· Product Overview

· Core Specifications

• Material: 304 Stainless SteelFood-safe (compliant with FDA 21 CFR 175.300), corrosion-resistant (72-hour salt spray test passed), tensile strength ≥515 MPa.
• Manufacturing Standard: ISO 9001-Certified
  • Key Processes: CNC Milling (block profile + through holes) → Precision Tapping (threaded holes) → Deburring (smooth edges) → Surface Passivation (corrosion protection).
  • Standard Parameters:
    • Threaded Holes: M5/M6 (customizable to Metric/Imperial standards)
    • Through Holes: 8–10mm (matched to routing/part dimensions)
    • Side Set-Screw Holes: M3 (for secure assembly positioning)
    • Dimensional Tolerance: ±0.02mm (ensures leak-free fit and component alignment)
  • Surface Finish: Passivated polished (non-porous, easy to clean, rust-resistant).

· Application Scenarios

• Pneumatic/Hydraulic Systems: Air/gas line distribution manifolds, low-pressure fluid routing blocks, or valve mounting hubs.
• Food & Beverage Processing: Sanitary fluid transfer manifolds (304 SS meets food-contact standards) or packaging machine component mounts.
• Industrial Automation: Equipment component mounting blocks, robotics fluid control hubs, or conveyor system part integration.
• Laboratory Instruments: Sample fluid routing blocks, test equipment component mounts, or sterile system integration parts.
• Mechanical Assemblies: Multi-component mounting hubs, shaft positioning blocks, or custom jig structural components.

· Production Process Introduction

1. Raw Material Sourcing: Procure certified 304 stainless steel billets (traceable to quality and material standards).
2. CNC Milling: Use precision 3-axis CNC mills to shape the rectangular block, drill through holes, and machine side set-screw holes.
3. Precision Tapping: Tap the top threaded holes (matched to target fastener/connection sizes for leak-free fit).
4. Deburring & Finishing: Remove sharp edges from holes, edges, and threads (prevents assembly damage and ensures safe handling).
5. Surface Passivation: Apply a chemical passivation treatment to enhance 304 SS’s natural corrosion resistance.
6. Quality Inspection: Conduct CMM (Coordinate Measuring Machine) scans (dimensional accuracy) + thread gauge checks + leak-testing (for fluid applications).

· Packaging and Shipping Methods

• Packaging:
  • Individual Units: Wrapped in anti-scratch protective film + sealed in moisture-proof plastic bags (preserves passivated finish).
  • Bulk Orders: Packed in foam-lined partitioned boxes (prevents hole deformation/thread damage) + moisture-absorbing desiccants.
• Shipping Options:
  • Express Delivery (DHL/FedEx: 3–5 business days for sample orders).
  • Air Freight (7–10 business days for small-batch production).
  • Sea Freight (20–25 business days for bulk orders).All shipments include full tracking and damage/leak insurance.

· Frequently Asked Questions (FAQ)

• MOQ (Minimum Order Quantity): 500 pieces for standard hole/dimension configurations; 200 pieces for custom designs (with valid technical drawings).
• Lead Time: Standard lead time is 7–10 working days (includes CNC machining and passivation); expedited production (5–7 working days) is available for urgent orders (additional fees apply).
• Customization Capability: Full customization is supported—we can adjust block dimensions, hole sizes/positions (threaded/through), add additional ports, or switch to 316 stainless steel (for extreme corrosion environments) based on your requirements. Our engineering team validates designs for fluid flow (if applicable) and component fit.
