One of the most important steps forward in the production of medical devices has been the ability to create specific types of materials that are ideally suited to use both inside of the human body as well as outside. The thermoplastic and thermosetting polymers available today offer completely non-reactive materials that have a long-life cycle and are completely resistant to any breakdown in the body or with exposure to chemicals outside of the body.
These devices are formed through a process known as medical injection molding. As the name implies, the liquid polymer is injected, under pressure, into the mold, allowing for even and rapid distribution throughout the mold, even in very tiny cavities for precise production with every cycle.
Important Considerations
When selecting a company for medical injection molding, it is essential to partner with a manufacturer with extensive experience in producing parts for the medical field.
These companies have a full understanding of the FDA requirements and standards for production, as well as all verification required throughout the product development and approval steps. This is critical for the OEM as companies without this expertise may develop processes or even use materials that are not approved or that cannot be verified.
The company providing medical injection molding can also be instrumental in assisting with design and engineering support. Through their experience and expertise with the molding process, they can often make suggestions to improve on the design, making it more effective to produce while potentially also decreasing the cost per unit for manufacturing.
The use of injection molding in the production of medical devices offers benefits for both the OEM as well as the patient. This is a highly versatile production option providing quality, durable parts or complete devices with long life cycles.
