Company Profile
Established in 1985,a Benchmark in the Magnet Wire Field with Deep Roots:
Since its establishment in 1985, Shenmao has always taken "casting first-class product quality and achieving excellent choices for customers" as the core of its operation. It adheres to the management principles of "quality first, scientific management, continuous improvement, and customer satisfaction", and integrates the core team culture of "gathering talents harmoniously and treating customers with respect" into its development. Combining the expanded production bases in Songjiang, Shanghai and Dafeng, Jiangsu, the company has built itself into a professional global manufacturer of wrapped winding magnet wires, and established a quality benchmark in the industry with its full-industrial-chain strength.
Scale and Strength: Full-chain Layout, Consolidating the Foundation for Cooperation:
-Production Capacity and Scale:It owns over 25,000 square meters of standardized factory buildings, with a designed annual production capacity of 30,000 tons. There are more than 560 employees. The company has established a full-industrial-chain closed-loop from "insulation raw material research and development" to "magnet wire and copper busbar production", and then to "coil, bar manufacturing and stator-rotor subcontracting". It is one of the few enterprises in the industry with the integrated delivery ability of "material-product-service", and can efficiently respond to customers' full-scenario needs from customization to mass production.
-Industry Recognition:Since 2022, it has been continuously rated as one of the "Top 100 Manufacturing Enterprises in Shanghai" and one of the "Top 100 Private Manufacturing Enterprises in Shanghai". The "Gexiang Brand" magnet wire has won the honors of "Shanghai Famous Brand" and "Shanghai Well-known Trademark". Moreover, it has maintained the qualification of "Shanghai High-tech Enterprise" for more than 20 consecutive years. At the same time, it has been rated as a "Specialized and Sophisticated Enterprise" and a "Patent Pilot Enterprise", winning the dual recognition of the market and authorities with its strong strength.
Core Positioning:Focu son Core Fields,Customize Professional Solutions
It focuses on providing overall solutions for key fields such as hydropower, thermal power, nuclear power, wind power, rail transit, industry, and military special motors, including "customized magnet wires, copper busbars, coils, bars, etc.". We are well aware of the harsh working conditions in different fields. With "first-class quality" as the core, we integrate the independently developed equipment technology and technical advantages into product design. Through a multi-series and high-reliability product matrix, we accurately address customers' pain points in extreme environments, high-efficiency energy-saving, safety and stability, etc., ensuring that every order meets customers' needs.
Technology and Quality Control: Strict Control throughout the Chain, Upholding the Quality Promise
Shenmao runs "scientific management and continuous improvement" through the entire production process, and constructs a closed-loop quality control system covering "development-production-inspection-service" to safeguard the quality of every meter of magnet wire:
-Strict Incoming Inspection:Detect the purity of raw materials such as copper rods to ensure the quality of core materials from the source;
-Strict Process Control:The production line is equipped with online laser diameter measurement, real-time voltage withstand monitoring, high-precision visual inspection and other equipment. Combined with the special-person release inspection in each process, lean control of all production links is achieved;
-Strict Out-of-factory Inspection:The finished products need to pass all the performance tests required by customers. At the same time, professional tools such as the 8D problem-solving method and FMEA risk analysis are used to predict process risks and continuously optimize the process, ensuring that each batch of products delivered to customers meets or even exceeds the standards.
Team and Culture:People-oriented,Gathering Quality Synergy
Shenmao firmly believes that "talents are the cornerstone of quality", and builds a core team with vitality, professionalism, and a sense of belonging around the concept of "people-oriented, teamwork":
-Rights Protection:
Implement the SA8000 social responsibility standard, provide compliant benefits, and create a safe, standardized and comfortable working environment, enabling employees to settle down with peace of mind;
-Collaboration and Empowerment:
Through cross-departmental cooperation projects, skill-sharing meetings, team-culture activities, etc., break down communication barriers, cultivate a working atmosphere of "win-win cooperation", amplify the professional value of each member in the joint effort, and build every "line of defense" of product quality with the professional qualities of the team.
