· Product Overview
These precision-engineered U-shaped mounting brackets are custom CNC-machined from high-grade 6061 aluminum alloy (or SPCC cold-rolled steel), featuring a robust U-profile structure with top/bottom mounting plates and a curved central body. Finished with a durable black powder coating, they provide stable, adjustable support for motors, sensors, and industrial equipment. The multi-hole design (including slotted adjustment holes) allows flexible positioning and secure installation, while the rigid metal construction ensures long-term stability in dynamic industrial environments. Ideal for precision positioning and load-bearing mounting applications, they deliver exceptional dimensional accuracy and corrosion resistance.
· Core Specifications
| Specification | Details |
|---|---|
| Base Material | 6061 Aluminum Alloy (standard, lightweight & high-strength); SPCC Cold-Rolled Steel (cost-effective, high-load capacity) |
| Surface Finish | Black powder coating (standard, corrosion-resistant & wear-resistant); optional clear anodizing (aluminum) or electro-galvanizing (steel) |
| Dimensional Tolerance | ±0.02mm for mounting hole position; ±0.1mm for overall profile; conforming to ISO 2768-m |
| Core Manufacturing Processes | Laser cutting / CNC stamping, precision bending, drilling/tapping, slotted hole milling, and powder coating |
| Key Features | U-shaped rigid structure, slotted adjustment holes for flexible positioning, multi-point mounting holes for secure fixation, corrosion-resistant powder coating, and lightweight high-strength design |
· Application Scenarios
These U-shaped mounting brackets serve critical roles across precision industrial systems:
- Industrial Automation: Mounting brackets for stepper motors, servo motors, and gearboxes in automated production lines
- Sensor & Detection Devices: Fixed support for photoelectric sensors, proximity sensors, encoders, and measuring instruments
- Robotics & Mechanical Arms: Positioning brackets for end-effectors, sensor modules, and auxiliary components of robotic arms
- Electronic & Test Equipment: Stable mounting for precision measuring devices, laboratory instruments, and portable testing tools
- Automotive & Medical Devices: Lightweight mounting brackets for in-vehicle sensors and small medical equipment
- Conveyor & Assembly Systems: Adjustable mounting supports for conveyor line positioning jigs and material handling components
· Production Process Introduction
- Design & DFM Validation: Our engineering team optimizes mounting hole patterns, bend angles, and slotted hole positions via Design for Manufacturability (DFM) analysis to ensure installation flexibility and structural integrity.
- Material Preparation: Premium aluminum/steel sheet stock is cut to size and deburred to create a clean base for fabrication.
- Precision Forming: Components are laser-cut/stamped into the U-shaped profile, followed by CNC bending to form the rigid curved structure.
- Secondary Machining: Drilling, tapping, and milling operations create multi-point mounting holes and slotted adjustment holes with tight positional tolerance.
- Surface Treatment: Parts undergo degreasing, phosphating, and black powder coating, followed by high-temperature curing to form a durable, corrosion-resistant finish.
- Quality Inspection: 100% dimensional inspection via CMM and visual coating check verifies compliance with design specifications.
- Final Packaging: Brackets are individually wrapped in PE bags, secured in EPE foam trays, and packed in reinforced corrugated cartons to prevent scratching and deformation.
· Packaging and Shipping Methods
- Standard Packaging: Each bracket is wrapped in anti-scratch PE film, placed in custom-cut EPE foam trays, and packed in reinforced corrugated cartons. For large-volume orders, wooden crates are used for extra protection.
- 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 customer-specific packaging designs are available to align with inventory management and brand guidelines.

· Frequently Asked Questions (FAQ)
What is your Minimum Order Quantity (MOQ)?
Our MOQ is flexible: 1 piece for prototype and custom one-off projects, with volume pricing starting at 50+ pieces for production runs. We specialize in both low-volume, high-precision custom manufacturing and large-scale OEM production.
What are your typical lead times?
- Prototype/Sample Orders: 7–10 business days from final CAD design approval (includes fabrication and powder coating).
- Mass Production: 15–25 business days, depending on order volume, bracket complexity, and surface finish requirements.
- Rush Service: Expedited production (4–6 days for samples) is available upon request for urgent projects.
Can you accommodate full custom modifications?
Absolutely. We offer end-to-end customization to meet your exact application requirements:
- Material Customization: Switch between 6061 aluminum (lightweight) and SPCC steel (high-load) based on your performance needs.
- Design Modifications: Custom mounting hole patterns, slotted hole sizes, bend angles, and overall dimensions to match your equipment.
- Surface Finish Options: Custom powder coating colors, anodizing, or galvanizing to enhance corrosion resistance or align with brand aesthetics.
- Branding & Traceability: Laser engraving of part numbers, batch codes, or logos for full product traceability and inventory management.
