Shanghai Husu M&E Technology Co., Ltd has been a reliable supplier of high-performance enameled wires since 2015. Under our brand CHINGCUNG, we serve global manufacturers with quality products and professional service.
EVMagnetWire.com is our dedicated platform for regular enameled wires — including copper, aluminum, and copper-clad aluminum conductors, with thermal ratings from 130L to 240. Our product range covers polyester, polyurethane, polyesterimide, polyamide-imide, and polyimide insulation systems, complying with IEC, GB, NEMA, and JIS standards.
Unlike our specialty wire platform (chingcung.com) which focuses on self-bonding wires and PMSM motor components, this website is built exclusively for customers seeking standard, off-the-shelf enameled wires for motors, transformers, coils, and household appliances.
Our factories are located in Jiangsu and Zhejiang, equipped with automated painting and baking lines, advanced testing instruments, and strict quality management systems. With a monthly production capacity of 100 tons for regular enameled wires, we ensure stable supply, competitive pricing, and timely delivery to North America, Europe, and Asia.

Company slogan:
A Dedicated Platform for Regular Enameled Wires
OEM Overview:
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:
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.
R&D:
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.
Our Team:
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.
History:
Our Journey – Building Trust Since 2015
2015 – Foundation Shanghai Husu M&E Technology Co., Ltd was established in Shanghai by a team with deep roots in electromechanical trading and manufacturing. We started as a supplier of assembly tools and automated equipment for Chinese manufacturers.
2018 – Expansion With growing demand for high-quality magnet wires, we began investing in enameled wire production facilities across Jiangsu and Zhejiang, focusing on quality control and process automation.
2020 – Global Export Launch We intensified our international sales efforts and built a dedicated export team, quickly gaining traction in North American and European markets under our brand CHINGCUNG.
2024 – Dedicated Platform for Regular Enameled Wires To better serve customers seeking standard, off-the-shelf products, we launched EVMagnetWire.com — a focused platform for regular enameled wires, separate from our specialty wire business.
Today We now produce over 100 tons of regular enameled wires monthly, serving motor, transformer, coil, and appliance manufacturers across the globe.
Service:
What We Deliver – Beyond Just Enameled Wires
We provide more than high-quality regular enameled wires. Our service model is built around responsiveness, transparency, and technical support.
Standard & Custom Specifications
We supply enameled copper, aluminum, and CCA round wires from class 130L to 240, in line with IEC, GB, NEMA, and JIS standards. Custom diameters and packaging are available upon request.
