Thin Wall Metal Spinning

We are experts in Thin Wall Metal Spinning, a precision technique for forming high-fidelity components from thin metal sheets. As an ISO 9001 certified OEM partner, HS Metal Spinning utilizes advanced CNC technology to maintain structural integrity and sub-millimeter tolerances in materials like Aluminum and Stainless Steel. Our process is ideal for lightweight enclosures, reflectors, and sensitive sensor housings, providing significant material savings and superior surface finishes while preventing wrinkles or material failure during the cold-working process.

Thin Wall Metal Spinning Overview


As your strategic Original Equipment Manufacturing (OEM) partner, HS Metal Spinning offers specialized Thin Wall Metal Spinning. Forming thin-gauge materials requires exceptional control to prevent wrinkling, tearing, or uneven thinning. Our CNC spinning process excels at producing lightweight, rotationally symmetrical components—such as decorative lighting reflectors, medical sensor shields, and aerospace heat shrouds—from sheets as thin as 0.5mm. We expertly form materials including Aluminum, Stainless Steel, and Copper, ensuring that even the most delicate components maintain their structural integrity and precise geometric profiles.


Advantages of Our Thin Wall Metal Spinning Products

Choosing thin-wall spinning for your precision components offers significant performance and cost benefits:

Maximum Weight Reduction

For industries like aerospace and portable medical devices, every gram counts. Our process allows us to create monolithic, seamless enclosures using the minimum material thickness required for structural stability, resulting in high-performance, lightweight components without the need for heavy casting or multi-part assemblies.


Exceptional Wall Thickness Uniformity

In thin-gauge forming, maintaining consistency is critical. Our multi-axis CNC lathes provide digital control over the roller path and pressure, ensuring uniform wall thickness across the entire part. This prevents the "weak spots" typically found in manual spinning or deep-drawn thin parts.


Superior Material Efficiency

Thin wall spinning is a near-net-shape process that maximizes the use of raw material blanks. By precisely displacing the metal rather than machining it away, we offer a cost-effective solution that reduces scrap and raw material costs, especially when working with expensive alloys like Stainless Steel or Copper.


High-Quality Surface Finishes

Thin-gauge parts often require high-end finishes for optics or aesthetics. The smooth, seamless surface produced by our CNC cold-working process serves as an ideal substrate for bright anodizing, polishing, or PVD coating, ensuring the final part meets both functional and visual standards.


Our Thin Wall Metal Spinning Technological Process


Manufacturing delicate, thin-wall components requires a specialized workflow focused on material stability:

1. Thin-Gauge DFM Analysis

Our engineers evaluate the material's ductility and the component's geometry to determine the optimal starting gauge. We optimize the spin path to prevent excessive thinning and ensure the material stays within its elastic limits.


2. Precision-Polished Mandrel Setup

For thin walls, any imperfection on the tooling will transfer to the part. We use precision-machined, high-polish mandrels to ensure the internal surface of the spun component is flawless and accurate to 0.1 mm.


3. Sensitive CNC Multi-Pass Forming

The metal is formed using multiple light passes. This incremental approach prevents the build-up of stress that causes tearing in thin sheets, allowing us to achieve deep profiles while maintaining the integrity of the material.


4. Controlled Edge Trimming and Beading

Thin edges can be sharp and fragile. We integrate CNC trimming and edge beading (curling) into the cycle to provide structural rigidity and safety to the finished component without adding significant weight.


5. Metrology and Wall Thickness Verification

Every thin-wall part is inspected using ultra-precise ultrasonic thickness gauges and CMMs to verify that the wall thickness and overall dimensions meet the strict tolerances required for the application.

FAQs about Thin Wall Metal Spinning


What is the minimum wall thickness you can achieve?

Depending on the material and part diameter, we routinely spin form components with wall thicknesses as low as 0.5 mm in aluminum and 0.8mm in stainless steel.


How do you prevent the material from wrinkling?

Wrinkling is prevented through precise CNC control of the "feed-to-speed" ratio and the use of specialized backer tools or support rollers that stabilize the thin material during the forming passes.


Is thin wall spinning suitable for pressure applications?

Yes, provided the engineering design accounts for the pressure requirements. Because spinning cold-works the material, it increases the yield strength, making thin-wall spun parts surprisingly resilient for their weight.
