Quality Assurance

Independent quality inspection room

The quality of your casters is fully guaranteed from the moment you place the order. Each product undergoes a closed-loop inspection before it is shipped. Multiple departments, including the technical department, the production department, and the quality center, work together to ensure the quality of our products.

Standard Procedures

Inspection of Incoming Materials

Raw materials are procured through a strict process and tested for quality, compatibility, and longevity with the purpose of ensuring smooth production and high quality of casters. All the raw materials needed for production are stored in an efficiently managed warehouse.

Process Inspection

The injection molding process and the stamping and welding procedures are of great importance when it comes to the production of quality casters. For this reason, these procedures must pass severe testing. Each process is inspected by a special technician who records all the parameters in order to ensure the stability and sturdiness of the casters.

Semi-finished Inspection

Technicians will carry out inspection at the semi-finished product stage, mainly to check the riveting of casters and shelves. This  is necessary to ensure that the casters are well matched before entering the assembly process.

Finally, the overall quality of the finished casters will be fully examined and controlled. Various properties such as wear resistance, waterproof properties, and impact resistance, as well as other aspects, need to be verified before the final products can be shipped in boxes.
