Precision Engineering for Motor Core Manufacturing
HPMCN (www.hpmcn.com) is the official English website of Zhejiang Herui Precision Mould Co., Ltd.
Zhejiang Herui Precision Mould Co., Ltd. is a professional manufacturer of high-precision motor core stamping moulds based in Zhejiang, China.
Delivering world-class precision moulds for motor stator and rotor laminations, engineered with ultra-high accuracy, advanced equipment, and over a decade of industry experience.
Herui Precision is a specialist in high-accuracy stamping moulds for motor stator and rotor laminations. We design and manufacture progressive, high-speed and long-life tooling capable of producing ultra-thin electrical steel laminations down to 0.1 mm, reducing iron loss and improving motor efficiency. With advanced facilities equipped with Mazak 5-axis machining, Yasda ultra-precision milling, Sodick wire-EDM and Zeiss CMM, we ensure exceptional accuracy, stability and durability for every project. We also provide custom precision components, prototyping, and small-batch lamination production, supporting customers from R&D to mass-production mould handover.
Ultra-precision moulds
High-accuracy progressive and high-speed tooling for motor stator and rotor laminations, with ultra-thin electrical steel down to 0.1 mm to reduce iron loss.
Advanced machining equipment
Mazak 5-axis machining, Yasda ultra-precision milling, Sodick wire-EDM and Zeiss CMM secure accuracy, stability and long mould life.
From prototype to mass production
Custom components, prototyping and small-batch laminations, supporting customers from early development through to mass-production tool handover.
Precision for a Low-Carbon Future
High-efficiency motors begin with high-precision moulds.
Through advanced design and smart manufacturing, our mould solutions reduce waste, improve motor performance, and minimise carbon emissions across the full production cycle.
Optimised material utilisation
Advanced strip layout and progressive design reduce steel waste and improve yield.
Higher motor efficiency
Ultra-thin laminations with precise tolerances lower iron loss and boost motor energy performance.
Long-life tooling
Durable moulds (150–200M strokes) cut replacement frequency, transportation, and carbon footprint.
Energy-efficient manufacturing
High-efficiency Mazak, Yasda and Sodick machining centres reduce energy consumption during mould production.
