Custom Solenoid Manufacturer in China

Empowering global industries with precision-engineered electromagnetic solutions. From rapid prototyping to high-volume manufacturing, Weilong Technology is your trusted partner for IATF 16949 certified custom solenoids, solenoid valves, and inductor coils.

Why Choose a Custom Solenoid Manufacturer in China?

In the rapidly evolving landscape of industrial automation, automotive engineering, and medical device manufacturing, off-the-shelf components often fall short. Designing complex systems requires actuators that perfectly match your specific voltage, duty cycle, stroke length, and force requirements. This is where partnering with a specialized Custom Solenoid Manufacturer in China becomes a strategic advantage.

Weilong Intelligent Technology Co., Ltd., established in 2006, bridges the gap between innovative engineering design and cost-effective mass production. Over the past two decades, the Chinese manufacturing sector has transformed from simple assembly into a high-tech hub of AI-driven production and precision engineering. We leverage robust local supply chains for raw materials—such as high-grade copper wire and premium magnetic steel—combined with advanced manufacturing technologies to deliver unparalleled value.

Our Core Philosophy: We do not just manufacture parts; we engineer reliability. By integrating structuring design, prototyping, tooling, testing, and volume production under one roof, we eliminate supply chain fragmentation and ensure absolute product consistency.

Professional Solenoid Manufacturers-- Weilong Company Factory Tour

20 Years of Focus on Solenoid Technology

Since our inception, Weilong has concentrated exclusively on solenoid, inductor coil, and electromagnetic actuator technology. We actively participate in the industry's evolution, moving from standard solenoids to highly reliable, fast-response, and application-specific solutions.

🧲

Magnetic Circuit Design

Optimizing the magnetic flux path is crucial for maximizing force while minimizing energy consumption and heat generation. Our engineering team utilizes advanced simulation software to design efficient magnetic circuits tailored to your spatial constraints.

🌡️

Thermal Management

Solenoid temperature rise is a primary cause of failure in high-duty applications. We meticulously select high-temperature insulation materials, specialized bobbins, and implement structural designs that dissipate heat effectively, ensuring long lifetime performance.

⏱️

Response Time Control

For applications like sorting machines or automotive fuel injection, milliseconds matter. We engineer armatures and springs to achieve ultra-fast actuation and release times, maintaining force consistency across millions of cycles.

In-House Manufacturing Hub

To guarantee consistent quality and stable delivery times, Weilong operates a fully Integrated Manufacturing Hub. Relying on external suppliers for critical components introduces risks. Therefore, core solenoid components—such as iron cores, armatures (plungers), housings, and bobbins—are processed entirely in-house.

  • CNC Machining Centers: Precision turning and milling for armatures to ensure micro-level dimensional accuracy, reducing friction and wear.
  • Metal Stamping Facilities: High-speed stamping for frames and housings, ensuring structural integrity and magnetic permeability.
  • Plastic Injection Workshop: Custom molding for bobbins and encapsulations, using flame-retardant and high-durability polymers.
  • Coil Winding Automation: AI-monitored winding machines that guarantee exact turn counts and perfect tension, preventing electrical shorts.

This direct integration allows us to seamlessly transition from rapid prototyping to mass production, significantly cutting down lead times for our global clients.

Built-in-House Laboratory Testing

Meeting the stringent reliability requirements of US and European buyers requires empirical data. Our dedicated testing center conducts:

  • Pull and push force mapping across the entire stroke.
  • Actuation stability and response time measurement.
  • Temperature rising and thermal endurance (burn-in) testing.
  • Lifespan durable performance testing (often exceeding millions of cycles).
  • Salt spray testing for corrosion resistance in harsh environments.

Comprehensive Solenoid Solutions

As a top-tier Custom Solenoid Manufacturer in China, our product portfolio spans across various types of electromagnetic actuators. Whether you need a standard frame solenoid or a highly complex automotive proportional valve, we have the technological foundation to deliver.

Frame Push Pull Solenoids

The most versatile and cost-effective linear actuators. Our Frame Solenoids are widely used in vending machines, gaming equipment, and industrial automation due to their open-frame design allowing excellent heat dissipation.

Latching Solenoids

Designed for energy efficiency. Latching Solenoids use permanent magnets to hold the plunger in place without continuous power. Ideal for battery-operated devices, smart locks, and aerospace applications.

Tubular Solenoids

Enclosed in a cylindrical metal case, Tubular Solenoids offer maximum magnetic efficiency, long stroke capabilities, and quiet operation. Perfect for medical devices and high-end consumer electronics.

Rotary Solenoids

Converting linear magnetic force into rotational motion. Our Rotary Solenoids deliver high-speed, snap-action torque for laser shutters, sorting gates, and material handling systems.

Solenoid Valves & Automotive

Precision fluid and gas control. From Solenoid Valves for irrigation to strict Automotive Solenoids for transmissions, manufactured under IATF 16949 standards.

Electromagnets & Locks

High holding force solutions. We manufacture heavy-duty Electromagnets for robotics and secure Solenoid Locks for smart cabinets, lockers, and access control systems.
