Quality Control
The engineers at Yonglihao Machinery know how to make parts and they take production seriously to deliver high quality products.
Quality Assurance Process
Yonglihao Machinery makes sure to follow strict quality checks when making parts. This guarantees that the parts are of high standards and meet customer expectations.
Demand Analysis:Before preparing the parts, we talk to customers to know what they want and expect. We clarify specifications, design requirements, and quality standards to match the customer’s expectations.
Raw Material Review:In the raw material selection phase, we carefully examine the materials provided by our suppliers. We check if they meet quality and specification standards. Only reviewed raw materials are used for subsequent processing.
Process Control:During the mid-point of part processing, we implement strict process controls. We monitor and document every step of manufacturing to meet set standards and specifications.
Regular quality checks:We regularly inspect the parts using precise tools to check dimensions, tolerances, and surface quality. This helps ensure the parts meet customer requirements and design specifications.
Final Inspection and Testing:Final inspection and testing is carried out at a later stage of part processing. We use advanced testing facilities to make sure the part meets the design criteria.
Quality Reporting and Documentation:Detailed quality reports are generated to document all production and inspection data. The reports are used for internal quality control and to show customers the part quality.
Traceability and Feedback:Create a system to track parts and link them to their production batches. Receive customer feedback, conduct regular reviews, and continuously improve our quality management processes.
Quality Reports
| Sports Event | Description | Charges |
|---|---|---|
| Visual Inspection | We inspect parts to ensure they look perfect, have a smooth surface, and meet requirements. We promptly identify and document any problems that might affect the quality and dependability of the part. | Free |
| Dimensional Inspection | We use precise tools to measure parts and make sure they match the design drawings. Each critical dimension is carefully verified to ensure part accuracy and consistency. | Free |
| Performance Inspection | We perform performance inspections to test the part’s functionality against design specifications. We simulate real-world conditions to make sure the part works well in different environments. | Free |
