Weilong pitches custom rotary solenoids for industrial and medical uses

Weilong Intelligent Technology (Dongguan) Co., Ltd. is highlighting its rotary solenoid engineering and manufacturing capabilities as demand grows for compact, reliable motion-control parts. The company says its Dongguan facility supports custom design, testing and production for customers in automotive, industrial automation, smart home, new energy and medical markets worldwide.

Why it matters: - Rotary solenoids are used in equipment where fast, precise rotational motion affects uptime, performance and maintenance costs. - Weilong Intelligent Technology is positioning itself as a partner for custom solenoid design rather than a component-only supplier. - The company says its integrated manufacturing model is intended to improve quality control and speed up iteration for customer projects.

What happened: - Weilong Intelligent Technology (Dongguan) Co., Ltd. outlined its rotary solenoid products and engineering capabilities in a company release dated July 21, 2026. - The company says it has been developing electromagnetic actuators since 2006 and now has nearly 20 years of hands-on engineering experience. - Weilong says it handles structural design, prototyping, tooling, testing and mass production at a single facility in Dongguan, China. - The company says it ships to customers in automotive, industrial automation, new energy, smart home and medical markets worldwide. - More information is available at the company's announcement.

The details: - A rotary solenoid is an electromagnetic actuator that converts electrical energy into rotary motion. - The product line includes pull-type, push-type, bi-directional and latching rotary solenoids. - Pull-type models are described as offering high start torque, small size and fast response time. - Push-type models are described as converting linear pushing force into angular motion. - Bi-directional models can rotate clockwise and counter-clockwise and do not need a mechanical return spring. - Latching models hold position without power and are designed for low standby power use. - Weilong says it supports voltage customization for DC 5V, DC 12V, DC 24V, DC 48V and other customer-specified requirements. - The company says it can build solenoids for rotation angles including 15°, 30°, 45°, 90° and 180°. - Weilong says it customizes shaft design, mounting holes, housing dimensions, connector type, cable length and mechanical accessories. - The company says its manufacturing flow includes metal stamping, tooling development, plastic injection molding, CNC machining, coil winding, electromagnetic assembly and performance testing. - Weilong says quality checks cover incoming material inspection, production testing and final inspection before shipment. - The company says production tests include coil resistance, voltage performance, torque output, mechanical movement and temperature characteristics.

Between the lines: - The pitch reflects a broader market shift toward smaller, more efficient actuators that can be tailored to specific devices. - Weilong is emphasizing engineering depth and process control because those factors can affect torque consistency, thermal performance and service life. - The company’s focus on integrated production suggests it is trying to reduce variability across batches and shorten development cycles. - Claims about repeatability, torque density and lifetime are presented as engineering outcomes, but field performance will still depend on the final application and operating conditions.

What's next: - Weilong says it will continue offering custom rotary solenoid development for customer-specific voltage, angle and mechanical requirements. - The company is likely to keep targeting applications that need compact, reliable motion control, including automation, security, printers and medical devices. - Detailed specifications, application references and engineering support resources remain available through the company website.

The bottom line: - Weilong is betting that custom engineering and tightly controlled manufacturing will matter as much as the solenoid itself in winning industrial customers.
