The ultimate image quality and long-term stable operation of the 4K 3D Projector are inseparable from the ingenuity of precision stamping technology. With the core concept of "stamping creates high-quality products, precision ensures performance", it meets the strict requirements of 4K 3D projection for component precision, structural stability and heat dissipation efficiency. From the stamping of core metal components, shell stamping, interface stamping to detailed stamping and polishing, every stamping process follows strict standards. With high-precision stamping technology, it achieves the precision and consistency of component molding, balancing image quality presentation, equipment durability and ease of use. It completely solves the pain points of ordinary projectors such as insufficient stamping precision, loose components and poor heat dissipation, and becomes a quality model in the high-end 4K 3D projection field, interpreting the core strength of high-end projection with exquisite stamping technology.

　　Precision stamping of core metal components lays a solid foundation for image quality and performance. The core metal components of the 4K 3D Projector (heat sinks, lens fixtures, circuit board brackets, etc.) adopt high-precision CNC stamping technology, using high-strength cold-rolled steel plates as stamping base materials. After precise mold positioning and one-time stamping forming, the stamping precision is controlled within ±0.005mm, ensuring that the component size is accurate, the structure is regular, and there is no deformation or burrs. During the stamping process, scratch-free stamping technology is adopted to avoid scratches and depressions on the metal surface, ensuring the flatness and sealing of the components. After stamping, the lens fixture can firmly fix the lens position, avoiding image distortion and double images caused by lens deviation during 4K 3D projection, and ensuring the stable presentation of 4K ultra-clear image quality.

　　The shell stamping is constantly improved to balance texture and protective performance. The body shell adopts an integrated stamping forming process, using lightweight aviation-grade aluminum alloy as the stamping base material. After multiple continuous stamping, bending and shaping processes, the stamping error is ≤0.01mm. The surface of the shell is smooth and flat after stamping, and then undergoes anodizing treatment to form a dense protective layer, which has excellent scratch resistance, wear resistance, corrosion resistance and anti-aging performance, and does not fade or deform after long-term use. During the stamping process, the curvature and thickness of the shell are accurately controlled, which not only ensures the lightweight of the body (weight controlled within 4.5kg), but also improves the structural strength of the body, which can withstand slight collisions and extrusions. At the same time, the stamping-formed shell has excellent sealing performance, which can effectively isolate dust and water vapor from entering the body and protect the core components from damage.

　　The interface and heat dissipation components are precisely stamped to meet high-end usage needs. The metal contact points of the interface adopt precision stamping technology, using high-conductivity phosphor bronze as the stamping base material. After stamping, they are gold-plated, with uniform contact thickness and accurate contact area, smooth plugging and unplugging, and stable conductive performance. It is suitable for 4K high-definition signal transmission, avoiding signal freezes and interruptions caused by insufficient stamping precision of the contact points, and perfectly compatible with various high-end equipment such as computers, set-top boxes and U disks. The heat dissipation components are formed by multi-tooth precision stamping. During the stamping process, the tooth pitch and tooth height are accurately controlled to maximize the heat dissipation area. At the same time, the stamping-formed heat dissipation channel is regular and smooth, which can quickly export the heat generated during the operation of 4K 3D projection, avoiding image quality degradation and frequent failures caused by overheating of the equipment, and ensuring the stable operation of the equipment 24 hours a day, 7 days a week.

　　The detailed stamping and polishing are strict, showing high-end quality. Each stamping component is subjected to precision polishing and deburring treatment, and the corners are formed by stamping rounded corners to avoid potential safety hazards and inconvenience caused by sharp corners; the detailed parts such as the body logo and interface grooves are formed by precise stamping positioning, with accurate size and close connection, improving the overall delicacy of the equipment. Each stamping process is equipped with professional testing equipment to strictly test the stamping precision, component flatness and structural integrity. Unqualified products are reworked, ensuring that the stamping components of each 4K 3D Projector meet high-end standards. With extreme stamping technology, it empowers the 4K ultra-clear 3D projection experience, adapting to diverse high-end scenarios such as home theaters, high-end offices and audio-visual entertainment.
