Insert‑molded Plastic Mid‑frame

The Insert‑molded Tablet Plastic Mid‑frame is the core precision injection molded structural component of tablet computers, education and learning tablets, and commercial industry tablets. It serves as the middle load-bearing base of the whole machine and connects the screen panel and the device.

The back cover provides positioning support and physical protection for the motherboard, battery, camera module, and antenna components.

The Mobile Phone Plastic Middle Frame is a core, integrated injection-molded structural component. Typically made from PC-ABS or glass-fiber-reinforced PC, it is manufactured using precision thin-wall injection molding. It integrates features such as screen positioning slots, mounting points for the motherboard and battery, camera cutouts, button mounts, screw bosses, and antenna channels. The frame serves to support and secure the screen, motherboard, and battery while providing shock absorption, drop resistance, and electrical insulation. It is widely used in budget smartphones, feature phones, and 5G devices; some designs utilize insert molding—incorporating embedded metal nuts or reinforcement plates—to enhance structural strength.
