Plastic injection molding is used in many different applications within the medical industry. Examples include enclosures for medical equipment, the overmolding of surgical tools, and spinal implants. Designers have a choice of materials, but the selected plastic must meet the application’s requirements. For example, plastics that will be sterilized with steam need to resist high temperatures and moisture, while those that will come into contact with patients must be biocompatible, meaning that they’re not harmful to living tissue.

In addition to its excellent molding capabilities, PS also exhibits outstanding impact resistance and temperature resistance. These properties make it the preferred material across industries.

For designers, it’s important to remember that not all polymers are suitable for medical devices. However, injection molding supports the use of many different materials, typically commodity plastics but also specialty plastics and polymer blends. Designers can also choose medical plastics that have specific trade names like ULTEM®, a polyetherimide (PEI) that can withstand repeated cycles in an autoclave. Below are some common injection molding plastics and their salient characteristics:

The mold temperature for polystyrene typically ranges between 20°C and 70°C. The exact temperature depends on the specific type of PS used and the desired properties of the final part.
