Medical Device Molding

Molding Expertise and Capabilities for Tackling Even Your Most Complex Medical Devices

Lubrizol Life Science Health (LLS Health) understands that every medical molding project is unique. Whether your project requires a high- or low-volume run, features a component that has been in production for years or one that hasn’t left the prototyping stag, LLS Health brings medical device molding technological expertise and practical execution to handle the full spectrum of your molding needs.

Automated and Efficient Liquid Injection Molding (LIM)

Liquid Injection Molding is the ideal medical silicone molding process when volume, speed, and precision are critical. The ability to run with a lower injection pressure means less variation, tighter tolerances, and consistent quality. LIM brings faster cycle rates that fill high-volume orders quickly. Because all of this takes place within a closed system, LLS Health’s clean room molding process is extremely clean. In addition, LLS Health’s LIM lines use fully automated robotic machines and semi-automatic liquid silicone molding equipment to create repeatable precision and manufacturing efficiencies.

Customized Medical Transfer Molding

For shorter production runs or when silicone gumstock is specified, LLS Health offers custom transfer medical molding capabilities. Intricate shape, undercut and thin walls are possible with specially designed molds and the right material. Pre-mixed gumstock is heated, then injected through gates and sprues into the mold cavities at pressures of 2,000 to 8,000 psi. Cycle times are relatively short and custom molds are accommodated with ease. For this reason, transfer molding can be especially useful in medical product development.

Tight-Tolerance, Custom Dip Casting 

Dip casting might be the best manufacturing method for your silicone medical device, depending on your requirements. It is ideal for forming complex shapes, ultra-thin walls, large cavities and low-durometer and low-friction surfaces, as well as medical device prototyping. The process requires special skill, and LLS Health has perfected it. 

High-Quality Insert Molding

The full realization of your device often calls for inserts encapsulated in silicone. Standard medical molding injection presses are not ideally equipped to handle inserts. When your project calls for the insertion of ancillary components into silicone, LLS Health utilizes a variety of molding processing techniques and medical device molding machines that are designed to create the high-quality and securely integrated molded parts.
