About Shenzhen Jiarun Precision Industry Co., Ltd - Electric Motors Supplier in China

China, and more precisely Shenzhen, currently offers five active product listings from Shenzhen Jiarun Precision Industry Co., Ltd. The catalogue includes high‑speed motor stator and rotor assemblies, motor stator and rotor laminations, brush‑less motor stator laminations, a metal punching mould, and a motor‑core progressive die. Each entry falls under the broader HS‑code families for electric motor components (typically 8501) and metal‑working tools (often 8462). The supplier is classified as an imported, harbor‑tier entity in the platform’s trust system.

The listed items are positioned within the “Electric Motors” and “Electric Machines & Equipments” categories. The motor stator and rotor products are core parts for AC and DC motor assemblies, while the brush‑less stator lamination targets high‑efficiency, low‑maintenance drives. The metal punching mould and progressive die support the manufacturing of these cores, enabling batch production of thin‑laminated stacks. No additional product lines beyond the five entries are indicated in the supplied data.

Product Range and Specialties of Shenzhen Jiarun Precision Industry Co., Ltd

The catalogue focuses on motor core components: high‑speed stator‑rotor sets, separate stator and rotor laminations, and brush‑less motor stator laminations. In the electric motor industry, stator laminations are commonly made from silicon‑steel sheets meeting EN 10346 grade 1 or grade 2 specifications, with thicknesses ranging from 0.2 mm to 0.5 mm and magnetic permeability above 5000 A/m. Brush‑less designs often require tighter dimensional tolerances (±0.02 mm) and surface roughness below 0.8 µm to reduce eddy‑current losses. The metal punching mould and progressive die are typical tooling used to stamp these laminations, usually fabricated from high‑carbon tool steel (e.g., D2) or carbide inserts to achieve long tool life at production rates of 5‑10 km of lamination per hour.

Trade and Export Information - Shenzhen Jiarun Precision Industry Co., Ltd

China remains a leading exporter of electric motor components, with the majority of shipments destined for Southeast Asia, Europe, and North America. HS‑code 8501 covers complete electric motors, while sub‑headings 8501.31‑33 often apply to stator‑rotor assemblies; tooling such as punching moulds and progressive dies falls under HS‑code 8462 for machine tools. Buyers typically request ISO 9001 quality‑management certification, CE marking for EU markets, and RoHS compliance for electronic applications. Standard export logistics involve containerised loads (20‑ft or 40‑ft) with wood pallets, and Incoterms such as FOB Shenzhen or CIF destination port are common. Chinese export regulations require a commercial invoice, packing list, and, for motor parts, a declaration of compliance with the relevant electromagnetic‑compatibility (EMC) standards.

Sourcing from Shenzhen Jiarun Precision Industry Co., Ltd - Buyer Guidance

When sourcing from Shenzhen Jiarun, request material certificates confirming silicon‑steel grade, thickness, and magnetic properties for the laminations. Ask for a sample of the punched lamination to verify dimensional accuracy and surface finish before committing to full production. Verify that the supplier can provide ISO 9001 or equivalent quality‑system documentation, and confirm whether CE or RoHS declarations are available for the motor core products. Typical minimum order quantities range from 5 km to 20 km of lamination per order, with lead times of 4‑6 weeks for tooling‑included items and 2‑3 weeks for standard laminations. Packaging is usually in wooden crates with moisture‑absorbing liners to protect thin steel sheets during ocean freight.

What types of motor core components does Shenzhen Jiarun list?

The supplier lists high‑speed motor stator‑rotor assemblies, separate stator and rotor laminations, brush‑less motor stator laminations, a metal punching mould, and a motor‑core progressive die.

Which HS codes are relevant to these products?

Motor stator‑rotor assemblies generally fall under HS 8501, while the punching mould and progressive die are classified under HS 8462 for machine tools.

What material grades are typical for the stator laminations?

Industry practice uses silicon‑steel sheets meeting EN 10346 grade 1 or grade 2, with thicknesses between 0.2 mm and 0.5 mm and magnetic permeability above 5000 A/m.

What certifications should a buyer request?

Buyers should request ISO 9001 quality‑system certificates, CE marking for EU markets, and RoHS compliance statements for electronic applications.

What are common minimum order quantities and lead times?

MOQ is typically 5 km to 20 km of lamination per order; lead time is about 4‑6 weeks for orders that include tooling and 2‑3 weeks for standard laminations.

How are the products usually packaged for export?

Products are packed in wooden crates with moisture‑absorbing liners, secured on pallets to prevent deformation of thin steel sheets during sea transport.

What documentation is needed for customs clearance?

A commercial invoice, packing list, material certificates, and any applicable CE or RoHS conformity declarations are normally required.

Which regions most commonly import these motor core components?

Major import destinations include Southeast Asian countries, the European Union, and North America, where they are used in industrial drives, HVAC systems, and electric vehicle powertrains.
