Hansheng Automation (Dongguan) Co., Ltd. is one of the most experienced manufacturers and suppliers of bracket link in China. If you're going to wholesale bulk cost-effective bracket link made in China, welcome to get pricelist and quotation from our factory. Also, customized service and OEM&ODM service are available.
Why Choose Hansheng Automation?
Are you struggling to find a supplier who can handle both large-scale casting and micron-level precision machining? Most foundries lack finishing capabilities, while machine shops lack raw material control.
We provide a complete turnkey solution for Bracket Links and
structural connection parts. Leveraging our expertise in manufacturing high-precision transmission components (like Harmonic Drives and Cam Indexers), we bring "Gear-Class Precision" to structural castings. Whether you need a massive ductile iron bracket for heavy machinery or a lightweight aluminum link for automation, we deliver ready-to-assemble components with tolerances as tight as ±0.005mm.
Key Product Features
Unmatched Machining Precision
Unlike standard castings with loose tolerances, our bracket links are processed in the same workshop as our precision gearboxes.
Capability: Powered by Taesin CNC Milling and Brother CNC Lathes, we achieve ±0.005mm in milling and turning, and ±0.002mm in grinding.
Benefit: Perfect fit for bearings, shafts, and pins without any additional rework on your assembly line.
Large-Scale & Heavy Duty Capacity
We are equipped to handle the big jobs. Our foundry capabilities extend to 3800 × 1500 × 1200mm, and our Horizontal Machining Centers can process parts up to 2100 × 1060mm.
Benefit: Ideal for construction machinery, mining equipment, and large industrial frames.
Diverse Casting Processes
Sand Casting: Cost-effective for large iron/steel brackets.
Lost Foam Casting: Perfect for complex geometries with no draft angles.
Gravity Casting: High-density options for aluminum alloy links.

Quality Assurance
Since we manufacture precision gears (ISO Level 5), our inspection standards for structural brackets are exceptionally rigorous.
CMM Inspection
Verification of all spatial dimensions and geometric tolerances (GD&T).
NDT (Non-Destructive Testing)
Ultrasonic and Magnetic Particle Inspection to ensure no internal cracks or porosity in the casting.
Equipment
Gear Inspection Machines (used for complex profiles), Hardness Testers.
Applications
Heavy Construction Machinery
Bucket links, boom pivots, and chassis brackets for excavators and loaders.
Industrial Automation
Robot base connecting arms, precision rail supports (requiring high flatness).
Power Transmission
Mounting brackets for planetary gearboxes and motors.
Agricultural Equipment
High-strength linkage arms for tractors and harvesters.
FAQ
Q: Do you do the machining in-house or outsource it?
A: We perform 100% of the precision machining in-house. We own advanced equipment including Horizontal Machining Centers, Brother CNC Lathes, and Kashifuji Gear Skiving machines. This ensures we have full control over the quality and schedule.
Q: My bracket link requires very tight tolerance on the bearing bore. Can you achieve it?
A: Yes. Our expertise lies in high-precision components. We can achieve bore tolerances of H6/H7 and position tolerances within ±0.005mm using our high-end CNC centers.
Q: What 3D file formats do you accept for quotation?
A: We accept STEP (.stp), IGES (.igs), X_T, and SolidWorks files, along with 2D PDF drawings for tolerance specifications.
Q: Can you handle low-volume orders or prototypes?
A: Yes, we support rapid prototyping (via CNC machining from solid block or 3D printed sand molds) before moving to mass production casting.
