SIM Card Tray

As mobile phone bodies become increasingly thinner and lighter, the strength and precision of the SIM card tray have become critical factors affecting the overall reliability of the device. This product is made of SUS304 stainless steel using the MIM (Metal Injection Molding) process and has passed a 4-hour salt spray test. It features an ultra-thin 0.1mm wall thickness design and reinforcing ribs, reducing weight while increasing bending strength by 300% compared to traditional plastic card trays. The precision guide rails and locking mechanism inside the card tray are formed in a single process, ensuring smooth SIM card insertion and accurate positioning, preventing interference with antenna signals.

Product Feature And Application

MIM Process Advantages and Product Characteristics:
Ultra-high strength and lightweight design: The MIM process enables the combination of complex internal reinforcing structures and extremely thin walls, withstanding over 5kg of pressure without deformation at a weight of only 0.5g.
Excellent dimensional stability: The sintering shrinkage rate is controllable within ±0.3%, ensuring high batch consistency and compatibility with automated assembly lines.
Material characteristics: The 304 material can pass a 24-hour salt spray test, and the magnetic polishing surface treatment ensures both aesthetic appeal and corrosion resistance.
