Ⅱ. Materials and Processes: Ensuring Quality from the Source
1. Material Selection and Advantages
We strictly select top-tier raw materials in the industry, covering both metal and non-metal categories to ensure material performance matches product requirements:
- Metal materials: Aluminum alloys (6061/6063/7075, lightweight and high-strength), stainless steel (304/316, corrosion-resistant), brass (C3604, high conductivity), titanium alloys (high-strength and low-temperature resistant), etc. (with material certification attached);
- Non-metal materials: ABS (good toughness), POM (self-lubricating), Teflon (high-temperature resistant), etc., meeting the needs of special scenarios.
Example: For instance, "PIN needles" are made of brass C3604 with gold plating, which increases conductivity by 30% and is suitable for high-frequency signal transmission scenarios (corresponding to CNC lathe product cases in the document).
2. Processing Technology and Equipment
| Processing Method | Core Equipment | Technological Advantages | Application Scenarios |
|---|---|---|---|
| CNC Turning | Yangmu 46-type turning-milling compound machine (Dongguan) | 3-axis linkage, supporting one-time forming of complex surfaces with precision ±0.01mm | Shafts, sleeves (e.g., connecting shafts) |
| CNC Milling | Taiqun 850-type 3+2 5-axis machining center (Dongguan) | Multi-surface synchronous processing, solving thin-walled part deformation with precision ±0.005mm | Complex structural parts (e.g., camera lens components) |
| Stamping Forming | Precision CNC turret punch press | High-speed stamping (80 times/minute), suitable for mass production of thin-sheet parts with precision ±0.1mm | Shield covers, shrapnels, etc. |
| Surface Treatment | Anodizing production line, salt spray tester | Supporting hard anodizing (film thickness 10-20μm), galvanizing (salt spray resistance ≥72 hours), gold plating (purity 99.9%), etc. | Enhancing corrosion resistance and aesthetics |
Equipment Advantages: All equipment is equipped with automatic bar feeders (Qiancheng Jinxiu KT series), realizing automated flow from raw materials to finished products, reducing manual errors, with a stable daily output of over 20,000 pieces (corresponding to the "daily production capacity of over 20,000 pieces" in the document).
