· Product Overview
This precision-engineered pin set is custom-manufactured from high-grade 304/316 stainless steel via advanced CNC turning and milling processes, featuring diverse configurations including grooved pins, pointed pins, flanged pins, and standard dowel pins. Designed for positioning, fastening, or mechanical linkage in industrial assemblies, these pins combine exceptional dimensional accuracy, high shear strength, and corrosion resistance. The precision-ground surface finish ensures smooth insertion and secure retention, while custom end features (flanges, points, grooves) cater to specialized mounting and alignment needs. Ideal for automotive, electronics, and precision machinery applications, this pin set delivers reliable performance in high-stress industrial environments.
· Core Specifications
| Specification | Details |
|---|---|
| Base Material | 304/316 Stainless Steel (standard, excellent corrosion resistance & high shear strength); optional carbon steel for cost-effective applications |
| Surface Finish | Precision ground (Ra ≤ 0.8μm, smooth & wear-resistant); optional passivation for enhanced corrosion resistance |
| Machining Process | CNC precision turning, milling, and grooving (conforming to ISO 2768-m / ISO 8734 precision pin standards) |
| Dimensional Tolerance | ±0.01mm for outer diameter (OD) and length; ±0.02mm for groove/flange position |
| Key Features | Diverse custom configurations (grooved, pointed, flanged, standard dowel), precision-ground smooth surface, high rigidity stainless steel construction, and corrosion-resistant finish |
· Application Scenarios
These precision pins serve critical roles across high-performance industries:
- Automotive & Transportation: Dowel pins for engine assembly, suspension components, and door hinges
- Electronic Enclosures: Positioning pins for PCB modules, heat sinks, and industrial control boxes
- Industrial Machinery: Linkage pins, guide pins, and dowel pins for gearboxes, conveyor systems, and jigs/fixtures
- Aerospace & UAVs: Lightweight positioning pins for avionics, payload mounts, and drone structural assemblies
- Medical Devices: Non-magnetic dowel pins for surgical instruments and diagnostic equipment (316L variant for biocompatibility)
- Consumer Electronics: Precision positioning pins for smartphones, laptops, and wearable devices
· Production Process Introduction
- Design & DFM Validation: Our engineering team optimizes pin dimensions, end features, and groove positions via Design for Manufacturability (DFM) analysis to ensure maximum strength and installation ease.
- Material Preparation: Premium stainless steel bar stock is cut to size and faced to create a clean starting surface for machining.
- Precision CNC Machining:
- Turning: The cylindrical profile is precision-turned to achieve tight OD tolerances and a smooth surface finish.
- Milling/Grooving: Custom end features (points, flanges, grooves) are milled or grooved to meet specific application requirements.
- Chamfering: All sharp edges are chamfered to facilitate easy insertion and prevent injury.
- Surface Finishing: The pins undergo brushing and passivation to enhance corrosion resistance and surface smoothness.
- Quality Inspection: 100% dimensional inspection via CMM and micrometer verifies OD, length, and feature alignment; a functional insertion test ensures secure retention.
- Final Packaging: Pins are sorted by size/type and packed in anti-static bags inside corrugated cartons to prevent scratching or misplacement during transit.
· Packaging and Shipping Methods
- Standard Packaging: Pins are sorted by specification and packed in anti-static PE bags, placed in labeled corrugated cartons. Bulk orders are secured on wooden pallets with plastic wrapping to prevent damage during long-distance transit.
- 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, and custom compartment trays are available to align with your independent store’s brand guidelines and inventory management needs.
· Process
· Frequently Asked Questions (FAQ)
What is your Minimum Order Quantity (MOQ)?
Our MOQ is flexible to suit your independent store's e-commerce needs:
- Prototypes/Samples:1 piece available for custom design validation.
- Production Runs: Starting at 100+ pieces for standard configurations. We specialize in low-volume, high-precision custom fabrication to match your online store’s demand.
What are your typical lead times?
- Prototype/Sample Orders: 7–10 business days from final CAD design approval (includes machining and finishing).
- Mass Production: 15–25 business days, depending on order volume, pin size, and custom feature requirements.
- Rush Service: Expedited production (4–6 days for samples) is available upon request for urgent restocks.
Can you accommodate full custom modifications?
Absolutely. We offer end-to-end customization to align with your independent store's product offerings:
- Size & Shape Customization: Custom overall length, outer diameter (OD), and end profiles to match your specific application.
- Feature Customization: Custom groove patterns, flange dimensions, pointed tips, or threaded ends for specialized fastening or alignment needs.
- Material Upgrades: Switch between 304 stainless steel (general corrosion resistance) or 316L stainless steel (medical/high corrosion environments) based on your application.
- Surface Finish Options: Custom plating (zinc/nickel), anodizing, or black oxide for enhanced durability or aesthetic appeal.
- Branding & Traceability: Laser engraving of logos, part numbers, or batch codes for full product traceability and inventory management.
