About JAN

Founded in Dongguan, China, JAN is a precision manufacturer specializing in precision torque hinges and rotary dampers, delivering reliable motion control solutions for global OEM customers.

We understand the critical role a reliable damper plays in your product’s functionality, user experience, and overall quality. That’s why we’ve built our entire operation around solving the most common and costly pain points faced by OEMs and engineers worldwide.

Beyond the Specification Sheet: We Deliver Consistency.
We know your concerns:

  • Lifetime
  • Torque instability from batch to batch
  • Oil leakage after thousands of cycles
  • Premature wear
  • The frustration of delayed shipments that stall your production line.

 

At JAN, we address these challenges at our core. ISO 9001-certified processes, from raw material sourcing to 100% automated torque testing, ensure that every damper be shipped meets its specified performance—every single time. Our in-house laboratory validates longevity with rigorous cycle testing (20,000 to 50,000+ cycles) under varied temperatures (-20°C to 70°C), providing you with data-backed confidence, not just promises.

Partner with JAN for motion that feels right, lasts long, and integrates seamlessly. Let’s discuss how our dampers can enhance your project.

From Raw Materials to Final Inspection:
A Process Built on Data

Our Manufacturing Philosophy:
Control the Process, Guarantee the Outcome

Inconsistent dampers are a symptom of uncontrolled processes. At JAN, we have built our 6,000 sq. meter facility around a single principle: data-driven control at every critical stage. This is how we move from uncertainty to statistical confidence.
Process Steps (Timeline Component):

1. Raw Material IQC: We don’t trust supplier certs alone. We perform our own verification on all incoming batches of steel, plastic resins, and sealing components.

(So what?) This means your damper’s housing won’t crack and its gears won’t wear prematurely.

2. Automated Assembly & Silicone Oil Filling: Our automated lines ensure every damper receives the precise volume of high-quality silicone oil, critical for consistent torque.

(So what?) This eliminates the primary cause of torque variation across a batch.

3. 100% Automated Torque Testing: Every single unit is tested for its torque profile. No random sampling.

(So what?) This means the 10,000th part you receive will perform identically to the first, eliminating the need for you to perform incoming QC.

4. 100% Seal Integrity Testing: We use multi-stage air pressure tests to validate every seal.

(So what?) This is our Zero-Leak Guarantee. You can design our dampers into your product with full confidence against contamination.

Custom Solutions, Grounded in Manufacturing Reality

We are more than a supplier; we are a DFM partner. Our engineering team, with expertise in
both damper design and high-volume manufacturing, works with you to create solutions
that are not only functional but also cost-effective and reliable to produce at scale.

Our Customization Process:

1. Requirement Analysis: We analyze your torque, angle, space, and lifecycle needs.

2. Design & Simulation: We create 3D models and perform initial simulations.

3. Rapid Prototyping: Functional prototypes in as little as 15 days.

4. Tooling & Mass Production: Seamless transition to our automated production lines.
