As your specialized Original Equipment Manufacturer (OEM), HS Metal Spinning supplies high-precision Spun End Caps critical for securely sealing pipes, protecting structural members, and finishing vessel assemblies. End caps must be dimensionally accurate to ensure perfect fit-up and robust enough to handle pressure, weather, or physical impact. We expertly form seamless end caps from a wide range of materials, including carbon steel, stainless steel, and aluminum, guaranteeing uniform wall thickness, perfect concentricity, and a reliable, single-piece structure superior to welded alternatives.
Choosing seamless spun end caps offers key technical and structural benefits for reliable sealing and protection:
End caps spun from a single blank are inherently stronger and eliminate the risk of leaks associated with welded seams, making them ideal for sealing pipe ends or small pressure vessels.
Used on the end of structural tubing or piling, the seamless, symmetrical cap provides excellent resistance to impact and weather, prolonging the life of the enclosed structure.
Our precision CNC spinning ensures that the cap's diameter and depth meet extremely tight tolerances, guaranteeing a flawless, immediate fit for welding or structural retention.
For high-volume projects requiring symmetrical, durable end caps in various sizes, spinning offers the most cost-effective and scalable manufacturing solution, significantly reducing the tooling costs of stamping.
Manufacturing high-integrity Spun End Caps requires a controlled, high-force CNC workflow:
We confirm the required material grade and review the dimensions against standard piping sizes (e.g., NPS, OD).
Custom mandrels are precisely fabricated to match the required curvature. CNC programs are written to execute a controlled tool path, guaranteeing uniform thickness and perfect symmetry.
The metal blank is formed on our rigid, high-precision CNC lathes. This ensures perfect rotational symmetry and repeatable, sub-millimeter dimensional accuracy across all production runs.
Components are processed through in-house secondary operations, including precision trimming of the straight flange to the exact required length and applying the necessary weld prep.
Every end cap undergoes stringent dimensional inspection to verify its outside diameter (OD), depth, and flange length, ensuring consistent quality for mass production.
Yes. We manufacture our end caps to precisely match the outer diameter (OD) of standard piping and tubing sizes (e.g., Schedule 40, Schedule 80), ensuring a perfect fit for welding or retention.
Spun end caps generally offer better consistency in wall thickness and are more cost-effective for custom, smaller-to-medium-sized diameters and lower volumes compared to the high tooling costs of stamping.
Yes. Our service includes applying the required bevel or other weld preparation to the straight flange of the end cap, ensuring it is ready for immediate, code-compliant welding to the pipe or vessel.
At HS Metal Spinning, we focus on providing specialized Original Equipment Manufacturing (OEM) solutions for Spun End Caps. We partner with manufacturers in piping, fabrication, and structural engineering to deliver components optimized for their intended end-use.
Our comprehensive service includes: Material Optimization: Advising on the best metal—from lightweight aluminum for aesthetic covers to heavy-gauge carbon steel for structural protection. Design-for-Manufacture (DFM): Optimizing the cap's depth, curvature, and flange for perfect compatibility with standard pipe schedules and tube sizes. Integrated Fabrication: Providing value-added services such as trimming the flange to a precise length and applying the necessary weld preparation (beveling) for immediate, high-quality fabrication integration.
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.
