Quality control process
Through the quality control process, we ensure that the materials entering the production phase meet quality standards, thereby reducing risks during the production process.
1.Incoming Material Inspection (IQC)
Incoming material inspection is the primary control point for preventing non-conforming materials from entering the production process.
(1) Incoming Inspection Items and Methods:
Appearance:Verified through visual inspection, tactile assessment, and comparison with samples.
Dimensions:Verified using tools such as calipers and micrometers.
Characteristics:Testing of physical, chemical, and mechanical properties, typically using testing instruments and specific methods.
(2) Material Inspection Methods:
100% Inspection: All incoming materials are checked.
Sampling Inspection: Random samples are selected for inspection.
(3) Handling of Inspection Results:
Receiving: Materials that meet standards are accepted.
Rejection: Non-conforming materials will be returned.
Concessional Acceptance: Under special circumstances, materials that do not fully meet standards may be accepted under specific conditions.
100% Re-inspection: All materials are re-checked, and non-conforming items are returned.
Rework and Re-inspection: Materials that have been reworked are inspected again.
(4) Standards:
Technical standards for raw materials and purchased components.
Incoming inspection and testing control procedures.
Physical and chemical testing procedures, etc.
2. In-Process Quality Control (IPQC)
In-process quality control refers to the quality management of all stages of production, from material receipt to finished goods storage, ensuring that the product quality at each stage meets the standards.
(1) Main Inspection Methods:
First Article Inspection, Mutual Inspection, and Special Inspections: Comprehensive checks and validations of the first article produced.
Process Control: Combining sampling and patrol inspections to ensure stable quality during production.
Consolidated Inspection Across Multiple Processes: Centralized checks of multiple processes to improve efficiency.
Step-by-Step Inspections: Quality checks conducted at different stages of production.
Post-Completion Inspection: Final checks conducted after product completion.
Combination of Sampling and 100% Inspection: Selecting appropriate inspection methods based on needs.
(2) Process Quality Control (IPQC):
Conducting patrol inspections throughout the production process, including:
First Article Inspection: Checking compliance of the first article produced.
Material Inspection: Ensuring the quality of materials used.
Inspection:Ensuring appropriate inspection timing and frequency, strictly following inspection standards or work instructions. This includes:
Product quality
Process specifications
Machine operation parameters
Material placement
Labeling
Environmental conditions
Inspection Records: Should be accurately filled out to ensure traceability.
(3) Final Product Quality Inspection (FQC):
This is the quality verification for completed products to determine if the batch can proceed to the next process, classified as point inspection or acceptance inspection.
Inspection Items: Appearance, dimensions, physical and chemical properties, etc.
Inspection Method: Generally conducted using sampling inspection.
Handling of Non-conformities: Addressing non-conforming products appropriately.
Records: All inspection results should be documented in detail.
(4) Standards:
Work instructions
Process inspection standards
Process inspection and testing procedures, etc.
3. Final Inspection Control: Outgoing QC
Final inspection control, also known as outgoing quality control (Outgoing QC), focuses on the quality assessment of finished products before they are shipped. This step is crucial to ensure that only products meeting quality standards reach customers.
(1) Inspection Objectives:
Ensure that the finished products conform to specifications and quality standards.
Identify any defects or issues that may have occurred during production.
(2) Inspection Methods:
Visual Inspection: Check for surface defects, labeling, and packaging quality.
Dimensional Inspection: Verify that products meet specified dimensions using appropriate measuring tools.
Functional Testing: Ensure that the products perform as intended under operational conditions.
Sampling Inspection: Implement statistical sampling methods to assess product quality based on a predefined acceptance level.
(3) Handling of Non-Conformities:
Rework: Products that can be repaired or adjusted to meet quality standards.
Rejection: Products that cannot be corrected will be rejected and documented.
Quarantine: Non-conforming products may be placed in quarantine until a decision is made regarding their disposition.
(4) Documentation:
Maintain detailed records of inspection results, including pass/fail rates, types of defects, and corrective actions taken.
Ensure traceability of each batch of products through proper documentation.
(5) Standards:
Quality assurance standards specific to the industry.
Outgoing inspection procedures and guidelines.
By implementing effective outgoing quality control, manufacturers can ensure that only high-quality products are delivered to customers, thereby enhancing customer satisfaction and reducing returns or complaints.
4.Feedback and Handling of Quality Anomalies
(1)Observable Anomalies:Immediately notify the operator or workshop and take appropriate measures.
(2)Unobservable Anomalies:Present the defective sample to the supervisor for confirmation, then notify for correction or handling.
(3)Record Anomalies:Accurately document all anomalies for subsequent analysis and improvement.
(4)Confirm Corrective or Improvement Measures:Confirm the corrective or improvement measures taken, and track the effectiveness to ensure the issue is effectively resolved.
(5)Identification and Isolation:
Inspection of semi-finished and finished products should have clear markings, and relevant departments should be supervised to ensure isolation and proper storage.
5. Quality Records
Quality records provide objective evidence of completed quality operations and results.
(1) Recording Requirements:
Accuracy: Ensure that the recorded content is true and correct.
Timeliness: Fill out and update records promptly.
Clarity: Use easily understandable language to avoid ambiguity.
Completeness: Ensure that all relevant information is recorded and stamped or signed for confirmation.
(2) Organization and Storage:
Promptly organize and archive all quality records to ensure systematic and retrievable information.
Store records in an appropriate environment to prevent damage or loss.
