FAQ

1. R&D: What technology supports the development of this L-shaped torque hinge?

Our L-shaped torque hinge is developed in-house using high-strength carbon steel and engineered specifically for demanding applications such as industrial equipment, control panels, and precision instruments. Our R&D team applies finite element analysis (FEA) and rigorous durability testing to validate performance across 1.0 N·m and 1.5 N·m torque options. We proactively provide detailed test reports to support your application requirements, ensuring smooth motion and reliable free-stop positioning.

2. Customization: Can you offer custom sizes or torque values?

Absolutely. We provide full customization services, including torque values, mounting hole patterns, surface finishes, and left/right configurations. Whether you require higher torque capacities, corrosion-resistant coatings, or non-standard dimensions, our engineering team actively works with you to review drawings and confirm specifications before production. We ensure your custom carbon steel torque hinge integrates seamlessly with your equipment design.

3. Factory: Where are these hinges manufactured, and what quality controls are in place?

All hinges are manufactured in our ISO 9001:2015-certified facility, where we operate automated stamping and precision assembly lines. Our quality assurance team implements 100% torque consistency testing and life-cycle validation throughout production. By maintaining full in-house manufacturing control, we actively guarantee stable quality, consistent performance, and traceability for every industrial hinge we deliver.

4. Shipping: What are the lead times and shipping options?

For standard models (1.0 N·m / 1.5 N·m, left and right versions), we maintain in-stock availability and ship within 1–3 business days after order confirmation. We partner with FedEx, DHL, UPS, and other reliable carriers to offer domestic and international shipping options. For custom orders or bulk quantities, we proactively coordinate production schedules and offer partial shipment options to keep your project timelines on track.

5. Returns: What is your return policy if the hinge does not meet application requirements?

We offer a clear and customer-focused return policy. If you experience manufacturing defects or if a custom configuration fails to meet mutually confirmed functional requirements, we support returns within 30 days of receipt. To help you avoid compatibility issues, we strongly encourage sample testing before bulk ordering. Our sales engineers actively assist with pre-purchase fit verification and torque validation to ensure the right solution from the start.
