· 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 and precision turning for one-piece forming, ensuring uniform flange flatness and concentricity.
• Precision Tolerance: ±0.01mm for critical dimensions, ensuring perfect alignment with mating components; flange flatness ≤0.02mm.
• Surface Finish: Precision milled (Ra ≤ 1.6μm), with optional passivation or electropolishing for enhanced corrosion resistance.
• Structural Features: Integrated mounting flange with evenly spaced bolt holes, precision internal bore, and seamless one-piece design.
• Quality Certification: ISO 9001 certified, with full dimensional inspection via CMM (Coordinate Measuring Machine).

· Application Scenarios

• Industrial Automation: Robotic arm mounting flanges, conveyor system alignment sleeves, and sensor mounting bases.
• Fluid Handling Equipment: Pump and valve flanges, fluid transfer ports, and pressure vessel connections.
• Medical Devices: Surgical instrument mounting flanges, diagnostic equipment housings, and implantable device components (biocompatible materials available).
• Marine & Offshore: Subsea equipment flanges, corrosion-resistant fluid transfer sleeves, and offshore platform mounting bases.
• Aerospace: Lightweight structural flanges, UAV component mounting bases, and aircraft system connections.

· 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 cylindrical profile and flange.
3. Precision Finishing: Mill the mounting flange, drill bolt holes, and machine the internal bore to 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, flange flatness, and bore concentricity.
7. Cleaning & Packaging: Ultrasonically clean the sleeve to remove machining debris, then package for shipment.

· Packaging and Shipping Methods

Packaging

• Individual Sleeve: 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.
