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 manufacturers. We specialize in structuring design, prototyping, tooling, testing, and custom development of electromagnetic solenoids, solenoid valves, and inductor coils under same room.
Drawing on almost two decades of the solenoid industry experience, Weilong offer dependable, high-performance solenoid solutions to global customers, serving sectors like automotive solenoid, industrial automation solenoid, new energy solenoid valve, smart home solenoid, and medical solenoid for all kind of the devices.
As an engineering-focused solenoid factory or the solenoid suppliers, we prioritize long-term reliability, product consistency, and application-specific design. Our target extends beyond simply manufacturing solenoids but aim 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 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 the consistent quality and stable delivery, Weilong has set up a fully integrated manufacturing system,including CNC machining centers, metal stamping facilities and plastic injection workshop. Core solenoid components processing—such as iron cores, armatures/solenoid plunger, housings and bobbin —are 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 team allows weilong rapid transition from design to prototype and from validation to volume production.
Built-in-House Laboratory Testing Capabilities
Ensuring Precision for Electromagnet Duable Proformance
In able 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 both R&D project validation, project specification checing and ongoing production quality control.
Weilong 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 undergoes 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 checkin g and validation.
Weilong’s strength based on its experienced R&D team, led by engineers with over two decade 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.
