• Industrial Automation: High-pressure fluid system nozzles, sensor mounting shafts, and robotic tool changer connection points.
• Biopharmaceutical Processing: High-purity fluid transfer components for drug manufacturing and laboratory equipment.

· Production Process Introduction

1. Raw Material Preparation: Cut certified medical-grade 316 stainless steel bars to exact length and diameter.
2. 5-Axis CNC Turning: Use high-precision CNC lathes to machine the multi-stepped profile, flanged base, and sealing grooves in a single setup for maximum concentricity.
3. Precision Drilling & Grooving: Create fluid holes and O-ring grooves with micron-level accuracy to ensure leak-free sealing.
4. Deburring & Polishing: Remove sharp edges and achieve a smooth surface finish to prevent fluid turbulence and bacterial adhesion.
5. Passivation Treatment: Apply a chemical passivation process to enhance corrosion resistance and biocompatibility.
6. Quality Inspection: Perform CMM dimensional scanning, pressure leak testing, and surface roughness analysis to verify compliance with medical-grade standards.

· Packaging and Shipping Methods

• Packaging:
  • Individual Components: Sealed in sterile, anti-static, moisture-proof blister packs to maintain medical-grade cleanliness and protect precision surfaces.
  • Bulk Orders: Packed in foam-lined, partitioned stainless steel containers (prevents contamination, deformation, and scratch damage).
• Shipping Options:
  • Express Delivery (DHL/FedEx): 2–4 business days for urgent medical device orders, with temperature-controlled shipping available.
  • Air Freight: 7–10 business days for medium-batch production runs.
  • Sea Freight: 20–25 business days for large-volume bulk orders.All shipments include full traceability documentation and compliance certificates.
