Plastic Injection Molding In The Medical Industry

Table of Contents

Injection molding is a widely used manufacturing process in the medical industry, offering numerous advantages for a variety of applications. Medical-grade plastics injection molding is used for medical devices, components, laboratory and facility equipment, and more.


Injection molding is a cost-effective way to mass-produce a silicone or thermoplastic product. It involves the creation of an aluminum tool, also called a mold, that is inserted into an injection molding machine. The mold has two halves, called a core and a cavity, respectively. Our machines exert enormous pressure on these halves to bring them together. Thermoplastic or silicone is then melted and injected into the mold through its gates.

Medical Plastic Injection Molding

Todsilicone provides medical plastic injection molding for components used in end-use medical devices. We also provide medical plastic molding for complex assemblies within different systems.

Materials are selected for physical properties, such as strength and resistance to chemicals, as well as cost and manufacturability. Medical devices involve molding processes, as well as multiple fabrication processes.

Medical injection molding processes are often used for cost-effective production. Medical assemblies can be delivered with different materials through multishot molding and overmolding.

Silicones are often used in medical devices because of their very low solubility and ability to withstand high temperatures and chemicals.

The Benefits of Medical Device Injection Molding

Medical suppliers have found that plastic injection molding medical parts, components and devices is one of the most effective ways to attain the quality and specifications they need in a cost-effective and efficient manner. Medical device plastic injection molding is used for applications such as:

  • Implantable components
  • Beakers, test tubes and other containers
  • Surgical equipment and components
  • Drug delivery equipment and components

These are just a few of the ways medical device plastic injection molding is used. The process of plastic injection molding medical parts can be applied to nearly any area where durable, sterilization-friendly parts are required at high volume and with exceptional accuracy in production.
