Contract Metal Spinning Overview


As your strategic Original Equipment Manufacturing (OEM) partner, HS Metal Spinning provides professional contract metal spinning services designed for long-term industrial collaboration. Contract manufacturing requires a partner who can guarantee consistent quality, adhere to strict production schedules, and offer technical expertise in material forming. Our facility utilizes advanced CNC spinning technology to transform metal blanks into high-performance components such as pressure vessel ends, filtration housings, and turbine components. We expertly process industrial-grade materials including 304/316 Stainless Steel (Density 8.00 g/cm3), 1050/6061 Aluminum (Melting Point 660°C), and Carbon Steel (Density 7.85 g/cm3), ensuring every part meets your exact engineering blueprints.


Advantages of Our Contract Metal Spinning Products

Partnering with HS Metal Spinning for your contract manufacturing needs provides several key advantages that optimize your supply chain:

Reduced Capital Expenditure

By utilizing our contract metal spinning services, you gain access to high-tonnage CNC machinery and specialized tooling without the significant capital investment of in-house production. This allows you to allocate your resources toward core product development while we handle the complexities of precision metal forming.


High Repeatability and Precision

Our CNC-controlled process eliminates the variances typical of manual spinning. Every part in a contract run is formed using the same digital program, ensuring that tolerances—often as tight as +/- 0.2 mm—are maintained from the first piece to the last. This consistency is vital for components that must integrate into high-precision assemblies.


Material Traceability and Quality Assurance

We maintain a robust quality management system certified to ISO 9001 standards. Every contract project includes full material traceability, providing Material Test Reports (MTRs) and Certificates of Conformance (CoC). We utilize advanced metrology, including CMM and ultrasonic gauges, to verify that every component meets the required mechanical and dimensional specifications.


Scalable Production Capacity

We offer the flexibility to manage your entire product lifecycle. Our infrastructure can handle small-batch pilot runs as well as high-volume annual contracts, allowing us to scale our production output to match your fluctuating market demands without compromising on lead times.


Our Contract Metal Spinning Technological Process


Our workflow is designed to ensure a seamless "drawing-to-part" experience for our contract partners:

1. Engineering Review and DFM

We perform a comprehensive review of your technical drawings to ensure optimal manufacturability. We offer Design for Manufacturing (DFM) feedback to help reduce material waste and simplify the forming process, lowering your overall part cost.


2. Custom Tooling and Mandrel Fabrication

We design and manufacture all necessary spinning mandrels in-house. For long-term contract work, we utilize hardened tool steels to ensure the mandrel maintains its dimensional integrity over thousands of cycles.


3. Precision CNC Forming

Your parts are produced on our multi-axis CNC lathes. We monitor material displacement and hydraulic pressure in real-time, ensuring uniform wall thickness and a smooth surface finish that is ready for secondary treatments.


4. Secondary Operations and Finishing

Beyond spinning, we offer integrated secondary services including CNC trimming, hole punching, beading, and certified TIG/MIG welding. We can also coordinate with local partners for specialized finishes such as anodizing or powder coating.


5. Inspection and Global Logistics

Every batch undergoes a final quality audit before being packed in custom crates. We manage the logistics to ensure your components arrive at your facility—whether local or international—ready for immediate assembly.
