Medical

Silicone rubber is frequently used to manufacture high-quality healthcare, industrial, and consumer products. Medical-grade silicone rubber is a specialized material that meets strict medical standards for safety and is used to create flexible, durable medical components.

At Jefferson Rubber Works, Inc., we offer premier medical silicone injection molding services for the medical industry, using fully traceable medical-grade silicone in our products. Our liquid silicone rubber (LSR) injection molded parts and processes adhere to strict ISO standards.

Learn more about our LSR injection molding process, the types of parts we produce, our silicone materials, and more.

Our Process

An ISO 13485:2016 certified manufacturer, Jefferson Rubber Works, Inc. operates a controlled environment Class 8 injection molding cleanroom. Our Medical Products Group provides contaminant-free, flash-less LSR and elastomeric components for various healthcare applications.

We utilize state-of-the-art injection molding equipment that allows us to produce at much higher rates than compression molding processes and with a superior degree of accuracy. Our modern facilities can manage small- to large-volume production runs, prototyping, design consultations, secondary finishing, and assembly.

The LSR Injection Molding Process

The injection molding of liquid silicone rubber involves combining part A (the base polymer) and part B (the cure system) and molding the mixture into specific shapes. The following is our liquid silicone injection molding process for manufacturing medical device components.

We take a holistic approach to LSR molds, collaborating with our clients to develop innovative tooling that meets their specific requirements.

We help you choose the correct silicone material type for your medical components.

Our team produces your LSR injection molded components in a cleanroom environment, with strict procedures in place to reduce the risk of contamination from dust and other particles.

Jefferson Rubber Works, Inc. labels and assembles your silicone rubber molded parts as needed, completing your project with enhanced cost savings, quality, and efficiency.

Benefits of Liquid Silicone Rubber Injection Molding

Medical silicone injection molding processes from Jefferson Rubber Works, Inc. provide the following advantages:

Diverse Applications

The LSR injection molding process is often utilized in the healthcare industry and other mission-critical applications.

Design Flexibility

Injection molding LSR offers greater design flexibility than elastomers since liquid silicone can fill complex part geometries with tight tolerances.

Biocompatibility

Our LSR products are suitable for short- and long-term patient implants, due to their odor-free, stain-resistant, bacteria-resistant, and easy-to-sterilize properties.

Automation

LSR injection molding is an automated process that uses advanced production techniques in a cleanroom setting. It is designed to reduce the potential risk of contamination and human error.

Extended Product Life

Jefferson Rubber Works, Inc. employs the latest tooling, technology, and automation methods to ensure all molded medical device parts remain transparent and resist cracking and scratching throughout their lifespan.

Multi-Material Molding

Certain multi-material LSR molding techniques, such as silicone overmolding, help us reduce costs while maintaining quality and enhancing product performance.
