The light weight, portability and long-term durability of the portable 3D projector are mainly empowered by exquisite injection molding technology. With the core concept of "injection molding ensures thinness and lightness, and exquisite craftsmanship ensures stability", it caters to the core needs of portable equipment such as being light and easy to carry, adapting to multiple scenarios, and being damage-resistant and durable. From the injection molding of the body shell, internal structural parts, interfaces to detailed injection molding and polishing, every injection molding process follows strict standards. With high-precision injection molding technology, it achieves the thinness, integration and consistency of component molding, balancing portability, protection and 3D projection performance. It completely solves the pain points of ordinary portable projectors such as rough injection molding, heavy body and easy damage, and becomes the preferred equipment for outdoor entertainment, mobile office and home portable projection, interpreting the core advantages of portable 3D projection with exquisite injection molding technology.

　　The body shell is precision injection-molded, balancing thinness, lightness and structural strength. Adopting an integrated precision injection molding process, lightweight and environmentally friendly PC+ABS alloy is used as the injection base material, which combines the high strength of PC material and the toughness of ABS material. After multiple processes such as precision mold positioning, high-temperature injection molding and cooling setting, the injection precision is controlled within ±0.01mm, ensuring that the body shell is regularly formed, free of burrs and shrinkage marks, and the surface is smooth and delicate. During the injection molding process, the thickness and weight of the body are accurately controlled, the total weight of the whole machine is controlled within 1.2kg, and the thickness of the body is only 28mm, achieving extreme thinness and lightness, which is easy to carry and store. At the same time, the injection-molded shell has a compact structure, excellent impact resistance and drop resistance, which can withstand slight collisions and extrusions outdoors, avoid body damage, and adapt to complex use scenarios such as outdoor and mobile use.

　　The internal structural parts are precisely injection-molded, laying a solid foundation for equipment operation. The core internal structural parts of the portable 3D projector (lens bracket, circuit board fixing seat, heat dissipation module shell, etc.) adopt high-precision injection molding technology, using flame-retardant PC injection base material. After precision injection molding, the structural size is accurate, perfectly matching the body shell and core components, without looseness or deviation. During the injection molding process, insert injection molding technology is adopted to integrally inject metal inserts and plastic base materials, improving the connection strength and stability of structural parts. After injection molding, the lens bracket can firmly fix the lens, avoiding image distortion and double images caused by lens shaking during mobile carrying, ensuring clear and stable 3D projection image quality, and effectively protecting internal core components from damage during transportation and carrying.

　　The interface and detailed injection molding are constantly improved to meet the needs of portable use. The interface part adopts embedded injection molding technology, using high-toughness PVC injection base material, which is integrally injection-molded with the body. The interface is closely connected with the body without gaps, plugging and unplugging is smooth, and it is not easy to loose or fall off. It is compatible with various common interfaces such as USB and HDMI to meet the projection connection needs. At the same time, the injection-molded interface has excellent protection performance, which can effectively isolate dust and water vapor, avoid interface oxidation and poor contact, and ensure stable signal transmission. The detailed parts such as body buttons and heat dissipation holes are formed by precise injection molding positioning, with accurate size and comfortable hand feel. The heat dissipation holes are regularly injection-molded to ensure smooth heat dissipation, avoid overheating of the equipment during operation, and the injection-molded buttons have sensitive rebound and convenient operation, which fits the use habits of portable equipment.

　　The injection molding process is strictly controlled to ensure quality consistency. Each injection molding process is equipped with professional testing equipment to strictly test the injection precision, component flatness, structural integrity and material performance, preventing products with injection defects from entering the next process. During the injection molding process, the injection temperature, pressure and time are strictly controlled to ensure that the injection parts of each portable 3D projector have consistent size and quality. At the same time, environmentally friendly injection raw materials are used, no harmful substances are precipitated, which meets international environmental standards and is safer to use. With exquisite injection molding technology, it achieves a double breakthrough in thinness, portability, durability and stability, allowing the portable 3D projector to be easily carried and stably present clear and smooth 3D image quality, adapting to diverse portable scenarios such as outdoor camping, mobile office and home entertainment.
