Precision Production Sleeve Manufacturing
SleeveMFG specializes in the production of custom-machined metal sleeves and rotational components. We operate as a dedicated manufacturing partner for OEMs, MRO repair facilities, and industrial distributors, transforming your engineering drawings into precision-machined parts.
Unlike general-purpose CNC shops, our facility in Dongguan, China, is optimized specifically for the geometric and dimensional requirements of sleeve components, including tight ID/OD concentricity, thin-wall stability, and high-precision surface finishes.
Custom Machined Sleeves to Your Specification
We manufacture components directly from 2D drawings, 3D models (STEP, IGES, SolidWorks), or physical samples. Our production workflow is designed for projects requiring strict adherence to geometric dimensioning and tolerancing (GD&T).

Why Partner with SleeveMFG
Our focused expertise in sleeve and rotational component manufacturing delivers reliable quality, reduced risk, and flexible production for every type of buyer.
For OEMs & Equipment Manufacturers
We provide consistent, repeatable quality from prototype to mass production. By focusing on sleeves and rotational parts, we mitigate common manufacturing risks such as wall distortion and runout issues, ensuring your production line remains uninterrupted.
For MRO & Repair Companies
If you are replacing obsolete or worn components, we can reverse-engineer sleeves from your provided samples or worn parts. We support small-batch production, allowing you to source replacements without the need for large inventory commitments.
For Sourcing & Procurement
We offer a streamlined RFQ process with transparent material certification and inspection reporting. Located in Dongguan, our position within the manufacturing supply chain allows us to maintain competitive pricing while meeting the technical documentation standards required by international buyers.
