Customized mobile phone components (such as middle frames, camera decorative rings, earpiece grilles, side keys, internal structural parts, etc.) represent the pinnacle of precision manufacturing in the consumer electronics field. Its core points revolve around "miniaturization", "high strength", "high precision" and "aesthetic integration", which are essentially different from ordinary plastic parts.

�� Key points analysis

1. Material selection: The ultimate balance between performance and cost

The requirements for materials of mobile phone components are extremely strict, and there are differences between internal and external ones.

The exterior structural components (such as the middle frame) have fully shifted from plastic to metal. The mainstream uses 6-series or 7-series aluminum alloys, which are precisely processed by CNC, then combined with the plastic antenna part through nano-injection molding technology, and finally undergo anodizing and coloring to achieve high strength and rich colors. For higher strength and heat dissipation, stainless steel or titanium alloy will be adopted.

Internal structural components and decorative parts: High-performance engineering plastics such as LCP and PPS are commonly used. They have an extremely low coefficient of thermal expansion, high heat resistance and good dielectric properties, making them suitable for manufacturing precision connectors, antenna mounts and camera rings, ensuring no deformation during high-temperature reflow soldering and no signal interference.

General structural components: For battery covers and certain internal brackets, glass fiber reinforced PC or PC/ABS alloys are used to strike a balance between strength, toughness and cost.

2. Structural design: Integrate all functions within a small space

The interior of a mobile phone is a "millimeter-level war", and the structural design must serve the entire machine.

Strict stacking tolerance: The thickness of each part and the assembly dimensions directly affect the overall thickness and waterproof performance of the machine. The design tolerance is usually ±0.05mm or even smaller.

To make way for the signal: The metal frame must be designed with plastic injection molding breaks for the antenna. If the back cover is made of glass or ceramic, the conductive coating design on its inner side should avoid shielding the antenna.

Strength and drop test orientation: The design of all clips and screw columns must pass strict drop tests and twist test simulations. For instance, the camera decorative ring not only needs to be aesthetically pleasing, but also its assembly structure with the lens and the main board must be capable of disperses the impact force from drops and protecting the fragile camera module.

3. Molds and Processes: Towards Micron-level Precision Manufacturing

The ultimate requirement for molds: The mold steel must be the highest grade mirror steel (such as S136, NAK80). To deal with extremely small and deep ribs and pins, a large amount of precision slow wire cutting and micro-hole electrical discharge machining are required. Exhaust design is of vital importance to prevent trapped air from causing a poor appearance.

The wide application of special processes

Nano injection molding: Micro-holes are chemically etched on the metal surface, and plastic is directly injected into them to achieve a firm bond between metal and plastic. This is the key technology for metal frame antennas.

In-mold injection: Pre-place the film (IMD) or metal sheet (IML) into the mold and inject it into a surface with exquisite patterns or textures in one go. No post-spraying is required, and it is wear-resistant and has a good texture.

Two-color/multi-color injection molding: Used for manufacturing seamless soft rubber side keys or logos of different colors.

4. Process Control and Inspection: Ensure consistency at the millions level with data

Fully automated production: In a 10,000-level dust-free workshop, mechanical arms complete the entire process from injection molding, cutting, inspection to packaging, avoiding scratches or contamination caused by human contact.

Full-process monitoring: Use in-mold sensors to monitor injection pressure and temperature in real time; 100% visual inspection is carried out through machine vision, automatically identifying defects such as scratches, dirt spots, and shrinkage.

Precision measurement: Use two-dimensional image measuring machines, three-dimensional measuring machines, and even industrial CT scans to measure key dimensions and assemblies to ensure zero discrepancies between batches.

5. Test verification: Simulate the most severe usage scenarios of users

The parts must pass more rigorous tests than the entire machine, including:

Environmental reliability testing: high and low temperature storage and cycling, damp heat testing, UV aging testing.

Chemical and abrasion tests: Corrosion tests for sweat, cosmetics, alcohol, etc., as well as RCA paper tape abrasion tests (for surface coatings).

Mechanical life test: Hundreds of thousands of insertion and extraction, as well as pressing tests of movable parts such as side keys and clips
