Large Diameter Spun Parts Supplier Overview


As your specialized Original Equipment Manufacturing (OEM) partner, HS Metal Spinning is the premier Large Diameter Spun Parts Supplier for massive engineering and architectural projects. Manufacturing seamless components measuring several meters in diameter—such as massive storage tank heads, heavy-duty industrial cones, and iconic architectural domes—requires extreme power and high-precision control. We expertly form these oversized components from Carbon Steel, Stainless Steel, and Aluminum, guaranteeing perfect rotational symmetry, monolithic structural strength, and uniform wall thickness across every millimeter of the component’s radius.


Advantages of Our Large Diameter Spun Parts Supplier Products


Partnering with an expert large diameter spun parts supplier provides critical benefits for heavy-duty and large-scale infrastructure:

Seamless Monolithic Integrity

For oversized components, spinning creates a jointless structure, eliminating the hundreds of meters of welding required in segmented fabrication. This superior structural form is essential for pressure integrity and aesthetic purity.


Predictable Geometric Consistency

Our high-tonnage CNC lathes ensure that even at extreme scales, the component adheres to the blueprint's radius and curvature. This perfect concentricity simplifies on-site assembly and minimizes installation downtime.


Optimized Weight Distribution

Spinning guarantees uniform material consolidation across the large surface area, resulting in predictable balance and mass, which is vital for large-scale ventilation rotors, tank assemblies, and suspended architectural features.


Tooling Cost Efficiency

Unlike stamping, which requires multi-million dollar die sets for massive parts, our spinning mandrels are cost-effective to produce, making custom large-diameter projects financially feasible for both prototypes and batch production.


Our Large Diameter Spun Parts Supplier Technological Process


Operating as a premier Large Diameter Spun Parts Supplier requires massive industrial force paired with technical finesse:

1. Industrial DFM & Radius Verification

We analyze the blank diameter and material gauge to calculate the necessary hydraulic forming force, ensuring the structural stability of the mandrel and material throughout the draw.


2. Heavy-Duty CNC Lathe Selection

Components are formed on our highest-capacity rigid lathes, which are designed to deliver the immense forming pressure required for large-format ferrous and non-ferrous metals.


3. Controlled High-Force Spinning

The metal blank is formed using multi-pass, high-tonnage tool paths, ensuring the metal consolidates uniformly without fractures, guaranteeing perfect rotational symmetry and repeatable wall thickness.


4. Integrated Heavy-Duty Trimming

We perform precise in-house secondary operations on oversized parts, including edge trimming, punching large bolt patterns, and integrating structural reinforcing rings.


5. Large-Scale Metrology & Geometric Inspection

Every part undergoes visual and laser metrology verification to confirm that critical mounting diameters and geometric curvatures adhere to specified sub-millimeter tolerances across the entire span.

FAQs about Large Diameter Spun Parts Supplier


What is the maximum diameter you can reliably spin?

Our high-capacity lathes allow us to produce components exceeding several meters in diameter. Exact feasibility depends on material thickness and component depth.


How do you protect oversized parts from deformation during transport?

Our service includes custom protective crating and internal structural bracing designed specifically for your dome or cone’s geometry, ensuring zero "oil-canning" or distortion during international transit.


Can you spin large-diameter parts from heavy-gauge stainless steel?

Yes. We are experts in forming Heavy-Gauge Stainless Steel (304/316) at large scales, maintaining corrosion resistance and structural integrity across massive industrial surfaces.
