2. 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 that material performance matches product requirements
- Metal materials: Aluminum alloys (6061/6063/7075, lightweight, high strength), stainless steel (304/316, corrosion-resistant), brass (C3604, high conductivity), titanium alloys (high strength, low-temperature resistance), 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, and through gold plating treatment, their conductivity is increased by 30%, making them suitable for high-frequency signal transmission scenarios (corresponding to the CNC lathe product cases in the document)
2. Processing Technologies and Equipment
| Processing Method | Core Equipment | Technological Advantages | Applicable Scenarios |
|---|---|---|---|
| CNC Turning | Yangmu Model 46 Turning-Milling Composite Machine (Dongguan) | 3-axis linkage, supporting one-time forming of complex curved surfaces, 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 deformation issues of thin-walled parts, 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, precision ±0.1mm | Shield covers, shrapnel, etc |
3. Technical Difficulties and Solutions
Aiming at common pain points in precision processing, we have formed standardized solutions to enhance buyers' trust
| Technical Difficulty | Solution | Case Reference (products in the document) |
|---|---|---|
| Easy deformation of thin-walled parts | Using Taiqun T6 4-axis machining center, with stepwise cutting + cooling control, controlling deformation within 0.02mm | Aluminum alloy shell (wall thickness 0.5mm, precision ±0.01mm) |
| High-precision one-time forming | Star (Japan) sliding head lathe (5-axis linkage), reducing clamping times to avoid cumulative errors | Brass PIN needle (0.01mm precision, one-time forming) |
| Surface roughness requirement of Ra0.2 | Real-time monitoring with imported roughness meter, combined with ultra-precision polishing process to ensure surface finish | Sealing fasteners (for medical equipment) |
| Coordination of multiple processes for complex structures | DFM (Design for Manufacturability) intervention in advance to optimize process flow, shortening processing cycle by 30% | Semiconductor rotation axis (with non-standard threads + deep hole processing) |
4. Quality Control System
