Metal Enclosure Series
1. Material Preprocessing: Establish a Quality Foundation
Premium materials (galvanized steel, stainless steel, copper, aerospace aluminum, aluminum alloy, iron etc.) undergo laser cutting blanking (precision ±0.1mm), plus mechanical deburring, chemical derusting, and surface cleaning. This eliminates impurities and internal stress, laying a high-precision base for subsequent processing.
2. CNC Core Processing: Critical Link for Precise Forming
CNC Bending: Imported CNC bending machines enable ±0.1° angular precision for any bending angle. Custom molds support one-step forming of complex folded lines and multi-curved enclosures, ensuring batch-to-batch bending consistency.
CNC Stamping/Milling: High-speed CNC punches realize precision forming of holes and slots; milling optimizes surface finish of enclosure edges and assembly interfaces, meeting strict tolerance requirements for precision instruments and medical devices.
3. Forming & Reinforcement: Boost Structural Stability
For complex structures, argon arc/spot welding delivers smooth, burr-free welds; custom fixtures prevent welding deformation. Integrated forming is applied to selected products, enhancing overall structural strength and impact resistance for outdoor/industrial harsh conditions.
4. Surface Treatment: Balance Protection & Aesthetics
Diversified solutions (anodizing, electrostatic spraying, electrophoresis, wire drawing) improve corrosion/scratch resistance and support brand-color customization, elevating end-product appearance and texture.
5. Precision Inspection & Assembly: Eliminate Defective Products
Core Inspection: 2D optical measuring instruments conduct 100% full inspection of dimensional tolerances (≤±0.05mm), geometric tolerances, and bending angles, with immediate correction for minor deviations.
Final Validation: Optional accessory assembly, IP rating testing, and electromagnetic shielding testing are provided; delivery is only permitted after full factory inspection and qualification.

FAQs
Customizing motherboards for kids’ devices centers on safety prioritization and child-centric scenario adaptability, adopting a standardized, targeted customization workflow to strike a seamless balance between functionality and protective capabilities. The detailed steps are as follows:
1. Define Core Product Requirements
First, map out the device’s intended use cases (e.g., early education devices, kids’ smartwatches, educational toys), functional modules (positioning, voice interaction, sensors), and safety benchmarks. Outline kid-specific safety requirements—including low radiation, interfaces compatible with food-grade materials, and short-circuit prevention—while validating compliance with relevant children’s safety certifications (e.g., China Compulsory Certificate (CCC) for children’s products).
2. Solution Customization & Prototype Development
Based on the defined requirements, engineers incorporate low-power chips into the motherboard architecture to extend battery life, integrate anti-misoperation circuit safeguards, and minimize the motherboard footprint to align with the compact form factors of kids’ devices. Following the finalization of the initial solution, a prototype motherboard is rapidly fabricated to validate functional compatibility, safety, and stability.
3. Testing & Mass Production Launch
Comprehensive multi-dimensional testing is imperative, covering safety voltage withstand tests, drop and shock resistance evaluations, and functional compatibility assessments to ensure full adherence to children’s product safety standards. Once all tests are passed, mass production can kick off. Additionally, dedicated after-sales technical support is provided to guarantee the long-term reliable operation of the motherboards.
The entire process is anchored in the unique needs of children’s usage scenarios, not only meeting the device’s functional demands but also fortifying a robust safety barrier.
