details through multiple 3D printed samples to ensure that the shaped shape is not only beautiful but also can meet the internal storage needs, avoiding the problem of "being good-looking but not useful".

　　In terms of material R&D, the R&D team took "safety, durability, high cost performance, and adaptation to promotional scenarios" as the core, compared various metal materials such as food-grade 304 stainless steel, high-quality iron, and tinplate, and combined with the promotional needs of different industries, finally determined two core material schemes, which can flexibly adapt to different scenarios and budgets. Among them, the food industry prefers food-grade 304 stainless steel, which meets the GB 4806.9-2016 standard for metal materials in contact with food, is free of harmful substances and odors, has good moisture-proof, anti-oxidation, and corrosion-resistant performance, can be directly in contact with food, and is suitable for the storage of snacks, candies and other products; other industries use high-quality iron, which has undergone multiple anti-rust and anti-corrosion processes, with tough texture and not easy to deform, outstanding cost performance, and suitable for bulk purchase needs. At the same time, the R&D team optimized the material thickness, controlling it between 0.35-0.5mm, which not only ensures the sturdiness of the product but also controls the product weight, facilitating carrying and bulk transportation, balancing practicality and economy.

　　In terms of process R&D, in response to the difficulties in mass production of shaped shapes, the R&D team broke through multiple process bottlenecks, optimized the production process, and ensured stable product quality and efficient mass production. The key points of core process R&D include three aspects: first, the integrated stamping forming process. The R&D team optimized the stamping die, adopted high-precision stamping equipment, and stamped the metal plate into shape at one time, avoiding process defects caused by splicing, and at the same time improving production efficiency and reducing the cost of mass production; second, the surface treatment process. According to different materials and customization needs, the team developed four core processes: environmentally friendly baking paint, silk screen printing, laser engraving, and gold stamping. The environmentally friendly baking paint process has uniform color and is not easy to fade, adapting to various color customizations; the silk screen printing process has clear details and low cost, adapting to mass text and pattern customization; the laser engraving process has high texture and is not easy to wear, adapting to brand LOGO and simple text customization; the gold stamping process has a prominent grade and good visual effect, adapting to high-end promotional scenarios. All surface processes have passed environmental testing, no harmful volatiles, and meet international environmental standards; third, the edge treatment process. In response to the problem that the edges of shaped shapes are prone to burrs and sharp edges, the R&D team adopted multiple rounded corner polishing processes, with a polishing accuracy controlled within 0.01mm, ensuring that the edges are round and smooth, avoiding scratching hands, and improving the safety of use.

　　In terms of function integration R&D, the R&D team added multiple practical functions combined with the practical needs of promotional scenarios, making the promotional box no longer a simple gift container, extending the service life of the product, and realizing long-term brand exposure. The core function R&D includes: first, the sealing and moisture-proof function. Optimize the connection structure between the box cover and the box body, add a food-grade silicone sealing ring to ensure good sealing performance, which can effectively prevent moisture, dust, and leakage, adapting to the storage needs of food, beauty and other products; second, the layered storage function. In response to the storage needs of multi-category gifts, develop a detachable layered partition, which can flexibly adjust the storage space, avoid messy stacking of gifts, and improve practicality; third, the portable function. Develop a simple metal handle or lanyard design on the side of the box body, which is convenient for consumers to carry, and at the same time improves the portability and display of the product; fourth, the customization function. Optimize the customized area on the surface of the box body, reserve a standardized customized space, support mass customization of brand LOGO, promotional information, activity themes and other content, and improve brand recognition and promotional effect.

　　3. Late R&D Stage: Sample Testing and Batch Optimization, Ensuring Product Landing. The late R&D stage focuses on three links: sample testing, problem rectification, and batch optimization, ensuring that the product quality meets the standards, mass production is feasible, and adapts to market demand, laying the foundation for product mass landing.

　　In the sample testing stage, the R&D team made a variety of samples with different shapes, materials, and processes, and carried out multi-dimensional testing, including three categories: quality testing, function testing, and mass production testing. Quality testing includes material testing, process testing, and durability testing. Material testing ensures that the material meets food-grade standards and is free of harmful substances; process testing checks for process defects in stamping, surface treatment, edge polishing and other links to ensure that the product surface is smooth, free of burrs, and no discoloration; durability testing includes drop testing, wear testing, and sealing testing. Drop testing ensures that the product does not deform or damage when dropped from a height of 1.5 meters; wear testing ensures that the surface process is not easy to wear and fade; sealing testing ensures that the product has good sealing performance and no leakage. Function testing simulates actual use scenarios for functions such as sealing, layering, portability, and customization to test the practicality and stability of the functions. For example, sealing testing simulates a humid environment to test the moisture-proof performance of the product; layering testing simulates the storage of multi-category gifts to test the flexibility and stability of the partition.

　　Mass production testing simulates mass production scenarios, tests the batch adaptability of processes such as stamping and surface treatment, identifies possible problems in mass production, optimizes the production process, improves production efficiency, and reduces production costs. In response to the problems found in the test, the R&D team rectified and optimized them one by one: for the problem that some shaped shapes are prone to deformation during stamping, optimize the precision of the stamping die, adjust the stamping force and speed to ensure stable stamping forming; for the problem that the surface baking paint is easy to fade, optimize the baking paint process, add a high-temperature curing link to improve the adhesion of the baking paint, ensuring that it is not easy to fade or fall off; for the problem of insufficient sealing performance, optimize the size and material of the sealing ring, adjust the connection structure between the box cover and the box body to improve the sealing effect; for the problem of low mass production efficiency, optimize the production process, realize the assembly line operation of stamping, surface treatment, edge polishing and other links, and improve mass production efficiency. After multiple rounds of testing and rectification, all indicators of the samples have reached the R&D standards, meeting market demand and mass production requirements.

　　In the batch optimization stage, the R&D team further optimized the product design and production process combined with the needs of mass production, reduced the cost of mass production, and improved the cost performance and market competitiveness of the product. On the one hand, optimize the material procurement channel, establish long-term cooperation with regular manufacturers, purchase raw materials in bulk, and reduce raw material costs; on the other hand, optimize the production process, simplify redundant links, improve production efficiency, and reduce the production time and cost per unit product. At the same time, the R&D team optimized the product specifications according to the bulk purchase needs of different industries, launched a variety of products with different sizes and shapes, adapted to the bulk purchase needs of different promotional scenarios, and provided flexible customization services, supporting mass customization of brand LOGO, promotional information and other content, meeting the personalized promotional needs of enterprises.
