Silicone Extrusions
Custom-extruded silicone tubing for flexible medical designs
High-performance elastomers
shaped with precision
Silicone extrusion is a continuous manufacturing process used to create flexible, medical-grade tubing and profiles by forcing uncured silicone through a shaped die. The material is then cured through heat to form durable, biocompatible components with consistent cross-sectional geometry. This method supports single-lumen, multi-lumen, and complex profiles, and is widely used for implantables, fluid management, and delivery systems due to its precision, flexibility, and resistance to chemicals and temperature extremes.
