Steel/Stainless/Heavy-Wall Steel/Steel Tube Motor Housing Manufacturers

Motor Housing Manufacturer: Steel, Stainless, Heavy-Wall & Tube Housings

Jiangsu Yufeng Electric Co., Ltd. is a professional motor housing manufacturer and supplier in China, specializing in the R&D and production of steel, stainless steel, heavy-wall steel, and steel tube motor housings. With 40 years of industry focus, we integrate stamping, welding assembly, machining, and surface treatment into one full-process production system. Our products serve household appliances, industrial drives, new energy vehicles, and special equipment, delivering high-precision and high-reliability solutions for OEMs and project-based requirements.

Our factory in Jingjiang City, Jiangsu Province, operates with advanced stamping lines, automated welding equipment, machining centers, and inspection instruments. We support customers from drawing review to mass production, with an engineering team averaging over 20 years of experience. Whether you need a standard housing or a fully customized design, we provide the technical depth and production capacity to meet your specifications.

Our Product Range

We manufacture a broad range of motor housings, each tailored to specific application demands. Below is an overview of our product categories and their typical uses:

Application Fit and Material Selection

Choosing the right housing material and design is critical for motor performance and longevity. Our steel housings are ideal for cost-sensitive, high-volume applications where strength and formability are balanced. Stainless steel housings are specified when corrosion resistance or hygiene is paramount, such as in food and beverage or pharmaceutical environments. Heavy-wall steel housings provide extra rigidity for larger motors that experience high torque or vibration. Steel tube housings offer a lightweight yet durable option for cylindrical motor designs.

We work with your engineering team to select the appropriate material grade, wall thickness, and surface treatment—whether it's e-coating, powder coating, or bare metal—to match your operating environment and performance requirements.

Critical Specifications and Customization

Our motor housings are manufactured to precise tolerances, with inner diameters ranging from 29.6 mm to 343 mm and beyond. Key specifications we control include:

• Inner diameter tolerance: typically ±0.05 mm, depending on application
• Concentricity and roundness for smooth rotor operation
• Mounting bracket configurations: flexible, base, T-base, or custom
• Surface finish options: smooth, textured, or coated for corrosion protection
• Material grades: SPCC, SECC, 304SS, or custom alloys

We accept non-standard customization, including housing structure optimization, mounting dimension adaptation, and surface treatment selection. Our in-house tooling design and process optimization allow us to respond quickly to your unique requirements.

Production Capacity and Quality Assurance

With an annual production capacity exceeding 5 million units, we handle both large-volume orders and small-batch production runs. Our quality management system is ISO 9001:2015 certified, and we implement process control and traceability in line with IATF 16949 standards for automotive and new energy vehicle applications.

Quality is embedded at every stage: incoming material inspection, in-process checks with custom gauges, and final inspection before packaging. Each batch is traceable to raw material lots, production machines, and operators, ensuring full accountability and rapid corrective action if needed.

Integration and Support

We support your project from initial concept to series production. Our engineering team assists with design for manufacturability, prototype development, and testing. For automation integration, we ensure housings are compatible with your assembly lines, providing consistent dimensions and mounting features. We also offer packaging and delivery options that protect parts during transit and align with your inventory management.

Information We Use to Configure Your Solution

To prepare an accurate quotation and configuration, please provide the following details:

• Product drawings or detailed specifications (dimensions, materials, tolerances)
• Estimated annual demand or quantity per batch
• Surface treatment requirements (e-coating, powder coating, etc.)
• Special technical requirements (IP rating, precision class, etc.)
• Any applicable industry standards or certifications

With this information, we typically provide a quotation within 2–3 working days and deliver standard custom samples within 3–10 working days.
