Made-to-print CNC manufacturing
Precision Frame Spacers and Custom CNC Components
SpacerMFG provides contract manufacturing for custom frame spacers, sleeves, bushings, and precision turned parts. Based in Shenzhen since 2013, we work directly from customer-supplied drawings to meet specific tolerance, material, and application requirements.
From rapid prototypes to high-volume repeat production, we support OEMs and industrial equipment manufacturers with components designed to fit the first time.
2013
Shenzhen manufacturing base
Print-led
Production from your drawings
1 to high volume
Prototype through repeat runs
Engineering-led production
Clear communication on tolerances, materials, certifications, and lead times.
Component portfolio
Precision spacers made to your print
We produce structural and mounting components with the dimensions, materials, and tolerances your assembly requires.
Precision spacers
Custom OD, ID, length, and tight tolerances.
Spacer sleeves
Controlled wall thickness for structural alignment.
Stepped and flanged
Multiple diameters and specialized flange profiles.
Threaded spacers
Internal and external threading for rapid fastening.
Standoffs
Male-female or female-female configurations for electronics and chassis mounting.
Technical capability
CNC turning for consistent cylindrical components
Our CNC turning department is optimized for cylindrical components. Modern turning centers support consistency across large production runs while maintaining adherence to your technical specifications.
Typical turned parts
Spacers, sleeves, bushings, pins, shafts, and collars.
| Parameter | Specification |
|---|---|
| Materials | Aluminum, stainless steel, carbon steel, brass, copper, engineering plastics |
| Geometry | OD/ID profiles, steps, grooves, chamfers, threads |
| Tolerances | Per drawing requirements |
| Production | Prototype, low-volume, and high-volume repeat runs |
Beyond turning
Complex components in a complete workflow
CNC milling and secondary processing help prepare components with complex profiles and finished surfaces for immediate installation.
CNC milling
Brackets, blocks, and mounting hardware with pockets, slots, cross-holes, counterbores, and irregular profiles.
Dimensional finishing
Grinding for dimensional accuracy, polishing for surface condition, and deburring for safe assembly.
Protection and ID
Anodizing, passivation, nickel or zinc plating, black oxide, and laser marking for part numbers or batch codes.
Application guidance
Select the right spacer for your application
Material and geometry choices affect frame stability, joint performance, and equipment longevity.
Lightweight assemblies
Aluminum spacers and standoffs suit robotics and electronic instrument housings where weight reduction is a priority.
High-load industrial machinery
Steel or stainless steel spacers handle high torque and vibration, helping prevent joint failure under operational stress.
Corrosive environments
Stainless steel or plated components help prevent oxidation in medical, laboratory, and outdoor equipment.
Built for engineering and sourcing teams
A straightforward path from drawing to production
We partner with mechanical engineers, design teams, and procurement managers who require reliable, made-to-print manufacturing. Your drawing and material specification provide the starting point; our manufacturing expertise helps deliver parts that fit your assembly the first time.
Share your requirements
Send drawings, material specifications, tolerance requirements, and target volume.
Review manufacturability
We assess the RFQ and align production details, finishing, certifications, and lead times.
Produce repeatable parts
Prototype, low-volume, or repeat production is managed against your technical specifications.
