Quality assurance and quality control are essential processes across countless industries to ensure goods and products meet the standards put in place by the developing company. From testing the pH levels in personal hygiene products during manufacturing to verifying temperature consistency in packaged food items, quality control ensures the well-being and satisfaction of the end user. When it comes to the creation of medical devices, quality control is exceedingly crucial. Dynamic Group Inc., a trusted provider of the most critical components to the world's leading medical device manufacturers, plays a significant role in this process. In this article, we will explore the significance of quality assurance and quality control measures, specifically during the injection molding process of medical device manufacturing.
Even though they may seem interchangeable, quality control and quality assurance actually play different roles. Quality control is all about the product, while quality assurance focuses on the process. Both are key to making sure the final product meets the specific standards. Quality assurance occurs before and during manufacturing, while quality control occurs during and after.

As described in an article from Qualizeal, one of the main reasons why quality assurance and quality control are essential in medical device manufacturing and testing is the risks that come with faulty devices. Inadequately tested or poorly designed medical devices can lead to significant health risks for patients. According to a report by ECRI Institute, a nonprofit organization that focuses on patient safety, “medical device failures resulted in over 1,900 injuries and 83 deaths in a single year in the United States alone.”
Additionally, the cost of medical device recalls due to quality issues can be staggering. “In 2019, the FDA issued 87 medical device recalls, affecting over 21 million units.” These recalls can result in financial losses and harm to a company's reputation.
In light of this, quality assurance is vital in medical device testing to ensure that devices are both safe and effective for patient use. Quality assurance and quality control processes is the solution that helps manufacturers minimize risks, decrease the chances of recalls, and enhance patient outcomes.
Once a design is approved and the injection molding process begins, one of the first steps is material selection. Material selection is critical because different metals and plastic types must be carefully chosen to ensure the best suitability for the specific device. Then, before injection molding and production begins, pre-production testing is performed to verify that the chosen materials meet all required standards for strength, biocompatibility, and performance.
Additionally, when it comes to medical components and devices, compliance with industry regulations, such as FDA guidelines and ISO 13485, must be met.
Quality assurance techniques and real-time monitoring are used throughout the injection molding process. Some of the methods of doing this include:
- Temperature control
- Flow rate monitoring
- Viscosity measurement
- Mold cavity pressure sensing
- Cycle time tracking
- Part weight measurement
After the injection molding process is complete, quality control inspection takes place to ensure the product meets standards and is compliant. This can include methods such as:
- Visual checks
- Dimensional analysis
- Functionality testing
- Material testing
- Biocompatibility testing
These rigorous quality control practices contribute to reliable and safe medical devices. Quality control and assurance not only help to ensure that molded medical components and devices meet quality and safety standards, but it also contributes to a company's reputation.
