Miniature Motor Housing
We have 20 years of experience in mold-making. Our predecessor was Yuyao Jinniu Stamping Factory. This miniature motor housing is designed for "small size, high-demand" motors. Think of it as an ultra-thin bulletproof vest. It fits into precise devices such as smartphone vibration motors or medical infusion pumps.
Product Introduction
Ultra-Thin "Bulletproof Vest" for Tiny Motors
We have 20 years of experience in mold-making. Our predecessor was Yuyao Jinniu Stamping Factory. This miniature motor housing is designed for "small size, high-demand" motors. Think of it as an ultra-thin bulletproof vest. It fits into precise devices such as smartphone vibration motors or medical infusion pumps. The internal space is smaller than a fingernail, yet the precision requirements are extremely high.
The housing maintains a classic cylindrical shape and a compact structure. We also added a small rectangular anti-mistake notch on the bottom edge. This simple design is critical: on automatic assembly lines for tiny motors, the notch ensures robot arms always pick up the housing in the correct orientation. It completely eliminates assembly errors. After supplying this to a medical device client, their assembly efficiency increased by 40%, and they no longer experienced waste due to incorrect orientation.
Tolerances Tighter Than a Hair
In the world of micro motors, uniform wall thickness is essential. We continue to use ST14 high-performance deep-drawing steel for this product. Its purity and tensile properties are well recognized in the industry.
With this material, we can form walls as thin as 0.15 mm - barely thicker than a human hair - without cracking or wrinkling. The wall still maintains excellent strength and toughness. Thickness is fully customizable for your micro motor design.
Most importantly, we control dimensional tolerances within ±0.02 mm - thinner than a hair. How do we achieve this precision? Through our 200–500 ton high-precision presses and 20 years of mold-making experience. The product's CPK value consistently remains above 1.33, meeting ISO 2768-f (fine) standards. This ensures that every miniature housing we produce is highly precise and ready for assembly without issues.

Efficient Heat Dissipation
Micro motors have high power density, making heat dissipation a major challenge. This miniature motor housing is made of metal, which conducts heat effectively.
We can also add micro ventilation holes or cooling textures on the surface, designed using microfluidic simulations. These features accelerate heat transfer from the small area. Tests show that this housing can reduce motor temperature rise by 15–20%, lowering the risk of magnet demagnetization.
We can apply electroless nickel plating or eco-friendly nano-coatings, which comply with RoHS 2.0 and REACH regulations for excellent corrosion protection. If your micro motor needs to perform reliably in a compact space, choose our miniature motor housing.
