· Production Process Introduction

1. Design & Engineering Validation: Our engineering team finalizes spline specifications, flange dimensions, and anti-rotation features, and verifies torque capacity and alignment performance via finite element analysis (FEA).
2. Raw Material Preparation: Premium stainless steel bar stock is sourced from certified suppliers, with spectrometric analysis to confirm material composition and mechanical properties.
3. Precision CNC Turning: CNC lathes form the dual-flanged cylindrical body, facing flanges and machining the outer profile to tight dimensional tolerances.
4. Internal Spline & Feature Machining: Internal splines are precision-broached or milled to meet pitch and tolerance requirements, followed by milling of anti-rotation locking tabs.
5. Deburring & Finishing: Components undergo meticulous deburring to remove sharp edges, followed by optional passivation/electropolishing to enhance corrosion resistance.
6. Quality Inspection: 100% inspection is performed via CMM (Coordinate Measuring Machine) and spline gauges to verify dimensional accuracy, spline fit, and functional compliance.
7. Final Packaging: Components are cleaned, wrapped in anti-corrosion film, and secured in custom foam inserts to prevent surface damage during transit.

· Packaging and Shipping Methods

• Standard Packaging: Each bushing is individually wrapped in anti-scratch PE film, then placed in custom-cut EPE foam trays inside reinforced corrugated cartons to prevent collision and surface wear.
• Shipping Options:
  • Express Delivery (3–7 Business Days): DHL/FedEx/UPS for prototype and small-batch orders (full tracking provided).
  • Standard Sea Freight (25–40 Business Days): Cost-effective FCL/LCL options for large-volume production orders, with full customs documentation support.
• Custom Packaging: Branded labeling, barcoding, serialized part marking, and custom crate designs are available to align with inventory management and brand guidelines.

· Frequently Asked Questions (FAQ)

What is your Minimum Order Quantity (MOQ)?

What are your typical lead times?

• Prototyping/Sample Orders: 7–12 business days from final CAD design approval to shipment.
• Mass Production: 15–25 business days, depending on order volume, spline complexity, and surface treatment requirements.
• Rush Service: Expedited production (4–7 days for prototypes) is available upon request for urgent projects.

Can you accommodate custom modifications?

• Material Customization: 316L stainless steel for corrosion-resistant environments, or alloy steel for high-torque applications.
• Design Modifications: Custom spline specifications (module, tooth count), flange dimensions, anti-rotation tab designs, or additional mounting features (e.g., threaded holes, keyways).
• Surface Finish Options: Passivation, electropolishing, or bead blasting to enhance corrosion resistance or aesthetic appeal.
• Branding & Traceability: Laser engraving of part numbers, batch codes, or logos for full product traceability.
