AUTO-INTERLOCKING SYSTEM

In-die automatic stacking technology for stators and rotors, eliminating the need for secondary welding or riveting processes.

ROTARY SKEWING

Stepless skewing control to significantly reduce motor cogging torque.

MODULAR SPARE PARTS

Quick-change insert design minimizes production downtime.
PROVEN RESULTS

FLAWLESS STATOR & ROTOR LAMINATIONS

The ultimate proof of a premium progressive die is the lamination it produces. Explore our gallery of burr-free, perfectly interlocked silicon steel cores. From micro UAV motors to large EV traction motors, we ensure absolute consistency in every stroke.
STAMPING PROCESS

PRECISION MULTI-STATION STRIP LAYOUT

Our high-speed progressive dies integrate complex operations into a single continuous stamping process. From precision piercing to in-die interlocking, every station is engineered for maximum stability at high SPM (Strokes Per Minute).

Pilot Piercing & Shaft Hole Stamping

High-precision tungsten carbide punches create exact reference points and rotor shaft holes with minimal burr, setting the baseline for sub-micron accuracy.

Auto-Interlocking & Stacking

Engineered with precise interlocking nibs that press individual laminations together automatically inside the die, forming a solid stator-rotor core stack.

TECHNICAL FAQ

EXPERT ANSWERS TO YOUR TOOLING QUERIES

Have specific technical requirements for your motor core project? Review our technical FAQs below, or contact our engineering team directly for a custom DFM consultation.

We primarily utilize premium imported tungsten carbide grades (such as Sandvik or Kennametal equivalents) with fine grain structures, offering superior wear resistance and impact toughness specifically tuned for high-speed silicon steel stamping.

Our precision machining permits cutting clearances tight enough to stamp ultra-thin electrical steel laminations down to 0.2mm without burr, ideal for high-efficiency EV and servo motors.

Our progressive dies integrate automated rotary skewing/indexing systems. By rotating stator or rotor laminations by a specified angle during stacking, coil thickness variations are evenly distributed, eliminating lamination stack tilting.

Standard lead time ranges from 4 to 6 weeks after DFM and CAD drawing approval, including 100% in-house machining, assembly, and high-speed stamping trials.
