Advanced Surface Finishing Solutions for Steel Motor Housings
Optimized Steel Materials for Precision Motor Stamping
Galvanized and cold-rolled steel are the most cost-effective and reliable choices for micro motor components, offering excellent formability, magnetic shielding, and structural rigidity. At Yongyuan, we optimize your material selection. By choosing the precise grade—from highly formable SPCE for deep-drawn motor cans to corrosion-resistant SECC for precision end covers—we ensure your housings meet the exact mechanical demands of your application. Every batch is strictly verified for zinc-coating thickness and consistency under our IATF 16949 quality system.

SPCC
SPCC is a widely used commercial cold-rolled steel for general stamping parts, cover plates, brackets, and shallow-drawn housings. It offers stable formability, smooth surface quality, and cost-effective performance for high-volume motor hardware applications.

SPCD
SPCD is a drawing quality cold-rolled steel designed for parts that require better ductility than standard commercial grades. It is suitable for stamped and moderately drawn motor housings, end covers, and structural components that need stable forming performance.

SPCE
SPCE is a deep drawing quality cold-rolled steel developed for parts with higher forming demands. It is ideal for deep-drawn motor housings, cylindrical shells, and precision cover components that require excellent ductility and stable shaping performance.

SECC
SECC is an electro-galvanized steel with a smooth surface, good corrosion resistance, and reliable stamping performance. It is widely used for precision metal housings, cover plates, terminals, and electronic hardware parts that require both formability and a clean appearance.

Drawing Quality Electro-Galvanized Steel
Drawing Quality Electro-Galvanized Steel combines the smooth surface and corrosion resistance of electro-galvanizing with improved formability for stamped and drawn parts. It is well suited for precision motor casings, end covers, terminals, and metal housings that require both appearance quality and reliable shaping performance.

Deep Drawing Hot-Dip Galvanized Steel
Deep Drawing Hot-Dip Galvanized Steel is designed for stamped parts that require enhanced corrosion resistance and deeper forming capability. It is suitable for motor housings, protective covers, and metal shells that need stable deep drawing performance in demanding industrial applications.

Anti-Fingerprint Galvanized Steel
Anti-Fingerprint Galvanized Steel features a protective surface treatment that helps reduce visible fingerprints, light stains, and handling marks. It is suitable for stamped cover plates, visible housings, and precision metal parts that require both corrosion resistance and a cleaner surface appearance.

Zinc-Aluminum-Magnesium Coated Steel
Zinc-Aluminum-Magnesium Coated Steel offers enhanced corrosion resistance compared with conventional galvanized steel, especially for edges and challenging service environments. It is suitable for stamped housings, cover plates, structural parts, and metal shells that require long-term durability and reliable forming performance.
What is galvanized steel stamping?
Galvanized steel stamping (using SECC, SGCC, or SPCC) is a highly cost-effective process for mass-producing motor components. At Yongyuan, we use high-tonnage presses and Deep Drawing techniques to manufacture precision motor housings and shields with tight ±0.01mm tolerances.
Advantages of galvanized steel stamping
Cost-Effective: Significantly more affordable than stainless steel, making it the industry standard for high-volume micro motors.
Built-In Rust Resistance: The uniform zinc layer (SECC/SGCC) acts as a sacrificial shield against corrosion.
Magnetic Shielding: Natural steel permeability prevents electromagnetic interference (EMI) in precision motors.
High Rigidity: Delivers exceptional structural durability for heavy-duty automotive brackets and industrial applications.
Disadvantages of galvanized steel stamping (And Our Solutions)
Zinc Layer Flaking: Deep drawing can cause zinc to peel. Our Solution: We use advanced die clearance controls and extreme-pressure lubricants to ensure the zinc stretches flawlessly.
Edge Rust on Sheared Cuts: Stamping exposes bare iron edges. Our Solution: We apply integrated secondary treatments like e-coating (black finish) or plating to seal all cuts perfectly.
Tool Wear: Hard steel accelerates die wear. Our Solution: We build heavy-duty progressive dies using premium tungsten carbide, ensuring precision for up to 10 million strokes.
