· Product Overview

· Core Specifications

Material & Process Standards

• Raw Material: 304 Stainless Steel (general industrial grade) or 316 Stainless Steel (corrosion-resistant grade), offering excellent tensile strength, machinability, and resistance to harsh chemicals and saltwater.
• Processing Technology: 5-axis CNC milling, precision turning, threading, and contouring for one-piece forming of complex geometries.
• Precision Tolerance: ±0.01mm for critical dimensions, ensuring perfect alignment and leak-free performance.
• Surface Finish: Precision polished (Ra ≤ 0.8μm), with optional passivation or electropolishing for enhanced corrosion resistance.
• Structural Features: Integrated threaded shafts, flanged mounts, precision internal/external bores, and specialized drive features (serrated/hexagonal) for secure installation.
• Quality Certification: ISO 9001 certified, with full dimensional inspection via CMM (Coordinate Measuring Machine).

· Application Scenarios

• Industrial Automation: Robotic end-effector connectors, fluid transfer fittings, and actuation components.
• Fluid Handling Equipment: Hydraulic/pneumatic system valves, fluid transfer ports, and pressure control fittings.
• Medical Devices: Surgical instrument connectors, diagnostic equipment fluid ports, and implantable device components (biocompatible materials available).
• Marine & Offshore: Subsea equipment fasteners, corrosion-resistant fluid connectors, and offshore platform actuation components.
• Aerospace: Lightweight actuation components, fluid system connectors, and aircraft system fasteners.

· Production Process Introduction

1. Raw Material Preparation: Cut 304/316 stainless steel bars to the required dimensions.
2. CNC Rough Machining: Remove excess material to form the basic profile of the fastener.
3. Precision Finishing: Mill the complex contours, drill precision bores, and machine threads with tight tolerances.
4. Deburring & Polishing: Remove all sharp edges and burrs, and polish critical surfaces to ensure smooth operation.
5. Surface Treatment (Optional): Apply passivation or electropolishing for enhanced corrosion resistance.
6. Quality Inspection: Use CMM to verify dimensions, thread fit, and bore concentricity; perform pressure testing for fluid components.
7. Cleaning & Packaging: Ultrasonically clean the fasteners to remove machining debris, then package for shipment.

· Packaging and Shipping Methods

Packaging

• Individual Fastener: Wrapped in anti-static PE bags and protected with foam padding to prevent scratches and deformation.
• Bulk Orders: Packed in foam-lined partitioned cartons to avoid friction and damage between parts.
• Outer Packaging: Export-grade moisture-proof and shock-proof corrugated boxes, suitable for long-distance international transportation.

Shipping Methods

• Express Delivery (DHL/FedEx/UPS): 3–7 working days for samples, prototypes, and small-batch urgent orders.
• Air Freight: 7–15 working days for medium-batch production runs.
• Sea Freight: 20–35 working days for large-volume bulk orders.
• All shipments include real-time tracking and reinforced packaging for precision components.
