Plastic Injection Molding & Quality Control

Quality control is the most important part of plastic products manufacturing. It aims to optimize the plastic products process to reduce the number of defective products produced, and also prevent the distribution of defective parts or component to customers.

  • Advanced Quality Planning (AQP )
  • Computer Aided Quality (CAQ )
  • Continuous Process Control (CPC)
  • Statistical Process Control (SPC)
  • Statistical Quality Control (SQC)
  • Totally Integrated Automation (TIA)
  • Total Quality Management (TQM)
  • Failure Mode and Effects Analysis (FMEA)

Key techniques for quality control in plastics manufacturing include stereoscopic microscope, twin-ring LED illumination,  extended depth of field, non-contact video measuring systems,  phase contrast, non-contact z-height measurement, through-the-lens laser auto focusing , polarizing microscopy,  laser scanning and automated edge detection, etc.
