全流程品控体系 (Our QC Process)

Our company conducts rigorous verification of key components of stair lifts through a closed-loop quality control system. This ensures that every batch of stair lift parts meets precision manufacturing engineering standards in terms of dimensional tolerances and mechanical load strength.

Incoming Quality Control

100% material spectroscopy testing. Every batch of steel, aluminum, or brass is verified before production.

In-Process QC

Real-time monitoring of CNC tolerances. First-article inspection (FAI) for every new setup.

Final Quality Control

Performance and fatigue testing for moving parts like gears and rollers.

Outgoing QC

Export-grade rust-proof packaging and final shipment audits.

Metrology & Inspection Lab

Coordinate Measuring Machine

High-precision 3D geometric dimension inspection, with tolerance control up to ±0.002mm, ensures the precise matching of the elevator's transmission mechanism and guide rails.

Digital Profile Projector

It is used to inspect the cross-sectional geometry of complex metal parts to ensure that details such as threads and tooth profiles meet DFM optimization requirements.

Roughness Tester

Surface roughness testing controls the surface finish of stair lift slides and moving parts, which can reduce operating friction, lower operating noise, and extend the service life of parts.

Spectrometer (PMI)

Spectrometer (forward material identification). It performs chemical composition analysis on raw materials, ensuring that the 7075-T6 aluminum alloy, stainless steel, or special steel used meets design specifications.

Rockwell & Brinell Hardness Testers

Testing the hardness of parts after heat treatment or surface strengthening ensures that the structural components of the stair lift have sufficient load-bearing strength.

Salt Spray Testing Machine

Simulate harsh operating environments to test the corrosion resistance of surface coatings (such as powder coating or electroplating) on metal parts, ensuring that they do not rust during long-term operation.

Service

We create digital design based on UX

We would rather be thought of as a boutique of digital art than a factory which exceeds its capacity.

Core Technical Backing

Linear Tolerance: Consistently maintained between ±0.01mm and ±0.05mm. Geometric Tolerance: Flatness, cylindricity, and symmetry are controllable within 0.02mm. Surface Finish: Supports Ra 0.4 / Ra 0.8 / Ra 1.6 to ensure the mechanical efficiency of the drive system.

Industry Compliance & Reliability

Fatigue Testing：We perform cycle testing for critical load-bearing parts (up to 50,000 cycles) to simulate a 10-year stairlift lifespan. Traceable MTRs：Every shipment includes a 3.1 Certificate (Material Test Report) as per EN 10204, ensuring chemical and physical properties are verified.

Quality Assurance & Technical FAQ

Addressing common manufacturing standards and technical inquiries for stairlift components.

How do you ensure the mechanical precision of critical stairlift components?

We utilize high-precision CNC machining centers to manufacture rail brackets, drive gears, and pivoting components. Our tolerances are strictly controlled within ±0.005mm, and every batch undergoes full-dimensional inspection via CMM (Coordinate Measuring Machines) to ensure seamless integration and smooth operation within the lift system.

Are the materials used for stairlift parts compliant with international safety standards?

Absolutely. We provide full material traceability with Mill Test Reports (MTR) for all metals, including high-grade aluminum, stainless steel, and alloy steels. For polymer components like guide rollers, we use wear-resistant, high-load-bearing plastics that meet global safety regulations for passenger transport equipment.

How do you guarantee the service life of high-frequency transmission parts?

Transmission parts such as gear racks and pinions undergo specialized surface hardening treatments (e.g., induction hardening or carburizing) to enhance fatigue resistance. We conduct rigorous durability testing to simulate long-term load cycles, ensuring minimal noise and maximum reliability over tens of thousands of operations.

What quality management systems are in place at your facility?

Our production facility is ISO 9001:2015 certified. We implement a strict quality control loop that includes Raw Material Inspection, First Article Inspection (FAI), In-process Quality Control (IPQC), and Final Inspection (FQC) to ensure 100% compliance with your technical specifications.

Can you provide customized manufacturing based on our specific designs?

Yes. Our engineering team offers comprehensive DFM (Design for Manufacturing) support. We can manufacture directly from your CAD or 3D models and suggest optimizations in material selection or processing methods to improve part performance while maintaining cost-efficiency for your project.
