High-Speed Stamping for Stator Cores Manufacturing

High-speed stamping delivers precise, consistent stator laminations with tight dimensional control, low burrs, and efficient production for demanding motor applications.

High-speed stamping is a continuous manufacturing process that uses high-speed presses and precision dies to produce motor laminations rapidly and consistently from electrical steel. It enables accurate dimensions, controlled burr height, high production efficiency, and stable quality for large-volume stator core manufacturing.

Frequently Asked Questions

What is high-speed stamping?

High-speed stamping is a continuous manufacturing process that uses high-speed presses and precision progressive dies to produce motor laminations rapidly and consistently from electrical steel coils. It enables high production efficiency, accurate dimensions, controlled burr height, and stable quality.

What materials do you stamp?

We primarily stamp non-oriented electrical steel (NGO) in various grades and thicknesses for stator and rotor laminations. Material selection is based on the motor design, core loss, efficiency, operating speed, and magnetic performance requirements.

What thicknesses are available?

We can process various electrical steel thicknesses, with the specific gauge selected according to motor design, core loss, efficiency, operating frequency, and magnetic performance requirements. Common lamination thicknesses include approximately 0.20–0.65 mm, subject to material grade and production requirements.

Can you manufacture according to drawings?

Yes. We manufacture precision stator and rotor laminations according to customer drawings, 2D/3D CAD files, material specifications, dimensional tolerances, and production requirements. We also support prototype development, trial stamping, inspection, and volume production.

What tolerance can you achieve?

We can achieve tight dimensional tolerances for critical lamination features, with the actual tolerance determined by the material thickness, part geometry, tooling design, and production requirements. Key dimensions are controlled according to customer drawings and agreed technical specifications.

Do you support prototype production?

Yes. We support prototype and small-batch production for new stator and rotor lamination designs. Trial parts can be produced for dimensional verification, burr inspection, assembly testing, and motor performance evaluation before mass production.

What industries do you serve?

We serve a wide range of motor and power-generation industries, including electric vehicles, eMobility, BLDC motors, servo motors, industrial motors, generators, automation, robotics, pumps, compressors, and HVAC systems.
