This is why advanced silicone is the material of choice for a wide range of applications in the healthcare industry. Medical-grade silicone has the ability to withstand extreme temperatures, harsh chemicals, and frequent sterilization.
With advancements in silicone materials, medical device manufacturers can now produce highly specialized medical components with complex geometries to improve patient outcomes.
Here, learn about the latest advancements in silicone molding for healthcare applications, including its manufacturing process, production efficiency, and range of applications.
What Is Silicone Molding?
Silicone molding is a manufacturing process that uses silicone materials to produce medical components, electronic components, and consumer products with intricate geometries and enhanced properties.
Silicone is a synthetic polymer made up of silicon, oxygen, carbon, and hydrogen. It is engineered to create an ideal material for many specialized industries and applications because it exhibits remarkable thermal and chemical resilience, setting it apart from traditional rubber.
Advanced silicones are known for their performance across a vast temperature range (from -100°F to +500°F). They have a non-toxic composition, making them a suitable choice in medical technology.
Types of Silicone Molding
There are several types of advanced silicones on the market used for molding, with the two main ones being liquid silicon rubber and solid silicon rubber. Both have high resistance to extreme conditions and harsh chemicals, but their applications vary because of the nature of their molding process and different limits.
Liquid Silicone Rubber (LSR) Molding
LSR molding is a widely used medical molding technique that involves injecting liquid silicone rubber into a heated mold cavity.
This specific type of silicone allows it to be injected into molds for precise shapes and designs. Unlike solid silicone rubber, LSR is processed at a high range of temperatures and can be molded easily into complex forms, offering exceptional performance characteristics.
- Key Benefits of Liquid Silicone Molding:
- High biocompatibility of silicone rubber
- Exceptional resistance to high-temperature conditions
- Precision for medical device manufacturing
- Cost-effective mass production for high-volume production runs
- Common Applications:
- Medical implants, such as breast implants and heart valve components
- Wearable technology, including heart rate sensors
- Drug delivery devices
Solid Silicone Rubber (SSR) Molding
Unlike LSR, SSR molding uses solid silicone rubber, which is heat-cured in a mold.
- Key Benefits:
- Enhanced mechanical properties for demanding applications
- Temperature resistance and improved heat resistance
- Durability under mechanical stress
- Common Applications:
- Dental devices
- Surgical grips and flexible components for medical procedures.
Other Silicone Molding Methods
