Renewable Energy Manufacturing
Precision Machined Spacers and Components for Renewable Energy Infrastructure
SpacerMFG provides contract manufacturing services for OEMs and engineering firms developing renewable energy hardware. Based in Shenzhen, we produce precision spacers, bushings, sleeves, and custom turned components for demanding power generation and storage applications.
Direct-to-factory manufacturing
Built to your drawings, tolerances, material specifications, and production requirements.
Engineering support
Supporting renewable energy engineering
Renewable energy systems—from wind turbine gearboxes to solar tracking mechanisms and battery storage enclosures—require hardware that withstands vibration, thermal expansion, and mechanical stress.
Our manufacturing process begins with your technical drawings. We translate your specifications into high-performance components, ensuring that every spacer, standoff, and shaft integrates into your assembly without fitment issues.

Production capabilities
From precision turning to complex milled components
Our production capabilities support the small circular hardware and complex structural parts used throughout renewable energy equipment.
01 / CNC Turning
Precision CNC turning capabilities
Precision lathes manufacture circular components with tight control of outer diameters, inner diameters, and concentricity.
- Materials: Aluminum 6061/7075, stainless steel 303/304/316, brass, carbon steel, and engineering plastics.
- Part types: Spacers, sleeves, bushings, pins, shafts, and collars.
- Features: Chamfers, grooves, steps, and internal or external threading.
- Volume: Rapid prototypes through high-volume repeat orders.
02 / CNC Milling
Complex components with dimensional stability
Our milling department handles brackets, mounting blocks, and structural components for renewable energy housings and mounting systems.
- Capabilities: Pockets, slots, counterbores, and irregular profiles.
- Precision: Production to your specified GD&T requirements.
- Applications: Custom brackets and interface plates for energy equipment modules.
Ready for installation
Secondary processing and surface finishing
A component is only as good as its surface integrity. We perform secondary operations in-house or through qualified specialized partners so parts are ready for immediate installation.
Mechanical processing
Drilling, reaming, and precision grinding for improved surface finish.
Surface treatment
Anodizing for aluminum corrosion resistance, passivation for stainless steel, and nickel or zinc plating for steel protection.
Identification and traceability
Laser marking for part numbers, traceability, and maintenance labeling.
Material selection
Select the right specification for your application
Choosing the correct material and tolerance level is critical for long-term reliability in energy infrastructure. If you are evaluating material choices for a new design, our team can provide manufacturability feedback to help optimize production costs.
Aluminum spacers
Ideal for weight-sensitive applications or where non-magnetic properties are required.
Stainless steel spacers
Recommended for outdoor environments or installations exposed to corrosive elements.
Steel and brass
Used in high-load mechanical assemblies where structural rigidity is the priority.
Quality assurance
Quality control for industrial buyers
We manufacture strictly to your print. Before any batch leaves our facility, our quality process checks dimensions, threads, and surface finishes against your provided tolerances. Consistent quality helps OEM supply chains avoid downtime on the assembly line.
Supply partnership
Working with SpacerMFG
We partner with mechanical engineers, sourcing managers, and procurement teams that need a reliable manufacturing source in China. Our direct-to-factory model eliminates unnecessary intermediaries while supporting competitive pricing and clear communication.
