As your trusted Original Equipment Manufacturing (OEM) partner, HS Metal Spinning delivers high-quality Spun Metal Parts specifically optimized for Anodizing. Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, and corrosion-resistant anodic oxide finish. However, a high-quality finish depends entirely on the substrate. We expertly form aluminum parts—primarily from anodizing-grade 1000, 3000, and 5000-series alloys—guaranteeing a seamless, uniform surface free of tool marks and surface defects, ensuring your finished product achieves a brilliant, consistent appearance.
Selecting spun metal parts as your substrate for anodizing provides critical aesthetic and functional benefits:
Spinning creates a jointless, monolithic part. Unlike welded assemblies where the heat-affected zone (HAZ) can result in a "ghosting" effect or color mismatch after anodizing, our spun parts provide a continuous, uniform grain structure for a flawless color match.
Anodizing hardens the aluminum surface and provides excellent weather protection. Combined with the seamless construction of spinning, this creates a component that is exceptionally resistant to environmental degradation.
Our CNC process is controlled to prevent surface "scoring" or "galling." This creates a pristine, finish-ready substrate that is ideal for clear, colored, or hard-coat anodizing, reaching the high aesthetic standards required for consumer and architectural goods.
By utilizing specific anodizing-grade alloys, our spun parts provide a consistent response to the electrolyte bath, ensuring that every part in your production run maintains repeatable color and texture.
Manufacturing high-quality Spun Metal Parts for Anodizing requires a controlled CNC workflow centered on surface preservation:
We analyze your aesthetic goal to specify the exact alloy that will provide the cleanest finish post-anodizing, ensuring the gauge is sufficient to maintain profile stability.
We use mandrels machined to an ultra-smooth finish to ensure no texture transfer to the internal surface of the spun part.
The metal is formed using multi-pass paths on rigid lathes with specialized lubricants to ensure a wrinkle-free, pristine surface that requires minimal post-form grinding.
We perform precise secondary operations, including trimming and beading, to ensure edges are smooth and do not "starve" the anodic layer during processing.
Every batch undergoes stringent visual inspection under specialized lighting to confirm the parts are defect-free and ready for the anodizing line.

We primarily recommend 5052 aluminum for its excellent strength and clear, bright response to the anodizing process. For maximum reflectivity in lighting, we suggest 1050 or 1080 high-purity aluminum.
While forming is done in-house, we coordinate the specialized anodizing finish through our certified, tier-one partners, delivering a completed, ready-to-assemble part to your doorstep.
Our CNC process is fine-tuned to ensure a smooth, uniform surface density. Any residual tooling lines are removed through our in-house pre-finishing steps (e.g., satin brushing or polishing) before the part goes to the anodizing line.
Our Company HS Metal Spinning has been a dedicated OEM partner since 2014, known for delivering high-end aesthetic metal parts for the commercial, architectural, and consumer electronics industries.
Our Commitment to Professionalism and Certifications The quality of our Finish-Ready Spun Parts is formally verified by global quality standards. We are proudly ISO 9001 certified, ensuring the batch consistency and supply-chain stability necessary for high-volume decorative anodizing projects.
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.
