When your application demands uncompromising corrosion resistance, high strength, and aesthetic cleanliness, choose Stainless Steel Spun Parts from HS Metal Spinning. We are experts in forming precision, seamless components—such as vessels, cones, domes, and reflectors—from various stainless steel grades (304, 316, etc.). Our advanced CNC spinning process guarantees uniform wall thickness, perfect rotational symmetry, and a flawless surface finish, making us the preferred OEM partner for sanitary, architectural, marine, and industrial applications globally.
Leveraging the unique properties of stainless steel with the precision of CNC spinning offers significant advantages over alternative manufacturing methods.
Stainless steel's passive chromium oxide layer provides superior resistance to rust, chemicals, and harsh atmospheric conditions, ensuring extended component lifespan in demanding environments.
Spinning produces a monolithic, seamless part, eliminating the stress risers and heat-affected zones inherent in welding. The process also increases material hardness, resulting in a stronger, more durable final product.
The smooth, non-porous surface of Stainless Steel Spun Parts is easily maintained and sanitized, making it ideal for the food, beverage, and pharmaceutical industries. Aesthetically, the seamless finish is highly desirable for architectural and decorative features.
For deep, symmetrical shapes, spinning offers low tooling costs and faster lead times compared to CNC machining from solid stock or complex deep drawing.
Manufacturing high-strength, precise stainless steel components follows a rigorous, quality-focused workflow:
We specify the exact stainless steel grade (e.g., 304 or 316) based on your application and perform a Design-for-Manufacture (DFM) review to optimize spin-formability and minimize material use.
Robust, high-strength tool steel mandrels are used. CNC programs apply carefully controlled, high forming forces necessary to precisely shape the stainless steel while maintaining tight dimensional tolerances.
The stainless steel blank is formed on our advanced, rigid CNC lathes. This ensures uniform wall thickness and a high degree of concentricity across all Stainless Steel Spun Parts.
We perform in-house secondary operations, including precision laser cutting and punching of complex hole patterns. The parts are prepared for external processes such as welding, heat treating, or passivation.
Every component undergoes stringent dimensional inspection using advanced metrology. We can perform Positive Material Identification (PMI) testing upon request to verify the correct alloy was used, a crucial step for certified applications.

Yes. While the spinning is done in-house, we manage all required external finishing, including passivation (essential for chemical resistance) and electropolishing (for a mirror, sanitary finish), through our network of certified partners.
Spinning is often more economical for symmetrical, deep components with smaller batches due to lower custom tooling costs. It also often produces a component with more uniform wall thickness in the direction of the metal flow.
Absolutely. We only source certified material, and we can provide material certifications and perform in-house PMI (Positive Material Identification) testing upon request to verify the exact alloy is correct.
At HS Metal Spinning, we focus on providing specialized Original Equipment Manufacturing (OEM) solutions for Stainless Steel Spun Parts. We function as a dedicated technical partner, helping you select the appropriate stainless steel grade and optimizing your design for the spinning process.
Our service extends beyond forming to include all necessary value-added operations, such as precision trimming, flanging, and the essential surface preparation required before post-treatments like passivation (to maximize corrosion resistance) and electropolishing (for a mirror finish).
Spanning over 10,000 m² (over 107,000 sq ft), is designed specifically for large-scale, high-volume OEM production. This robust infrastructure ensures that HS Metal Spinning can deliver rapid turnaround and scalable manufacturing for projects ranging from low-volume prototypes to high-volume production runs, guaranteeing your supply chain remains uninterrupted. Our clean, well-lit, and highly organized environment is a testament to our commitment to a professional manufacturing process. Every piece of equipment is meticulously maintained and regularly calibrated to ensure the highest level of precision.

Our facility is equipped with a comprehensive suite of advanced machinery that represents a significant investment in technology and efficiency. These machines allow us to take on complex projects with confidence and precision. The equipment includes:
The core of our operations, these machines are at the forefront of metal forming technology. With a variety of different models and sizes, our machines can handle a wide range of part diameters and thicknesses. This versatility allows us to produce everything from small, intricate components for electronics to large-scale parts for aerospace and industrial applications. Our machines are capable of executing complex forming sequences with repeatable accuracy, minimizing human error and maximizing efficiency.
These machines provide us with integrated fabrication solutions. We can swiftly and precisely create multiple holes, slots, or other shapes in your spun parts, eliminating the need for a separate, time-consuming process. This capability is vital for components that require specific mounting points or ventilation features.
This further enhances our in-house capabilities, enabling us to perform precise cuts and create intricate patterns on pre-spun components. The laser cutter provides exceptional accuracy and clean edges, which is crucial for high-quality finished products. HS Metal Spinning also has a full range of essential CNC machines, ensuring we are a turnkey manufacturing solution for all your OEM needs.
