Insert‑molded Tablet Plastic Mid‑frame

The Insert‑molded Tablet Plastic Mid‑frame is a core precision-molded structural component for tablets, learning devices, and educational tablets. Serving as the central load-bearing chassis, it connects the screen panel to the rear cover while positioning, mounting, and protecting the motherboard, battery, camera, and antenna modules. It is widely used in consumer tablets, student learning tablets, and commercial-grade tablets.

These Insert‑molded Tablet Plastic Mid‑frames are primarily manufactured using PC-ABS alloys or glass-fiber-reinforced PC materials via large-format, thin-wall precision injection molding. The process supports insert molding—embedding copper nuts and metal reinforcement plates directly into the part—and integrates complex features such as screen slots, battery retention ribs, camera cutouts, button mounting slots, screw bosses, antenna clearance zones, and assembly snap-fits in a single molding step, thereby reducing the need for downstream processing.

The plastic material offers excellent insulation properties, minimizing interference with antenna signals. Compared to metal middle frames, these are lighter and provide superior drop-cushioning performance, dissipating impact forces to protect internal electronic components. Surface treatments such as painting, UV coating, or spray-free finishes can be applied to achieve various colors and textures, ranging from matte to high-gloss.

For these large-format frames, flatness and assembly tolerances are strictly controlled to ensure a precise fit between the screen and rear cover, making them suitable for automated assembly lines. Customization based on client drawings allows for adjustments to bezel width, wall thickness, cutout locations, and snap-fit ​​structures, balancing structural integrity, signal performance, and cost-efficiency. They are vital 3C structural components for tablet devices.
