About Weilong

A Leading Professional Solenoid Manufacturer with In-House R&D & Testing

Weilong Intelligent Technology Co., Ltd., established in 2006, is a leading professional solenoid and solenoid valve manufacturer. We specialize in structuring design, prototyping, tooling, testing, and custom development of electromagnetic solenoids, solenoid valves, and inductor coils in the same room.

Drawing on almost two decades of experience in the solenoid industry, Weilong offers dependable, high-performance solenoid solutions to global customers, serving sectors like automotive solenoids, industrial automation solenoids, new energy solenoid valves, smart home solenoids, and medical solenoids for all kinds of devices.

As an engineering-focused solenoid factory or solenoid supplier, we prioritize long-term reliability, product consistency, and application-specific design. Our target extends beyond simply manufacturing solenoids but aims to assist customers in creating stable, efficient, and durable solenoid systems when they are working with us.

With 20 Years of Focus on Solenoid Technology

Since our establishment, Weilong has concentrated exclusively on solenoid, inductor coil, and electromagnetic actuator technology. Based on the past two decades of experience, we have actively participated in the evolution of the industry—from standard solenoids to high-reliability, fast-response, long-life, and application-specific solutions.
Our accumulated expertise covers key engineering areas such as:

Magnetic circuit design optimization

Material selection and structural design solution

Force consistency and response time control system

Thermal management and lifetime performance testing

Mass-production stability and process control management

This deep technical foundation allows us to quickly understand customer requirements and provide verified, manufacturable, and scalable solenoid solutions.

Integrated Manufacturing with Full Control of Key Components

To make sure of consistent quality and stable delivery, Weilong has set up a fully integrated manufacturing system, including CNC machining centers, metal stamping facilities, and a plastic injection workshop. Core solenoid components processing—such as iron cores, armatures/solenoid plungers, housings, and bobbins—is designed and produced in-house. The direct full integration enables us to:

Maintain strict control through material and dimensional consistency during project validation

monitor the supply chain risks and the part lead times

Make sure stable performance across mass production

Support quick customization and project development

Our one-stop service of plastic and metal tooling and stamping teams allows Weilong rapid transition from design to prototype and from validation to volume production.

Built-in-House Laboratory Testing Capabilities

Ensuring Precision for Electromagnet Durable Performance
In order to meet the stringent reliability requirements of customer automotive and industrial solenoid project applications, Weilong operates a dedicated in-house solenoid laboratory and testing center. Our lab supports project validation, project specification checking, and ongoing production quality control.

Weilong's testing capabilities include:

Both Pull and push force of electromagnetic normal performance testing

Responding time and actuation stability measurement

Temperature rising and thermal endurance testing

Product Lifespan: durable performance testing and on/off durability testing

Consistency sampling and stable performance verification for each solenoid undergo a strict testing process—design validation, in-process inspection, and final product verification—to ensure it meets our stringent performance, durability, and reliability standards. The product or part test data is fully traceable, which allows for customer engineering checking and validation.

Weilong’s strength is based on its experienced R&D team, led by engineers with over two decades of solenoid industry experience. Our dedication to ongoing innovation in solenoid and solenoid valve design, energy efficiency, and structural integrity allows us to address the requirements of challenging applications.

Our values

Weilong Values– Driven by Quality, Powered by Engineering

Chapter 1: Engineering-Driven • Quality-Focused • Long-Term Partnership

In Weilong Intelligent Technology Co., Ltd., our corporate values are based on nearly 20 years of commitment to solenoid technology. As a solenoid manufacturer catering to the global industrial sector, we firmly believe that good products require good values, good processes, and long-term thinking.

The culture we come from determines the types of solenoids we design and build.

Chapter 2: Our Mission

For Building Dependable Solenoid Solutions for Critical Use-Cases

Our mission is to develop and produce reliable, DUBS, and application-specific solenoids that enable customers to develop efficient, safe, and lasting systems.

Rather, we are not after temporary success in the following:

Engineering Feasibility

Long-term performance

Manufacturability and consistency

Cooperating with customers sustainably

Each solenoid that we make is designed to be reliable and function properly throughout its lifespan.

Chapter 3: Our Vision

The goal is to become the “go-to” global partner for solenoid production. We aspire to be a reliable source for automotive, industrial automation, and new energy customers worldwide.

Our vision goes beyond simply supplying products; we aim to be recognized for:

Engineering expertise

Manufacturing precision

Quality consistency

Professional and Open Collaboration

Trust is established with results, not with words.

Chapter 4: Our Core Values

4.1 Engineering First

Engineering can be considered the foundation for all reliable solenoids.

Right from designing a magnetic circuit to the designing of the structure, each aspect is done on the basis of certain engineering principles and applications.

4.2 Quality without compromise

Quality is not an inspection method—it is a system.

We integrate quality control in the area of design, materials, processes, testing, and traceability in order to achieve reliable performance in mass production.

4.3 Responsibility and Reliability

What we make, we stand behind. Each solenoid that goes out the door is manufactured to exact specs and standards of quality. Our dedication to reliability is our commitment to our customers and the industries we serve.

Chapter 5: Continual Improvement

Technology, processes, and markets are constantly evolving. So are we. Ongoing enhancement of our research & development processes, our manufacturing processes, our testing facilities, & quality management systems enable us to improve our products & manufacturing processes.

Long-Term Partnership

We emphasize long-term partnerships over short-term agreements. In understanding our customers’ needs and issues that affect them, we aim to establish partnerships that are anchored on trust, technical support, and success.

Chapter 6: Culture in Action

Our core values are reflected in the way we conduct ourselves in our daily operations:

Engineers and the manufacturing staff collaborate to verify that all products are made as they are supposed to be made. Quality data receives extensive attention with the ultimate goal of preventing defects from occurring in the first place rather than detecting them retroactively. Laboratory testing is conducted to verify their performance, both prior to and in the process of volume manufacturing. Consumer feedback is viewed as an opportunity for improvement rather than as something to be avoided.

It is this approach that makes our solenoids function properly in practical applications.

Chapter 7: Humans and Teamwork

Experience, Discipline, and Cooperation

Weilong also employs a staff of skilled engineers, technicians, and quality specialists. “It’s the team effort and the rigor we bring to the process that allows consistency, even for complicated or customized projects.”
