High-Speed Auto-Interlocking
Rigid interlocked core stacking performed directly inside the progressive die at 400+ SPM, eliminating manual assembly and guaranteeing uniform stack height.
HOME APPLIANCE & HVAC MOTOR SOLUTIONS
HIGH-PRECISION MOTOR CORE STAMPING FOR HOME APPLIANCES & COMPRESSORS
Engineered for quiet operation, high efficiency, and continuous 24/7 mass production. We deliver precision-stamped stator and rotor lamination stacks for air conditioner compressors, washing machines, and refrigerator pumps. Powered by our in-house manufactured tungsten carbide progressive dies and automated lamination mass production lines, we ensure ultra-low core loss and strict concentricity for global appliance OEMs.
THE APPLIANCE CHALLENGE
BALANCING ULTRA-LOW NVH NOISE & COST-EFFECTIVE MASS PRODUCTION
Modern home appliances demand silent performance and strict energy ratings. Electromagnetic vibration and core loss often stem from burrs, loose interlocking, or rotor eccentricity during stamping. Our sub-micron carbide tooling guarantees razor-thin burr clearances (<0.01mm) and high stacking factors. Combined with automated in-die interlocking, we deliver rigid, low-noise motor cores that easily pass stringent acoustic and efficiency standards.
MANUFACTURING EXCELLENCE
HIGH-SPEED STAMPING TECHNOLOGIES FOR APPLIANCE MOTORS
To support high-volume household equipment manufacturing, our automated progressive dies integrate specialized features to maximize press uptime and magnetic consistency. Explore our core assembly capabilities engineered for high-efficiency appliance stators and rotors.
MATERIAL SPECIFICATIONS
OPTIMIZED SILICON STEEL & RIGOROUS APPLIANCE STANDARDS
Selecting the right electrical steel is crucial for balancing motor efficiency and unit cost. We directly source cold-rolled non-oriented silicon steel (CRNGO) from Baosteel and WISCO, ensuring minimal core loss (W/kg) for high-EER air conditioners and refrigerator compressors. Paired with our 100% CMM inspection, every batch meets global OEM tolerances for stator and rotor laminations.

FREQUENTLY ASKED QUESTIONS ABOUT APPLIANCE MOTOR CORES
Have technical questions about lowering NVH noise, selecting silicon steel grades, or die regrinding lifespans for refrigerator and air conditioner motors? Review our FAQs below, or contact our engineers for a custom DFM analysis.
How do your stamping dies help reduce NVH noise in compressor motors?
NVH noise is mainly caused by stator slot asymmetry and burr-induced airgap distortion. Our sub-micron carbide inserts maintain <0.01mm burr clearances and exact slot symmetry, ensuring smooth magnetic flux distribution and whisper-quiet motor operation.
What is the typical regrinding interval for an appliance motor progressive die?
By utilizing premium Sandvik/Kennametal tungsten carbide inserts, our progressive dies typically achieve 3,000,000 to 5,000,000 strokes per regrind on 0.50mm electrical steel, drastically reducing press maintenance downtime.
Do you offer automatic skewed rotor stamping for home appliance motors?
Yes. Our progressive dies feature built-in rotary skewing mechanisms that automatically rotate rotor laminations by precise angles during stamping, effectively eliminating cogging torque for smooth motor starting.
Can you provide blueing or anti-rust surface treatments for exported stator stacks?
Absolutely. We provide in-house steam blueing and anti-rust oil coating for all stamped stator and rotor stacks, ensuring zero rust or corrosion during long-distance ocean shipping.
