Shanghai Husu M&E Technology Co., Ltd

OEM/ODM – Tailored to Your Specifications

We understand that different applications require different wire characteristics. That’s why we offer flexible OEM and ODM services for regular enameled wires.

Customizable parameters include:

1, Conductor material (copper, aluminum, CCA)

2, Thermal class (130L to 240)

3, Insulation type (polyester, polyurethane, polyesterimide, polyamide-imide, polyimide)

4, Film grade (1, 2, or 3)

5, Conductor diameter and tolerance

6, Spool types and packaging specifications

We work with customer-supplied technical drawings or standards (IEC, GB, NEMA, JIS). Our team provides fast prototyping, sample approval, and seamless scale-up to mass production.

Your specification. Our production. No guesswork.

Production Line – Precision in Every Coating

Our factories are located in Jiangsu and Zhejiang, equipped with automated enamelling lines that support continuous production of copper, aluminum, and copper-clad aluminum round wires.

Each production line integrates:

Multi-pass annealing and painting for consistent film adhesion

Real-time diameter monitoring with automatic adjustment

In-line spark testing to ensure insulation integrity

We produce thermal classes from 130L to 240, with film grades 1, 2, and 3, across conductor diameters from 0.02mm to 4.00mm. Our monthly capacity for regular enameled wires reaches 100 tons, enabling stable supply for both sample and bulk orders.

Every coil is traceable – from raw copper to finished wire.

Quality Certifications

Our factories operate under ISO 9001 quality management systems. All regular enameled wires meet RoHS environmental requirements and comply with IEC 60317, GB/T 6109, NEMA MW 1000, and JIS C 3202 standards.

Third-party testing reports are available upon request.

R&D – Continuous Improvement in Wire Performance

Our factories have invested over a decade in enameled wire manufacturing, with some facilities accumulating more than 20 years of R&D experience. We focus on practical innovation that improves product consistency, thermal performance, and production efficiency.

Our R&D capabilities include:

1, Formulation and application of insulation coatings

2, Optimization of annealing and baking profiles

3, Analysis of film thickness uniformity and pinhole distribution

4, Long-term thermal aging and cut-through temperature testing

We hold multiple patents related to enameled wire manufacturing. Our technical team works closely with production to ensure that every improvement translates into measurable quality gains for our customers.

Small improvements, batch after batch.

The Team Behind the Wire

Behind every coil of enameled wire stands a team that values precision, consistency, and clear communication.

Production & Quality Control
Our factory teams operate automated enamelling lines with real-time monitoring. Each batch is tested for film continuity, dielectric strength, and thermal performance before leaving the facility.

Technical Support
Our engineers have years of experience in magnet wire applications. They work closely with clients to verify specifications, suggest alternatives, and resolve technical questions quickly.

Sales & Logistics Coordination
Our export team handles documentation, shipping, and customs clearance — ensuring a smooth process from order placement to final delivery.

CHINGCUNG Brand Commitment
Under the CHINGCUNG brand, every team member shares one goal: to deliver reliable enameled wires that perform as promised, order after order.
