Quality Assurance
Product design and development: During the design phase of the central control rotary platform, a team of professional engineers gathered together to use advanced computer-aided design (CAD) and simulation analysis software to perform fine simulation and optimization of core parts such as product structure, power transmission, and control logic to ensure the reliability and stability of product performance from the source. All design plans must undergo multiple rounds of internal review and test verification before they can enter the production stage.
Raw material procurement: Strictly screen raw material suppliers to establish long-term, stable and high-standard cooperative relationships. For each batch of raw materials, strict quality inspections are carried out, covering the composition analysis of metal materials, mechanical performance testing, electrical parameter testing of electronic components, reliability testing, etc. Only raw materials that meet or exceed industry standards will be allowed to be put into production to ensure the basic quality of the product.
Production process control: The production workshop operates in accordance with a strict quality management system, introduces automated production equipment and high-precision testing instruments, and realizes the standardization and refinement of the production process. At each key node of production, quality inspection points are set up to conduct real-time sampling and full inspections of semi-finished products, including component processing accuracy inspection, assembly quality inspection, and initial electrical performance testing. For quality problems that occur during the production process, the traceability and rectification mechanism is immediately activated to ensure that the problematic products do not flow into the next link.
Finished product inspection: Each central control rotary platform must undergo a comprehensive and rigorous finished product inspection process before leaving the factory. Inspection items include but are not limited to no-load operation test, full-load operation test, positioning accuracy test, repeated positioning accuracy test, noise and vibration test, electrical safety performance test, etc. Only equipment whose indicators fully meet the product quality standards will be labeled as qualified and allowed to leave the factory.
