As your strategic Original Equipment Manufacturing (OEM) partner, HS Metal Spinning specializes in high-precision tolerance metal spinning. In precision engineering, the ability to maintain tight tolerances is what separates industrial-grade components from general fabrication. Our CNC-driven process provides digital control over every variable of the metal's transformation, from the pressure of the forming rollers to the exact path of the material displacement. We work with high-performance materials including 304/316 Stainless Steel (Density 8.00 g/cm3), Aluminum (Melting Point 660°C), and Copper (Density 8.96 g/cm3), ensuring that every part meets the geometric and dimensional requirements of your most complex blueprints.
Choosing a partner that prioritizes dimensional accuracy provides critical advantages for high-performance assembly and system integration:
For OEM clients using automated assembly lines, part consistency is vital. Our tolerance metal spinning ensures that every unit is identical, preventing jams or fitment issues in downstream robotic welding or assembly stations.
In applications involving air or fluid flow—such as fan inlets, venturis, or nozzles—even a small deviation in curvature can cause turbulence. We maintain strict profile tolerances to ensure your components perform exactly as simulated in your CFD (Computational Fluid Dynamics) models.
Precision tolerances on concentricity and wall thickness result in naturally balanced parts. For high-speed rotating components, this reduces the need for expensive post-production balancing and minimizes mechanical vibration in the final system.
When spun parts are used as housings or covers, the tolerance on the rim and flange is critical for gasket seating and sealing. We achieve the flatness and circularity required for vacuum-tight or pressure-resistant seals in medical and laboratory equipment.
We maintain tight tolerances through a combination of advanced technology and rigorous quality protocols:
A spun part is only as accurate as the mandrel it is formed over. We use CNC-machined and precision-ground steel mandrels, ensuring the internal dimensions of your part are held to within +/- 0.1 mm from the very first pass.
Our lathes use high-resolution encoders to monitor the position of the rollers. This digital feedback loop allows us to compensate for material spring-back in real-time, maintaining tight tolerances even on high-strength alloys like Stainless Steel (Boiling Point 2800°C).
To ensure the outer diameter and height are perfect, we perform CNC trimming while the part is still fixtured on the mandrel. This eliminates the errors associated with re-fixturing and ensures the edges are perfectly concentric to the center axis.
Metal expands with heat during forming. We manage the temperature of the material and the tooling during long production runs to ensure that thermal expansion does not pull the part out of its required tolerance zone.
We verify every critical dimension using calibrated CMMs, laser scanners, and ultrasonic gauges. We provide detailed inspection reports and Certificates of Conformance (CoC) to prove that every part meets your tolerance specifications.
For most medium-sized components, we routinely maintain a tolerance of +/- 0.25 mm (0.010") on diameters and +/- 0.15 mm on wall thickness, depending on the material gauge.
Yes. By combining spinning with secondary CNC machining or grinding, we can achieve tolerances as tight as +/- 0.05 mm on critical mating surfaces or bore diameters.
Ductile materials like Aluminum are easier to hold to tight tolerances. High-strength materials like Stainless Steel have more "spring-back," but our CNC programming accounts for this to ensure the final dimensions remain accurate.
Our Company HS Metal Spinning has been a dedicated OEM partner since 2014, excelling in high-precision metal forming. We serve as a technical link between architectural vision and industrial execution for firms worldwide.
