Precision components for electrical equipment
Precision Machined Spacers and Components for Electrical Equipment
Reliable mechanical integration is critical in electrical equipment assembly. SpacerMFG provides precision-engineered components manufactured strictly to your technical drawings, from insulating standoffs to structural spacers for control panels and power distribution units.
Since 2013
Based in Shenzhen
Made to print
Built to your drawings
01
Drawing-led production
Every project begins with a review of your drawings, material specifications, and tolerance requirements.
02
Prototype to volume
Support is available for small prototype batches as well as production runs of thousands of precision components.
03
Application-focused materials
Select from aluminum, stainless steel, brass, copper, and carbon steel to suit structural, thermal, and electrical requirements.
Component portfolio
Custom spacers built to your specifications
Electrical assemblies often require specific spacing, alignment, and clearance to meet safety and performance standards. We manufacture custom spacers that match your exact material and dimensional requirements.
Precision spacers
Custom outside diameter, inside diameter, and length tolerances for tight-fit assemblies.
Stepped spacers
Multi-diameter profiles for complex mounting configurations and controlled component positioning.
Threaded spacers
Internal or external threading for secure hardware mounting within electrical assemblies.
Flanged spacers
Designed for improved surface contact and load distribution inside electrical housings.
Manufacturing capability
CNC turning and milling for consistent geometry
Our facility handles both high-volume production and low-volume prototyping. Advanced CNC turning and milling centers support rigorous control over geometry and surface integrity.
Turning operations
We produce cylindrical components including sleeves, bushings, pins, and shafts. Precision drilling, reaming, and threading help achieve the concentricity and fit required for electrical equipment enclosures and internal mounting.
Milling operations
For brackets, blocks, and custom-profiled parts, milling delivers pockets, slots, counterbores, and precise mounting holes in the materials your application requires.
Suitable applications
Built for demanding electrical assemblies
- ● Control panels and electrical housings
- ● Power distribution units and industrial equipment
- ● Internal mounting and component alignment
- ● Brackets, blocks, sleeves, bushings, pins, and shafts
Material and finish selection
Configure parts for their working environment
Choosing the correct material and final treatment is essential for longevity, safety, corrosion resistance, and performance in electrical environments.
Aluminum
Lightweight and corrosion-resistant for electronics and instrumentation spacing.
Stainless steel
High strength with oxidation resistance for demanding environments.
Brass and copper
Preferred where specific electrical or thermal conductivity is required.
Carbon steel
A standard choice for structural applications in heavy-duty machinery and power equipment.
Finishing and secondary operations
Anodizing
Durable, non-conductive finish for aluminum spacers.
Passivation
Helps prevent surface contamination on stainless steel parts.
Plating
Nickel or zinc plating for corrosion resistance and aesthetics.
Black oxide
Cost-effective treatment for steel internal assemblies.
Laser marking
Part identification and traceability for complex systems.
