LSR Overmolding Machines and Metering & Mixing Systems

The MonoBiologics LSR overmolding machine range is engineered for medical and bioprocess hardware manufacturing environments that require controlled, repeatable silicone molding. Designed for use with liquid silicone rubber (LSR) materials, the overmolding presses provide stable clamp force and controlled thermal conditions to support consistent part quality without the complexity of hydraulic systems. Built for cleanroom and GMP manufacturing, these systems enable silicone overmolding without introducing unnecessary contamination risk or excessive process variability.

Supporting both process development and production-scale manufacturing, MonoBiologics overmolding presses are used for overmolding tubing, connectors, junctions, and hybrid assemblies where dimensional accuracy and material consistency are critical. The compact machine architecture and controlled platen heating support efficient mold temperature management, while the pneumatic actuation approach enables quiet, clean operation suitable for regulated manufacturing environments. This allows manufacturers to move from benchtop development to production using a consistent overmolding platform.

To ensure reliable material delivery, the overmolding press is paired with dedicated LSR metering and mixing systems designed to accurately meter, mix, and dispense two-part silicone materials at fixed ratios. These systems deliver consistent material preparation across a wide viscosity range, supporting stable shot-to-shot performance and repeatable molding results. Together, the overmolding press and metering/mixing systems provide a controlled silicone processing platform suited to medical device manufacturing, single-use component production, and other applications where process stability and repeatability are essential.
