Medical Molding
Every medical molding project is unique. Whether yours requires a high- or low-volume run. Whether your component has been in production for years, or has never been beyond a prototype. Whether it’s form can be described as simple or intricate complexity. Vesta brings medical molding technological expertise and practical execution across the full spectrum of these variables.
Liquid Injection Molding (LIM)
LIM is the ideal medical 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. And, because all of this takes place within a closed system, the process is extremely clean. In addition, Vesta’s LIM lines use fully automated robotic machines and semi-automatic equipment to create repeatable precision and manufacturing efficiencies.
Transfer Molding
For shorter production runs or when silicone gumstock is specified, Vesta 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.
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. So when your project calls for the insertion of ancillary components into the silicone, Vesta utilizes medical molding machines that are designed to create securely integrated molded entities.
