Your Trusted Partner for Precision Electromagnetics
As a premier Automotive Solenoid Supplier in USA markets, Weilong Intelligent Technology bridge the gap between high-volume production efficiency and rigorous American engineering standards. Established in 2006, we have spent nearly two decades perfecting the art of electromagnetic actuation.
We provide US-based engineers and procurement specialists with locally-aligned technical support combined with our world-class manufacturing hub. Our focus is on long-term reliability, ensuring every solenoid—from a simple latching mechanism to a complex automotive transmission valve—performs flawlessly under extreme conditions.
Mission: To empower global innovation through stable, efficient, and durable solenoid systems designed for the next generation of smart vehicles and industrial automation.
Comprehensive Solenoid Product Range
We offer a diverse portfolio of electromagnetic components tailored for the US automotive and industrial sectors. Each product is customizable to meet specific voltage, force, and duty cycle requirements.
Frame Push Pull Solenoids
The workhorse of industrial automation. Our Frame Solenoids offer high force-to-size ratios and exceptional durability for repetitive tasks.
Latching Solenoids
Perfect for battery-operated devices. Latching Solenoids maintain position without continuous power, reducing heat and energy consumption.
Tubular Solenoids
Designed for precision and long life. Tubular designs provide quiet operation and are ideal for high-end medical and automotive applications.
Rotary Solenoids
When linear motion isn't enough. Our Rotary Solenoids provide snap-action angular displacement for sorting and shutter controls.
Solenoid Valves
Advanced fluid control. From Automotive Solenoid Valves to irrigation, we ensure leak-proof, high-cycle performance.
Electromagnets
Industrial strength holding power. Our Electromagnets are used in security locks, automation, and material handling.
IATF 16949 Certified Quality
In the automotive industry, there is no room for error. As a leading automotive solenoid supplier, we adhere to the IATF 16949:2016 quality management system. This ensures that every component we ship to the USA meets the stringent safety and performance standards required by Tier 1 and Tier 2 manufacturers.
- Zero-Defect Goal: Implementing rigorous APQP and PPAP processes.
- Full Traceability: Every batch is logged with material and test data.
- Thermal Resilience: Solenoids designed to withstand engine-bay temperatures and vibrations.
- EMI/EMC Compliance: Engineered to integrate seamlessly with modern vehicle ECUs.
Engineering-First Approach
We don't just "sell" solenoids; we engineer solutions. Our R&D team works directly with US design firms to optimize magnetic circuits.
In-House Manufacturing Hub
Unlike many suppliers who outsource components, Weilong maintains full control. We operate our own CNC machining centers, plastic injection workshops, and metal stamping facilities. This Integrated Manufacturing Hub allows us to control lead times and ensure part-to-part consistency that others simply cannot match.
Advanced Laboratory Testing
Our in-house lab is equipped for extreme validation. We perform:
- High/Low-temperature endurance testing
- Salt spray corrosion resistance
- Life-cycle testing (up to 10 million cycles)
- Response time and magnetic force profiling
Custom Solenoid Design for US Markets
Many of our US clients require unique mounting brackets, specialized connectors (like Deutsch or Molex), or specific plunger coatings for low friction. Our Technical Support team provides rapid prototyping and 3D modeling to ensure the solenoid fits your assembly perfectly on the first try.
