Metals: Quality Control
Design & Technology: AQA GCSE, topic 4.9.1
Quality Control
Quality control helps to maintain the desired standards when working with metal. There are a number of ways to ensure quality control.
Establish quality standards
- Define specific quality standards for the metal products or components.
- Quality standards act as benchmarks for evaluating the quality of the finished product.
- Quality standards include dimensions, tolerances, surface finishes and material properties.
Quality management systems
- Implement a quality management system (QMS).
- For example, ISO 9001.
- The QMS provides a framework for consistently achieving quality objectives.
- The QMS includes procedures, processes, and documentation.
- These ensure adherence to quality standards.
Inspecting and testing
- Conduct regular inspections and testing of metal materials.
- Inspecting and testing help to identify any defects, deviations, or non-conformities.
- Inspection and testing include:
- Dimensional inspections.
- Visual inspections.
- Non-destructive testing.
- Mechanical testing.
Process control
- Implement process controls to ensure consistency in metalworking.
- Process control helps to minimise defects during manufacturing.
- Process controls monitor critical process parameters.
- For example, temperature, pressure, speed, and tooling conditions.
Calibration of equipment
- Regularly calibrate the equipment used in metalworking.
- The calibration of equipment ensures the accuracy of measurements.
- Calibrated equipment helps to maintain quality control.
