Precision Engineering to Your Specifications
We do not supply off-the-shelf catalog parts. Our facility in Dongguan is configured for custom manufacturing, meaning every component is machined to your specific drawing, 3D model, or physical sample. We manage the entire production cycle for components requiring tight dimensional control.
Made-to-print production for OEMs, distributors, and MRO providers — from engineering sample to full production run.
Bore and Shaft Fits
Machining to H6/H7 or h6/h7 tolerances.
Geometric Control
Maintaining concentricity, roundness, and runout down to 0.01 mm.
Surface Integrity
Achieving surface finishes as fine as Ra 0.2 μm.
Complex Features
Incorporating keyways, snap-ring grooves, threads, and flanged profiles.
Private Label Manufacturing for Distributors
For industrial distributors and component suppliers, we provide white-label manufacturing services. We produce sleeves according to your proprietary designs, allowing you to maintain brand consistency across your product range.
We support your supply chain with flexible production volumes, ranging from small-batch engineering samples to high-volume production runs. Our team ensures that all components meet your quality standards, including material certification and dimensional inspection reports, before they are packaged for your end customers.
- White-label production to your proprietary designs
- Flexible volumes from engineering samples to high-volume runs
- Material certification and dimensional inspection reports
Manufacturing Capabilities
Our Dongguan facility integrates primary and secondary operations to reduce your need for multi-vendor management.
Machining
CNC turning, CNC milling, and precision drilling.
Grinding
OD/ID grinding and centerless grinding for high-precision fits.
Secondary Operations
Heat treatment (quenching, tempering, nitriding, induction hardening) and specialized coatings (PVD/DLC, hard chrome, electroless nickel, passivation).
Materials
Stainless steel (304, 316, 17-4PH), carbon/alloy steels (4140, 4340), tool steels (52100), copper alloys, and nickel-based superalloys.
Solving Common Manufacturing Challenges
Precision sleeves often suffer from distortion or failure if not produced with the correct process. We address specific technical hurdles during the quoting and engineering phase.
Thin-Wall Distortion
We use specialized fixturing and sequential machining processes to prevent deformation in thin-walled spacer or wear sleeves.
Material Hardness
We manage the transition between raw material machining and post-heat-treatment grinding to ensure final dimensions remain within tolerance after hardening.
Fit Consistency
By utilizing calibrated bore gauges and CMM inspection, we ensure that every piece in your production run maintains the required fit for your assembly.
Industries Served
We support sectors that rely on high-performance rotating equipment.
Pumps & Fluid Handling
Pump shaft sleeves, mechanical seal sleeves, and wear sleeves.
Power Transmission
Motor shafts, bearing sleeves, and gearbox components.
Mining & Heavy Machinery
Hardened wear-resistant sleeves designed for harsh environments.
Automation
Guide sleeves and precision spacers for industrial machinery.
Quality Control and Documentation
Every order is processed with rigorous inspection protocols. Our quality department utilizes CMMs, profile projectors, and digital surface roughness testers to verify that parts comply with your print.
For projects requiring traceability, we provide full material certifications and First Article Inspection (FAI) reports upon request.
