The high-quality adaptability and long-term stability of the classroom 3D projector stem from strict molding technology and scientific molding control. With the core concept of "molding determines quality, adaptability promotes teaching", it caters to the core needs of classroom teaching scenarios such as high-frequency use, multi-environment adaptation and easy operation. From shell molding, optical component molding, core component molding to whole machine assembly molding, every molding process is refined to the utmost, balancing durability, convenience and teaching adaptability. It completely solves the pain points of ordinary 3D projectors such as rough molding, poor adaptability and easy damage, and becomes a high-quality equipment to empower classroom teaching and improve teaching efficiency, creating a quality benchmark for classroom use with exquisite molding technology.

　　The shell is precisely and regularly molded, adapting to the complex use scenarios of the classroom. Adopting integral injection molding technology, high-strength environmentally friendly ABS engineering plastic is used as the molding base material. After precision mold pressing and high-temperature curing molding, the molding error is controlled within ±0.1mm. The shell surface is smooth and flat, without burrs or defects, and the corners are rounded to avoid potential safety hazards to teachers and students caused by sharp corners. Anti-scratch and anti-aging additives are added during the molding process, making the shell have excellent scratch resistance, wear resistance and anti-aging performance, which can withstand high-frequency movement, wiping and slight collision in the classroom. It does not fade, deform or crack after long-term use, and also has certain dust-proof and drop-proof performance, adapting to the high-dust and high-frequency use scenarios of the classroom.

　　The optical components are strictly molded to ensure clear and stable 3D projection image quality. The core optical components adopt high-precision mold pressing molding technology. The lens is made of high-transparency optical glass, which is processed by multiple precision grinding and polishing processes, with a molding precision of 0.001mm, ensuring that the light transmittance is as high as 98% or more. The projected 3D image is clear and delicate, free of distortion and double images, with high color restoration, adapting to different lighting environments in the classroom. Even under natural light, it can present clear 3D images, helping teachers and students capture teaching details clearly. The packaging and molding of optical lenses adopt sealed integrated molding, which effectively isolates dust and water vapor from entering, avoids image quality degradation caused by dampness and dust accumulation of optical components, and extends the service life of optical components.

　　The core components are precisely molded to lay a solid foundation for equipment operation. The core projection chip adopts precision packaging molding technology, with a chip packaging error ≤0.005mm, ensuring that the chip is closely connected to the circuit board and the signal transmission is stable, avoiding problems such as overheating and frequent failures caused by improper packaging and molding, and ensuring the 3D projector runs stably 24 hours a day, 7 days a week, adapting to the continuous teaching needs of the classroom. The heat dissipation module adopts an integrated molding design, which is created by precision die-casting molding technology. The heat dissipation channel is regularly and smoothly molded, and the heat dissipation area is accurately controlled, which can quickly export the heat generated by the equipment operation, avoid equipment freezes and shutdowns caused by overheating, and ensure the continuous and smooth 3D projection teaching.

　　The whole machine is assembled and molded in a standardized manner, balancing adaptability and convenience. The whole machine adopts modular precision assembly molding technology. Each component is installed through precise positioning and standardized fixing. The molded equipment has a compact and stable structure, and the weight of the machine is controlled within 5kg, which is convenient for moving, installing and debugging in the classroom, adapting to the deployment needs of classrooms of different sizes. The interface part adopts embedded molding technology, the interface is closely connected with the machine body, plugging and unplugging is smooth and not easy to loose, adapting to the connection needs of various teaching equipment in the classroom (computers, U disks, whiteboards, etc.). At the same time, every connection gap is strictly controlled during the molding process to improve the overall sealing and dust-proof performance of the equipment. After each projector is molded, it undergoes strict molding testing to ensure that the appearance, performance and adaptability meet the special standards for classrooms, empowering efficient 3D classroom teaching with extreme molding technology.
