The quality control process for TWITTER bicycles is designed to ensure that the final product meets safety, performance, and reliability standards.
Suppliers must pass ISO 9000 quality system certification.
Regular assessments are conducted on suppliers regarding their production capacity, technical level, quality assurance capabilities, business performance, and social responsibility to ensure ongoing and stable cooperation.
Suppliers are expected to collaborate on continuous product quality improvement, cost reduction, and efficiency enhancement in delivery.
Inspection standards are determined and executed based on the supplier's quality assurance capability level to prevent the use of non-conforming components (such as carbon fiber frames, wheelsets, hubs, Cassettes, Derailleurs, disc brake calipers, etc.).
Non-conforming items are isolated, identified, and disposed of promptly.
Manage the skill level of employee operations, with designated personnel for key processes.
Regular inspections of production equipment, and periodic calibration of measuring instruments (such as torque wrenches, micrometers, etc.).
Employees assemble according to standardized work documentation and widely adopt mistake-proofing techniques (such as positioning jigs), ensuring each assembly step meets process and technical requirements.
In-process control includes self-inspection by employees, mutual inspection between processes, patrol inspections by dedicated quality inspectors, and 100% inspection of key processes (Bottom bracket assembly, Wheel truing, Derailleur installation and adjustment, hydraulic brake bleeding, and performance inspection).
A comprehensive inspection is conducted after the TWITTER cycles are completed to ensure it meets quality standards.
Regular internal quality audits are conducted to assess the effectiveness of the quality control process.
The quality control process is continuously improved based on quality data and customer feedback.
The quality control process for TWITTER carbon fiber bicycles is designed to ensure that the final product meets safety, performance, and reliability standards.
