High-Precision Stainless Steel PIN Needle for Gold-Plated Drilling and Broaching
I. Core Product Value
Text Description:
Focus on solving three major pain points in precision parts processing: "high-precision assembly jamming, difficulty in processing complex structures, and poor multi-scenario adaptability". We support customization with over 20 materials such as stainless steel (SUS304/316), aluminum alloy (6061/7075), and titanium alloy, with precision up to 0.01mm (some parts up to 0.007mm). Our products cover more than 10 fields including consumer electronics, medical equipment, and semiconductors. Relying on a team with 20 years of experience and our own factory, we provide a full-link service of "DFM design optimization - precision processing - full inspection and delivery", with a daily production capacity of over 20,000 pieces and guaranteed short delivery times.

Detailed Description |
Buyer Value |
|
Material Selection |
Metals: Stainless steel (SUS303/304 for corrosion resistance, 316 for medical grade), aluminum alloy (6061 for general use, 7075 for high strength), brass (C3604 for conductivity), titanium alloy (high strength and lightweight); |
Match scenarios on demand (e.g., 316 stainless steel for medical use to prevent bacteria, titanium alloy for semiconductors to resist deformation) |
|
Precision Standards |
Dimensional accuracy: ±0.01mm (±0.007mm for high-precision parts); |
Ensure zero clearance in assembly and reduce debugging costs (e.g., 0.01mm precision of camera components ensures stable imaging) |
|
Processing Technology |
CNC lathe/milling machine (supporting 5-axis linkage), laser cutting, stamping, die-casting, wire cutting; |
Overcome traditional process difficulties (e.g., one-time forming of semiconductor rotating shafts without burrs) |
|
Surface Treatment |
Regular: Anodizing (natural/black/colored), chrome plating (Cr(NO3)3), zinc plating, sandblasting, polishing; |
Improve performance and appearance (e.g., anodizing of medical accessories for corrosion resistance, gold plating of electronic connectors to reduce contact resistance) |
|
Color Options |
Metal original color, anodized color (customized by Pantone color number), spray color (anti-static/high-temperature resistant coating) |
Match customer's product appearance design and meet brand unity needs (e.g., custom brand-specific colors for consumer electronics casings) |
III. Processing Capabilities and Equipment Guarantee
Text Description:
Our own factory is equipped with cutting-edge equipment to ensure stable processing of complex parts:
· Core equipment: Over 20 sets of equipment including high-precision CNC lathes (repeat positioning accuracy ±0.005mm), 5-axis linkage machining centers (positioning accuracy ±0.003mm), fiber laser cutting machines (cutting accuracy ±0.1mm), and 2.5D measuring instruments (detection accuracy 0.001mm);
· Technological breakthroughs: Support anti-deformation processing of thin-walled parts (minimum wall thickness 0.5mm), deep cavity non-chatter processing (0.01mm accuracy for small holes with depth 25mm), and burr-free treatment under 70x magnification, solving the industry pain points of "insufficient precision and easy deformation".

IV. Full-Process Quality Assurance System
Text Description:
With the goal of "zero defects", we have established a full-link quality control system:
1. Source control: Raw materials are from certified suppliers (material certificates provided), and their composition is tested by a spectrometer before storage to eliminate inferior base materials;
2. In-process control: Quality inspection nodes are set for each process (e.g., full inspection of dimensions with 2.5D measuring instruments after CNC processing), and 100% manual re-inspection for key parts in medical/semiconductor fields;
3. Outgoing control: Final products must pass salt spray tests (corrosion resistance), hardness tests (mechanical properties), and 70x magnifier inspection for burrs, with detailed quality inspection reports attached (supporting third-party testing);
4. Certification endorsement: Certified by ISO 9001 and IATF 16949, with over 10 utility model patents, meeting strict standards of the medical and automotive industries.
