Frequently Asked Questions (FAQs)

This will help you quickly access basic information. If you need more detailed information, please contact us, and we will get back to you as soon as possible.

What types of core stairlift components can you manufacture?

We specialize in the mass production of comprehensive component sets for both curved and straight stairlifts. Our portfolio includes precision gear racks and pinions, aluminum extrusion guide rails, seat swivel mechanisms, DC motor housings, and various safety-critical limit switch brackets.

How do you handle Intellectual Property (IP) and technical drawing protection?

We take confidentiality seriously. We sign formal Non-Disclosure Agreements (NDA) before receiving any drawings. Our internal ERP system features tiered access, ensuring your innovative designs are only accessible to the relevant project team.

How do you ensure quality consistency across large-batch orders?

We implement a rigorous QC process, including First Article Inspection (FAI), in-process random checks, and 100% inspection of critical dimensions. Our facility is equipped with CMM (Coordinate Measuring Machines) and hardness testers to ensure every batch meets your exact specifications.

Do your components comply with international safety standards (e.g., EN 81-40)?

Yes. As a supplier of safety-critical accessibility products, our processes are ISO 9001:2015 certified. For export components, we provide Material Test Reports (MTR) and inspection documentation compliant with European EN 81-40 and American ASME A18.1 standards.

What is the manufacturing tolerance for curved stairlift rails?

Curved rails are our core competency. Utilizing multi-axis CNC machining and advanced 3D bending technology, we maintain tolerances within ±0.02mm at rail connection points. This ensures zero-vibration and maximum smoothness during lift operation.

What is your Minimum Order Quantity (MOQ) for mass production?

As a manufacturing-oriented factory, we optimize costs through volume. Typically, the MOQ for standard components is 100-1,000 units. However, for complex curved rail systems or new R&D projects, we offer flexibility for the initial batch.

Do you support OEM/ODM customized production?

Absolutely. Our dedicated DFM (Design for Manufacturing) team works directly from your CAD drawings for prototyping. From specialized helical gear racks to custom base castings, we provide a one-stop service from initial design to mass production.

Do you offer small-batch trial production (EVT/DVT) for startup brands?

We highly encourage it. We have a dedicated "Agile Workshop" for trial runs of 1-10 sets. We help customers verify manufacturing feasibility and optimize cost structures before moving into full-scale production.
