Robust extrusion capabilities to support even the most complex of projects
Our expertise in extrusion fabrication was forged, in part, by our customers’ imagination and demand for precision. Our processes can be tailored to meet our customers’ needs, no matter how complex. This typically begins in our in-house tool room, where our team precision manufactures the die and mandrel. Post-processing extrusion capabilities include services such as post curing, cutting, spooling, printing, and drilling.
Extrusion capabilities to meet customer specifications
Medical disciplines such as cardiac rhythm management and interventional cardiology have driven efforts involving the increased complexity and miniaturization of silicone medical devices. As a long-term partner, we at Trelleborg Sealing Solutions have consistently developed extrusion technology required to meet the challenges of these disciplines.
Silicone foam products play a major role in ophthalmology. We have developed a proprietary blowing agent that allows us to produce closed-cell silicone sponge that can be extruded in various client-specified cross-sections. We offer foam rod and tubes, as well as foam-jacketed extrusions; in addition, pore size and foam density can be adjusted to meet your specifications.
Kink-Resistant Tubing (KRT)
Medical silicone tubing often acts as a pathway for the introduction or elimination of fluids from the body. To effectively serve this purpose, medical tubing must meet a number of mechanical and functional requirements including adequate hoop strength, sufficient stiffness during insertion, and the flexibility to bend around and conform to various anatomical features. Manufactured using a proprietary winding and over-jacketing process, Trelleborg’s KRT balances flexibility and hoop strength while guaranteeing open-lumen integrity.
Extruded ribbon can be a cost-effective alternative to silicone sheeting. We manufacture ribbon with a range of elastomeric properties and dimensions. Our continuous process allows extruded ribbon to be spooled onto various carrier substrates, which in turn can be subsequently punched or laser cut to form various components including check valves and other pressure sensitive medical devices
Trelleborg Healthcare & Medical’s GeoTrans ™ process allows for silicone tubing to change cross section during extrusion to eliminate molding and secondary bonding steps, allowing for a strong, hygienic design with a lower overall device cost. The technology is well suited for custom applications requiring precision tolerances.
With our GeoTransTM lumen transition technology, we produce tubes in which the single lumen tube transitions into a multi-lumen tube.
GeoTransTM Stop Lumen
Our GeoTransTM Stop Lumen Tubing eliminates the need for secondary operations such as applying a room temperature vulcanized silicone plug to close the lumen. Our single or multiple lumen tube can have one or more lumens stop and restart, depending on requirements.
GeoTransTM Bump Tapered Tubing
Our Bump or Tapered GeoTransTM tubing is used for applications requiring a variable outer diameter and either a constant or variable inner diameter. The variations and applications are endless. The bump/tapered tubing can be used for a catheter where the intravenous section is smaller, minimizing disruption in blood flow.
GeoTransTM Advanced Wound Drain Technology
GeoTransTM wound drains set the industry standards for function and reliability. Using patented GeoTransTM processes, we manufacture and stocks various sizes of both the 4 channel and saw-tooth design.
